DETAILED DESCRIPTION OF THE INVENTION

[0018] Referring to FIGS. 1 to 3, a copy apparatus 1 of a first embodiment comprises an image processing device 200 and a peripheral device 100. The image processing device 200 comprises a receiving port 210, a processor 220, a storage 230 and an output port 240. The image processing device 200 comprises, for example but without limitation to, a computer, a server or a multi-function peripheral.

[0019] The receiving port 210 receives old image data ID1 and an encoding requirement signal SC from the peripheral device 100. Each of the receiving port 210 and the output port 240 may have the interface, such as the USB interface, the wired or wireless network interface, which can achieve the communication or electrical connection; or an ordinary direct electrical connection interface (direct bonded together or electrically connected together through electrical connectors). The encoding requirement signal SC may comprise executor's identification data, time, copy count and/or information of the peripheral device. The executor's identification data may be obtained through a biometrics sensor or electronic inductor on the peripheral device. The peripheral device 100 comprises, for example but without limitation to, a scanner, a copier or the like.

[0020] The processor 220 electrically connected to the receiving port 210 performs a judging process on the old image data ID1 according to the encoding requirement signal SC. When the processor 220 judges an old information block B1 of the old image data ID1 as containing old copy generation-count information IG1, the processor 220 generates a new information block B2 containing new copy generation-count information IG2 according to the old copy generation-count information IG1. Then, processor 220 subtracts the old information block B1 from the old image data ID1 to obtain a subtracted result and adds the new information block B2 to the subtracted result to generate new image data ID2 and an encoding record CR. The encoding record CR may comprise, for example but without limitation to, the encoding time, the encoding method, the information before encoding, the information after encoding, the information of the encoding requirement signal and the like. The new information block B2 may further comprise the information selected from the group consisting of the user information, the date information and the information of the peripheral device 100.

[0021] The storage 230 electrically connected to the processor 220 stores the encoding record CR. The storage 230 may be implemented by a hard disk drive, an optical disk drive, a magnetic tape drive or the like. In one embodiment, the storage 230 may further store the information selected from the group consisting of the old image data ID1, the encoding requirement signal SC and the new copy generation-count information IG2.

[0022] The output port 240 electrically connected to the processor 220 outputs the new image data ID2. The output port 240 may have the interface, such as the USB interface or the network interface, capable of achieving the electrical connection.

[0023] In one embodiment, the receiving port 210 and the output port 240 may be combined together. In another embodiment, the encoding requirement signal SC may be omitted. That is, the image processing device 200 performs the judging and processing processes upon the receipt of the old image data ID1.

[0024] In this embodiment, the processor 220 further outputs the new image data ID2 through the output port 240 to the peripheral device 100 according to the encoding requirement signal SC. The peripheral device 100 may store or transmit the new image data ID2, or print the new image data ID2 on a medium M.

[0025] The copy generation-count information represents the information that the original has been copied for how many generations. For example, after the original is copied at the first time, a first generation of reproduced document, on which the generation-count information of 1 is recorded, is obtained. A second generation of reproduced document, on which the generation-count information of 2 is recorded, is obtained by copying the first generation of reproduced document, and so on. Thus, the new copy generation-count information IG2 is equal to the old copy generation-count information IG1 plus one predetermined value, which is 1 in this embodiment. In other embodiments, the predetermined value may be any value, such as 2, 3, 4 or the like.

[0026] For example, the old image data ID1 in FIG. 2 contains original image data ID and the old information block B1. The old information block B1 contains the information, such as bar codes corresponding to the human-readable code of 0316062603507, which represents that the copy generation-count is three (03), the copy time falls on Jun. 26, 2016 (160626), the code of the copy requester is (035), and the copy count is seven (07) in order. The new image data ID2 processed by the image processing device 200 of this embodiment contains the original image data ID and the new information block B2. The new information block B2 contains the information of the bar codes corresponding to the human-readable code of 0416062702906, which represents that the copy generation-count is four (04) (representing the reproduced document is copied from the third generation of reproduced document), the copy time falls on Jun. 27, 2016 (160627), the code of the copy requester is (029), and the copy count is six (06) in order.

