Abstract
The present disclosure relates to systems and methods for adjusting exposure parameter(s) of a capture device. The systems and methods may obtain a target region within an image captured by the capture device. The systems and methods may determine a current brightness of the target region based on gray information of the target region, and determine a target brightness of the target region based on the current brightness of the target region. The systems and methods may then determine one or more exposure parameters of the capture device based on the target brightness of the target region.
Claims22
A method for adjusting an exposure parameter implemented on a computing device having at least one processor, at least one computer-readable storage medium, and a communication platform connected to a network, comprising:
- obtaining a target region within an image captured by a capture device;
- determining, based on gray information of the target region, a current brightness of the target region;
- determining, based on the current brightness of the target region, a target brightness of the target region;
- and
- determining, based on the target brightness of the target region, one or more exposure parameters of the capture device.
6-8. (canceled)
A system for adjusting an exposure parameter, comprising:
- at least one storage device storing a set of instructions;
- at least one processor in communication with the at least one storage device, wherein when executing the set of instructions, the at least one processor is configured to cause the system to:
- obtain a target region within an image captured by a capture device;
- determine, based on gray information of the target region, a current brightness of the target region;
- determine, based on the current brightness of the target region, a target brightness of the target region;
- and
- determine, based on the target brightness of the target region, one or more exposure parameters of the capture device.
A non-transitory computer-readable storage medium, comprising at least one set of instructions, wherein when executed by at least one processor of a computing device, the at least one set of instructions directs the at least one processor to perform acts of:
- obtaining a target region within an image captured by a capture device;
- determining, based on gray information of the target region, a current brightness of the target region;
- determining, based on the current brightness of the target region, a target brightness of the target region;
- and
- determining, based on the target brightness of the target region, one or more exposure parameters of the capture device.
