Diagonal 8mm (Type 1/2) Progressive Scan CCD Image Sensor with Square Pixel for Color Cameras interline CCD solid-state image sensor with a square pixel array and 1.45M effective pixels. Progressive scan allows all pixels' signals to be output independently within approximately 1/7.5 second. Also, the adoption of high frame rate readout mode supports 30 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 re productivity 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. • Progressive scan allows individual readout of the image signals from all pixels. * High horizontal and vertical resolution (both approx. 800TV-lines) still image without a mechanical shutter. • Supports high frame rate readout mode (effective 256 lines output, 30 frame/s) • Square pixei • Horizontal drive frequency: 14.318MHz (Reset gate and substrate bias need no adjustment.) • 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 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: Optical black position 1360 (H) x 1024 (V) approx. 1.40M pixels (7.959mm diagonal) Horizontal (H) direction: Front 2 pixels, rear 40 pixels Vertical (V) direction: Front 8 pixels, rear 2 pixels Wfine CCD is a registered trademark of Sony Corporation.

The diagram below shows the output methods for the following two readout modes. Progressive scan mode High frame rate readout mode Note) Blacked out portions in the diagram indicate pixels which are not read out. Output starts from the line 1 in high frame rate readout mode. 1. Progressive scan mode In this mode, all pixel signals are output in non-interlace format in 1/7.5s. The vertical resolution is approximately 800TV-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...
