Abstract

The invention provides an imaging apparatus, which includes an imaging unit configured to receive an optical image transmitted through a lens unit and configured to convert the image into image data, a target image detection unit configured to detect a target image satisfying a predetermined form from the image data converted by the imaging unit, and a focus control unit configured to move a focus position of the lens unit by a predetermined amount according to a result of the target image detected by the target image detection unit. The target image detection unit detects the target image from image data converted by the imaging unit in the moved focus position when the focus control unit moves the focus position of the lens unit by the predetermined amount according to the detected result of the target image.

Description

technical field [0001] The present invention relates to an imaging apparatus and an imaging method for detecting an object image from a captured image. Background technique [0002] Conventional imaging devices such as digital cameras have various functions that enable users to successfully take pictures. An example of such a function is the auto focus function for automatically focusing on the subject to be photographed to obtain a good image. Furthermore, in recent years, imaging apparatuses are provided with a function of detecting the face of a person as a subject through image recognition processing and automatically focusing on the detected face when taking a photo of a person. [0003] Many methods for detecting human faces have been proposed. By one method, a face candidate area corresponding to the shape of a person's face is extracted, and the face area is determined based on the characteristics of the candidate area. However, with the current face detection tec...
