摘要： A method for automatic exposure compensation is disclosed. A shutter is activated and the environmental brightness is detected using a sensor. An exposure value is calculated according to the detection result to obtain a default exposure time. It is determined whether the exposure value is equal to a normal value. If not, a compensation value is calculated based on a shutter-closing curve and a compensation operation is thus executed. Thus, an exposure signal is generated by advancing a first predefined time or postponing a second predefined time, enabling the amount of exposure time to be equal to the addition or subtraction of the default exposure time and the first predefined time.

摘要： A camera having an in-exposure zooming mechanism includes a shutter speed calculation unit for, when an in-exposure zooming mode is set, calculating a shutter speed suitable for the in-exposure zooming mode on the basis of an output from a luminance measurement unit for measuring a luminance of an object. A timer unit outputs a timing signal when the shutter speed elapses. When the timing signal is output, a judgment unit judges whether or not the in-exposure zooming mode is set. A drive control unit drives a motor to change a focal length of a zooming lens when it is determined that the in-exposure zooming mode is set. A shutter closing unit executes a shutter closing operation upon completion of the zooming operation.

摘要： The disclosure relates a piezoelectric element-drive type shutter apparatus for camera. The shutter apparatus includes a main piezoelectric element having a free end which is able to move between a closed position and an opening position to drive shutter blades so as to be opened and closed, and an auxiliary piezoelectric element having a free end for urging the shutter blades toward its closed position when the free end of the main piezoelectric element returns from the opening position to the closed position. When the main piezoelectric element returns to the closed position, i.e. an initial position, the auxiliary piezoelectric element assists the returning movement of the main piezoelectric element. Accordingly, the shutter blades can be closed at a very high speed. This is very effective particularly when a small aperture of the shutter blade is desired. Furthermore, since the returning movement of the main piezoelectric element includes a compulsory force of the auxiliary element as well as a returning force of itself, the returning movement of the main piezoelectric element is insured to be stable as well as speedy, so that very accurate exposure can be obtained.
摘要翻译：本发明涉及一种用于照相机的压电元件驱动型快门装置。快门装置包括主压电元件，其具有能够在关闭位置和打开位置之间移动的自由端，以驱动快门叶片以便打开和关闭;以及辅助压电元件，其具有用于推动快门的自由端当主压电元件的自由端从打开位置返回到关闭位置时，叶片朝向其关闭位置。当主压电元件返回到关闭位置即初始位置时，辅助压电元件有助于主压电元件的返回运动。因此，快门叶片可以以非常高的速度关闭。特别是当需要快门叶片的小孔时，这是非常有效的。此外，由于主压电元件的返回运动包括辅助元件的强制力以及其自身的返回力，所以主压电元件的返回运动保证稳定且快速，从而非常准确可以获得暴露。
