Abstract
According to an aspect of the invention, a video display apparatus includes: a sensor that measures an external environment to output the external environment; a storing unit that stores a correction value associated with the measured value; a adjusting unit that changes the correction value based on a given operation by a user; and a processor that adjusts a picture quality of a picture to be displayed on a display based on the measured value and the correction value.
Claims7
A video display apparatus comprising:
- a sensor that measures an illuminance at the video display apparatus;
- a picture quality adjusting portion that, while displaying a relation between a plurality of illuminances and a plurality of picture quality adjusting set values and a currently-measured illuminance on a display portion as a graph, changes the picture quality adjusting set value correlated with a selected illuminance selected from the illuminances based on an operation of an operating portion, wherein the graph includes an axis of abscissa indicating the plurality of illuminances and an axis of ordinate indicating the plurality of picture quality adjusting set values;
- a storing portion that stores, connectedly with the selected illuminance, the picture quality adjusting set value changed by the picture quality adjusting portion;
- and
- a picture quality processing portion that adjusts a picture quality of an input video signal by acquiring, according to the currently-measured illuminance, the picture quality adjusting set value correlated with the currently-measured value from the storing portion.
