Abstract:
Provided is a display apparatus including: a light emitting unit having a light source; a display unit configured to display an image by controlling a transmittance of light from the light emitting unit; first and second sensors provided in the light emitting unit to detect a brightness of the light source; and a control unit configured to control a transmittance of the display unit on the basis of detection values from the first and second sensors. A distance from the light source to the second sensor is longer than a distance from the light source to the first sensor. The control unit controls the transmittance of the display unit on the basis of a change degree of the detection value from the first sensor during a given period and a change degree of the detection value from the second sensor during the period.
