High dynamic range (hdr) data conversion and color space mapping

A data conversion and color-space mapping (DCM) circuit, comprising:

• a processing system;
• and
• a memory storing instructions that, when executed by the processing system, causes the DCM circuit to:
• receive image data for one or more frames acquired by an image capture device;
• transfer the image data from a non-linear domain to a linear domain using an inverse opto-electrical transfer function (IOETF);
• convert the linear image data from a first color space to a second color space, wherein each of the first and second color spaces is based on a gamut of the image capture device;
• and
• process the image data to be rendered on a display device by remapping the converted image data from the second color space to a third color space, wherein the third color space is based on a gamut of the display device.

A system comprising:

• a display device configured to display one or more frames acquired by an image capture device;
• and
• a data conversion and color-space mapping (DCM) circuit configured to:
• receive image data for the one or more frames;
• transfer the received image data from a non-linear domain to a linear domain using an inverse opto-electrical transfer function (IOETF);
• convert the linear image data from a first color space to a second color space, wherein the first and second color spaces are based on a gamut of the image capture device;
• and
• remap the converted image data from the second color space to a third color space, wherein the third color space is based on a gamut of the display device.
