DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a power saving method, and more particularly to a power saving method for a device. ^像撷[Prior Art] General image capture devices, such as digital cameras, digital cameras, etc., for T to achieve power saving purposes, pass f in the boot _ segment without any operation will enter standby mode (Standb.y Mode) (ie power saving mode). In the standby mode, the image capture device automatically turns off the LCD screen to save some power. For example, U.S. Patent No. 4,555,170 discloses a device for controlling the display screen for turning off the light source of the display screen when no operation is performed. Then, after a period of time, if there is still no operation, the auto power off mode will be entered, that is, the lens is retracted and then the power is turned off. Although the above method can be used to achieve power saving (4), however, since the image capturing device performs an initializing operation at the time of power-on, and then enters the standby mode and then returns to the active mode < (Active M〇de), The initialization # operation must be re-executed, which will result in increased power consumption and increased startup time. At present, the miniaturized image capturing device has the advantages of being thin and thin, easy to carry π, and convenient to use, but the most criticized is the problem of power consumption, so if more power can be saved in a limited power supply, More time will be added.

The flag value is read, and the current operation mode of the image capturing device is determined according to the flag value. When the flag value is a first flag value, it indicates that the image capturing device is currently in a shutdown mode, and determines whether a signal corresponding to a switching button is received. If the signal corresponding to the switching key is received, the flag value is reset to a third flag value. The lens of the image capturing device is extended to perform an initialization operation, and the initialization data is stored in one of the memory of the image capturing device. It is judged whether a standby signal has been received or has been waiting for a first time interval. If the standby signal is received or the first predetermined time has elapsed, the initialization data or the setting data is stored in the memory. Then, the flag value is re-stated to a second flag value, and the power of the image capturing device is turned off, so that the image capturing device enters a standby mode. When the flag value is a second flag value, it indicates that the image capturing device is currently in a standby mode to determine whether a signal corresponding to an adjustment button is received. If the signal corresponding to the adjustment key is received, the flag value is reset to the third flag value, and the initialization data or the setting data in the memory is read to perform a corresponding adjustment operation. It is judged whether the above standby signal is received or the first predetermined time has been waited for. If the standby signal is received or has waited for the first predetermined time, the initialization data or the setting data is stored in the above memory. Then, the flag value is reset to the second flag value, and the power of the image capturing device is turned off, so that the image capturing device enters the standby mode. If the signal corresponding to the adjustment button is not received, it indicates that the image capturing device is still in the standby mode, and it is determined whether the standby signal is received or has been waited for 0757-A21162TWF(N2); E0105144; alexchen 7 correction no 1299813 Amendment date 94131453: 97.4.10 Amendment page to the above-mentioned scheduled time.
