Abstract
Provided is an imaging device that can acquire three independent high-quality images using one imaging element. An imaging device includes: an optical system (10) including three optical regions (12A, 12B, 12C) that transmit light in different polarization directions; an imaging element (100) including a plurality of pixel units each of which is a set of three pixels that receive light in different polarization directions; and an image processing unit (200) that calculates three pixel signals (X1, X2, X3) corresponding to each of the optical regions (12A, 12B, 12C) of the optical system (10) from three pixel signals (x1, x2, x3) obtained from each pixel unit of the imaging element (100) to generate an image of each of the optical regions (12A, 12B, 12C).
Claims12
An imaging device comprising:
- an optical system including three optical regions that transmit light in different polarization directions, and configured to focus on objects at different distances;
- an imaging element including a plurality of pixel units each of which is a set of N pixels that receive light in different polarization directions, where N is an integer satisfying N≥3;
- a memory that stores a coefficient group configured by a matrix A of 3 rows and N columns in which each element is represented by aij, where i is an integer satisfying 1≤i≤3 and j is an integer satisfying 1≤j≤N;
- and
- a processor that acquires the coefficient group from the memory and calculates only three pixel signals X1, X2, and X3 corresponding to each of the optical regions of the optical system from N pixel signals x1, x2, . . . , xN obtained from each of the pixel units of the imaging element using the following expression
