Abstract
An image processing apparatus including first circuitry, second circuitry, third circuitry, and fourth circuitry is provided. The first circuitry determines a frame miss rate according to a current frame rate and a target frame rate of an image signal. The second circuitry decreases the target frame rate to the current frame rate when the frame miss rate is greater than a first threshold. The third circuitry increases the target frame rate to an upper-limit frame rate which is determined according to the frame rendering time or memory bandwidth capability, when the frame miss rate is less than a second threshold which is smaller than the first threshold. The fourth circuitry applies the decreased or increased target frame rate for an image to be displayed.
