PROBLEM TO BE SOLVED: To confirm whether a display is displayed with a display as imaged at low cost.SOLUTION: According to a display confirmation method of a display device of the present invention, an application possessed by a control unit that outputs display data generates specific video information, and outputs the specific video information to a pixel conversion circuit via a graphic driver, and directly confirms and requests a pixel conversion circuit (scaler of FW) as to whether or not a correct display can be made in a display panel by paying attention to the specific pixel corresponding to the specific video information. The pixel conversion circuit transmits a response for the confirmation and the request to the control unit. The display confirmation application determines whether or not a correct display can be made by paying attention to the specific pixel corresponding to the specific video information. Thereby, it is possible to confirm whether the display is made on the display as imaged at a low cost without using a sensor of camera system which causes a rise in cost.SELECTED DRAWING: Figure 5 |
