Image processing apparatus capable of writing compressed data into frame buffer and reading buffered data from frame buffer alternately and related image processing method thereof

Abstract

An image processing apparatus includes a processing circuit and a storage system. The processing circuit generates a first processing result and a second processing result by processing a first horizontal line group of a first frame and a second horizontal line group of a second frame preceding the first frame, respectively. The storage system includes: a frame buffer; a write circuit for storing the first processing result into the frame buffer; a read circuit for reading the second processing result from the frame buffer; and a timing controller for controlling the write circuit to start storing the first processing result at a first time point not prior to a specific time point when the processing circuit finishes receiving the first horizontal line group, and controlling the read circuit to start reading the second processing result at a second time point which is prior to the specific time point.
