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.
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.

Abstract: Systems, methods, and devices for applying lens shading correction to image data captured by an image sensor are provided. In one embodiment, multiple lens shading adaptation functions, each modeled based on the response of a color channel to a reference illuminant, are provided. An image frame from the image data may be analyzed to select a lens shading adaptation function corresponding to a reference illuminant that most closely matches a current illuminant. The selected lens shading function may then be used to adjust a set of lens shading parameters.

Abstract: A currently captured image R of an object is displayed nearly at a center portion of a display frame SC on a display screen ST1 that is a shooting mode. When a time dial 22 is rotated for one step in the counterclockwise direction, the currently captured image R is moved rightward. A reproduced image P1 captured before the currently captured image R is displayed on the left thereof. A reproduced image P2 captured before the reproduced image P1 is displayed on the left thereof. The currently captured image R and the reproduced images P1 and P2 are displayed at the same time on a display screen ST2 as a co-existent state of a shooting mode and a reproducing mode. When the time dial 22 is rotated for one step in the counterclockwise direction, only the reproduced images P1 to P4 are displayed on a display screen ST3 that is a reproducing mode. As a plurality of reproduced images, the reproduced images P1 to P4 are displayed along a time axis.

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.
