Abstract: A processing device comprises a memory configured to store data and a processor. The processor is configured to control an exposure timing of a rolling shutter image sensor and an IR illumination timing of an object, by an IR light emitter, by switching between a first operation mode and a second operation mode. In the first operation mode, a sequence of video frames, each having a plurality of pixel lines, comprises a frame in which each pixel line is exposed to IR light emitted by the IR light emitter; a frame which is partially exposed to the IR light and a frame in which no pixel line is exposed to the IR light. In the second operation mode, alternating video frames of the sequence comprise one of a frame in which each pixel line is exposed to the IR light and a frame in which no pixel line is exposed to the IR light.

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.
