Abstract:
1. An imaging apparatus comprising: an imaging unit configured to photoelectrically convert light of an object image formed by an imaging optical system to generate an image signal; a first detection unit configured to detect an in-focus state of the imaging optical system based on a high-frequency component of the image signal generated by the imaging unit; a sensor configured to generate a pair of image signal by receiving a first object light and a second object light without using the imaging optical system; and a second detection unit configured to detect information related to of an object distance based on a relative displacement amount of the pair of image signal which is generated by the sensor, wherein the sensor is located such that an amount of overlap between a detection range of the first detection unit and a detection range of the second detection unit becomes more than a predetermined amount over a range of overlap between wide-angle and telephoto angle at a predetermined object distance, and wherein in case where the object distance is 3 m, the amount of overlap becomes 100%.
