IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND STORAGE MEDIUM

摘要

An image processing apparatus includes a selection unit, a pixel number setting unit, a determination unit, and a processing unit. The selection unit selects at least a pixel that is different from a pixel of interest in an image based on a similarity between a pixel value of the pixel different from the interest pixel and a pixel value of the interest pixel. The pixel number setting unit sets a number of pixels to be selected. The determination unit determines, from a pixel selected by the selection unit and based on whether a number of selected pixels has reached the set number of pixels, at least a pixel to be used in predetermined processing. The processing unit performs the predetermined processing on the interest pixel using a pixel value of the pixel determined by the determination unit.

1. An image processing apparatus comprising:
a selection unit configured to select at least a pixel that is different from a pixel of interest in an image based on a similarity between a pixel value of the pixel different from the pixel of interest and a pixel value of the pixel of interest; a pixel number setting unit configured to set a number of pixels to be selected by the selection unit; a determination unit configured to determine, from a pixel selected by the selection unit and based on whether a number of pixels selected by the selection unit has reached the number of pixels set by the pixel number setting unit, at least a pixel to be used in predetermined processing; and a processing unit configured to perform the predetermined processing on the pixel of interest using at least a pixel value of a pixel different from the pixel of interest, wherein the processing unit performs the predetermined processing on the pixel of interest using a pixel value of the pixel determined by the determination unit.
