20130155271 | IMAGE CAPTURE APPARATUS - The present invention relates to an image capture apparatus comprising an image sensor that includes a plurality of first pixel portions and a plurality of second pixel portions whose output signals can be used to perform a correlation operation. In a case of a first photographing condition, the apparatus performs correction processing on output signals from the first pixel portions using output signals from the second pixel portions, and in a case of a second photographing condition, does not perform correction processing on output signals from the first pixel portions using output signals from the second pixel portions. The apparatus also performs image processing on a signal resulting from the correction processing or a signal that was not subjected to the correction processing, and records a signal resulting from the image processing. | 06-20-2013 |
20130182900 | IMAGE PROCESSING APPARATUS, IMAGE SENSING APPARATUS, CONTROL METHOD, AND RECORDING MEDIUM - For obtained raw moving image data, an image processing apparatus decides a focal distance at which a specific subject is focused on. The respective pixels of image signals in each frame of the raw moving image data correspond to light beams having different combinations of pupil regions through which the light beams have passed, and incident directions in an imaging optical system. More specifically, the image processing apparatus generates, from the image signals of each frame of the raw moving image data, a pair of images corresponding to light beams having passed through different pupil regions, and decides, based on a defocus amount at the position of the specific subject that is calculated from the pair of images, the focal distance at which the specific subject is focused on. | 07-18-2013 |
20130308040 | IMAGE CAPTURING APPARATUS AND CONTROL METHOD FOR IMAGE CAPTURING APPARATUS - An image capturing apparatus includes: an imaging element including a first photoelectric conversion cell that outputs a first signal for phase difference detection obtained by detecting a plurality of light fluxes transmitted through different exit pupils of a photographing optical system using a plurality of focus detection pixels and a second photoelectric conversion cell that outputs a second signal for image generation obtained by detecting an object image transmitted through the photographing optical system using an imaging pixel. A contrast calculating unit calculates contrast information on the object image based on at least one of the first signal and the second signal; a focus detecting unit performs focus detection using a phase difference method on the basis of the first signal, and outputs an estimate for focus adjustment; a reliability estimating unit estimates reliability of a result obtained by the focus detecting unit. | 11-21-2013 |
