Abstract: The present technology relates to a file generation device, a file generation method, a file reproduction device, a file reproduction method, and a program capable of associating an image stored is a file with external data outside the file. A file control unit generates an association-type high efficiency image file format (HEIF) file in which an image in an HEIF file compliant with HEIF and specific information that specifies external data outside the HEIF file, the external data to be associated with the image, are stored in association with each other. Furthermore, the file control unit reproduces the association-type HEIF file. The present technology can be applied to a case where an HEIF file is generated or a case where the HEIF file is reproduced.

Abstract: The present technology relates to a data processing device, a data processing method, and a program that are enabled to easily perform simultaneous generation of a plurality of files in which file streams having different data formats are stored. From an identical image, file data is generated that is obtained by encoding the image and to be stored in each of a plurality of files. First file data stored in one file of the plurality of files and second file data stored in another one file are data different from each other in at least one of codec, chroma format, or bit depth. The present technology can be applied to generation of a plurality of files having the same image content.

Abstract: The present technology relates to a file processing device and a file processing method for enabling restriction of viewing of an image. A file control unit generates a file that stores an encrypted image obtained by encrypting an image with a first encryption key, and an encrypted encryption key obtained by encrypting the first encryption key with a second encryption key, the encrypted image and the encrypted encryption key being associated with each other in the file. The file control unit also decrypts the encrypted encryption key in the file into the first encryption key, and, with the first encryption key obtained by the decryption, decrypts the encrypted image into the image. The present technology can be applied to a digital camera and the like that capture images, for example.

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.

Furthermore, the file control unit detects an image corresponding to a selected related image selected from related images stored in the proxy file. The present technology can be applied to, for example, a case where index display of thumbnail images is performed.

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 in which a reserved area is secured that is used to store relationship information related to association of an image stored in the HEIF file with specification information specifying external data that is outside the HEIF file and is to be associated with the image. Furthermore, the file control unit writes the relationship information into the HEIF file by using the reserved area. 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.

Abstract: An information processing apparatus, information processing method, and program are disclosed. In the information processing apparatus, circuitry is configured to transmit an input command to at least one of a plurality of imaging devices that are associated with the information processing apparatus, the command being executable as a synchronous operation or an asynchronous operation based on information relating to at least one of the imaging devices. The information may, for example, be the number of the imaging devices to which the input command is transmitted. In that example, when the number of the imaging devices is below a threshold amount, the input command is transmitted as the synchronous operation, and when the number of the imaging devices is above the threshold amount, the input command is transmitted as the asynchronous operation.
