<P>PROBLEM TO BE SOLVED: To provide a digital camera to detect whether a picked-up image is a faulty image immediately after image pickup. <P>SOLUTION: The digital camera is provided with an image frequency arithmetic means 82 for obtaining image data to be temporarily stored in a memory 62 by image pickup, applying arithmetic operation to the frequency of the image data to perform frequency analysis, and extracting a high frequency component; a camera shake determining means 86 for determining whether the extracted frequency component is not greater than a predetermined value; and a camera shake caution LED lighting circuit 88 for allowing a camera shake caution LED 32 to light on the basis of a result of determination of the means 86. When the means 86 determines that the high-frequency component extracted by the means 82 is not greater than the predetermined value, the means 88 allows the LED 32 to light to caution that camera shake may have occurred in the picked-up image. <P>COPYRIGHT: (C)2004,JPO |
