  • 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: 8630527
    Abstract: The present invention is directed to an image editing apparatus that automatically selects an appropriate frame rate that improves image quality of a new moving image generated by combining a plurality of moving images having different frame rates to prevent a user from working much on the selection, when the user newly creates a moving image. The image editing apparatus of the present invention classifies a plurality of moving images to be combined into groups based on a frame rate, compares an amount of moving images included in each of the groups, and selects the group having the largest amount of moving images belonging thereto. Further, the image editing apparatus compares the amounts of the moving images for respective frame rates included in the selected group to select the frame rate which the largest amount of the moving images has. The image editing apparatus converts moving image to be combined into the selected frame rate and then combines the plurality of converted moving images.

  • Publication number: 20110169982
    Abstract: An image management apparatus which makes it possible to classify picked-up images according to the occasion of going-out without burdening a user. An information processing apparatus manages a plurality of image files obtained through shooting processing by an image pickup apparatus, and acquires GPS information indicative of a location of the image pickup apparatus and a time when the location was detected. The information processing apparatus sets one record of the GPS information as reference start time information, and retrieves a GPS information record indicative of a location identical to the location indicated by the reference start time information, as reference end information. The information processing apparatus classifies image files of respective shooting times occurring between a time indicated by the reference start time information and a time indicated by the reference end time information, into the same group.
