voice we developed this 4m-pixel type 1/2.7 ccd that achieves both a high pixel count still picture and high-quality moving picture at the same time, and also achieves fur- ther miniaturization. to respond to market needs for miniaturization and higher pixel counts, we took maximum advantage of sony? fine fabrication technologies and achieved the industry? smallest pixel size. i strongly recommend that you consider developing new products based on this device, which combines both the latest technologies and functions. high-resolution 4.11m-pixel diagonal 6.75 mm (type 1/2.7) color ccd for consumer digital still cameras supports 30 frames/s vga moving picture imaging ICX488DQ/dqf the desires for higher resolution and further miniaturization are grow- ing along with the increasingly widespread use of consumer digital still cameras. to respond to these desires, sony has now developed a new 4.11m- pixel diagonal 6.75 mm (type 1/2.7) interlaced ccd, the ICX488DQ/ dqf. the ICX488DQ/dqf achieves both higher resolution and miniaturiza- tion by achieving the industry? smallest pixel size of 2.35 m. sony? unique horizontal and vertical pixel addition technology allows the ICX488DQ/dqf to provide both 4m-pixel class still picture and vga moving picture imaging at 30 frames/s. ICX488DQ: primary color filters, 24-pin dip ICX488DQf: primary color filters, 24- pin sop diagonal 6.75 mm (type 1/2.7) optical size and 4.11m effective pixels (2344h 1752v) the industry? smallest pixel size (2.35 m unit pixel) 3-field readout method supports 30 frames/s vga moving picture imaging the ICX488DQ/dqf is a diagonal 6.75 mm (type 1/2.7) 4.11m-effective pixel ccd image sensor developed for use in high-resolution consumer digital still cam- eras. used with a mechanical shutter, the ICX488DQ/dqf provides high-resolution image capture. table 1 presents the pixel structure used in the ICX488DQ/dqf, and table 2 presents its imaging characteris- tics. the industry? smallest pixel size figure 1 presents sony? consumer digi- tal still camera ccd lineup. although the ICX488DQ/dqf corresponds to an increased pixel count version of sony? earlier type 1/2.7 3.24m-pixel icx432dq/dqf, sony has developed the industry? smallest pixel (with a unit pixel size of 2.35 m) by adopting the latest fine fabrication technologies, and thus suc- ceeds in achieving both higher resolution and miniaturization at the same time. this allows the implementation of a 4m-pixel digital still camera from a design using the icx432dq/dqf without changing the optical system. high saturation signal to increase the dynamic range, the ICX488DQ/dqf adopts the same 3-field readout system used in the icx432dq/ dqf. this readout mode allows finer design rules to be used in the vertical transfer block, which in turn allows the photodiode block to be made larger. the ICX488DQ/dqf achieves a saturation signal of 385 mv despite miniaturization to a 2.35 m unit pixel size. (see table 2.) vga moving picture imaging at 30 frames/s since the ICX488DQ/dqf adopts sony? unique horizontal and vertical pixel addi- tion technology, it can add together 4 pix- els internally to the ccd itself and thus achieve a four times higher imaging sen- sitivity. in the 4/6-line readout mode (with horizontal addition), the ICX488DQ/dqf achieves both 30 frames/s high-speed im- aging at high resolution (vga: 640 480 pixels). thus the ICX488DQ/dqf achieves both high pixel count still pic- ture and high-quality moving picture. it also features an extensive set of readout modes, including 2/6-line readout mode that allows high-speed shutter operation, and partial scan modes designed for even higher speed af control. system ic sony also provides the cxd3629ga driver timing generator ic that includes built-in horizontal and vertical drivers. in addition to a vga equivalent moving pic- ture mode, this ic also supports high frame rate readout mode and af mode as well.
