摘要： 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.

摘要： A solid-state image sensor according to the present invention includes a number of photosensitive cells 2b, 2c that are arranged in between the first surface 30a of a semiconductor layer 30 and its second surface 30b, which is opposite to the first surface 30a and which receives incoming light. As viewed from the photosensitive cells 2b, 2c, a reflecting portion 3a is arranged on the same side as the first surface 30a in order to reflect an infrared ray that has been transmitted through the photosensitive cell 2c and make it incident on one of the photosensitive cells 2b, 2c. As a result, the intensities of infrared rays to be converted photoelectrically by the photosensitive cells 2b, 2c will be different from each other. And by calculating the difference between the photoelectrically converted signals supplied from the photosensitive cells 2b, 2c, the infrared ray component received by each photosensitive cell can be obtained. In addition, by arranging a color filter 1b on the same side as the second surface 30b, an infrared ray component and a color component can be obtained at the same time.

摘要： A mirror 1a transmits a cyan (Cy) ray and reflects an R ray, and a mirror 1d transmits a yellow (Ye) ray and reflects a B ray. The mirrors 1a and 1d are arranged inside a light-transmitting member 3 and are also tilted so that the light reflected from each of them is further reflected from the interface between the light-transmitting member 3 and the air and then incident on an adjacent photosensitive cell. Photosensitive cells 2a and 2d receive the light rays that have been transmitted through the mirrors 1a and 1d, respectively. No mirrors are arranged over photosensitive cells 2b and 2c. The photosensitive cell 2b receives directly incident light and the light ray reflected from the mirror 1a. The photosensitive cell 2c receives the directly incident light and the light ray reflected from the mirror 1d. Color information is obtained by making computations on the output signals of the respective photosensitive cells.

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.
