Patent ID: 8588473

Claim:
An image processing apparatus to reduce flickers and blurs in moving image data and still image data, the image processing apparatus comprising: a conversion unit configured to store an input frame in a frame memory and read the input frame a plurality of times to convert the input frame into a twice-written input frame having a converted frame rate; a generation unit configured to receive the input frame from the conversion unit generate frames different from each other in frequency component; a detection unit configured to determine whether the input frame is a moving image or a still image by comparing the input frame with a frame immediately before or after the input frame in terms of time; a switching unit configured to multiple the twice-written input frame by a twice-written distribution ratio to generate a multiplied twice-written input frame, and output frames at predetermined timings, wherein, in response to the detection unit determining that the input frame is a still image, the switching unit refrains from outputting the frames different from each other in frequency component and outputs the multiplied twice-written input frame at each predetermined timing and, in response to the detection unit determining that the input frame is a moving image, the switching unit refrains from outputting the multiplied twice-written input frame and outputs a frame different from other frames in frequency component at each predetermined timing; and a central processing unit, wherein the central processing unit implements at least one of the conversion unit, the generation unit, the detection unit, and the switching unit.
