Abstract

A display correction apparatus includes one or more memories storing instructions and one or more processors configured to execute the instructions to: acquire an image obtained by imaging a display device in a state where first data based on original data of display content is displayed; specify a difference between a region of the image where the display device is imaged and the original data; generate second data by correcting the first data in such a way as to eliminate the difference; and display the second data on the display device.

13 . The display correction apparatus according to claim 12 , wherein the predetermined region is a region determined to be important in the display content.
14 . The display correction apparatus according to claim 10 , wherein the one or more processors are further configured to execute the instructions to: detect an illuminance of the display device; and acquire the image, in a case where a change in the illuminance is detected.
15 . The display correction apparatus according to claim 1 , wherein the one or more processors are configured to execute the instructions to: in a case where the difference is equal to or less than a predetermined value, determine not to perform correction.
16 . The display correction apparatus according to claim 1 , wherein the one or more processors are further configured to execute the instructions to: detect vibration of the display device; and in a case where the vibration is detected, acquire the image.
17 . A display correction method comprising: acquiring an image obtained by imaging a display device in a state where first data based on original data of display content is displayed; specifying a difference between a region of the captured image where the display device is imaged and the original data; generating second data by correcting the first data in such a way as to eliminate the difference; and displaying the second data on the display device.
18 . A non-transitory recording medium storing program for causing a computer to execute processing comprising: acquiring an image obtained by imaging a display device in a state where first data based on original data of display content is displayed; specifying a difference between a region of the captured image where the display device is imaged and the original data; generating second data by correcting the first data in such a way as to eliminate the difference; and displaying the second data on the display device.

Description

This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2024-168031, filed on Sep. 27, 2024, the disclosure of which is incorporated herein in its entirety by reference. TECHNICAL FIELD The present disclosure relates to a display correction apparatus, a display correction method, and a recording medium. BACKGROUND ART In order to display various types of content such as advertisements or guide signs, there is a technology for displaying data indicating the content on a display device such as a liquid crystal display or an electronic paper. In a case where data is displayed on the display device, there is a case where there is a difference between the data to be displayed and data actually displayed on the display device. To eliminate such a difference, the display may be adjusted. JP 2018-054763 A describes a technique for causing another image projection apparatus to project an image for adjustment used for adjustment in multi-screen display performed using a plurality of image projection apparatuses. SUMMARY An example of objects of the present disclosure is to facilitate bringing display using a display device closer to originally assumed display. A display correction apparatus according to one aspect of the present disclosure includes image acquisition means for acquiring an image obtained by imaging a display device in a state where first data based on original data of display content is displayed, specification means for specifying a difference between a region of the image where the display device is imaged and the original data, correction means for generating second data by correcting the first data in such a way as to eliminate the difference, and display control means for displaying the second data on the display device. A display correction method according to one aspect of the present disclosure includes acquiring an image obtained by imaging a display device in a state where first data based on original data of display content is displayed, specifying a difference between a region of the captured image where the display device is imaged and the original data, generating second data by correcting the first data in such a way as to eliminate the difference, and displaying the second data on the display device.
