Bayer bit justification
Synopsis:
#include <sensor/sensor_api.h>
typedef enum {
SENSOR_BAYERJUSTIFY_RIGHT_BIT0LSB,
SENSOR_BAYERJUSTIFY_LEFT_BIT0LSB,
SENSOR_BAYERJUSTIFY_RIGHT_BIT0MSB,
SENSOR_BAYERJUSTIFY_LEFT_BIT0MSB
} sensor_bayerjustify_t;
Data:
- SENSOR_BAYERJUSTIFY_RIGHT_BIT0LSB
- Bit 0 is the least significant bit, and the bits are right-justified.
- SENSOR_BAYERJUSTIFY_LEFT_BIT0LSB
- Bit 0 is the least significant bit, and the bits are left-justified.
- SENSOR_BAYERJUSTIFY_RIGHT_BIT0MSB
- Bit 0 is the most significant bit, and the bits are right-justified.
- SENSOR_BAYERJUSTIFY_LEFT_BIT0MSB
- Bit 0 is the most significant bit, and the bits are left-justified.
Library:
libsensor
Description:
The Bayer bit justification indicates whether bit 0 is the least significant or most significant bit of the word, and also indicates whether the bits are justified towards the 0th bit (right-justified) or the Nth bit (left-justified). For example:
le = false
bpp = 10
packing = 16
cadence_length = 16
pixels_per_cadence = 1
format = SENSOR_BAYERFORMAT_RGGB
SENSOR_BAYERJUSTIFY_RIGHT_BIT0LSB would represent:
Bit: FEDCBA9876543210 FEDCBA9876543210
Scanline n: 000000RRRRRRRRRR 000000GGGGGGGGGG
Scanline n+1: 000000GGGGGGGGGG 000000BBBBBBBBBB
Note that the 0th bit in the word represents the least significant bit, and the bits are justified to the right of the word.
