<P>PROBLEM TO BE SOLVED: To provide a display and the like that detects ambient light with a high degree of accuracy. <P>SOLUTION: The display apparatus 10 includes a photo-sensor 30 for detecting the ambient light and outputting a photocurrent according to the intensity of the ambient light, wherein the display apparatus 10 includes a current sampling unit 32 and a light detection control unit 34. The current sampling unit is configured to sample the photocurrent output from the photo-sensor 30 and to output sampling signals to indicate the magnitude of the photocurrent. The light detection control unit is configured to determine an average of the sampling signals output from the current sampling unit 32 within a predetermined period of time. The current sampling unit 32 starts a next sampling period corresponding to the end of one of the sampling signals. <P>COPYRIGHT: (C)2011,JPO&INPIT |
