1. An image display apparatus that can execute calibration of display characteristics, comprising:
a plurality of light emitting units corresponding to a plurality of divided regions constituting a region of a screen; a display panel configured to display an image on the screen by transmitting light from the plurality of light emitting units at a transmittance based on input image data; a first acquisition unit configured to acquire brightness information of the input image data for each divided region; a first control unit configured to determine light emission quantity for each of the light emitting units on the basis of the brightness information of each divided region acquired by the first acquisition unit, and to allow each light emitting unit to emit light at the determined light emission quantity; a second acquisition unit configured to acquire, from a sensor, a detected value of light from a predetermined region of the screen; a first determination unit configured to determine whether a change due to a difference of the light emission quantity between the light emitting units is generated in the light from the predetermined region, on the basis of the light emission quantity of each light emitting unit determined by the first control unit; a calibration unit configured to perform the calibration using the detected value from the sensor; and a second control unit configured to control at least one of the sensor, the second acquisition unit and the calibration unit, so that the calibration, directly using the detected value acquired when the first determination unit has determined that the change is generated, is not performed. |
