  • Patent number: 10484595
    Abstract: An electronic apparatus determines that only a first touch operation moved by a predetermined movement amount in a predetermined time period is a valid operation, and determines that another touch operation is an invalid operation, when a user captures an image while looking into a finder. Then, even when a movement amount by which the touch determined to be the valid operation once is moved in the predetermined time period falls below the predetermined movement amount, the electronic apparatus continuously determines that this touch is the valid operation. Even when a Touch-Up is performed regarding the touch determined to be the valid operation, the electronic apparatus continuously determines that the touch determined to be the invalid operation is the invalid operation.

The scaling circuit receives the N lines of pixel data according to a scaling timing control signal, and refers to a scaling factor to scale up the source image to generate an upscaled image having M lines of pixel data. M is a positive integer greater than N. The output circuit outputs the M lines of pixel data according to an output timing. The timing control circuit determines a receiving timing according to the output timing and the scaling factor to generate the scaling timing control signal, and determines a read timing according to the receiving timing to generate the read timing control signal.

  • Patent number: 10382684
    Abstract: An image capturing apparatus includes a sensor controller and a distance calculator. The sensor controller acquires a target image and a first reference image. The point spread function (PSF) of the target image is point-asymmetric, and the PSF of the first reference image being point-symmetric. The image sensor receives light having passed through a filter region that changes PSFs for sensor images of at least one kind into point-asymmetric forms, and then generates the target image for which a PSF has been changed into a point-asymmetric form by the filter region, and the first reference image that is not the target image. The distance calculator calculates the distance to an object captured in the target image and the first reference image, in accordance with the correlations each between an image obtained by convoluting a blur kernel to the target images and the first reference image.

  • Patent number: 10375293
    Abstract: A method provides phase disparity data. First phase disparity data for a first image frame of a first scene is computed using a phase disparity engine of an image capture device. The method determines whether the image capture device is receiving light from a second scene that is different from the first scene and corresponds to a second image frame. The phase disparity engine discontinues computing of phase disparity data, in response to a determination that the second scene is not different from the first scene. The first phase disparity data are output in connection with the second image frame, in response to determining that the second scene is not different from the first scene.

  • Patent number: 10367989
    Abstract: A digital camera includes a focusing-control-unit that calculates a defocus amount using detection signals of phase difference detection pixels and drives a focus lens according to the defocus amount, and a movement-detection-unit that detects whether a movement is present in a captured subject-image. The focusing-control-unit calculates the defocus amount according to an auto-focus instruction, and drives, in a case where the defocus amount exceeds a threshold-value, the focus lens according to the defocus amount and then performs the phase difference AF again to complete auto-focusing. Further, in a case where the defocus amount is equal to or smaller than the threshold-value, the focusing control unit performs the phase difference AF only once to complete the auto-focusing. Further, in a case where a movement is present in the subject-image, the focusing-control-unit sets the threshold to a larger value than in a case where a movement is not present in the subject-image.
