Abstract
Disclosed in the present disclosure are an exposure control method, an exposure control device and an electronic device. The exposure control method includes the following. Scene data is processed to obtain a foreground part of a cached main image. A reference exposure is determined according to brightness information of the foreground part. A first exposure for a first image and a second exposure for a second image are determined according to the reference exposure. An imaging device is controlled to expose according to the reference exposure, the first exposure and the second exposure.
Claims20
A method of exposure control for controlling an imaging device to collect scene data, the scene data comprising a cached master image, the method comprising:
- processing the scene data to obtain a foreground part of the cached master image;
- determining a reference exposure based on brightness information of the foreground part;
- determining a first exposure for a first image and a second exposure a second image based on the reference exposure, the first exposure being less than the reference exposure, and the second exposure being greater than the reference exposure;
- and
- controlling the imaging device to expose based on the reference exposure, the first exposure and the second exposure.
An device for exposure control based on depth, for controlling an imaging device to collect scene data, the scene data comprising a cached master image, the device comprising a non-transitory computer-readable medium having computer-executable instructions stored thereon, and an instruction execution system which is configured by the instructions to implement:
- a processing module, configured to process the scene data to obtain a foreground part of the cached master image;
- a first determining module, configured to determine a reference exposure based on brightness information of the foreground part;
- a second determining module, configured to determine a first exposure for a first image and a second exposure for a second image based on the reference exposure, the first exposure for the first image being less than the reference exposure, and the second exposure for the second image being greater than the reference exposure;
- and
- a control module, configured to control the imaging device to expose based on the reference exposure, the first exposure and the second exposure.
An electronic device, comprising:
- an imaging device, configured to collect scene data, the scene data comprising a cached master image;
- and
- an exposure control device, comprising a non-transitory computer-readable medium having computer-executable instructions stored thereon, and an instruction execution system which is configured by the instructions to implement:
- a processing module, configured to process the scene data to obtain a foreground part of the cached master image;
- a first determining module, configured to determine a reference exposure based on brightness information of the foreground part;
- a second determining module, configured to determine a first exposure for a first image and a second exposure for a second image based on the reference exposure, the first exposure for the first image being less than the reference exposure, and the second exposure for the second image being greater than the reference exposure;
- and
- a control module, configured to control the imaging device to expose based on the reference exposure, the first exposure and the second exposure.
