Problems solved by technology
However, the image displayed on the electrical viewfinder 18 is limited by resolution and size and because it is a result of an image signal captured by an image sensor and then processed by a digital signal processor (DSP), distortion when compared to the actual image is observed.
Users may discover blurry images due to non-focusing or hand trembling that is not apparent when shooting them.
Moreover, the electrical viewfinder 18 has high power consumption and has a limited angle of view.
In this situation users are required to hold the camera close to their face, which is not only inconvenient but also slows down shooting.
Additionally, the LCD or LTPS used in the electrical viewfinder 18 costs a significant amount and is not profitable on low-level digital cameras or small-size digital image capturing apparatuses.
Additionally, portable storage devices only provide functions such as data storage, voice recording, and playing MP3 files and do not provide other office functions like image capturing or laser pointing in a meeting.

Embodiment Construction
[0024]Please refer to FIG. 3, FIG. 4, and FIG. 5. FIG. 3 is a front view diagram, FIG. 4 is a rear view diagram, and FIG. 5 is a lateral view diagram of a second digital camera 22 according to the present invention. The second digital camera 22 includes a housing 24, a camera lens 26 for capturing images, a rotating plate 28 installed on the housing 24 in a rotatable manner for protecting the camera lens 26 from dust and dirt, and an optical viewfinder 30, which comprises two optical viewfinder ports 31 installed respectively on the front side and the rear side of the housing 24 for users to view the image of an object. The second digital camera 22 further includes a shutter button 32 for focusing and shooting, a control button set 33 for controlling functions of the second digital camera 22, a connecting port 34 for outputting the photo image data, which conforms to the USB1.1, USB2.0, USB OTG or the IEEE1394 standard, and a reflecting object adjusting device 35.

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.
Description
BACKGROUND OF INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an image capturing apparatus, and more specifically, to an image capturing apparatus with laser-framing viewfinder and laser pointer functions.[0003]2. Description of the Prior Art[0004]In todays modern information based society, information devices are increasingly following the trends of small size, light-weight, and portability. Examples of such devices include: USB flash drives, recording pens, MP3 players and so on. Manufacturers want to integrate as many functions into a portable device as possible and the digital camera is no exception.[0005]Digital cameras have become popular digital products and are positioned to eventually replace conventional film cameras due to low prices and compatibility with other electronic peripherals. Please refer to FIG. 1. FIG. 1 is a front view diagram illustrating a conventional first digital camera 10. The first digital camera 10 includes a camera lens...
