Description

  The present invention relates to an imaging apparatus. More specifically, the present invention relates to an image pickup apparatus that can use image files of different standards without taking time and effort to change settings.

  In general digital cameras, files such as still images and moving images are stored in a recording medium such as an SD card (Secure Digital memory card), a CF card (Compact Flash card), or a memory stick. Since digital camera models are manufactured by various manufacturers, if the file storage location and the various file standards differ for each manufacturer, the compatibility of recorded files between multiple models cannot be maintained. . Therefore, when saving a file, the file is saved in a folder conforming to various standards.

  In a digital camera or the like, the DCF (Design rule for Camera File system) standard, which is a common standard for recording and reproducing image files on a recording medium or the like, is a directory structure or data recording when recording an image file on a recording medium or the like. Standards such as methods are defined to be common among manufacturers. For this reason, as long as the devices comply with the DCF standard, image files can be exchanged even if the manufacturer and model are different.

  On the other hand, recording media such as SD cards, CF cards, and memory sticks are not only used for digital cameras, but are also used as recording media for personal computers and DVD (Digital Video Disk) recorders. For example, in a DVD recorder or the like, an SD card is used for the purpose of recording and reproducing a moving image. In this case as well as in the case of a digital camera, there is a problem of compatibility of recorded files. However, since the DCF standard is established mainly for use with a digital camera, There are aspects that are not suitable for recording and playback. Therefore, a common standard SD-Video standard for recording moving images on an SD card has been established.

  In order to improve the usability of a digital camera compliant with the DCF standard, proposals have been made to improve usability by creating and recording folders and files other than the DCF standard on a recording medium.

For example, a method for facilitating playback and editing with a digital camera by recording unnecessary image files in a folder that does not satisfy the DCF standard on a recording medium has been proposed. (For example, see Patent Document 1)
In addition, a method has been proposed in which an alias management file is prepared in addition to the DCF standard in a digital camera compliant with the DCF standard, and the folder name of the DCF standard is given an alias to facilitate management. (For example, see Patent Document 2)

  In recent years, it has become possible to record a moving image for a long time even with a digital camera, and there has been a growing demand for reproducing and watching recorded moving images on a device such as a home DVD (Digital Video Disk) recorder. However, as described above, even a device such as a DVD recorder that can use the same recording medium as the digital camera cannot be played back because the standard for recording and playing back files is different.

  In order to cope with such problems, even in a digital camera compliant with the DCF standard, it is possible to record and reproduce a moving image recording on a recording medium such as an SD card in accordance with another standard such as the SD-Video standard. It is.

  However, when playing back a moving image file recorded in the SD-Video standard in a digital camera, the user needs to switch the playback performed based on the DCF standard that is normally used to be based on the SD-Video standard. That is, since the user cannot search or display a moving image recorded in the SD-Video standard in the reproduction based on the DCF standard that is normally used, it is necessary to switch the setting of the digital camera every time a moving image file is reproduced or edited. there were.

  Conversely, when playing back based on the SD-Video standard, still images recorded based on the DCF standard cannot be retrieved or displayed. As described above, since still images recorded with the digital camera based on the DCF standard and videos recorded with the SD-Video standard cannot be managed in a unified manner, a target video is searched for, played back, and edited. It was difficult. For example, it is very troublesome to select and delete unnecessary files when the remaining recording capacity of the recording medium is low.

  In addition, for longer recording time, it is possible to record on a large-capacity recording medium such as a hard disk or server connected to the digital camera by wire or wireless without recording on the recording medium set in the digital camera. Has come to be done. In such a case, when recording a moving image on a hard disk, a server, or the like, if the recording is performed according to, for example, the SD-Video standard, which is suitable for recording a moving image, the target moving image is recorded with a digital camera in the same manner as when recording on a recording medium. There is a problem that it is difficult to search and play or edit.

  The present invention has been made in view of the above problems, and in an imaging apparatus capable of setting a plurality of types of standards, the settings are changed even if the standards set for image recording and image playback are different. It is an object of the present invention to provide an imaging device with good operability that can reproduce a recorded image without using it.
