IMAGE DISPLAY APPARATUS AND CONTROL METHOD THEREFOR

摘要

An image display apparatus includes a light-emitting unit, a display unit configured to modulate light from the light-emitting unit, a light-emission control unit configured to control light emission of the light-emitting unit, a display control unit configured to execute display processing for displaying images for calibration in order, an acquiring unit configured to acquire a measurement value of light emitted from a region, of a screen, where the image for calibration is displayed, and a calibrating unit configured to execute a calibration on the basis of measurement values of the images, wherein when a light emission state of the light-emitting unit changes during the execution of the display processing, the display control unit executes the display processing again.

1. An image display apparatus capable of executing calibration of at least one of brightness and a color of a screen, the image display apparatus comprising:
a light-emitting unit; a display unit configured to display an image on the screen by modulating light from the light-emitting unit; a light-emission control unit configured to control light emission of the light-emitting unit on the basis of input image data; a display control unit configured to execute display processing for displaying a plurality of images for calibration on the screen in order; an acquiring unit configured to execute, for each of the plurality of images for calibration, processing for acquiring a measurement value of light emitted from a region, of the screen, where the image for calibration is displayed; and a calibrating unit configured to execute the calibration on the basis of the measurement values of the plurality of images for calibration, wherein when a light emission state of the light-emitting unit changes during the execution of the di splay processing from a light emission state of the light-emitting unit before the execution of the display processing, the display control unit executes at least a part of the display processing again.
