camera_region_t

Updated: May 06, 2022

This structure is used to identify a subset of pixels in an image

Synopsis:

#include <camera/camera_api.h>
typedef struct {
    uint32_t left;
    uint32_t top;
    uint32_t width;
    uint32_t height;
    uint32_t extra;
} camera_region_t;

Data:

uint32_t left
The left coordinate of the region.

A value of 0 refers to the left-most column of the image.

uint32_t top
The top coordinate of the region.

A value of 0 refers to the top-most column of the image.

uint32_t width
The width of the region in pixels.
uint32_t height
The height of the region in pixels.
uint32_t extra
An additional application-dependent value that can be used to convey extra information about a region.

Typically, this extra information may be a weighting, ranking, or other application-specific value to apply when defining a set of regions.

Library:

libcamapi

Description:

Regions are used to report focus lock positions and to configure region-dependent focus, exposure, and white balance operations.
