The present invention relates to a digital data processing device, in particular to a digital data processing device with a plurality of computing cards.

In order to maintain the quality of electronic products, they need to be fully tested before they leave the factory. For example, in order to detect whether the appearance or display picture of the electronic product is normal, the appearance or the display picture of the electronic product is usually photographed first through a photographing device. Next, after the photographing device transmits the obtained image data to the image capture card, the software in the computer analyzes the image data, thereby detecting electronic products. Since there may be many items to be detected, multiple image capture cards are generally used for different image processing in the computer. Therefore, conventionally, the photographing device is first connected to an image splitter, and then the image splitter is connected to a plurality of image capture cards. Here, the number of video capture cards that the video splitter can connect to is related to the number of ports on the video splitter. For example, a video splitter with 2 ports (1 to 2) can be connected to 2 video capture cards .

If the video splitter is to be connected to more video capture cards, a video splitter with more ports needs to be selected. However, video distributors with more ports are very expensive, and the number of video capture cards that can be connected in practice is still very limited, and it is impossible to connect to a large number of video capture cards. Therefore, the industry needs a new digital data processing device, which is not limited by the number of ports of the video distributor, and can still connect a large number of video capture cards.

Please refer to FIG. 1 . FIG. 1 is a three-dimensional schematic diagram of a digital data processing apparatus according to an embodiment of the present invention. As shown in FIG. 1 , the present embodiment discloses a digital data processing device 1 . The digital data processing device 1 includes a circuit board 10 , a computing card 12 a (first computing card), a computing card 12 b (second computing card), and a computing card 12 c (third computing card), and the computing card 12a, the computing card 12b, and the computing card 12c are pluggably coupled to the circuit substrate 10. In practice, the digital data processing device 1 can be a test device or a computer for computing, and a camera (not shown) can be connected to the outside to photograph the appearance or display screen of the electronic product (not shown) to be tested. . In other words, the external photographing device can transmit the captured image data to the digital data processing device 1 via a cable. In one example, each of the computing card 12a, the computing card 12b, and the computing card 12c may be an image capture card, or a module having an image computing function. Here, although FIG. 1 shows three computing cards, in fact, the present embodiment is not limited to three computing cards, for example, two computing cards or more than 4 computing cards are acceptable. In addition, this embodiment does not limit whether the specifications or functions of the computing card 12a, the computing card 12b and the computing card 12c are the same. For example, the computing card 12a, the computing card 12b and the computing card 12c can be respectively used to execute the same or different image processing programs. .

In order to explain the functions of the digital data processing apparatus 1 of this embodiment, please refer to FIG. 1 and FIG. 2 together. FIG. 2 is a functional block diagram of the digital data processing apparatus according to an embodiment of the present invention. As shown in the figure, the computing card 12a has an input unit 1200a (first input unit) and an output unit 1202a (first output unit). The input unit 1200a is used for receiving image data in a first format. In one example, the input unit 1200a can be connected to an externally connected camera device via a cable, and the cable is used to transmit the image data in the first format. For example, the image data in the first format may be an image data transmitted in a low voltage differential signal (LVDS) or other common specifications, as long as the input unit 1200a can receive a signal transmission format conforming to a cable, it belongs to this embodiment category.

In addition, a signal may be transmitted between the output unit 1202a of the computing card 12a and the input unit 1200b of the computing card 12b through a first transmission path, and the first transmission path may be a cable. In one example, if the transmission speed of the internal circuit (eg, the circuit substrate 10 ) is sufficient, the present embodiment can also use the internal circuit of the circuit substrate 10 as the first transmission path, which is not limited herein. Here, because the transmission medium of the image data is different, the image data transmitted between the output unit 1202a and the input unit 1200b is represented by the second format, which is used to explain that the image data output by the output unit 1202a is not necessarily the same as the aforementioned first format. In one example, if the computing cards can support the transmission of signals in the first format, the second format can of course be equal to the first format. In another example, if the computing cards cannot support the transmission of signals in the first format, the second format may be any format commonly used for transmitting image data between computing cards.

In addition, the output unit 1202b of the computing card 12b and the input unit 1200c of the computing card 12c transmit signals via a second transmission path, and the second transmission path may be a cable. In one example, if the transmission speed of the internal circuit (eg, the circuit substrate 10 ) is sufficient, this embodiment can also use the internal circuit of the circuit substrate 10 as the second transmission path, which is not limited herein. Therefore, the computing card 12a, the computing card 12b and the computing card 12c can be regarded as being connected in series, and the image data can be transmitted from the computing card 12a to the computing card 12b and the computing card 12c in sequence. Here, this embodiment does not limit whether the image data is processed when passing through the computing card 12a, the computing card 12b, and the computing card 12c. For example, the computing card 12a and the computing card 12b can only store the received image data without processing, and directly transfer the image data to the computing card 12c, so that the computing card 12a, the computing card 12b and the computing card 12c can obtain the content the same image data. In this way, the purpose of being able to transmit the image data to a plurality of computing cards without the need for an image distributor is achieved.

In order to explain the functions of the computing card 12a, computing card 12b and computing card 12c in this embodiment, please refer to FIG. 2 and FIG. 3 together. FIG. 3 is a functional block diagram of a digital data processing device according to another embodiment of the present invention. . As shown in the figure, in addition to the input unit 1200a and the output unit 1202a, the computing card 12a may also have an image processing unit 1204a (a first image processing unit), which are respectively coupled to the input unit 1200a and the output unit 1202a. Moreover, when the first format is different from the second format, the image processing unit 1204a can convert the image data from the first format to the second format. In addition, the image processing unit 1204a can also process the image data, for example, can perform distortion correction, flat-field correction, pixel shift correction, etc., which is not used in this embodiment. However, the image processing unit 1204a can also perform other algorithms related to image processing.

