Abstract
In some examples, an electronic device includes a processor to detect a saturated highlight of a video frame. In response to the detection, the processor is to identify an area of the saturated highlight and adjust an exposure of an image sensor for the area of the saturated highlight.
Claims20
An electronic device, comprising:
- a processor to:
- detect a saturated highlight of a video frame, wherein the saturated highlight is a pixel of the video frame that has a largest tonal value of a range of tonal values;
- in response to the detection, determine whether the saturated highlight is stationary:
- in response to a determination that the saturated highlight is stationary, identify an area of the saturated highlight;
- and
- adjust an exposure of an image sensor for the area of the saturated highlight.

An electronic device, comprising:
- a processor to:
- detect an artifact of an image, wherein the artifact is an area of the image that has a largest or smallest value of a range of tonal values;
- in response to the detection, determine whether the artifact is stationary;
- in response to a determination that the artifact is stationary, identify an object within the artifact of the image;
- in response to determining that the object satisfies a criterion, identify an area of the artifact using the object;
- and
- adjust an exposure of an image sensor for the area of the artifact.
4 more elements
A non-transitory machine-readable medium storing machine-readable instructions which, when executed by a processor, cause the processor to:
- monitor a video signal for a frame that includes a saturated highlight, wherein the saturated highlight is an area of the frame that has a largest value of a range of tonal values, the video signal received from an image sensor;
- in response to receiving the frame that includes the saturated highlight, determine whether the saturated highlight is stationary;
- in response to a determination that the saturated highlight is stationary, determine an area of the saturated highlight;
- and
- adjust an exposure of the image sensor for the area of the saturated highlight.
