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.

Abstract: A method and apparatus for foreground detection by designating one of two non-occlusion areas as the foreground area according to results of position matching using two given motion vectors. The detection is performed by matching the position of the current occlusion area in the current frame with one or more positions of a previous occlusion area in a previous frame. The matching operation is based on motion vectors determined for the neighboring areas adjacent to the current occlusion area. The determination of the motion vectors are based on two neighboring frames temporally located before and after the current frame. If the position of the current occlusion area is matched with the previous occlusion area by using one of the motion vectors, the neighboring area corresponding to the motion vector is designated as a foreground area.

Abstract: The invention provides an ESD (Electrostatic Discharge) protection circuit including a clamp circuit, a switch element, and a detection circuit. The clamp circuit is coupled between an ESD bus and a ground node. The switch element is coupled between a supply node and the ESD bus. The detection circuit is configured to detect whether an ESD event occurs. When no ESD event occurs, the detection circuit closes the switch element, such that the ESD bus is coupled to the supply node. When the ESD event occurs, the detection circuit opens the switch element, such that the ESD bus is decoupled from the supply node.
