Description

  The present invention relates to a technique for recording image data applied to a digital camera or the like that converts an optical image into an electrical signal using, for example, an image sensor and records image data of a still image or a moving image on a recording medium.

  In recent years, digital cameras have rapidly increased in pixel count and image quality. For example, an image sensor such as a CCD or a COMS, which was about 1 million pixels a few years ago, has exceeded 10 million pixels. As a result, the image data size has increased, for example, the image data size of about 300 KB (kilobytes) per image exceeds 30 MB (megabytes).

  In addition, not only still images but also digital cameras that can record moving images by a method of recording still images at high speed and continuously according to standards such as motion JPEG have appeared. The image size was about 60 KB / sec for SQVGA (160 x 120 pixels), but about 1 MB / sec for VGA (640 x 480 pixels) has also appeared, increasing the image data size as with still images. doing.

  The digital camera body is provided with a slot for inserting a recording medium (medium) used as means for recording image data. Previously, FD (floppy (registered trademark) disk) or the like was used as a recording medium. However, since the capacity is about 1 to 4 MB, there is a problem that increased image data cannot be recorded on one recording medium. It was. Therefore, Japanese Laid-Open Patent Publication No. 2000-69417 proposes a method of dividing and recording image data on a plurality of recording media by replacing the recording media with slots.

  On the other hand, in recent years, the capacity of recording media has been increasing as with digital cameras, and some recording media such as CF (Compact Flash (registered trademark)) and MD (Microdrive) have a capacity of 1 GB. ing. However, even if a 1 GB recording medium is used, only about 30 frames can be taken when a still image is taken with the highest image quality.

  In addition, if it is a moving picture, it can shoot only about 16 minutes continuously. In order to shoot more images, it is necessary to have a plurality of recording media and replace them with unrecorded recording media when recording on the recording media inserted into the slots becomes impossible. Therefore, in order to eliminate the troublesomeness of exchanging the recording medium, Japanese Patent Application Laid-Open Publication No. 2004-228620 proposes a camera that can mount a plurality of recording media on the camera body.

  Here, when recording image data on a plurality of recording media, in order to facilitate classification / retrieval of the recording image data, the same publication discloses recording from a plurality of recording media according to shooting distance, shooting conditions, and the like. A method for selecting a recording medium is disclosed.

Further, in Patent Document 2 below, when the image data size is larger than the reference value, recording is performed on a recording medium having a large capacity, and when the image data size is smaller than the reference value, recording is performed on a recording medium having a small capacity. A method has been proposed in which data is recorded on a recording medium with a large capacity when the data is uncompressed data or a moving image, and is recorded on a recording medium with a small capacity when the image data is compressed data or a still image.

The integration of the image data is performed based on information on the division coordinates and the number of divisions described in each piece of image information. The image data is integrated into a file as shown in FIG. In S14, the camera power is turned off to end the series of operations.

Further, it is possible to automatically return the divided image data to the original image data. In the above description, since the two recording media are provided, the main image data is divided into two. However, there is no problem even if the number of recording media is larger. It does not matter as long as it is less than a few. Although the image data has been described as data in the RAW mode, there is no problem even if the image data is JPEG, TIF, or the like.
