Description

  The present invention relates to an imaging technique capable of recording a still image during moving image shooting.

  In general, a digital camera that records a digital image using an image pickup device such as a CCD is equipped with a function of recording not only a still image but also a moving image.

  Such a digital camera is required to have a function of recording a still image at an arbitrary timing during shooting of a moving image, and a still image corresponding to one frame of the moving image during shooting of the moving image is required. A digital camera capable of recording as a snapshot is provided.

  The digital camera as described above has a dedicated storage area for saving and saving still image data as a snapshot. This dedicated storage area is used until a snapshot recording instruction is issued. However, since the storage area for moving image recording is reduced by that amount, smooth moving image recording is hindered.

On the other hand, as described in Patent Document 1, by sharing a storage area for snapshots and a storage area for recording moving images, recording of moving images can be performed while using the memory efficiently. There has been proposed a digital camera capable of performing smoothly.
