Abstract: A depth image engine and a depth image calculation method are provided. The depth image engine comprises: a buffer, configured to receive a data flow of a first image; an image rotator, configured to perform, after the buffer receives the entire data flow of the first image, a rotation operation on the first image to generate a second image; and a depth value calculator, configured to receive the second image and a reference image to perform a matching calculation on the second image and the reference image to generate a depth image.

Abstract: A depth calculation processor includes: an input port, configured to receive image data from an image sensor; a demultiplexer, connected to the input port, and configured to demultiplex the image data from the input port and output first image data into a first line and second image data into a second line; a grayscale image engine, configured to process the first image data from the first line to generate processed first image data; a depth image engine, configured to receive the second image data from the second line, and calculate depth image data based on the second image data; a multiplexer, configured to output the processed first image data from the grayscale image engine and the depth image data from the depth image engine; and an output port, configured to output the processed first image data and the depth image data from the multiplexer.
