camera_frame_cbycry_10bit_t

A frame descriptor for a YCbCr 4:2:2 packed frame type

Synopsis:

#include <camera/camera_api.h>
typedef struct camera_frame_cbycry_10bit_t {
    uint32_t height;
    uint32_t width;
    uint32_t stride;
} camera_frame_cbycry_10bit_t;

Data:

uint32_t height
The height of the image, in pixels.
uint32_t width
The width of the image, in pixels.
uint32_t stride
The number of bytes between the first pixel of the first row in memory and the first pixel of the second row in memory.

Stride is often called pitch.

Library:

libcamapi

Description:

Use this frame descriptor when CAMERA_FRAMETYPE_CBYCRY_10BIT is reported as the camera_frametype_t.

Each set of 2 pixel values in the CbYCrY frame is part of a macro-pixel. Each macro-pixel is made up of four components in the following order: a Cb (blue-difference chroma) component, a Y (luma) component, a Cr (red-difference chroma) component, and a Y (luma) component. Each macro-pixel is stored contiguously on the same line and each component is 10 bits zero-padded to 16 bits.

A macro-pixel is stored as follows: 
Bit:          0 1 2 3 4 5 6 7 8 9.....15 0123456789....15 0 1 2 3 4 5 6 7 8 9.....15 0123456789....15
Scanline n:   CbCbCbCbCbCbCbCbCbCb000000 YYYYYYYYYY000000 CrCrCrCrCrCrCrCrCrCr000000 YYYYYYYYYY000000 = 64 bits
