Abstract
In making a contact determination between an object and a display screen, a display apparatus of the present invention is capable of adjusting a region on which to make a contact determination in response to the displayed image in a liquid crystal panel, so that the influence by the displayed image can be suppressed. Moreover, for simplifying the contact determination process, the display apparatus sets solid a region in the picked-up image that is not a target of the contact determination, with a predetermined gradation value.
