Service Information 8-1. MUC Removal The IC socket for mounting the MUC on the MCB100/101 is not designed for repeated insertion and removal. Therefore, avoid frequent MUC replacement and use a special tool when removing the MUC. 8-2. MUC Mounting Align MUC Pin 1 (marked with a small square pattern on the side of the case) with IC socket Pin 1 (indicated by a square mark in the IC socket land on the board) when mounting the MUC. -4- MCB100/101 Fig. 8-1.

Lens Dust and Dirt Protection Operate in clean environments. Also, do not either touch the lens by hand or allow any object to come into contact with the lens surface. Should dirt stick to the lens surface, blow it off with an air blower. Clean with a cotton bud and ethyl alcohol if grease stained. Be careful not to scratch the lens. 9. Description of Circuits 9-1. MUC Block The MUC contains a CCD image sensor that changes light into electric signals. A total of 192,786 photo sensors arranged on the chip surface of this CCD image sensor: 381 in the horizontal direction and 506 in the vertical direction. Of these, 362 in the horizontal direction and 492 in the vertical direction for a total of 178,104 photo sensors are valid pixels which output signals according to the brightness. The photo sensors convert light into electric charges that correspond to the brightness. These converted electric charges are read from the photo sensors to the transfer block and then led sequentially to the output block. The transfer block has 506 vertical transfer blocks in the vertical direction of the screen, and one horizontal transfer block. The charges converted by the photo sensors are transferred to the vertical transfer blocks adjoining each photo sensor once every field, and these charges are then transferred sequentially to the horizontal transfer block. The horizontal transfer block sends the charges to the output block where they are converted to a voltage Cy Ye Mg Ye Mg Ye G Cy G Cy G Cy Mg Ye Mg Ye Mg Ye G Vertical register G Cy G Cy Mg Horizontal register Fig. 9-1. CCD Image Sensor -5- MCB100/101 The output signal from the CCD image sensor passes through a buffer and is then output from CCD OUT of the MUC. As this output signal is modulated by a clock of approximately 6.75MHz, the video signal is separated from this signal and sample-and-hold works to eliminate low frequency noise. The separated video signal passes through the AGC amplifier, is preblanked and clamped, and is then output from SHOUT. SHOUT is directly connected to SHIN, and the signal input from SHIN is A/D converted and processed as a digital signal. The signal processing block first clamps the optical black to the reference, and then passes the signal through two 1H delay lines in order to achieve synchronization. (The current, 1H previous, and 2H previous lines are synchronized.) Luminance (Y) signal processing mainly uses the 1H previous signal. The signal from the CCD image sensor has a chroma component, so this component is eliminated, gamma correction is applied, and setup, blanking and SYNC are added to create the Y signal. Chroma signal processing uses the current and 2H previous signals added together and the 1H previous signal. These signals are phase separated, band limited, and then broken down into R, G and B using a matrix. The white balance of these R, G and B signals is controlled by the AWB controller and then gamma correction is performed to form the R-G and B-G signals. Next, the clock for these R-G and B-G signals is changed to 14.31818MHz (4Fsc), the hue and gain are controlled, blanking and burst signals are added, and the signals are modulated at 3.58MHz. The Y and C signals are D/A converted and output from IOY and IOC as currents. The MUC's internal timing generator generates the pulses necessary for driving the CCD image sensor and for signal processing. A built-in 27MHz (OSC) oscillation inverter is located between OSCI and OSCO, and an oscillation crystal vibrator, load capacitance and feedback resistance are connected to these pins to comprise the oscillation circuit. The 27MHz generated here is input to CK and used to generate the various pulses in sync with the HD and VD generated by the signal processing block. The MUC's internal signal processing block inputs the 13.5MHz (MCK = OSC/2) generated by the timing generator in order to generate the pulses required to create the NTSC video signal. The electronic shutter is realized by controlling the accumulation time by superimposing the electric-charge sweep pulse SUBOUT (amplitude approximately 23V) onto the CCD image sensor substrate voltage (VSUB). The electric-charge sweep pulse SUBOUT is superimposed onto DC voltage DCOUT and then input to SUBIN. The electric-charge sweep pulse SUBOUT is output from the timing generator block in accordance with the shutter speed calculated by the MUC's internal AE controller. The voltage (VSUB value) applied to SUBIN differs for each individual MUC, and must be adjusted in the range of +5 to +12.75V. This voltage is indicated in symbol form on the rear surface of the MUC. The MUC has a built-in DC amplifier between DCIN and DCOUT. DC voltage controlled in the range of approximately 0 to 5V is input from the EVR D/A to DCIN, and DCIN is adjusted to the indicated VSUB value. 