## Background
FIELD OF THE INVENTION
The present invention relates to a mouse with a shooting function and an image pickup system, and more particularly to a mouse with an image pickup device and an image pickup system using such a mouse.
BACKGROUND OF THE INVENTION
With rapid development of electronic and information industries, image pickup devices become essential electronic devices in our daily lives. Generally, image pickup devices are used to take photographs or record video data. In addition, image pickup devices are also applied to web cameras for making a video conference. Recently, the built-in image pickup devices of notebook computer or the external pickup devices connected with desktop computers are gradually adopted.
With increasing development of digital techniques, text documents are gradually created as electronic files. Generally, text documents are scanned by scanning apparatuses and then saved as electronic files such as PDF (Portable Document Format) files. In a case that no scanning apparatus is in communication with the notebook computer, the images of simple documents such as single-sided papers or business cards may be captured by the computer peripheral devices (e.g. image pickup devices). The images captured by the built-in image pickup device are usually saved as JPEG (Joint Photographic Experts Group) files. However, most users prefer using scanning apparatuses to scan the text documents as PDF files because the texts and signs contained in the PDF files are readable by the computer systems and may be converted into editable text files
As known, an optical character recognition (OCR) technique is a process of capturing an image of a document and then extracting the texts from that image. After an image of a document is captured by an image pickup device and saved as a JPEG file, the JPEG file may be analyzed according to the OCR technique. As a consequence, individual texts or signs contained in the JPEG file will be recognized and converted as an editable text file. Since the OCR technique is well established, image pickup devices are gradually adopted to acquire electronic image files of the documents.
Nowadays, a mouse having a shooting function has been introduced into the market. Generally, an image pickup device is installed on a casing of this mouse. The mouse may be used to control cursor movement of a computer system or select an icon shortcut. While the operation of the computer system is controlled by the user through the mouse, the image pickup device of the mouse may be used to shoot the document to acquire an electronic image file of the document.
Generally, there are two ways of using the image pickup device of the mouse to shoot the document. In the first way, the document is held by a user's hand, and the mouse is placed on a working plane (e.g. a desk plane) to shoot the document. In the second way, the document is placed on the working plane, and the mouse is held by the user's hand to shoot the document that is placed on the working plane. The way of holding the document by the user's hand and the way of holding the mouse are unsatisfied because the obtained images (i.e. the electronic image file of the document) are usually blurred. If the document or the mouse is handheld, the document or the mouse is readily rocked because of a handshaking action. Consequently, the document is blurred.
Moreover, in views of cost-effectiveness, the lens of the image pickup device of the mouse usually has a fixed focal length, and the focal length of the lens is not adjustable. In a case that no preview screen is used, it is difficult to precisely allow the image pickup device to focus on the document to shoot the document. Under this circumstance, the document image acquired by the image pickup device is still blurred.
Therefore, there is a need of providing a mouse with a shooting function and an image pickup system using such a mouse in order to enhance the shooting quality.

The components of the mouse 10 for controlling the cursor 221 include a left button, a right button and a scroll wheel. The operating principles of these components are well known in the art, and are not redundantly described herein.
Hereinafter, the detailed configurations of the mouse 10 with the shooting function will be illustrated with reference to FIGS. 2 and 3. FIG. 2 is a schematic perspective view illustrating the mouse of the image pickup system in a cursor control mode according to an embodiment of the present invention. FIG. 3 is a schematic perspective view illustrating the mouse of the image pickup system in a shooting mode according to an embodiment of the present invention. The mouse 10 comprises a casing 11, a supporting member 12 and an image pickup device 13.
The image pickup device 13 is arranged at a first end of the casing 11 (e.g. a rear end of the casing 11) for shooting a business card B (see FIG. 4). In this embodiment, the image pickup device 13 is arranged at the rear end of the casing 11.
The supporting member 12 comprises a first extension arm 121, a first notch 122, a second extension arm 123, a second notch 124, a handle part 125. The first extension arm 121 is arranged at a first side of the casing 11, and extensible from the casing 11 toward the first end of the casing 11 (i.e. the rear end of the casing 11). The notch 122 is disposed in a first end 1211 of the first extension arm 121 for accommodating a first edge of the business card B. The second extension arm 123 is arranged at a second side of the casing 11, and extensible from the casing toward the first end of the casing 11 (i.e. the rear end of the casing 11). The second notch 124 is disposed in a first end 1231 of the second extension arm 123 for accommodating a second edge of the business card B. The handle part 125 is arranged between the first end 1211 of the first extension arm 121 and the first end 1231 of the second extension arm 123, and connected with the first extension arm 121 and the second extension arm 123. By grasping the handle part 125, the supporting member 12 may be pulled out of the casing 11.
The casing 11 comprises a first receptacle 111, a second receptacle 112 and a third receptacle 113 (see FIG. 1). The first receptacle 111 is arranged at a first side of the casing 11 (e.g. the left side of the casing 11 as shown in FIG. 3) for accommodating the first extension arm 121, so that a second end 1212 of the first extension arm 121 and a first end 1111 of the first receptacle 111 are in contact with each other. The second receptacle 112 is arranged at a second side of the casing 11 (e.g. the right side of the casing 11 as shown in FIG. 3) for accommodating the second extension arm 123, so that a second end 1232 of the first extension arm 121 and a first end (not shown) of the second receptacle 112 are in contact with each other. The third receptacle 113 is arranged at the first end of the casing 11 (i.e. the rear end of the casing 11) and disposed under the image pickup device 13 for accommodating the handle part 125. When the first extension arm 121, the second extension arm 123 and the handle part 125 are respectively accommodated within the first receptacle 111, the second receptacle 112 and the third receptacle 113, the mouse 10 is operated in a cursor control mode (see FIG. 2).
