DESCRIPTION OF THE PREFERRED EMBODIMENT
Some sample embodiments of the invention will now be described in greater detail. Nevertheless, it should be recognized that the present invention can be practiced in a wide range of other embodiments besides those explicitly described, and the scope of the present invention is expressly not limited except as specified in the accompanying claims.
According to the conventional image device, either the scanning device or the video device cannot process and integrate the different image types, due to the scanning device or video device being independent image devices within the computer system. Thus, the present invention provides an image device, which can combine the function of scanning and capturing to be a single image device to process the image data from the scanning device or video device.
In the preferred embodiment of the present invention, the image data (digital signal) is outputted by utilizing the common back-end outputting interface to output the image data, which is obtained from the scanning device or video device, after the image data is processed by image data processing elements. The advantage of the common back-end outputting interface is that the connect port can be simplified to provide another device to connect therein.
FIG. 1 is a block diagram for showing the scanning device and a video device that utilizing the common back-end outputting interface to output the image data. Reference number 10A denotes the first image device, such as video device, which can be digital camera. The video device 10A utilized the first lens to capture the image data of the real object as the first image data, and focused on the first photosensor 20A. In the preferred embodiment of the present invention, the first photosensor 20A comprises CMOS (complementary metal-oxide-semiconductor) sensor or CCD (charge coupled device). Next, the first image data is transmitted to the first AFE (analog-front-end) device 30A, wherein the first AFE device 30A is used to convert the first image data into the first digital signal. Then, the first digital signal is transmitted to the first DSP (digital signal process) device 40A to process the first digital signal, wherein the first AFE 30A comprises ADC (analog to digital converting system.)
Furthermore, the present system having a second image device 10B, wherein the second image device 10B is a scanning device. During the scanning process, the scanning light illuminates the scanning document, and the scanning light is transmitted to the scanning device 10B with a second lens from the scanning document. Then, the second photosensor 20B receives the scanning light of the scanning document to obtain a second image data; wherein the second photosensor 20B comprises CMOS sensor or CCD. Thereafter, the second imaged data is transmitted to the second AFE device 30B to convert the second image data from the second analog signal into second digital signal. Next, the second digital signal is transmitted to the second DSP device 40B which processes the second digital signal.
The image data processing elements of the video device 10A and scanning device 10B have the same processing function in the present system. Thus, the video device 10A and scanning device 10B can be integrated to be a single image device to process the different image data type. The difference between the video device 10A and scanning device 10B is that the image data is three-dimensional type for video device 10A, and the two-dimensional type is for scanning device 10B. In order to combine the video device 10A and scanning device 10B, the common back-end outputting interfaces 50 may be used as the outputting interface to output the image data of video device 10A or scanning device 10B to the outputting device (not shown in FIG.). In the present invention, the common back-end outputting interfaces 50 comprise IEEEE 1394, wireless, or USB (universal serial bus).
In another preferred embodiment of the present invention, the image data of the video device 10A or scanning device l0B is processed by the common image data processing elements. FIG. 2 is a block diagram for showing the video device 12A and scanning device 12B that used the common image data processing elements to process the image data. The video device 12A having the first lens and a first photo sensor to capture the image data of the real object as the first image data, and to capture the first image data to the first photosensor within the video device 12A. In addition, during the scanning process, the scanning light source of the scanning device 12B is used to illuminate the scanning document to obtain a second image data. Then, the second image data is transmitted to the second lens, such that the second photosensor can receive the second image data.
Then, the first image data and second image data are communicated into the MUX (multiplexer) 14. The MUX 14 is used to treat the two type image data from the video device 12A and scanning device 12B. In this embodiment, the MUX 14 can treat the two different image data type and output the required imaged data type, for example, the first image data, which is captured by the video device 12A, and the second imaged data, which is scanned by scanning device 12B. Next, the first imaged data or second imaged data is transmitted into the common AFE device 30 to convert the first imaged data from first analog signal into the first digital signal (or second imaged data is converted from second analog signal into the second second digital signal.) Thereafter, the first digital signal (or second digital signal) is transmitted into the DSP device 40 to process the first digital signal (or second digital signal.) Finally, the first digital signal (or second digital signal) is outputted to the outputting device (not shown) by common back-end outputting interface 50.
Furthermore, the MUX 14, common AFE device 30, common DSP device 40, and common back-end outputting interface 50 are common image processing device elements, such that the image data of the video device 12A or scanning device 12B can be processed and output by the image processing elements within a single image device. Thus, either the image data of the real object or scanning object can utilize the common image processing elements to process to reduce the cost.
Moreover, the other preferred embodiment of the present inventions includes a photosensor 20 as the common image data processing element. According to the aforementioned embodiment, the photosensor 20 is independent of the video device 10A and scanning device 10B. The cost of the photosensor 20 is very important in the image device; thus, either the video device 10A or scanning device 10B has photosensor (as shown in FIG. 1 which denotes 20A and 20B) to detect the image data. Thus, the photosensor 20 can be included as the common processing element to detect the imaged light.
Referring to FIG. 3 is a block diagram for showing the video device 10A and scanning device 10B, which utilize the common photosensor 20 to detect the first and second imaged light. The first image device 10A may be a video device having the first lens to capture the first imaged data to the common photosensor 20; similarly, the second image device 10B has the second lens to reflect the second imaged data to the common photosensor 20. When the first and second image lights are captured or reflected to the common photosensor 20 by the video device 10A or scanning device l0B, the common photosensor 20 can treat the different type imaged data and output the required imaged data to the common AFE device 30. Similarly, the common AFE device 30 converts the first imaged data (or second imaged data) from the first analog signal (or second analog signal) to the first digital signal (or second digital signal.) Finally, the first digital signal (or second digital signal) is outputted to the outputting device by common back-end outputting interface 50.
According to abovementioned, the present invention provides an image device to diminish the space and the manufacturing. Furthermore, due to the video device and scanning device having the same processing elements, thus, the scanner and video output device could combine to be an image device.
Although specific embodiments have been illustrated and described, it will be obvious to those skilled in the art that various modifications may be made without departing from what is intended to be limited solely by the appended claims.
