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： The 3D image capture device includes a light-transmitting section with n transmitting areas (where n is an integer and n≧2) that have different transmission wavelength ranges and each of which transmits a light ray falling within a first wavelength range, a solid-state image sensor that includes a photosensitive cell array having a number of unit blocks, and a signal processing section that processes the output signal of the image sensor. Each unit block includes n photosensitive cells including a first photosensitive cell that outputs a signal representing the quantity of the light ray falling within the first wavelength range. The signal processing section generates at least two image data with parallax by using a signal obtained by multiplying a signal supplied from the first photosensitive cell by a first coefficient, which is real number that is equal to or greater than zero but less than one.
