Abstract: An electronic device includes an image capturing unit configured to generate captured data, a display unit, a communication unit configured to transmit image data based on the generated captured data to an external device, and a controller. When transmitting first image data resulting in a first delay on transmitting the first image data to the external device, the controller causes an image which corresponds to the first image data and is based on the captured data to be displayed on the display unit. When transmitting second image data resulting in a second delay larger than the first delay on transmitting the second image data to the external device, the controller causes an image other than an image corresponding to the second image data to be displayed on the display unit.

Abstract: A method used in an access module that uses a file system to manage a nonvolatile memory of an information recording module enables an available storage space to be calculated in a short time before file data is recorded, and shortens the time required from initialization of the file system to recording. An access module (1) manages information about area management of the file system configured in an information recording module in units of fixed-length blocks. A divisional available storage space calculation unit (103) performs an available storage space calculation process in units of the fixed-length blocks, and completes preparations for recording when detecting a minimum required storage space for recording file data and enables recording of the file data. This shortens the time required from initialization of the file system to recording.

Abstract: Provided is a method for stabilizing and increasing the speed of processing for writing a plurality of different-sized files such as a video file and a management file in parallel in the case where the area in a non-volatile memory of an information recording module is managed by a file system. An access module (1) includes a means for retaining sequential areas in logical block units as areas for writing file data, and a means for realizing file data addition and overwriting by writing data to logical blocks and changing links in a FAT regardless of whether file data addition or overwriting is performed. Writing to the information recording module is performed by writing to sequential addresses in the logical blocks. This realizes the stabilization of and an increase in the file data recording speed by suppressing needless copy processing performed in the information recording module 2 in the case of recording a plurality of files such as a video file and a management file in parallel.

Abstract: When a power source 22 is turned on, recording management information is obtained from a recording medium 70 and the obtained recording management information is analyzed. Whether or not recording of new image data on the recording medium 70 is possible is determined, based on the analysis result. If it is determined that recording the new image data on the recording medium 70 is possible, reception of recording start input that allows the image generation unit and the media management section respectively to generate and record the new image data generation of the new image data by an image generation unit 104 and recording of the new image data on the recording medium 70 is permitted.

Abstract: An imaging device is provided with an internal memory and a controller. The internal memory includes a first area configured to hold device information about the imaging device and a second area configured to hold other information which can include demo data. At least one of the areas within the first area is capable of being defective. The controller is coupled to the internal memory to operate the internal memory to hold and move updated device information within the first area and/or within the second area according to the size of the non-defective areas within the first area.

Abstract: The data transfer apparatus according to the present invention includes a transfer portion that reads out image data stored in a first storage medium, and transfers the image data to a second storage medium; an identification portion that identifies image data stored in the first storage medium and image data stored in the second storage medium; a specification portion that, when transfer of image data by the transfer portion is terminated partway, determines the presence or absence of untransferred image data to the second storage medium among interrelated image data based on the identification result by the identification portion, and that, when the presence of untransferred image data is determined, specifies image data related to the untransferred image data among image data stored in the second storage medium; and a deletion portion that deletes the image data specified by the specification portion from the second storage medium.

Abstract: Even if a write operation onto a storage media on an external storage device is interrupted, consistency of management information on the storage media is improved. An image file transfer device includes a transferor which transfers an image file stored on a storage media to an external device, a retriever which obtains management information in relation to a file system from a storage media included in the external device, before the transfer of the image file by the transferor, a non-volatile storage which stores the management information obtained by the retriever, and a deleter which deletes the management information stored in the non-volatile storage in response to a completion of the transfer of the image file by the transferor.

Abstract: The present invention achieves an electronic device that, when copying video data from a high-capacity recording medium to a plurality of low-capacity recording media, prevents the video data from being divided at an unnatural position. With this electronic device, if the amount of space remaining in a copy destination recording medium is less than the size of the scene to be copied, the scene data is copied into a different copy destination recording medium in the case where the amount of time of the scene data that can be copied into the copy destination recording medium is less than or equal to a predetermined amount of time.
