Abstract:
1. A position detecting method for detecting at least a position of an object executed by a display apparatus including a panel part having a plurality of light emission cells which display an image on a display surface and emit detection light, and a plurality of light reception cells which receive the detection light incident from a side of the display surface; the method comprising: storing initial data and detection data; generating an image with an image generating unit on the basis of a first light reception image and a second light reception image, the first light reception image being obtained from the plurality of light reception cells in a first period in which the detection light is emitted from the display surface, and the second light reception image being obtained from the plurality of light reception cells in a second period in which the detection light is not emitted from the display surface; determining, by an image determining unit whether or not an image of a detected object is included in the image, storing data corresponding to the image as the initial data into a storage unit when it is determined that there is no detected object included in the image, and storing data corresponding to the image as the detection data into the storage unit when it is determined that a detected object is included in the image; and determining a position of the detected object based on the stored initial data and detected data.
