Sensor Architecture 1600 (H) x 1200 (V) Active Pixels G G R B G G R B G G R B G G R B Pixel 1,1 4 Buffer Rows 2 Dark Rows Dual or Video L Video R 4 16 4 1600 4 16 4 Single 4 16 4 800 800 4 16 4 Output 4 Buffer Rows 4 Dark Rows There are 2 light shielded rows followed 1,208 photoactive rows and finally 4 more light shielded rows. The first 4 and the last 4 photoactive rows are buffer rows giving a total of 1,200 lines of image data. In the single output mode all pixels are clocked out of the Video L output in the lower left corner of the sensor. The first 4 empty pixels of each line do not receive charge from the vertical shift register. The next 16 pixels receive charge from the left light shielded edge followed by 1,608 photosensitive pixels and finally 16 more light shielded pixels from the right edge of the sensor. The first and last 4 photosensitive pixels are buffer pixels giving a total of 1,600 pixels of image data. In the dual output mode the clocking of the right half of the horizontal CCD is reversed. The left half of the image is clocked out Video L and the right half of the image is clocked out Video R. Each row consists of 4 empty pixels followed by 16 light shielded pixels followed by 800 photosensitive pixels. When reconstructing the image, data from Video R will have to be reversed in a line buffer and appended to the Video L data. There are 4 dark reference rows at the top and 2 dark rows at the bottom of the image sensor. The dark rows are not entirely dark and so should not be used for a dark reference level. Use the 16 dark columns on the left or right side of the image sensor as a dark reference. Of the 16 dark columns, the first and last dark columns should not be used for determining the zero signal level. Some light does leak into the first and last dark columns. Only use the center 14 columns of the 16 column dark reference. |
