Abstract

An image processing apparatus includes a blurring processing unit configured to generate a blurred image by applying a two-dimensional Gaussian filter having a filter size of S1×S2 to an input image, and a resolution conversion unit configured to generate, from the blurred image, a converted image of which a resolution is converted at a first conversion magnification R1 and a second conversion magnification R2. When the blurring processing unit sets a relation of S1>S2, a relation of R2>R1 is established, and when the blurring processing unit sets a relation of S2>S1, a relation of R1>R2 is established. Here, standard deviations of the Gaussian filter are set to be standard deviations σ1 and σ2, respectively. The blurring processing unit applies the Gaussian filter having a filter coefficient of σ2=σ1 to the input image when S2 is different from S1.
