Display apparatus and control method thereof

摘要

A display apparatus according to the present invention includes: a measuring unit that measures an image displayed on a screen; a first determining unit that determines a first display setting by executing a single unit calibration; a second determining unit that determines a second display setting by executing a link calibration; and a determining unit that determines, during display of an external input image, which is an image based on an image signal input from an external apparatus, whether or not an output setting of the external apparatus or the second display setting differs from a setting during display of a previous external input image. The second determining unit executes the link calibration when the determining unit determines that the output setting of the external apparatus or the second display setting differs from the setting during display of the previous external input image.

1. A display apparatus comprising:
a measuring unit that measures an image displayed on a screen; a first determining unit that determines a first display setting by executing a single unit calibration in which a pre-stored first calibration image is displayed and a display setting is adjusted such that a measurement value of the first calibration image measured by the measuring unit approaches a target value; a second determining unit that determines a second display setting by executing a link calibration in which a second calibration image based on a calibration image signal input from an external apparatus is displayed and the display setting is adjusted such that a measurement value of the second calibration image measured by the measuring unit approaches the target value; and a third determining unit that executes, in a case where an external input image, which is an image based on an image signal input from the external apparatus, is displayed, a determination whether or not an output setting of the external apparatus or a second display setting differs from a setting during display of a previous external input image which is an image based on a previous external input image signal, wherein in a case where the external input image is displayed, the second calibration image is displayed at a second display setting, the third determining unit determines that the output setting of the external apparatus or the second display setting differs from the setting during display of the previous external input image in a case where a difference between the measurement value of the second calibration image measured by the measuring unit and the target value is greater than a predetermined threshold, and the second determining unit executes the link calibration in a case where the third determining unit determines that the output setting of the external apparatus or the second display setting differs from the setting during display of the previous external input image.
