IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD |
摘要 |
In order to suitably perform image processing for enhancing edge reproducibility on an image, an image processing apparatus, determines whether or not a pixel of interest in an input image is a pixel configuring an edge, and determines whether or not the pixel of interest in the input image is a pixel configuring a semi-transparent object. In addition, the apparatus performs image processing for enhancing edge reproducibility for the pixel of interest if it is determined that the pixel of interest is a pixel configuring an edge and is not a pixel configuring a semi-transparent object. On the other hand, the apparatus inhibits execution of the image processing for the pixel of interest if it is determined that the pixel of interest is a pixel configuring an edge and is a pixel configuring a semi-transparent object. |

1. An image processing apparatus, comprising:
a first determination unit configured to determine whether or not a pixel of interest in an input image is a pixel configuring an edge; a second determination unit configured to determine whether or not the pixel of interest in the input image is a pixel configuring a semi-transparent object; and a first image processing unit configured to perform first image processing for enhancing edge reproducibility for the pixel of interest if it is determined that the pixel of interest is a pixel configuring an edge and is not a pixel configuring a semi-transparent object, and configured to inhibit execution of the first image processing for the pixel of interest if it is determined that the pixel of interest is a pixel configuring an edge and is a pixel configuring a semi-transparent object. |
