Abstract
In example implementations, an apparatus is provided. The apparatus includes a video camera to capture an image of a participant on a video call, an ambient light sensor to detect light, and a processor communicatively coupled to the video camera, the memory, and the ambient light sensor. The processor is to identify a portion of a video image of the video call that includes the image of the participant, detect a type of light on the participant based on the light detected by the ambient light sensor, and perform a light compensation to match a color range of the image of the participant and a color range of a background image selected for the video call based on the type of light that is detected.
Claims20
An apparatus comprising:
- an image sensor;
- a processor in communication with the image sensor, wherein the processor is to:
- receive, from the image sensor, an image;
- identify a first region of the image and a second region of the image;
- detect a light source or a shadow associated with the first region of the image;
- and
- perform light compensation on the second region of the image or a virtual background associated with the second region of the image, based on the detected light source or the shadow of the first region.
A method comprising:
- detect a type of light source on an image;
- divide the image into a first region having the first type of light source and a second region;
- apply a light compensation on a virtual background, based on the first type of light source;
- and
- generate an updated image that includes the second region and the virtual background in place of the first region.
A non-transitory computer readable storage medium encoded with instructions which, when executed, cause a processor of an apparatus to:
- receive an image having a first region and a second region;
- identify a light source in the first region of the image;
- apply a light compensation on the second region or a virtual background associated with the second region, wherein the light compensation is based on the light source in the first region;
- and
- generate an updated image that includes the first region and the compensated second region or the compensated virtual background.
