  • Patent number: 11706396
    Abstract: An image processing apparatus that performs processing concerning the display of a stereoscopic image so as to improve the convenience of a user in viewing a stereoscopic image. A head mount display displays a stereoscopic image using image data including a plurality of images having different viewpoints. The image data is processed based on metadata attached to the image data. In a case where information indicating that the image data is associated with a file format which cannot cause the head mount display to perform display is included in the metadata, the image data is converted into a file format which can cause the head mount display to perform display.

  • Patent number: 10148861
    Abstract: An image pickup apparatus which is capable of easily generating a developed image file from image data obtained using the light field technique. A first recording mode in which data obtained from signals having different focuses is recorded as refocusable first data or a second recording mode in which data which is obtained by carrying out a development process on the data is recorded as non-refocusable second data is selected. During captured image review, at least one focus position in the image data is set as focus information. Based on the recording mode and the focus information, whether to generate a RAW image file or generate a developed image file is determined. When the RAW image file is to be generated and recorded in response to the determination, the focus information is added to the RAW image file.

  • Patent number: 9830683
    Abstract: An image display device capable of saving time and effort required for viewing image data, to which image rotation information unintended by a user is added, in a desired orientation. An acceleration sensor detects an attitude of the image display device. A system controller controls the direction of display of an image based on the image rotation information and the detected attitude of the image display device. When the image display device is rotated from a state where the long side of the image displayed on a monitor and that of the monitor do not match each other, the system controller rotates the image such that the long sides of the image and the monitor match each other, and then, the system controller restricts rotation of the displayed image.

  • Patent number: 9258471
    Abstract: An image pickup apparatus capable of preventing a user who uses another device from knowing the current location of a photographer based on shooting information about an image when an external apparatus distributes the image to the other device. A calculation unit calculates a distance from the shooting location of the image file to the current location of the image pickup apparatus. A distance determination unit determines whether the calculated distance is larger than a predetermined lower limit. A transmission control unit controls to transmit the image file to the external apparatus when the distance determination unit determines that the distance is larger than the lower limit, and not to transmit the image file to the external apparatus when the distance determination unit determines that the distance is not larger than the lower limit.
