<P>PROBLEM TO BE SOLVED: To properly switch a photographing mode when electronic zooming is used. <P>SOLUTION: The imaging device outputs a video generated by imaging a subject by a daytime mode of outputting the video as a color video or a nighttime mode of outputting the video as a monochromatic video. When generating a magnified video for magnifying and displaying the video, in response to a subject luminance Y, the threshold of the subject luminance Y serving as an origin of switching between the daytime mode and the nighttime mode is calculated corresponding to a magnification in generation of the magnified video. <P>COPYRIGHT: (C)2012,JPO&INPIT |
