Abstract
A display apparatus includes a light source, a light amount control unit configured to control an amount of light emitted from the light source, an image processing unit configured to control a signal level of the image signal, and a control unit configured to control the light amount control unit and the image processing unit based on the image signal. The control unit performs control such that, when the image signal changes, the signal level of the image signal controlled by the image processing unit becomes a signal level corresponding to the changed image signal more quickly than the light amount controlled by the light amount control unit reaches a light amount corresponding to the changed image signal.
