1. A depth calculation processor, comprising:
an input port, configured to receive image data from an image sensor;
a depth image engine, configured to receive the image data from the input port, and calculate depth image data; and
an output port, configured to receive and output the depth image data, wherein
the depth image engine comprises:
a buffer, configured to receive the image data;
an image rotator, configured to perform, after the buffer receives the entire image data, a rotation operation on the image data to generate a rotated image; and
a depth value calculator, configured to receive the rotated image and a reference image to perform a matching calculation to generate the depth image data.
