Power-saving method of image capture device

Abstract

The invention discloses a power-saving method of an image capture device, which is applied to an image capture device with a flash lamp, and comprises the following steps: storing a first exposure travel table and a second exposure travel table in the image capture device; under a normal mode, shooting according to the first exposure travel table by the image capture device; and under a power-saving mode, shooting according to the second exposure travel table by the image capture device, wherein the first exposure travel table has a first shutter speed for correspondingly opening the flash lamp, the second exposure travel table has a second shutter speed for correspondingly opening the flash lamp, and the first shutter speed is faster than the second shutter speed. According to the operation mode of the image capture device, the exposure travel table of the image capture device can be adjusted by the method correspondingly, thus prolonging the service time of the image capture device.

Description

technical field [0001] The present invention relates to a power saving method, in particular to a power saving method of an image capture device. Background technique [0002] An image capture device (for example, a digital camera) is a new product that combines optics, precision machinery and electronic technology. It converts the image captured by the camera lens into a digital image signal through a charge-coupled device (CCD). The processing of the electronic circuit stores the digital image signal in a storage medium, such as a magnetic disk, optical disk or IC memory card. On the other hand, the images can also be immediately displayed on various displays (such as televisions or monitors) for reusing functions such as editing and modification of various images, which is quite convenient and saves time and money. [0003] As digital cameras have gradually become mainstream consumer electronics products in recent years, consumers' requirements for digital camera functio...

However, when a flashlight needs to be used, the flashlight needs to be excited with a fixed excitation intensity, which cannot be adjusted according to the shooting conditions at that time. Therefore, it is easy to consume the power of the digital camera, thereby shortening the usable time of the digital camera. The power saving mechanism of the digital camera is used to save the power of the digital camera, but in the current power saving mechanism of the digital camera, generally speaking, there are two kinds of brightness adjustment of the screen backlight and the time setting of the digital camera entering the power saving mode. However, the above two The amount of electricity that can be saved by the power saving mechanism is still limited