In one example, if the board card of the computing card 12a has insufficient space, the computing card 12a can also be connected to the sub computing card 120a (the first sub computing card), and the computing card 12a can be regarded as the mother computing card at this time. In practice, the sub-computing card 120a may not only have a sub-image processing unit 1206a (a first sub-image processing unit), but the aforementioned output unit 1202a may also be provided by the sub-computing card 120a. In other words, both the computing card 12a and the sub-computing card 120a can have independent computing functions, and the sub-computing card 120a can be pluggably installed on the computing card 12a and can be regarded as a part of the computing card 12a. Here, the image processing unit 1204a and the sub-image processing unit 1206a can be coupled through a specific port, which is not limited in this embodiment, as long as the image processing unit 1204a and the sub-image processing unit 1206a can transmit image data , which is within the scope disclosed in this embodiment.

On the other hand, this embodiment does not limit the image processing unit 1204a and the sub-image processing unit 1206a to have the same or different functions. For example, the sub-image processing unit 1206a can also perform distortion correction, flat field correction, pixel shift correction or other related image processing. processing algorithm. In addition, the image processing unit 1204a and the sub-image processing unit 1206a can also choose to continue to transmit the processed or unprocessed image data (eg, to the next unit). In one example, the computing card 12b and the computing card 12c may have the same configuration as the computing card 12a. For example, the computing card 12b may have an input unit 1200b, an image processing unit 1204b, and a sub computing card 120b, and the sub computing card 120b may have an output unit 1202b and a sub image processing unit 1206b. For example, the computing card 12c may have an input unit 1200c, an image processing unit 1204c, and a sub computing card 120c, and the sub computing card 120c may have an output unit 1202c and a sub image processing unit 1206c.

As an example of actual operation, the input unit 1200a of the computing card 12a can be connected to an externally connected photographing device by a cable, and receive the image data transmitted by the cable. When the computing card 12a, computing card 12b and computing card 12c want to obtain image data with the same content, the image processing unit 1204a and the sub-image processing unit 1206a of the computing card 12a can only transfer the content of the image data or convert the format of the image data. Then, the output unit 1202a can continue to transmit the above-mentioned image data to the input unit 1200b of the computing card 12b. Likewise, the image processing unit 1204b and the sub-image processing unit 1206b of the computing card 12b can only transfer the content of the image data. Then, the output unit 1202b can continue to transmit the above-mentioned image data to the input unit 1200c of the computing card 12c. In this way, the computing card 12a, the computing card 12b, and the computing card 12c can obtain image data of the same content without an image distributor.

The foregoing embodiment exemplifies an example in which the image data is transmitted from the computing card 12a to the internal sub-computing card 120a, and then the sub-computing card 120a transmits the next computing card 12b, but the invention is not limited to this. For example, image data can only be transferred between sub-computing cards. Please refer to FIG. 4 . FIG. 4 is a functional block diagram of a digital data processing apparatus according to still another embodiment of the present invention. As shown in FIG. 4 , the present embodiment discloses a digital data processing device 2. Similar to the previous embodiment, the digital data processing device 2 may also have a circuit substrate (not shown), a computing card 22a (a first computing card ), computing card 22b (second computing card) and computing card 22c (third computing card), and computing card 22a, computing card 22b and computing card 22c are pluggably coupled to the circuit substrate. In addition, the computing card 22a may have an input unit 2200a (first input unit), an image processing unit 2204a (first image processing unit), and a sub-computing card 220a (first sub-computing card), and the sub-computing card 220a may have a sub-image The processing unit 2206a (the first sub-image processing unit) and the output unit 2202a (the first output unit). In addition, the configuration of the computing card 22b and the computing card 22c may be the same as that of the computing card 22a, which will not be repeated here.

Different from the previous embodiment, the sub-computing card 220a, the sub-computing card 220b, and the sub-computing card 220c may have a sub-input unit 2208a, a sub-input unit 2208b, and a sub-input unit 2208c, respectively. As an example of actual operation, the input unit 2200a of the computing card 22a can use a cable to connect an externally connected photographing device, and receive the image data transmitted by the cable. When the computing card 22a, computing card 22b and computing card 22c want to obtain image data of the same content, the image processing unit 2204a and the sub-image processing unit 2206a of the computing card 22a can only transfer the content of the image data or convert the format of the image data. Next, the output unit 2202a can continue to transmit the above-mentioned image data to the sub-input unit 2208b of the computing card 22b. In other words, the image data is transmitted from the previous sub-computing card to the next sub-computing card. Next, the sub-input unit 2208b of the computing card 22b can transmit the image data to the image processing unit 2204b and the sub-image processing unit 2206b respectively, so that the computing card 22b can obtain the same image data.

Here, the sub-image processing unit 2206b may only transmit the content of the image data, and then continue to transmit the above-mentioned image data to the sub-input unit 2208c of the computing card 22c via the output unit 2202b. It is worth mentioning that because the image processing unit 2204b has been distinguished from the transmission path of the image data, whether the computing card 22c can obtain image data of the same content is not related to the image processing unit 2204b. Therefore, after receiving the image data, the image processing unit 2204b can directly perform any image processing. In this way, the computing card 22a, the computing card 22b, and the computing card 22c can obtain video data of the same content without an image distributor.

To sum up, the digital data processing device provided by the present invention can realize the purpose of connecting and transmitting image data to a plurality of computing cards by connecting a plurality of computing cards to each other in series. Those with ordinary knowledge in the art should understand that under the architecture of the digital data processing device disclosed in the present invention, not only an image distributor is not required, but also a large number of computing cards can be connected in series, thereby breaking through the limitations of traditional image distributors. The number of ports is limited, and it can be used more widely in practice.
