camera_frame_crycby_t

Updated: May 06, 2022

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

Synopsis:

#include <camera/camera_api.h>
typedef struct {
    uint32_t height;
    uint32_t width;
    uint32_t stride;
} camera_frame_crycby_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, in memory, between the first pixel of the first row and the first pixel of the second row.

Stride is often called pitch.

Library:

libcamapi

Description:

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

Each set of two pixel values in the CrYCbY frame is part of a macro-pixel. Each macro-pixel is made up of four components in the following byte order: a Cr (red-difference chroma) component, a Y (luma) component, a Cb (blue-difference chroma) component, and a Y (luma) component. Each macro-pixel is stored contiguously on the same line and each component consumes eight bits.
