  • Patent number: 10277795
    Abstract: An image pickup apparatus that is capable of obtaining a high-quality image that is focused on an object designated by a user at the time of reproducing an image. A detection unit detects an object from an image obtained by photographing. A first computation unit computes a distance between the object and the image pickup apparatus as an object distance based on a distance map obtained according to the image. A decision unit decides a focus interval that is an interval of in-focus positions at which objects are focused and a focus frequency that is a count of the in-focus positions according to the object distance and a preset condition. A second computation unit computes the in-focus positions according to the object distance, the focus interval, and the focus frequency. A photographing unit obtains a plurality of images by photographing continuously at the in-focus positions by performing focus bracket photography.

  • 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.

  • Patent number: 8897615
    Abstract: A moving image reproduction apparatus includes an instruction unit, an acquisition unit, a playback speed determination unit, and a moving image reproduction unit. The instruction unit is configured to issue a change instruction for changing a playback target to another moving image while a selected moving image is being played back. The acquisition unit is configured to, if the change instruction has been issued by the instruction unit, acquire a playback time of the moving image which has been played back until the change instruction. The playback speed determination unit is configured to determine a playback speed of the moving image to be played back after the change instruction, according to the playback time. The moving image reproduction unit is configured to play back the moving image instructed for reproduction by the change instruction at the playback speed.

  • Patent number: 8817051
    Abstract: A display control apparatus controls to execute variable magnification processing of a partial image of an image indicated by a display range, and displays the partial image in a display area. The display control apparatus includes a calculation unit which obtains a vertex/vertexes of the display range farthest from a center of the image and sets the vertex or a center point of the vertexes as a reference point, a changing unit which changes a size of the display range while keeping the position of the reference point, and a moving unit which moves the display range in the image. In addition, a display control unit controls to execute the variable magnification processing of the partial image and displays the partial image in the display area. The calculation unit re-calculates the reference point in response to movement of the display range in the image by the moving unit.

  • Patent number: 8570346
    Abstract: At the time of switching an image to be displayed from a first image to a second image with different number of recording pixels with the display scale fixed, display is controlled such that of a partial range displayed in a display region of the image, a relative position of a point farthest from the center of the first image, as to the first image, and of a partial range displayed in a display region of the second image, the relative position of a point corresponding to the farthest point in the first image, as to the second image, are equal. Corresponding ranges between images before and after switching therebetween can be displayed with the display scale fixed, such that the probability of the displayed region extending outside of the entire image is reduced and comparison of images is facilitated.

  • Patent number: 8356034
    Abstract: The attribution information of a plurality of pieces of image data photographed by a plurality of photographing apparatus is obtained. The image data is classified into a predetermined time period on the basis of a photographing date and time obtained from the attribution information. The number of the photographing apparatus photographing the image data classified every predetermined time period is discriminated, and the image data classified into the time period in which the number of the pieces of image data is larger than a threshold value is extracted. The extracted image data is discriminated from the other image data to be displayed. Thereby, even if a plurality of pieces of still image data and moving image data photographed by a plurality of digital cameras and video cameras exists, a candidate of the image data relatively significant among them can be extracted easily.
