  • Patent number: 8237847
    Abstract: When the user sets an AF frame such that an object tracked as an AF target is in the AF frame, an auto-tracking process starts to detect a face image from the image captured by a television camera. Then, it is determined whether the face image is detected from the peripheral range of the AF frame. If it is determined that the face image is detected from the peripheral range of the AF frame, the position of the AF frame is changed on the basis of the position of the face image. On the other hand, if it is determined that the face image is not detected from the peripheral range of the AF frame, a pattern matching process is performed. The position of the AF frame is changed to the position of the object, which is a tracking target, detected by the pattern matching process.

  • Patent number: 8237804
    Abstract: Upon correcting blur of image capture data of an image capturing device by coded exposure processing, an exposure time and aperture value, which are set by a photometry unit of the image capturing device according to an object, are input, and the exposure time or aperture value is adjusted based on a ratio of shutter open periods in an opening and closing pattern of a shutter used in the coded exposure processing. Then, a gain adjustment value of the image capture data corresponding to a deficiency of an exposure amount by the adjusted exposure time or aperture value is set, image capture by an image capturing unit of the image capturing device is controlled based on the opening and closing pattern, exposure time, and aperture value.

  • Patent number: 8212897
    Abstract: A digital image acquisition system having no photographic film comprises an apparatus for capturing digital images and a flash unit for providing illumination during image capture. The system has a portrait mode for generating an image of a foreground object against a blurred background, the portrait mode being operable to capture first, second and third images (A, B and C) of nominally the same scene. One of the first and second images (A, B) is taken with flash and the other is taken without flash, and the third image (C) is blurred compared to the first and second images. The portrait mode is further operable to determine foreground and background regions of the scene using the first and second images (A, B), and to substitute the blurred background of the third image (C) for the background of an in-focus image of the scene. In one embodiment the in-focus image is one of the first and second images. In another embodiment the in-focus image is a fourth image.
