DAY_GAIN_THD

Description

Get or Set the sensor's gain threshold to enter the low light mode.

The video quality is poor due to much noise when the light condition is bad. To have better video quality, the sensor will increase its gain to improve the video quality. However, the gain might be saturated and could not improve the quality anymore. The camera could monitor the gain situation to know the lighting condition. If the lighting condition was poor (gain is very high), it could remove the color information from the image to filter the color noise. When the lighting condition get better (gain was dropped), the sensor could restore the original image setting to get the colorful picture. This URL sets the gain threshold to trigger the low light condition.

This URL will not take effect if the CDS is used for low light detection. Please refer the Camera Setup Design Specification for further details.

The error message will be returned if the encoder does not support this URL.

Input Argument

Percentage of the gain. (0~100),
where 100: disable gain detection algorithm.
