Abstract
A portable terminal apparatus provided with an image processing function permitting automatic image-pickup without manual focusing which includes an optical system for forming an optical image of a surface of a subject, a two-dimensional photoelectric conversion element for performing photoelectric conversion onto the formed optical image, a signal conversion device for converting an output signal of the photoelectric conversion element into a digital signal, a memory device for temporarily storing the two-dimensional image signal digitized by the signal conversion device, a subject position detecting device storing the optimum image-formation distance of the optical system in advance and for detecting the distance between the subject and the optical system, and an image inputting device including an electronic shutter device which supplies a video signal on the two-dimensional photoelectric conversion element to the memory device to hold the video signal in the memory device instantaneously when the subject position detecting device detects that the subject is located at an image-forming distance.
