Abstract: A focusing auxiliary device of an image-capturing apparatus includes a base and an extension rod. The base is arranged on the image-capturing apparatus. The extension rod is coupled to and movable relative to the base for sustaining against a supporting surface so as to keep the lens set of the image-capturing apparatus at a fixed distance from an object to be photographed. By marking graduations on the extension rod, the focusing distance from the image-capturing apparatus to the object can be realized at the same time.

Abstract: An image capturing apparatus with a laser-framing viewfinder includes a housing, a laser source installed inside the housing for generating a laser beam, a first lens installed inside the housing for diverging the laser beam, a framing mask for masking the laser beam diverged by the first lens to form a laser-framing viewfinder, and a camera lens installed in the housing for capturing an object in the laser-framing viewfinder.

Abstract: A digital camera capable of detecting whether to be stable is provided. The digital camera includes a housing, a lens formed on the housing for inputting light, a photosensor for sensing the inputted light, an image generator for generating an image based on the sensed light, and a trigger disposed on the housing for generating a trigger signal while the housing is fixed. The digital camera is able to adjusting its operation as the housing is fixed.

Abstract: An image capturing apparatus includes a lens for capturing an image of an object, focusing module for focusing the lens, and a focus-decisive module including at least one slide rod for measuring a distance between the lens and the object and for controlling the focusing module to focus the lens synchronously according to the distance.

Abstract: A laser source is installed inside a housing for generating a laser beam. A first lens group is installed inside the housing for diverging the laser beam from the laser source. A reflecting object is installed inside the housing in a rotatable manner for reflecting the laser beam from the first lens group. A second lens group is installed inside the housing for diverging the laser beam from the reflecting object. A framing mask masks the laser beam and displays a laser-framing viewfinder. A third lens group is installed on the housing for focusing the laser beam. A camera lens is installed on the housing for capturing an image framed in the laser-framing viewfinder. When the reflecting object rotates to a first location a laser-framing viewfinder is generated. When the reflecting object rotates to a second location a laser pointer is generated.

Abstract: A hooking-type fully automatic electric meter with a function of fully automatic detecting and choosing a measuring mode among the electric current, voltage and resistance measuring modes. A user only needs to turn on the electric power of the electric meter without performing any other procedures; he can get an accurate reading of the volume of electricity on the display screen. The meter is different from the manually selected clamping type meters with different functional positions for measuring the values of electric current, voltage and resistance. With the meter, damage to the main body of the electric meter in operating electric measuring and to the safety of the user himself can be avoided. This can significantly raise the industrial safety in measuring large volume of electric current, and can save actions and time for operating the electric meter, and convenience and efficiency in operating can be increased.
