20100067892 | IMAGING APPARATUS AND CONTROL METHOD - In an imaging apparatus, wherein when performing auto focus control while continuously moving a focusing lens by using an image sensor that has a lag in timing of electric charge accumulation, a focusing accuracy can be improved. To this end, the imaging apparatus includes the rolling shutter function, an imaging unit configured to convert an object image into an image signal, and a setting unit. When a difference exceeds a predetermined amount in the barycentric position of the optical system between an upper line and an a lower line of the AF area due to the rolling shutter function, the setting unit imposes a limitation on the AF area to reduce the size of a desired AF area to an AF area where the difference in the barycentric position becomes a predetermined amount. | 03-18-2010 |
20100098397 | AUTO FOCUS SYSTEM HAVING AF FRAME AUTO-TRACKING FUNCTION - Disclosed is an auto focus system having an auto focus (AF) frame auto-tracking function that detects the image of an object to be tracked as an AF target using a pattern matching process and moves an AF frame indicating an AF target range to the position of the object, thereby tracking the object. When a person's face (face image) is included in the AF frame, the auto focus system having an AF frame auto-tracking function automatically sets the AF frame in an appropriate range so as to correspond to the position and size of the face image. Therefore, even when the size of the face image is changed, it is possible to appropriately track the face and perform focusing on the face. | 04-22-2010 |
20100209093 | FOCUS ADJUSTING APPARATUS AND FOCUS ADJUSTING METHOD - There are provided a focus adjusting apparatus and method in which judgment of an object area to be focused can be favorably performed when the judgment of the object area to be focused is executed at the time of image-taking preparation operation. In the focus adjusting apparatus and method, a first operation of determining the object area to be focused is performed prior to the image-taking preparation operation, and a second operation different from the first operation is performed to execute a focusing operation at the time of the image-taking preparation operation. Prior to the first operation, whether or not an object to be focused can be predicted is judged to change a manner of the first operation based on a result of a judgment. | 08-19-2010 |
20100310248 | METHOD AND SYSTEM FOR AUTO-FOCUSING - Method and system for auto-focusing. The method includes checking for presence of a subject in a first frame. The method also includes determining a second frame indicative of an in-focus position of the subject if the presence of the subject is detected. The method further includes causing to focus on the subject based on the second frame. Further, the method includes checking for a change in at least one of location of the subject in the second frame, and sharpness and luminance in an area corresponding to the subject in the second frame. Moreover, the method includes causing to refocus on the subject if the change is detected. | 12-09-2010 |
20100316365 | IMAGE CAPTURING APPARATUS AND METHOD FOR CONTROLLING SAME - The present invention further improves operability related to setting the position and size of a focus detection region. An image capturing apparatus of the invention is provided with an image sensor that photo-electrically converts an object image formed by an optical lens, a focus detection unit that detects the focus state of the object image using an image signal from a focus detection region that is a region that is a portion within a frame of the image sensor, a setting unit that sets one focus detection mode from among a plurality of focus detection modes in which the size and position of the focus detection region within the frame differ, and a storage unit that stores a focus detection region size and position for each of the plurality of focus detection modes. | 12-16-2010 |
20110002680 | METHOD AND APPARATUS FOR FOCUSING AN IMAGE OF AN IMAGING DEVICE - A method and apparatus for focusing an image in an image-capturing device utilizing at least one face in the image. The method includes detecting at least one face in the image, determining the size of the detected at least one face, determining the distance of the at least one face from the image-capturing device, wherein the determination utilizes the size of the detected at least one face, and focusing an image according to the determined distance of the detected at least one face. | 01-06-2011 |

The focus-point selection system selects a subset of focus points corresponding to the location of a target in an image capturing area from a plurality of focus points positioned at predetermined locations. The target is a subject that is brought into focus according to a phase-difference autofocus method. The image sensor generates an image signal corresponding to the captured optical image. The target detector detects the target on the basis of the image signal. The location detector detects a subject location. The subject location is a location of the target detected by the target detector in the image capturing area. The first selector selects the focus point with the shortest distance from the subject location. | 08-18-2011 |
