Image processing apparatus to reduce isolated noise effects in moving image drive distribution processing
Abstract:
An image processing apparatus, which converts a frame rate by dividing an input frame into sub-frames and outputting the sub-frames, includes a minimum value filter unit, a low-pass filter processing unit, a generation unit, and a switching unit. In an input frame, the minimum value filter unit selects a maximum value of minimum values from the minimum values of pixel values in each horizontal line in a predetermined area including peripheral pixels of a processing target pixel, and performs pre-processing to replace the processing target pixel with the maximum value. The low-pass filter processing unit performs low-pass filter processing on the pre-processed input frame and generates a first sub-frame. The generation unit generates a second sub-frame from the first sub-frame and the input frame. The switching unit switches the first sub-frame and the second sub-frame at predetermined timing and outputs a sub-frame.
