ICX252AK Diagonal 8.933mm (Type 1/1.8) Frame Readout CCD Image Sensor with Square Pixel for Color Cameras Description The ICX252AK is a diagonal 8.933mm (Type 1/1.8) interline CCD solid-state image sensor with a square pixel array and 3.24M effective pixels. Frame readout allows all pixels' signals to be output independently within approximately 1/4.28 second. Also, number of vertical pixels decimation allows output of 30 frames per second in high frame rate readout mode. Ye, Cy, Mg, G complementary color mosaic filters are used as the color filters, and at the same time high sensitivity and low dark current are achieved through the adoption of Super HAD CCD technology. This chip is suitable for applications such as electronic still cameras, etc. 20 pin DIP (Plastic) Pin 1 Features • Supports frame readout • High horizontal and vertical resolution • Supports high frame rate readout mode: 30 frames/s, V AF1 mode: 60 frames/s, 50 frames/s, AF2 mode: 120 frames/s, 100 frames/s • Square pixel 4 • Horizontal drive frequency: 18MHz • No voltage adjustments (reset gate and substrate bias are not adjusted.)

Readout modes list The following readout modes are possible by driving the image sensor at the timing specifications noted in this Data Sheet. Mode name Frame rate Number of output effective lines Frame readout mode NTSC mode PAL mode 4.28 frame/s 4.16 frame/s 1550 (Odd 775, Even 775) 1550 (Odd 775, Even 775) High frame rate readout mode NTSC mode PAL mode 30 frame/s 25 frame/s 258 258 AF1 mode NTSC mode PAL mode 60 frame/s 50 frame/s See Page.12 See Page.12 AF2 mode NTSC mode PAL mode 120 frame/s 100 frame/s See Page.12 See Page.12 2.

Frame readout mode In this mode, all pixel signals are divided into two fields and output. All pixel signals are read out independently, making this mode suitable for high resolution image capturing. 2. High frame rate readout mode Output is performed at 30 frames per second by reading out 4 pixels for every 12 vertical pixels and adding 2 pixels in the horizontal CCD. The number of output lines is 258 lines. This readout mode emphasizes processing speed over vertical resolution. – 11 – 11 Page
