UNIFIED ISP PIPELINE FOR IMAGE SENSORS WITH VARIOUS COLOR FILTER ARRAY AND HIGH DYNAMIC RANGE SCHEMES

Abstract:

An image processing method and an image processing device is provided. The processing device comprises memory and a processor configured to receive a frame of color filtered image data comprising pixels which are spatially multiplexed according to a plurality of different light exposures, resample the color values as different frames of pixels for the plurality of different light exposures, fuse the resampled frames of pixels for the plurality of different light exposures into a frame of pixels according to a HDR format and color interpolate the fused frame of pixels. The processor is configured to interpolate, for each resampled frame, missing pixel color values based on the color values of adjacent resampled pixels in a same resampled frame. The color interpolated fused frame of pixels is processed in an image processing pipeline and converted to a YUV color space.
