Abstract:
1. An electronic camera, comprising: an image capturing unit that captures a subject image; an image compression unit that executes a specific type of compression processing on image data obtained by the image capturing unit; and a decision-making unit that makes a decision as to whether or not a camera-shake has occurred if a ratio (d/c) of a data size (d) of a first compressed image data, resulting from the compression processing executed by the image compression unit on first image data obtained by capturing an image following a photographing instruction, and a target data size (c) for the compression processing is substantially smaller than a ratio (b/a) of a data size (b) of a second compressed image data, resulting from the compression processing executed by the image compression unit on second image data captured prior to the photographing instruction, and a target data size (a) for the compression processing on the second image data, wherein: the target data size (c) is a compression target data amount set for the first image data that was captured after the photographing instruction, the target data size (a) is a compression target data amount set for the second image data that was captured before the photographing instruction, and the decision-making unit makes the decision before first image data is recorded on a recording medium.
