  • Publication number: 20220309035
    Abstract: The present technology relates to a file processing device, a file processing method, and a program that enable association of, for example, an image stored in a file with external data outside the file. A file control unit generates a high efficiency image file format (HEIF) file storing relationship information related to association between an image and specification information. The relationship information includes the specification information that is before being assigned to external data and specifies the external data that is outside the HEIF file and is to be associated with the image stored in the HEIF file. Furthermore, the file control unit writes the specification information stored in the HEIF file into the file storing the external data. The present technology can be applied to, for example, a case where a HEIF file is generated and an image stored in the HEIF file is associated with external data later, and the like.

  • Patent number: 9560257
    Abstract: The present invention relates to an information processing apparatus by which image data can be downloaded simply. A video camera 11 receives thumbnail images corresponding to one or more images included in an album from a video camera image station 41 and displays the thumbnail images on an LCD unit. If one or more images to be downloaded are selected, then the video camera 11 acquires image information of the selected image or images from a video camera image station 41, analyzes the image information and discriminates it one by one image whether or not the selected image data are downloadable. Every time one image is discriminated to be downloadable, the video camera 11 accesses a corresponding URL designated for each image, downloads the image from the URL and records the image onto a recording medium. The video camera 11 successively downloads the selected images in this manner.
