Monitoring camera device capable of adjusting the changeover between standard time and day light saving time

Abstract

A monitoring camera device adds image capturing time data to image data which is successive with respect to time, and stores the image data on a recording medium. A plurality of directories are prepared on the recording medium for containing a predetermined number of items of image data, and are each named according to a directory naming rule, such that a portion of the name is made different when the directory is prepared during the period of standard time and when the directory is prepared during the period of daylight saving time. The directory also has attached thereto directory preparing time data indicating the time when the directory is prepared. The camera device judges whether each of the directories is prepared during the period of the standard time or during the period of daylight saving time with reference to the name of the directory, and judges the order of directory preparing times using the time indicated by the directory preparing data of the directory when the directory is found to have been prepared during the period of the standard time, or using a value obtained by subtracting a time correction value from the time indicated by the directory preparing data of the directory when the directory is found to have been prepared during the period of daylight saving time.
