Patent ID: 8421917

Claim:
An image processing apparatus configured to output moving image data which is input at m frames per unit time as output moving image data at N×m (N>2) frames per unit time, comprising: a filter unit configured to separate image data from an input frame of interest into spatial high-frequency component image data and spatial low-frequency component image data; a storage unit configured to store the spatial high-frequency and spatial low-frequency component image data obtained by said filter unit; a read unit configured to read the spatial high-frequency component image data and the spatial low-frequency component image data from said storage unit N times; a multiplication unit configured to , multiply the spatial high-frequency component image data and the spatial low-frequency component image data by predetermined multiplier coefficients which are set to make a temporal center of gravity of the spatial high-frequency component image data match that of the spatial low-frequency component image data and make temporal distribution of the spatial high-frequency component image data smaller than that of the spatial low-frequency component image data; an addition unit configured to add the spatial high-frequency component image data and the spatial low-frequency component image data after multiplication by said multiplication unit every time the data is read; and an output unit configured to output the summed image data from said addition unit.