9-2. EEPROM/EVR The EVR generates various DC voltages such as the AGC control voltage used by the MUC and the VSUB voltage of the CCD image sensor. The EEPROM stores the parameters needed for MUC operation. 9-3. VIDEO Output Block The Y signal of the MUC passes through an LPF to eliminate the digital noise. The C signal is modulated by a rectangular wave and shaped into a sine wave. After that, the Y and C signals are mixed, the level is compensated and the impedance is converted to 75 by the video driver, and the signal is output. 9-4. Power Supply Block Four power supplies: -8V, +3.3V, +5V and +15V are required to drive the MUC. The -8V and +15V supply voltages are created from the +5V by a DC/DC converter, and the +3.3V is created by the Pin 3 regulator. -6- MCB100/101 10. Description of Functions 10-1. Operation During Power-on Operation from the field after the power is turned on and clear is released is as follows. Table 10-1. Operation During Power-on Field 1 2 3 4 5 6 7 8 10-2. AE 10-2-1. Operation AE is performed by the electronic shutter and AGC control. First the AGC gain is set to the minimum limit and exposure control is performed with the electronic shutter. When exposure is insufficient even with the maximum exposure time, the AGC gain is controlled. When exposure is excessive, first the AGC gain is lowered. Then, if exposure is still excessive even at the minimum gain, the electronic shutter operates. 10-2-2. Flickerless Mode (Normally OFF) Setting FLON (CAT8, byte 4, bit 0) to "1" results in flickerless mode. In this mode, the electronic shutter speed is fixed to 1/100 s to reduce the flicker of fluorescent lights. AE operation is performed by only AGC control. 10-2-3. Backlight Compensation (Normally ON) Setting BLCOF (CAT8, byte 4, bit 1) to "1" deactivates the backlight compensation function. Backlight compensation is performed through a combination of the following two types. 10-2-4. Weighted Average Backlight Compensation The screen is divided into five photometry windows and the integrated luminous intensity values for each window are multiplied by weighting values to obtain a weighted average. This method is suited for cases where the main subject is fixed within the screen. Window 0 Operation Check for EEPROM presence. Check address 0 (h), then read data from the EEPROM to the buffer. Read data from the EEPROM to the buffer. Read data from the EEPROM to the buffer. Read the buffer data to the internal registers. Read the gain and hue for the 1st quadrant. Read the gain and hue for the 2nd quadrant. Read the gain and hue for the 3rd quadrant. Read the gain and hue for the 4th quadrant. Start internal controller processing. Normal status Description If the data is 9D (h), the EEPROM is valid and bytes 1 to 32 of the data are loaded to the buffer. Bytes 33 to 64 are loaded to the buffer. Bytes 65 to 96 are loaded to the buffer. The parameters for the internal controller are initialized by the EEPROM contents. Window 2 Window 4 Window 3 Window 1 Fig. 10-1. AE Photometry Windows -7- MCB100/101 10-2-5. Histogram Backlight Compensation (Normally OFF) When the subject has only a slightly darker luminance than the overall screen, backlight compensation is performed through exposure compensation by applying the appropriate luminous intensity to the dark areas. This method is characterized by the fact that it is relatively unaffected by subject position movement, and is suited for cases where the main subject moves about actively within the screen. The backlight compensation level can be adjusted by [AE] BLC (SPEC code). Also, histogram backlight compensation operation can be turned on and off by [AE] HIST (SPEC code). Fig. 10-2. Example of Backlight Subject Note) Compensation may be insufficient when the background is extremely bright. Also, the backlight judgment may be difficult for some subjects with the result that AE operation appears to oscillate. 10-2-6. Parameter Reference (SPEC Codes) Table 10-2.

