Digital camera accommodating recording media from other digital cameras
View Patent ↗A signal recording/reproducing apparatus includes a CCD imager. The still image taken by said CCD imager is recorded, together with resolution information, on a recording medium. The recording medium is recorded, together with resolution information, is a still image taken by said digital camera and having a higher resolution than said CCD imager. When a still image is reproduced from said recording medium and displayed on a monitor, a video encoder converts the resolution of a reproduced still image based on resolution information. The converted resolution agrees with a resolution of the monitor. As a result, a reproduced still image is properly displayed on the monitor.
1. A digital camera, comprising:
an imaging device for subjecting incident light to photo-electric conversion on an imaging surface so as to create image data;
a recorder for recording the image data obtained from said imaging device to a removable recording medium in a manner which conforms with any one of N (N: integer) compatible modes out of M (M: integer) compatible modes together with management information indicative of the any one of N (N: integer) compatible modes; and
a reproducer for reproducing the image data in accordance with any one of the M of compatible modes based on the management information recorded in said removable recording medium, wherein the M and N are positive integers satisfying M>N, the M compatible modes include a compatible mode upper than the N compatible modes, the image data is motion image data, and the compatible mode is associated with a frame rate of the motion image data.
2. A digital camera, comprising:
