1. An image pickup device, comprising:
- an image pickup unit that converts an image projected by an optical system into image data and outputs the image data;
a storage unit that stores the image data output from the image pickup unit;
a detection unit that detects an emission position of a signal emitted from an external device from the image data stored in the storage unit; and
a focus control unit that sets an area as a target of focus adjustment based on the detected emission position of the signal and adjusts a focus of the optical system so as to maximize a frequency component within a preset frequency band of image data of the area as the target of the focus adjustment.

Abstract
An image pickup device includes: an image pickup unit that converts an image projected by an optical system into image data and outputs the image data; a storage unit that stores the image data output from the image pickup unit; a detection unit that detects an emission position of a light beam emitted from an external device from the image data stored in the storage unit; and a focus control unit that sets a focus detection area based on the emission position of the light beam and makes a focus adjustment mechanism adjust a focus of the optical system so as to maximize a high frequency component in the focus detection area.
