ICX204AK Diagonal 6mm (Type 1/3) Progressive Scan CCD Image Sensor with Square Pixel for Color Cameras Description The ICX204AK is a diagonal 6mm (Type 1/3) interline CCD solid-state image sensor with a square pixel array and 800K effective pixels. Progressive scan allows all pixels' signals to be output independently. Also, the adoption of high frame rate readout mode supports 60 frames per second. This chip features an electronic shutter with variable charge-storage time which makes it possible to realize full-frame still image without a mechanical shutter. High resolution and high color reproductivity are achieved through the use of R, G, B primary color mosaic filters. Further, high sensitivity and low dark current are achieved through the adoption of HAD (Hole-Accumulation Diode) sensors. This chip is suitable for applications such as electronic still cameras, PC input cameras, etc. 16 pin DIP (Plastic) Features • Progressive scan allows individual readout of the image signals from all pixels. • High horizontal and vertical resolution (both approx. 600TV-lines) still image without a mechanical shutter. • Supports high frame rate readout mode (effective 256 lines output, 15MHz drive: 45 frame/s, 20MHz drive: 60 frame/s) • Square pixel • Horizontal drive frequency: Typ.: 15MHz, Max.: 20MHz • No voltage adjustments (reset gate and substrate bias are not adjusted.) • R, G, B primary color mosaic filters on chip • High resolution, high color reproductivity, high sensitivity, low dark current • Low smear, excellent antiblooming characteristics • Continuous variable-speed shutter • Recommended range of exit pupil distance: –20 to –100mm Pin 1 V 3 Pin 9 H 40 Optical black position (Top View) Device Structure • Interline CCD image sensor • Image size: • Total number of pixels: • Number of effective pixels: • Number of active pixels: • Chip size: • Unit cell size: • Optical black: • Number of dummy bits: • Substrate material: Diagonal 6mm (Type 1/3) 1077 (H) × 788 (V) approx. 850K pixels 1034 (H) × 779 (V) approx. 800K pixels 1024 (H) × 768 (V) approx. 790K pixels (diagonal 5.952mm) 5.80mm (H) × 4.92mm (V) 4.65µm (H) × 4.65µm (V) Horizontal (H) direction: Front 3 pixels, rear 40 pixels Vertical (V) direction: Front 7 pixels, rear 2 pixels Horizontal 29 Vertical 1 Silicon 2 7 ∗ Wfine CCD is a registered trademark of Sony Corporation.

Output starts from the line 7 in high frame rate readout mode. ICX204AK 1. Progressive scan mode In this mode, all pixel signals are output in non-interlace format in 1/20s. The vertical resolution is approximately 600TV-lines and all pixel signals within the same exposure period are read out simultaneously, making this mode suitable for high resolution image capturing. 2. High frame rate readout mode All effective areas are scanned in approximately 1/60s by reading out one line for every three lines. The vertical resolution is approximately 200TV-lines. This readout mode emphasizes processing speed over vertical resolution. – 11 – 11 Page
