3 block level description
3.1 pixel array structure
The OV2655 sensor has an image array of 1624 columns by 1224 rows (1,987,776 pixels). figure 3-1 shows a
) cross-section of the image sensor array.
ial ly The color filters are arranged in a Bayer pattern. The primary color BG/GR array is arranged in line-alternating fashion.
Of the 1,987,776 pixels, 1,920,000 (1600x1200) are active pixels and can be output. The other pixels are used for black
level calibration and interpolation.
n The sensor array design is based on a field integration read-out system with line-by-line transfer and an electronic shutter
with a synchronous pixel read-out scheme.
