    Abstract: For a solid-state image pickup device 1, a plurality of pixels are two dimensionally arranged in an imaging region 10, and two photodiodes PD1 and PD2 are included in each pixel Pm,n. An electric charge generated in the respective photodiodes PD1 and PD2 is input to a signal readout section 20, and a voltage according to an electric charge amount thereof is output from the signal output section 20. The voltage output from the signal readout section 20 is input to an A/D converting section 40, and a digital value according to the input voltage is output from the A/D converting section 40. In an adding section 50, a sum of digital values to be output from the A/D converting section 40 according to the amount of electric charge generated, for each pixel Pm,n of the imaging region 10, in the two respective photodiodes PD1 and PD2 included in the pixel is operated, and a digital value being a sum value thereof is output.

    Abstract: The solid-state image pick-up device (1) includes a photodetecting section (10) which is formed by two-dimensionally aligning M×N (M and N are integers not less than 2) pixels in M rows and N columns and has a rectangular photodetecting surface. This solid-state image pick-up device (1) is supported rotatably by a rotation controlling section, and the rotation controlling section controls the rotation angle of the solid-state image pick-up device (1) so that the row direction or column direction of the photodetecting section (10) becomes parallel to the movement direction (B) of the solid-state image pick-up device (1) in one of the two imaging modes, and both of the row direction and the column direction of the photodetecting section (10) tilt with respect to the movement direction (B) of the solid-state image pick-up device (1) in the other imaging mode of the two imaging modes.

The metal wire 14 is provided so that its edge covers pn junction portions (interfaces between p?-type layer 12c and n+-type semiconductor regions 12d) exposed on a light-incident surface of the semiconductor substrate 12 (p?-type layer 12c), above the pn junction portions, and is of grid shape. The metal wire 14 is grounded and the isolation region 12e is set at the ground potential.

  • Patent number: 7041982
    Abstract: A solid-state imaging device and a frame are secured onto a base plate. The frame has a positioning portion in contact with a side face of a substrate, so as to protect the bonding wire positioned thereunder while positioning and supporting the substrate abutting thereagainst. The frame is made of a metal, and is further provided with a shield member, so as to restrain X-rays from entering a bonding wire and the like. The substrate is set relatively thin, whereby its X-ray transmissivity improves, though substrate bent occurs in this case. Since an elastic body presses the substrate, the bent of the substrate is corrected.
