IMAGING APPARATUS AND METHOD FOR CONTROLLING IMAGING APPARATUS

摘要

An imaging apparatus, comprises an imaging optical system; a birefringent optical unit configured to separate a ray into an ordinary ray and an extraordinary ray; a light selection unit constituted by an ordinary ray selection element and an extraordinary ray selection element; an image sensor constituted by a first pixel group that receives an extraordinary ray, and a second pixel group that receives an ordinary ray; an image generation unit configured to generate an ordinary ray image based on signals acquired from pixels belonging to the first pixel group, and generate an extraordinary ray image based on signals acquired from pixels belonging to the second pixel group; and an image processing unit configured to calculate a subject distance, using the ordinary ray image and the extraordinary ray image.

1. An imaging apparatus, comprising:
an imaging optical system; a birefringent optical unit configured to separate a ray that passed through the imaging optical system into an ordinary ray and an extraordinary ray; a light selection unit constituted by an ordinary ray selection element configured to implement transmitting an ordinary ray entering from the birefringent optical unit and an extraordinary ray selection element configured to implement transmitting an extraordinary ray entering from the birefringent optical unit; an image sensor constituted by a first pixel group that receives an extraordinary ray transmitted through the extraordinary ray selection element, and a second pixel group that receives an ordinary ray transmitted through the ordinary ray selection element; an image generation unit configured to generate an ordinary ray image based on signals acquired from pixels belonging to the first pixel group, and generate an extraordinary ray image based on signals acquired from pixels belonging to the second pixel group; and an image processing unit configured to calculate distance information relating to a subject, using the ordinary ray image and the extraordinary ray image.
