<p>A light-receiving sensor comprising a semiconductor device, e.g. a CCD or a C-MOS, and an electronic digital camera comprising the light-receiving sensor. The light receiving sensor has a light-receiving surface of a concave spherical focusing cross-section (2), and a diaphragm (3) is disposed the central position in the thickness of a superwide-angle aspherical single lens (1). Excellent focusing characteristics are provided up to a superwide angle and an image can be observed with high resolution and high optical characteristics.</p> |