When the first extension arm 121 and the second extension arm 123 are pulled out to respectively move the second end 1212 of the first extension arm 121 and the second end 1232 of the second extension arm 123 to a second end 1112 of the first receptacle 111 and a second end 1122 of the second receptacle 112, the mouse 10 is operated in a shooting mode (see FIGS. 3 and 4). In this situation, after the business card B is accommodated within the first notch 122 and the second notch 124, the distance between the business card B and the image pickup device 13 is substantially equal to a shooting distance D. Moreover, the casing 11 further comprises a first triggering switch 114 and a second triggering switch 115. The first triggering switch 114 is disposed within the first receptacle 111 and arranged beside the second end 1112 of the first receptacle 111. The second triggering switch 115 is disposed within the second receptacle 112 and arranged beside the second end 1122 of the second receptacle 112. When the first extension arm 121 and the second extension arm 123 are pulled out and respectively located at the second end 1112 of the first receptacle 111 and the second end 1122 of the second receptacle 112, the first triggering switch 114 and the second triggering switch 115 are no longer pushed by the first extension arm 121 and the second extension arm 123. Under this circumstance, the operating mode of the mouse 10 is changed to the shooting mode. On the other hand, when the first extension arm 121 and the second extension arm 123 are respectively accommodated within the first receptacle 111 and the second receptacle 112, the first triggering switch 114 and the second triggering switch 115 are pushed by the first extension arm 121 and the second extension arm 123. Under this circumstance, the operating mode of the mouse 10 is changed to the cursor control mode.
It is noted that the shooting distance D is equal to the focal length of the image pickup device 13. Consequently, after the business card B is accommodated within the first notch 122 and the second notch 124 and the business card B is shot by the image pickup device 13, a sharp business card image will be acquired. Moreover, for assuring that the distance between the business card B and the image pickup device 13 is substantially equal to a shooting distance D, the lengths of the first extension arm 121 and the second extension arm 123 and the locations of the first notch 122 and the second notch 124 should be elaborately predetermined by calculation.
Hereinafter, the operations of the image pickup system 1 will be illustrated with reference to FIG. 4. FIG. 4 is a schematic view illustrating the operations of the image pickup system of the present invention, in which the mouse is operated in the shooting mode. For using the image pickup system 1 to shoot the business card B, the first extension arm 121 and the second extension arm 123 may be pulled out of the first receptacle 111 and the second receptacle 112, so that the second end 1212 of the first extension arm 121 and the second end 1232 of the second extension arm 123 are respectively moved to a second end 1112 of the first receptacle 111 and a second end 1122 of the second receptacle 112. Since the first triggering switch 114 and the second triggering switch 115 are no longer pushed by the first extension arm 121 and the second extension arm 123, the mouse 10 is changed from the cursor control mode to the shooting mode. As the mouse 10 enters the shooting mode, the shooting program 30 installed in the computer host 21 is activated and the image pickup device 13 arranged at the first end of the casing 11 is enabled.
Then, when the business card B to be shot is placed within the first notch 122 and the second notch 124, a pre-shot business card image 312 of the business card B is simultaneously shown on the preview interface 31, and the pre-shot business card image 312 is included in the positioning frame 311. At this moment, the shooting program 30 may judge whether the business card B is placed in the right position according to the condition whether the pre-shot business card image 312 is completely included in the positioning frame 311. If the shooting program 30 judges that the business card B is placed in the right position, it means that the distance between the business card B and the image pickup device 13 is substantially equal to a shooting distance D. Meanwhile, a shooting signal is transmitted to the image pickup device 13. In response to the shooting signal, the image pickup device 13 shoots the business card B, thereby acquiring the business card image.
After the shooting operation is completed, the business card B may be removed from the first notch 122 and the second notch 124. Then, the first extension arm 121, the second extension arm 123 and the handle part 125 are respectively accommodated within the first receptacle 111, the second receptacle 112 and the third receptacle 113. Meanwhile, the first triggering switch 114 and the second triggering switch 115 are pushed by the first extension arm 121 and the second extension arm 123, so that operating mode of the mouse 10 is changed to the cursor control mode. Consequently, the user may operate the mouse 10 to move the cursor 221.
From the above description, the mouse of the image pickup system of the present invention comprises a supporting member for supporting a business card and an image pickup device for shooting the business card. Consequently, the business card to be shot can be securely placed on the supporting member, and during the shooting process, the mouse is placed on a working plane (e.g. a desk plane). Since the image pickup device is fixed on the mouse that is placed on the working plane and the business card is securely placed on the supporting member, the business card image acquired by the image pickup device will be sharp because the adverse influence of the handshaking action is eliminated. Moreover, since the focal length of the image pickup device for shooting the business card and is taken into consideration to design the supporting member, the distance between the business card supported on the supporting member and the image pickup device is equal to the shooting distance (i.e. the focal length of the image pickup device). Under this circumstance, the image pickup device of the mouse of the present invention can precisely focus on the business card in order to obviate the drawbacks encountered from the prior art.
While the invention has been described in terms of what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention needs not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
