Abstract
This image quality evaluation device comprises: a conversion unit that converts the data of an image to two-dimensional array data of the luminance value of each pixel in the image; a processing unit that executes an averaging process, based on a plurality of filter sizes, on each pixel of the two-dimensional array data; and an evaluation unit that evaluates the quality of the image using the processing results of the processing unit.
Claims10
An image forming apparatus, comprising:
- an image forming section that forms an image on a recording medium;
- a first hardware processor that controls the image forming section based on a predetermined image forming condition;
- and
- an image quality evaluation apparatus, including:
- a second hardware processor that acquires image data of the image, wherein
- the second hardware processor
- converts the image data into two-dimensional array data of a luminance value of each pixel of the image,
- performs average processing based on a plurality of filter sizes for each pixel of the two-dimensional array data, and
- performs evaluation of image quality of the image by using a result of the average processing.
