Abstract
An imaging control method is provided. The method may include obtaining a current image generated based on an exposure parameter, wherein the current image includes a plurality of pixels; determining a plurality of target pixels or target pixel groups from at least portion of the plurality of pixels; determining a statistic representation based on target pixels or target pixel groups; determining a characteristic feature based on the statistic representation; and, updating the exposure parameter, based on the characteristic feature, to generate an updated image.
Claims21
An imaging control method, comprising:
- obtaining a current image generated based on an exposure parameter, wherein the current image includes a plurality of pixels;
- determining a plurality of target pixels or target pixel groups from at least portion of the plurality of pixels;
- determining a statistic representation based on the plurality of target pixels or the target pixel groups;
- determining a characteristic feature based on the statistic representation;
- and
- updating the exposure parameter, based on the characteristic feature, to generate an updated image.
A system configured to control imaging process, comprising:
- at least one non-transitory storage medium including a set of instructions;
- and
- at least one processor in communication with the at least one non-transitory storage medium, wherein when executing the set of instructions, the at least one processor is configured to direct the system to:
- obtain a current image generated based on an exposure parameter, wherein the current image includes a plurality of pixels;
- determine a plurality of target pixels or target pixel groups from at least portion of the plurality of pixels;
- determine a statistic representation based on the plurality of target pixels or the target pixel groups;
- determine a characteristic feature based on the statistic representation;
- and
- update the exposure parameter, based on the characteristic feature, to generate an updated image.
(canceled)
A non-transitory computer readable medium comprising executable instructions that, when executed by at least one processor, cause the at least one processor to effectuate a method comprising:
- obtaining a current image generated based on an exposure parameter, wherein the current image includes a plurality of pixels;
- determining a plurality of target pixels or target pixel groups from at least portion of the plurality of pixels;
- determining a statistic representation based on the plurality of target pixels or the target pixel groups;
- determining a characteristic feature based on the statistic representation;
- and
- updating the exposure parameter, based on the characteristic feature, to generate an updated image.
