Abstract
An imaging apparatus having a function of enabling focus detection at high speed while exposing an image sensor to light. Imaging apparatus 1 has: a first photoelectric converting element (image sensor 10) that converts an optical image formed on an imaging plane into an electrical signal for forming an image signal; and a second photoelectric converting element (phase difference detecting sensor 20) that receives light having passed through the first photoelectric converting element and converts light into an electrical signal for distance measurement.
Claims13
An imaging apparatus comprising:
- an image sensor that comprises a photoelectric converting section;
- and
- a phase difference detecting sensor that detects a phase difference, wherein:
- at least part of the image sensor is formed with a light passing section;
- the photoelectric converting section comprises a substrate;
- the light passing section comprises a thin part formed in the substrate;
- and
- the phase difference detecting sensor is arranged in a location to meet the light passing section and receives light passed through the image sensor and detects the phase difference.
