Abstract
An imaging system comprises a camera and one or more processors. The one or more processors are to process a plurality of channels associated with color information in a color space of an image captured by the camera to generate a second plurality of channels associated with corrected color information in a corrected color space. The one or more processors are further to determine a plurality of luminance values based at least in part on the second plurality of channels and an exposure value of the camera, and generate an updated version of the image using the plurality of luminance values.
Claims20
An imaging system, comprising:
- a camera;
- and
- one or more processors to:
- process a plurality of channels associated with color information in a color space of an image captured by the camera to generate a second plurality of channels associated with corrected color information in a corrected color space;
- determine a plurality of luminance values based at least in part on the second plurality of channels and an exposure value of the camera;
- and
- generate an updated version of the image using the plurality of luminance values.
A system comprising:
- a camera operatively coupled to an image signal processing (ISP) pipeline;
- and
- one or more processors associated with the ISP pipeline to:
- generate a plurality of luminance values based at least in part on a plurality of color channels of an image captured by the camera;
- adjust the plurality of luminance values based at least in part on a luminance calibration factor of the camera to obtain a plurality of calibrated luminance values;
- and
- generate an updated image based at least in part on the plurality of calibrated luminance values.
A system comprising:
- a memory;
- and
- one or more processors operatively connected to the memory, the one or more processors to:
- generate a plurality of luminance values based at least in part on a plurality of color channels of an image captured by a camera;
- adjust the plurality of luminance values based at least in part on an exposure value of the camera when the image was captured and a reference exposure value to obtain a plurality of normalized luminance values;
- and
- generate an updated image based at least in part on the plurality of normalized luminance values.
