摘要： A system and method for permanently backing up RAM memory devices. The present invention utilizes a capacitor as a primary backup device for supplying the necessary backup power for power fluctuations, power interruptions, and other short-duration power failures. The present invention also utilizes a ROM as a secondary backup device for backing up and restoring valid RAM data when the duration of power loss is greater than that for which the capacitor can supply backup power. Thus, the integrity of RAM data is guaranteed for all types of power fluctuations, interruptions, and failures. The ROM includes two storage areas for separately storing two copies of RAM data. The processor first determines whether the data stored in the RAM is valid. If the present RAM data is valid, the processor backs up the present RAM data by replacing the oldest or invalid copy in the ROM with the present RAM data. If the present RAM data is not valid, the processor restores the RAM data with the most recent valid data previously stored in the ROM.

摘要： A method and apparatus for detecting and fixing incorrect dates tagged to digital images is disclosed. The current date on a digital imaging device and the dates tagged to digital images are used to determine any potentially incorrect dates tagged to the digital images. When the date on the digital imaging device is incorrect the dates tagged to the images may be incorrect. When the dates tagged to the images are old, or close to a default date, or have large gaps between groups, the dates may be incorrect. The potentially incorrect dates may be brought to the users attention, and after user conformation the dates are corrected.
摘要翻译：公开了一种用于检测和固定标记为数字图像的不正确日期的方法和装置。数字成像设备上的当前日期和标记为数字图像的日期用于确定数字图像标记的任何可能不正确的日期。当数字成像设备上的日期不正确时，标记为图像的日期可能不正确。当标记为图像的日期较旧或接近默认日期时，或组之间间隔较大时，日期可能不正确。潜在的不正确的日期可能会提请用户注意，在用户建立后，日期将被更正。
