PHOTOGRAPHING APPARATUS AND CONTROL METHOD FOR PHOTOGRAPHING APPARATUS

摘要

A photographing apparatus of the present invention, having a lens section including a photographing optical system for guiding photographing light flux and a body section capable of being attached to and detached from the lens section, comprises an image sensor having imaging pixels and pairs of focus detection pixels, a first memory for storing information relating to incident angle range of imaging light flux, a second memory, arranged in the body section, for storing information on light receiving sensitivity characteristic of the focus detection pixels, and a control amount calculate section for calculating information for focus adjustment control based on information that has been read out from the first memory and the second memory, wherein the information relating to incident angle range includes information relating to shape of a plurality of arcs based on openings of a plurality of lens groups contained in the photographing optical system.

主权项

1. A photographing apparatus, having a lens barrel including a photographing optical system for guiding photographing light flux and a camera body capable of being attached to and detached from the lens barrel, comprising:
an image sensor having imaging pixels and pairs of focus detection pixels, a first memory, provided in the lens barrel, for storing information relating to incident angle range of imaging light flux on the image sensor, a second memory, arranged in the camera body, for storing information on light receiving sensitivity characteristics of the focus detection pixels, and a control amount calculate section for calculating information for focus adjustment control based on information that has been read out from the first memory and the second memory, wherein information relating to incident angle range includes information relating to shape of a plurality of arcs based on openings of a plurality of lens groups contained in the photographing optical system, and the control amount calculate section calculates incident angle range for light flux incident on the focus detection pixels based on the information relating to incident angle range.
