1. Field of the Invention
The present invention relates to an image photography apparatus and method of manufacturing the same that is capable of photographing an image including a moving image and a still image, and storing and playing the same.
2. Description of the Related Art
A digital still camera (DSC) converts an image provided through a lens, into a digital signal, and stores the digital signal in a recording media such as a hard disk or a memory card. The digital still camera can store a photographed image on the recording media and therefore, does not require a film, and provides the photographed image in a digital format to a computer. Since such a digital still camera has a high compatibility with an external computer system, editing and modification of the image are easy, and the digital still camera can be connected to the external computer system, so that the photographed image may be transferred. However, such a digital still camera is mainly used for photographing a still image due to the limited capacity of the recording media for recording an image. Some DSCs can perform a video recording function for a limited duration. However, since an apparatus for recording a moving image and a sound, and playing the same simultaneously upon play back, should be additionally provided to properly record a moving image, the DSC is substantially inappropriate for recording, storing, and playing a moving image. Therefore, to record a moving image, a recording/playing apparatus for recording an image and a sound onto the recording media such as a tape, and playing the same, is required. A camcorder is typically used to accomplish this.
The camcorder, which mainly uses a cassette tape for the recording media, mounts the cassette tape in its deck and records a moving image. The camcorder also has a microphone and a speaker. Such a camcorder can photograph a still image, but the image quality of that still image is poor when compared to that of the still image photographed by the above-described stand-alone still camera. Therefore, the camcorder is mainly used for photographing a moving image. Since the camcorder has more functions than the DSC and therefore has a complicated construction, the camcorder generally is relatively large and high-priced.
Up to now, as described above, to use each function of the DSC and the camcorder and provide good quality images, the two products should be purchased separately. Therefore, there is a financial burden on users, and because the two products should be carried together in order to capture both still images and moving images, it has been quite inconvenient. Recently, to solve this problem, a product where the function of the DSC and the function of the camcorder, i.e., the apparatus for photographing a still image and the apparatus for photographing a moving image are incorporated into one single product so that a user may selectively use the desired function when necessary, has been developed and sold. A dual cam is one of such products.
However, in the dual cam, since the two functions are incorporated into one single product, problems are encountered such as the product size increases and the structure gets more complicated. In the dual cam, a digital still camera lens for photographing a still image and a digital video camera (DVC) lens for recording a moving image should be arranged together in a narrow space. Particularly, depending on utilization of a space between the digital still camera lens and the board for performing signal transfer to and from the digital still camera, the product size is determined. According to the conventional art, the digital still camera lens and the board thereof are arranged horizontally (that is, an optical axis of the lens and a plane of the board are arranged perpendicularly). In that case, a problem is encountered in that the volume of the dual cam increases. Therefore, an arrangement structure between the digital still camera lens and the board to reduce overall apparatus size is needed.
The present invention has been developed in order to solve the above drawbacks and other problems associated with the conventional art. Therefore, an object of the present invention is to provide an image photography apparatus and method capable of realizing a compactness of the product through efficient arrangement of the digital still camera lens and the board.
To achieve the above object and other advantages, there is provided an image photography apparatus and manufacturing method, wherein a board for performing a predetermined function in the interior of the apparatus and a camera unit including a lens connected to the board so that an electrical signal exchange is possible, are provided, and a reference plane which is a virtual plane perpendicular to an optical axis of the lens, and a plane of the board are substantially perpendicular to each other.
Also, the camera unit is preferably arranged on one corner side of the board, and the camera unit is arranged at the lower end of the board.
Also, the camera unit is preferably directly joined to the board and one corner side of the camera unit is joined to the board.
