Abstract: A post processing apparatus includes a super-resolution (SR) filtering circuit and a loop restoration (LR) filtering circuit. The SR filtering circuit applies SR filtering to a processing result of a preceding circuit. The LR filtering circuit applies LR filtering to a processing result of the SR filtering circuit. Before the SR filtering circuit finishes SR filtering of all pixels of a frame that are generated by the preceding circuit, the LR filtering circuit starts LR filtering of pixels that are derived from applying SR filtering to pixels included in the frame.
