20090322933 | IMAGE CAPTURING APPARATUS AND CONTROL METHOD FOR THE SAME - An image capturing apparatus performs autofocus control that uses a face detection function. The image capturing apparatus sets a face region as an AF frame if face detection is successful. However, if a state in which face detection is successful transitions to a state in which face detection has failed, and furthermore a variation between subject distances is less than or equal to a threshold value, the image capturing apparatus maintains the previous AF frame setting instead of changing the AF frame setting. If the variation in subject distances is greater than the threshold value, the image capturing apparatus sets the AF frame to a predetermined region that does not follow a face region. | 12-31-2009 |

First and second focus detection regions are set for a region which has followed the object image detected and a region which does not follow the object image detected. The focus adjustment unit performs a weighted addition of the AF evaluation values based on the output signals in the first and second focus detection regions at ratios depending on at least either a size of an object image within a screen, a position of the object image within the screen and a shooting mode. | 12-31-2009 |

An external ranging unit generates object distance information. A microcomputer performs a TV-AF process using an AF evaluation value of the AF evaluation value signal and an external ranging AF process using the object distance information. The microcomputer controls execution of the two focus control processes according to a result of the detection by the face-detecting section. | 01-07-2010 |
