Abstract
A semiconductor device includes a hash generator, a reference hash list, a frame mode determination unit, and an intra prediction unit. The hash generator generates a hash value of a target frame to be encoded. The reference hash list is to record the hash value generated by the hash generator. The frame mode determination unit compares the hash value generated by the hash generator and the hash value in the reference hash list. The intra prediction unit performs intra prediction for the target frame to be encoded. When the hash value of the target frame to be encoded coincides with any of the hash values in the reference hash list, the intra prediction unit skips an encoding process, and outputs encoded information corresponding to any of the hash values in the reference hash list.
