Bits 10:0 – IM_VSIZE[10:0]: Vertical Size of the Image Sensor [0..2047]

Vertical Size of the Image Sensor [0..2047]

IM_VSIZE = Vertical size - 1

Bit 11 – GS_MODE: Grayscale Pixel Format Mode

Grayscale Pixel Format Mode

ValueDescription
0

2 pixels per word.
1

1 pixel per word.

Bit 12 – RGB_MODE: RGB Input Mode

RGB Input Mode

ValueDescription
0

RGB 8:8:8 24 bits.
1

RGB 5:6:5 16 bits.

Bit 13 – GRAYSCALE: Grayscale Mode Format Enable

Grayscale Mode Format Enable

ValueDescription
0

Grayscale mode is disabled.
1

Input image is assumed to be grayscale-coded.

Bit 14 – RGB_SWAP: RGB Format Swap Mode

RGB Format Swap Mode

The RGB_SWAP has no effect when Grayscale mode is enabled.

ValueDescription
0

D7 → R7.
1

D0 → R7.

Bit 15 – COL_SPACE: Color Space for the Image Data

Color Space for the Image Data

ValueDescription
0

YCbCr.
1

RGB.

Bits 26:16 – IM_HSIZE[10:0]: Horizontal Size of the Image Sensor [0..2047]

Horizontal Size of the Image Sensor [0..2047]

If 8-bit Grayscale mode is enabled, IM_HSIZE = (Horizontal size/2) - 1.

Else IM_HSIZE = Horizontal size - 1.

Bits 29:28 – YCC_SWAP[1:0]: YCrCb Format Swap Mode

YCrCb Format Swap Mode

Defines the YCC image data.

Bits 31:30 – RGB_CFG[1:0]: RGB Pixel Mapping Configuration

RGB Pixel Mapping Configuration

Defines RGB pattern when RGB_MODE is set to 1.

If RGB_MODE is set to RGB 8:8:8, then RGB_CFG = 0 implies RGB color sequence, else it implies BGR color sequence.
