  • 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: 9959814
    Abstract: Provided is a display device and display method that can improve the moving image display performance. A display device includes a display panel and a backlight for the display panel. The display device also includes control means configured to output a control signal for controlling illumination and extinction of the backlight, to the backlight in synchronization with start of update of a frame on the display panel and update means configured to update a frame in each predetermined period in order to change one image displayed on a screen of the display panel. The control means outputs a control signal for controlling the backlight so that the backlight starts to illuminate after the update means starts to update one frame and ends illumination at the time point when the update means starts to update a frame subsequent to the one frame or after the time point.
