IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND STORAGE MEDIUM

摘要

In an image processing apparatus for processing image data to be input, an edge image of which a pixel value changes between pixels is extracted from a generated drawing image of each color. Further, processing for expanding an edge amount is performed with respect to the extracted edge image, and brightness of a pixel of the drawing image corresponding to a pixel of the expanded edge image is adjusted based on the extracted edge amount.

1. An image processing apparatus for processing image data to be input, the image processing apparatus comprising:
a generation unit configured to generate a drawing image of each color from the image data; an extraction unit configured to extract an edge image of which a pixel value changes between pixels from the generated drawing image of each color; an edge amount expansion unit configured to perform processing for expanding an edge amount with respect to the extracted edge image; and a processing unit configured to adjust brightness of a pixel of the drawing image corresponding to a pixel of the expanded edge image based on the edge amount.
