hi_isp_ae_hist_config

Description

Defines the sampling point mode for global histogram statistics.

Definition

typedef struct { 
    hi_isp_ae_hist_skip hist_skip_x;
    hi_isp_ae_hist_skip hist_skip_y;

Members

Member	Description
hist_skip_x	Horizontal sampling points for histogram statistics. The value 0 indicates that every pixel is sampled for statistics, the value 1 indicates that every two pixels are sampled for statistics, and the rule applies. This parameter can be set to 0 only when FourPlaneMode is enabled.
hist_skip_y	Vertical sampling points for histogram statistics.
hist_offset_x	Horizontal start point for histogram statistics.
hist_offset_y	Vertical start point for histogram statistics.

Restrictions

The structure can be properly configured based on the Bayer data format input by the sensor so that only the data of a component is collected for the global histogram statistics.
In RGBIR mode, you are advised to include only the G component in the global histogram statistics by setting the data structure based on the Bayer data format of the RGBIR sensor.
When configuring hist_config, you need to disable the large-area single-color judgment function of the Ascend AE.
