Abstract
A solid-state imaging device according to an embodiment includes: an imaging element including an imaging area formed with a plurality of pixel blocks each including pixels; a first optical system forming an image of an object on an imaging surface; and a second optical system re-forming the image, which has been formed on the imaging surface, on the pixel blocks corresponding to microlenses, the second optical system including a microlens array formed with the microlenses provided in accordance with the pixel blocks. The microlenses are arranged in such a manner that an angle θ between a straight line connecting center points of adjacent microlenses and one of a row direction and a column direction in which the pixels are aligned is expressed as follows: θ>sin−1(2dp/Dml), where Dml represents microlens pitch, and dp represents pixel pitch.
