Patent ID: 8619189

Claim:
An image processing apparatus to reduce an effect of an isolated noise in a process that converts a frame rate by dividing an input frame into sub-frames and outputting the sub-frames, the image processing apparatus comprising: a minimum value filter unit configured to acquire a pre-processed input frame from the input frame, wherein the minimum value filter unit obtains a set of minimum target values of a target pixel having an initial target pixel value in a processing target block of the input frame, selects one target value from the set of minimum target values, and replaces the initial target pixel value with the selected one target value to acquire the pre-processed input frame, wherein, in a case where a pixel value of an isolated noise is the minimum pixel value in the set of minimum target values, the minimum value filter unit does not select the isolated noise as the one target value from the set of minimum target values; a low-pass filter processing unit configured to perform low-pass filter processing on the pre-processed input frame and generate a first sub-frame; a generation unit configured to generate a second sub-frame from the first sub-frame and the input frame; and a switching unit configured to switch the first sub-frame and the second sub-frame at a predetermined timing and output a sub-frame.
