Classification: CPC H  G | IPC G  H

Claim 26:
27. An apparatus, comprising:
an image sensor;
a memory storing processor-readable code; and
at least one processor coupled to the memory and to the image sensor, the at least one processor configured to execute the processor-readable code to cause the at least one processor to:
receiving an input image frame representing a scene at a first resolution, wherein the input image frame comprises first image data and second image data, the first image data corresponding to a first exposure time longer than a second exposure time of the second image data;
determining a first image frame from the first image data and the second image data, wherein the first image frame has a same resolution as the first resolution, wherein determining the first image frame comprises performing operations including:
determining compensated second image data by adjusting the second image data based on the first exposure time and the second exposure time;
forming a full-resolution long-exposure image frame in a first color pattern arrangement based on the first image data and the compensated second image data; and
converting the full-resolution long-exposure image frame from the first color pattern arrangement to a second color pattern arrangement to determine the first image frame;

determining a second image frame from the second image data, wherein the second image frame has a same resolution as the first resolution, wherein determining the second image frame comprises performing operations including:
forming a lower-resolution short-exposure image frame in a third color pattern arrangement based on the second image data;
converting the lower-resolution short-exposure image frame from the third color pattern arrangement to the second color pattern arrangement; and
upscaling the lower-resolution short-exposure image frame to a full-resolution short-exposure image frame, wherein the second image frame is the full-resolution short-exposure image frame; and

determining an output image frame based on the first image frame and the second image frame.
