  • Patent number: 11776114
    Abstract: An object of the present invention is to provide an information processing method and a computer program that can suppress an increase in inspection time in the manufacturing process of the monitors. The present invention provides an information processing method comprising: an error calculation step of calculating an error between input image data input to an autoencoder and output image data output from the autoencoder; a similarity calculation step of calculating a similarity between compressed data and reference data based on the compressed data and the reference data, the compressed data being acquired by compressing the input image data in an encoder of the autoencoder; and a determination step of determining whether a display unevenness of the input image data is acceptable based on a relationship between the error and the similarity, the relationship corresponding to a relational expression or a table.

  • Patent number: 11276367
    Abstract: According to an aspect of the present invention, provided is an image processing device comprising a saturation value acquisition unit configured to acquire a saturation value of a target pixel or a saturation value of a target small area including a target pixel and peripheral pixels around the target pixel, and a correction unit configured to correct the target pixel so that a corrected gradation characteristic obtained by correcting the target pixel matches a gradation characteristic synthesized by mixing a color gradation characteristic and a monochrome gradation characteristic at a predetermined mixing ratio based on the saturation value, wherein assuming that the saturation value is c, and the mixing ratio of the color gradation characteristic is W, a value of W is represented by variable c as a relationship W=f(c) and satisfies a following condition.
