Image pickup device and rangefinder device

摘要

An imaging apparatus according to the present invention includes a lens optical system L, an imaging device N at least having a plurality of first and second pixels P1 and P2, an array optical device K, and a signal processing section C for generating an image. The lens optical system L has an optical region D1 and an optical region D2; the array optical device K causes light passing through the optical regions D1 and D2 to respective enter the plurality of first and second pixels P1 and P2; and a proportion of an amount of light exiting the optical region D2 relative to an amount of light entering the optical region D2 is smaller than a proportion of an amount of light exiting the optical region D1 relative to an amount of light entering the optical region D1.

主权项

1. An imaging apparatus comprising:
a lens optical system having a lens and a stop; an imaging device at least including a plurality of first pixels and a plurality of second pixels on which light passing through the lens optical system is incident; an array optical device disposed between the lens optical system and the imaging device, the array optical device including a plurality of optical elements; and a signal processing section for generating an image by using a plurality of pixel values obtained at the plurality of first pixels and a plurality of pixel values obtained at the plurality of second pixels, wherein, the lens optical system is divided into two regions that have a first region and a second region in the stop or in a plane substantially perpendicular to an optical axis and near the stop; the array optical element is a lenticular lens in which the plurality of optical elements that are elongated along a lateral direction are disposed in a vertical direction, each of the plurality of optical elements being arranged so as to correspond to two rows of pixels that includes one row of the plurality of first pixels and one row of the plurality of second pixels; the array optical device causes light passing through the first region to enter the plurality of first pixels, and causes light passing through the second region to enter the plurality of second pixels; the first region and the second region have substantial equal area, a proportion of an amount of light entering the first region relative to an amount of light exiting the first region being substantially uniform within the first region, and a proportion of an amount of light entering the second region relative to an amount of light exiting the second region being substantially uniform within the first region; and a proportion of an amount of light exiting the second region relative to an amount of light entering the second region is smaller than a proportion of an amount of light exiting the first region relative to an amount of light entering the first region; wherein transmittances of light at each wavelength are the same in each of the first region and the second region.
