Abstract:
1. A display-and-image-pickup apparatus comprising: a display-and-image-pickup panel having an image display function and an image pickup function; an image producing means for producing a predetermined processed image on the basis of a picked-up image of a proximity object obtained through the use of the display-and-image-pickup panel; an image processing means for obtaining information about at least one of position, shape and size of the proximity object through selectively using one of two obtaining modes on the basis of at least one of the picked-up image and the processed image; and a switching means for performing a switching process between the two obtaining modes in the image processing means on the basis of the magnitude of a predetermined parameter so that, in the case where the parameter is increasing, one of the two obtaining modes is switched to the other obtaining mode when the parameter reaches a first threshold value, and in the case where the parameter is decreasing, the other obtaining mode is switched to the one obtaining mode when the parameter reaches a second threshold value smaller than the first threshold value.
