Mode C[1] :
color
(color select) <
default value : 0b>
This bit selects color mode or monochrome mode. Default value means color image sensor and all
three ADCs are used for Bayer RGB color pattern respectively, then RGB gains are controlled
independently. But when set this to one, i.e. monochrome mode, just single ADC is used for all pixels
regardless RGB color.
At the monochrome mode all pixels are controlled by ‘G’ gain only. ‘R’ and ‘B’ gain are not used. In case
of monochrome image sensor, this bit should be set to ‘1’ get the good image and to simplify the sensor
control.
(4) Row start address Register
Higher byte : Address 10h, default : 00h, R/W)
Lower byte : Address 11h, default : 06h, R/W)
Define window start position row start address of display window. Should be programmed with value between
6 and 306.
(5) Column start address Register
Higher byte : Address 12h, default : 00h, R/W)
Lower byte : Address 13h, default : 06h, R/W)
Define window start position column address of display window. Should be programmed with value between
6 and 406.
(6) Window Height address Register
Higher byte : Address 14h, default : 01h, R/W)
Lower byte : Address 15h, default : 2Eh, R/W)
Define display window height. If you need smaller display window height, decrease the value.
Window end position row address = row start address + window height address –1
(7) Window width address Register
Higher byte : Address 16h, default : 01h, R/W)
Lower byte : Address 17h, default : 92h, R/W)
Define display window width. If you need smaller display window width, decrease the value.
Window end position column address = column start address + window width address -1
Note : Display window programming.
