A solid-state imaging device according to the present invention includes, on an imaging surface, a plurality of unit pixel regions being arrayed at a first pixel pitch along a Y direction and at a second pixel pitch along an X direction. One of two adjoining unit pixel regions 1 along the Y first direction includes a first photodetecting portion 1a having a first opening ratio, and the other includes a second photodetecting portion 1b having a second opening ratio which is lower than the first opening ratio. When the first photodetecting portion 1a is moved imaginarily by a first pixel pitch along the Y direction, the first photodetecting portion 1a covers the entire second photodetecting portion 1b. At this time, a portion of the first photodetecting portion 1a that does not cover the second photodetecting portion 1b functions as an imaginary third photodetecting portion. From a difference between signals output from the photodetecting portions 1a and 1b, an imaginary pixel signal which is in accordance with an amount of light entering the imaginary third photodetecting portion is obtained.

摘要:
A color representation technique to be effectively applicable to a pixel shifted arrangement to realize high sensitivity and high resolution is provided by using a dipersive prism or diffraction.A dispersive element is provided for an image sensor in which photosensitive cells are arranged to be shifted from each other by a half pitch both horizontally and vertically. The dispersive element makes at least G rays fall straight down to a pixel right under itself and also makes either R rays or B rays incident on an adjacent pixel. Meanwhile, a photosensitive cell, for which no dispersive element is provided, receives directly incident light, too. Color information can be obtained by making computations on photoelectrically converted signals provided by these pixels.

The solid-state image sensor 10 includes an array of photosensitive cells and an array 100 of dispersing elements. The photosensitive cell array is comprised of unit blocks 40, each including four photosensitive cells 2a, 2b, 2c and 2d.

Light-splitting elements are arranged in at least two columns and two rows to form two pairs 1a, 1b and 1c, 1d. Each element splits incident light into light rays and makes them fall on a portion of a photosensing section right under itself and an adjacent photosensitive cell. The element 1a splits the incident light so that a primary color ray C1 and its complementary color ray C1′ enter an adjacent cell 2b and an underlying cell 2a, respectively. The element 1b makes a primary color ray C2 and its complementary color ray C2′ enter an underlying cell 2a and an adjacent cell 2a, respectively. The element 1c does the same as the element 1b. And the element 1d makes a primary color ray C3 and its complementary color ray C3′ enter an adjacent cell 2c and an underlying cell 2d, respectively. These photosensitive cells 2 perform photoelectric conversion, thereby outputting an electrical signal representing the intensity of the incident light. By carrying out simple calculations between the outputs of these cells, a color signal and a luminance signal are generated.
