Command Description
4BH:
GainB3[7..0]
[Preset_3 white balance (Blue gain)] Initial data: 0, data range: 0 to 255
Sets the Blue gain for the preset_3 white balance.
Blue of the camera output image data = (CCD_B – CLAMP Level) x (1+ GainB3[7..0] / 64) + CLAMP Level
* CCD_B: Blue of the CCD output image data
* CLAMP Level: Clamp level (The calculated value of 38H)
4CH:
GainGb3[7..0]
[Preset_3 white balance (Gb gain)] Initial data: 0, data range: 0 to 255
Sets the Gb gain for the preset_3 white balance.
Gb of the camera output image data = (CCD_Gb – CLAMP Level) x (1+ GainGb3[7..0] / 64) + CLAMP Level
* CCD_Gb: Gb of the CCD output image data
* CLAMP Level: Clamp level (The calculated value of 38H)
4EH: [7..0]
4FH: [15..8]
[Bright level threshold fro auto white balance process] Initial data: 3,072, data range: 0 to 4,095
Sets the bright level threshold for auto white balance process.
Auto white balance process uses the color information of the pixel (the brightness of the pixel that is greater than this
value).
50H: [7..0]
51H: [15..8]
[Y_offset for AOI]
Initial data: 0, data range: 2 ≤ “Y_ Height” ≤ 768
Sets the Y_offset (the vertical start position of the image for the AOI)
52H: [7..0]
53H: [15..8]
[Height for AOI]
Initial data: 768, data range: 2 ≤ “Y_ Height” ≤ 768
Sets the height (the vertical size of the image for the AOI)
54H: [7..0]
55H: [15..8]
[X_offset for AOI]
Initial data: 0, data range: 8 ≤ “Y_ Height” ≤ 1,024
Sets the X_offset (the horizontal start position of the image for the AOI)
56H: [7..0]
57H: [15..8]
[Width for AOI]
Initial data: 1,024, data range: 8 ≤ “Y_ Height” ≤ 1,024
Sets the width (the horizontal size of the image for the AOI)
58H: [7..0]
59H: [15..8]
[Vertical_1 position for the white balance area]
Initial data: 0, data range: 0 to 767
Sets the vertical 1 position, which is the vertical start position for the white blance area.
This area is used for the gain calculation of the auto white balance and the push-to-set white balance.
