  • Patent number: 8238738
    Abstract: One embodiment of the present invention provides a plenoptic camera which captures information about the direction distribution of light rays entering the camera. Like a conventional camera, this plenoptic camera includes a main lens which receives light from objects in an object field and directs the received light onto an image plane of the camera. It also includes a photodetector array located at the image plane of the camera, which captures the received light to produce an image. However, unlike a conventional camera, the plenoptic camera additionally includes an array of optical elements located between the object field and the main lens. Each optical element in this array receives light from the object field from a different angle than the other optical elements in the array, and consequently directs a different view of the object field into the main lens. In this way, the photodetector array receives a different view of the object field from each optical element in the array.

  • Patent number: 8218963
    Abstract: Using photographic flash for candid shots often results in an unevenly lit scene, in which objects in the back appear dark. A spatially adaptive photographic flash (100) is disclosed, in which the intensity of illumination (21, 23) varies depending on the depth and reflectivity (30, 101) of features in the scene. Adaption to changes in depth are used in a single-shot method. Adaption to changes in reflectivity are used in a multishot method. The single-shot method requires only a depth image (30), whereas the multi-shot method requires at least one color image (40) in addition to the depth data (30).

  • Patent number: 8195042
    Abstract: 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.

  • Patent number: 8174610
    Abstract: A camera includes an image sensor, and a plurality of metering areas are assigned to an object scene captured by the image sensor. A CPU evaluates a luminance of the object scene for each metering area, and binarizes each of the plurality of obtained luminance evaluated values. Furthermore, on the basis of the plurality of binarized luminance evaluated values, a width of a high luminance area included in the object scene is calculated while a width of an adjacent area adjacent to the high luminance area out of a low luminance area included in the object scene is calculated. Then, each of the plurality of luminance evaluated values is corrected on the basis of a ratio between the width of the calculated adjacent area and the width of the calculated high luminance area. An exposure amount to the image sensor is adjusted on the basis of the luminance evaluated values thus corrected.

  • Patent number: 8164682
    Abstract: The invention utilizes an autofocus system (806) that is capable of very fast changes in focus over a relatively small portion of the focus range of the focusing system. When operating continuously in a repeating series of images or frames such as are found in preview mode or in video capture, autofocus images are captured before and after each video frame wherein the autofocus images have different focus settings than the images in the series. The autofocus images are then evaluated for focus quality to determine whether focus adjustments are needed.