AWB 10-3-1. Operation Auto trace or all pull-in white balance can be selected by AWB2 (CAT8, byte 4, bit 6). (However, AWB1 and AWB3 = "0") * Auto trace Auto trace uses a feedback system. The color temperature range is limited by the pull-in window setting. * All pull-in Pull-in is performed at a faster operating speed than auto trace without pull-in window, response time or other limitations. 10-3-2. Pull-in Range AWB sets a pull-in window that follows the black body radiation curve. The standard setting for the pull-in color temperature range (R-B axis direction) is approximately 2,500K to 9,500K. The pull-in color temperature ranges for each pull-in window are as shown in the table below. The window is selected by [AWB] FRM (SPEC code) described hereafter. Table 10-9. Pull-in Color Temperature Ranges for Different Pull-in Windows Window Standard window Small window Large window Minimum pull-in color temperature approximately 2,500K approximately 2,800K approximately 2,400K Maximum pull-in color temperature approximately 9,500K approximately 8,500K approximately 11,000K When [AWB] FRM (SPEC code) is 12 (h), the window is canceled and pull-in operation is performed for any subject. - 10 - MCB100/101 Pull-in window image Black body radiation curve Fig.10-4.

Aperture Correction Suppress This suppresses the aperture correction level in accordance with the AGC gain. - 12 - MCB100/101 10-5. Serial Communication 10-5-1. Interface Circuit The MUC does not have a built-in RS232C level shift circuit, so a separate level shift circuit such as the MCB100EVB is required. 10-5-2. Communication Method Communication is performed by the full-duplex start-stop sync method which conforms to RS232C. The communication speed is 9,600bps, and the communication settings are "data length: 8 bits, parity: none, start bit: one bit, stop bit: one bit, flow control: none". 10-5-3. Communication Timing The MUC fetches data in 8-bit units at the timing determined by the communication speed from the fall of SI. The serial output is output in sync with the serial input. The communication data is LSB first. (BYTE1) SI ST bit0 bit1 bit6 bit7 SP ST Fetch timing SO ST bit0 bit1 bit6 bit7 SP ST bit0 bit1 bit6 bit7 SP bit0 bit1 (BYTE N) bit6 bit7 SP Start bit Stop bit Fig. 10-5. Communication Timing 10-5-4. Communication Format Data is sent in category units. The number of bytes to be transmitted is sent in the first byte, the category No. is sent in the second byte, and the data for each category is sent in the third and subsequent bytes. The first byte of the serial output is a flag indicating the status of the MUC's internal buffer. If the communication interval between category units is one field or more, there is no need to read this flag. When this flag is "1", the MUC's internal buffer is full and subsequent communication is ignored. SI N+1 CATEGORY BYTE1 BYTE2 BYTE N SO FLAG DATA1 DATA2 DATA N Fig. 10-6. Communication Format 10-5-5. Notes on Communication Leave an interval of at least one field or more between different category data. 10-5-6. Serial Output Data Limitations The MUC's internal output buffer has a capacity limit of 32 bytes. Therefore, serial output data for categories other than categories 5, 6 and 10 do not fit in the output buffer, so sometimes correct values may not be obtained. When serial output for categories other than categories 5, 6 and 10 must be obtained correctly, this data should be read out by the microcomputer in consideration of the communication prohibited interval. The communication prohibited interval is the approximately 4H interval before the fall of SCSBUSY. SCSBUSY is output from the VD pin when VDBUSY (CAT1, byte 13, bit 6) is "1". - 13 - MCB100/101 10-6.

Communication with the EEPROM 10-8-1. Communication Timing Communication to peripheral ICs is performed every field in the order of MUC internal EVR EEPROM. EEPROM communication is performed only when the "write enable" or "write" commands are sent. 5H (6H)1 3H SCSBUSY2 CSEVR CSROM Fig. 10-7. Communication Timing with Peripheral ICs 1 1 When the "write enable" command is sent. Values in parentheses are for when the "write" command is sent. 2 Data is output from the VD pin when VDBUSY (CAT1, byte 13, bit 6) is "1". When the "read" command is sent, 32 bytes of data are read continuously from the EEPROM during one field. At this time, communication is not performed with the MUC's internal circuits and the EVR. 83H SCSBUSY CSEVR CSROM 1 2 3 31 32 Fig. 10-8. Communication Timing with Peripheral ICs 2 - 20 - MCB100/101 10-8-2. Communication Parameters The communication settings are performed by bytes 5, 6, 7 and 8 of category 8. The EEPROM allows two bytes of data to be written per address, but the MUC uses only the first byte of data. Therefore, when writing data, write the same data in both the first and second bytes. Byte 5 Table 10-17. Byte 5 Parameters Bit 0 1 3 4 5 6 7 Parameter E2WR E2WEN E2RSW E2RAL1 E2RAL2 E2RAL3 E2RAL4 Function Writes the byte 8 data at the byte 7 address. Sends the write enable command.

When reading the data from addresses 20 (h) to 3F (h). When reading the data from addresses 40 (h) to 5F (h). When reading the data from addresses 60 (h) to 7F (h). Read command The address is automatically set by the MUC. Comment Note) Set one of these bits to "1". Data is read from the EEPROM from the field two after the above settings are sent. If the E2RALn setting is left as "1", data is read each field. To stop reading data, set E2RALn to "0". Be sure to stop the EEPROM read communication before reading the read EEPROM data from the serial output. The data read from the EEPROM is output as normal serial output (categories 5, 6 and 10) while E2RSW is "1". The relationship between the EEPROM address and the serial output categories and bytes is as shown in the table below. Table 10-20.

Adjust [AWB] USRR and [AWB] USRB (SPEC codes) to align the start point with white (the center of the vector scope). 5. Set the [AWB] USRR and [AWB] USRB values at that point to [AWB] PRER and [AWB] PREB (SPEC codes). 6. Return [AWB] RSFT, [AWB] BSFT, [AWB] USRR and [AWB] USRB to their recommended values (03 (h), 02 (h), 4C (h) and 58 (h), respectively). 7. Write the values to the EEPROM. When the system is booted following this operation, AWB operates from the condition where the white balance is aligned with the reference light source. Note that if values that deviate greatly from the black body radiation curve are written to [AWB] PRER and [AWB] PREB, AWB may not activate. R-Y B-Y Start point Fig. 11-2.

Therefore, care should be taken to ensure a safe design in consideration of the following items. 1. Operating temperature Make sure that the temperature inside the equipment does not exceed the operating temperature. 2. CCD light resistance Imaging highly luminous subjects such as the sun for short periods, or fixed imaging of even relatively low luminosity subjects for extended periods will discolor the on-chip color filters of the CCD. Avoid use under these conditions, as the on-chip color filters cannot be guaranteed against discoloration occurring under these circumstances. Be sure to check the operating environment beforehand and to take appropriate protective measures. 3. Mounting method The MCB100/101 does not have a dustproof or waterproof structure. In particular, it may not be possible to remove dust or dirt entering the optical aperture, so attaching a transparent cover in the manner of (A) in the figure below is recommended. (A) Transparent cover Outer cover Mounting screw Substrate MUC 4. Preventing damage from electrostatic discharge The ICs mounted on the MCB100/101 are easily damaged by static electricity. Therefore, be sure to take the following protective measures and to handle the MUC in the same manner as a semiconductor device in order to prevent electrostatic discharge. a) Either handle bare handed or use non-chargeable gloves, clothes or material. Also use conductive shoes. b) When handling directly use an earth band. c) Install a conductive mat on the floor or working table to prevent the generation of static electricity. d) Ionized air is recommended for discharge when handling the MCB100/101. 5. Storage and operating environment cautions Avoid storage or use under harsh environments subject to high temperatures, high humidity, dust, etc., or where water or humidity may cause condensation. 6. Mechanical strength The MCB100/101 is a precision optical part, so care should be taken not to apply excessive mechanical shocks or force. 7. Socket insertion and removal The mechanical strength of the MUC insertion/removal socket is guaranteed for up to five vertical insertions and removals. Therefore, repeated insertion and removal should be avoided as much as possible. 8. Modifications Do not modify the MCB100/101, as it cannot be guaranteed in these cases. 9. Safety standards The MCB100/101 is a partially fabricated item, and as such safety standards are not prescribed. Users should ensure that finished products using the MCB100/101 conform to applicable safety standards. - 28 - Package Outline Unit: mm MCB100 PWB 40 18 0.2 O2.1 56 41 40 57 8 25 9 24 31.3 0.2 16.8 0.2 36.5 64 1 2.5 0.1 2.5 0.1 34.5 0.2 3.0 PACKAGE STRUCTURE (HYBRID IC) Glass fiber / Epoxy (FR-4) CONNECTOR 12.07g Printed Wiring Boad MATERIAL I/O MCB100/101 MASS 0.8 5.5 - 29 - 8.4 3.7 12.9 O2.1X2.5 (Elongated Hole) Package Outline Unit: mm MCB101 PWB 40 18 0.2 34.5 0.2 3.0 O2.1 56 40 41 57 64 8 25 9 24 31.3 0.2 16.8 0.2 36.5 1 2.5 0.1 2.5 0.1 PACKAGE STRUCTURE (HYBRID IC) Glass fiber / Epoxy (FR-4) CONNECTOR 12.07g Printed Wiring Boad MATERIAL I/O MASS 0.8 5.5 - 30 - 9.6 3.7 14.1 O2.1X2.5 (Elongated Hole) MCB100/101 |