[0027] It is worth noting that the image processing device 200 and the peripheral device 100 may be implemented separately, and may also be combined into an integrated copy apparatus 1. That is, the image processing device 200 and the peripheral device 100 are mounted in a casing of the copy apparatus 1, wherein the associated data or records may be selected and only stored in the copy apparatus 1, or transmitted to a cloud apparatus through the network. In this case, the copy apparatus 1 comprises the peripheral device 100 and the image processing device 200. The peripheral device 100 scans a document D to obtain the old image data ID1. The image processing device 200 connected to the peripheral device 100 receives the old image data ID1 and the encoding requirement signal SC, and performs the judging process on (or according to) the old image data ID1 according to the encoding requirement signal SC. When the old information block B1 is judged as containing the old copy generation-count information IG1, the new information block B2 containing the new copy generation-count information IG2 is generated according to the old copy generation-count information IG1, and the old information block B1 is subtracted from the old image data ID1 to obtain a subtracted result and the new information block B2 is added to the subtracted result to generate the new image data ID2 and the encoding record CR. Next, the peripheral device 100 further receives the new image data ID2, and prints the new image data ID2 on the medium M to complete the copy process.

[0028] In FIGS. 2 and 3, the old information block B1 is replaced with the new information block B2, and the blocks B1 and B2 are located at the same position. This is beneficial to the judging accuracy of the image processing device 200. In FIG. 4, the old information block B1 is replaced with the new information block B2, but the two blocks B1 and B2 are located at different positions. A reference point P1 of the old information block B1 is offset from a reference point P2 of the new information block B2 by a displacement. The image processing device 200 may also judge the generation count according to the position of the reference point P2. That is, the bar codes may not contain the generation-count information, or the generation-count information is directly replaced with the position of the reference point.

[0029] FIG. 5 is a flow chart showing an image processing method of the copy apparatus according to the first embodiment of this disclosure. First, in step S01, the peripheral device 100 scans the document D to obtain the old image data ID1, and the image processing device 200 receives the old image data ID1 and the encoding requirement signal SC. Next, in step S02, the image processing device 200 performs a judging process on the old image data ID1 according to the encoding requirement signal SC to judge whether the old information block B1 of the old image data ID1 contains the old copy generation-count information IG1 or not. If the judged result of the step S02 is affirmative, then step S03 is performed and the image processing device 200 judges whether the old copy generation-count information IG1 is greater than a threshold value TH. If the judged result of the step S03 is affirmative, then step S05 is executed and the image processing device 200 generates a copy inhibiting signal, to inhibit the new image data ID2 from being generated, and informs the peripheral device of the associated message. If the judged result of the step S03 is negative, then step S06 is executed and the image processing device 200 generates the new information block B2 containing the new copy generation-count information IG2 according to the old copy generation-count information IG1, subtracts the old information block B1 from the old image data ID1 to obtain a subtracted result and adds the new information block B2 to the subtracted result to generate the new image data ID2 and the encoding record CR. Next, step S07 is executed to perform outputting or printing to output the new image data ID2 or print the new image data ID2 on the medium M. If the judged result of the step S02 is negative, then step S04 is performed to generate first generation copy information IG0 and first generation image data ID0 according to the old image data ID1, and the step S07 is continued. That is, when the old copy generation-count information IG1 is absent, the image processing device 200 regards the document to be copied as an original, and adds the copy generation-count information of the first generation to the reproduced document, and generates the first generation image data.

[0030] FIG. 6 is a schematic view showing the copy apparatus according to the second embodiment of this disclosure. As shown in FIG. 6, this embodiment is similar to the first embodiment except for the difference that the new image data ID2 is outputted to a printing device 300 different from the peripheral device 100, and the printing device 300 prints the new image data ID2 on the medium M. In this case, the encoding requirement signal SC may contain the information of specifying the printing device 300.

[0031] FIG. 7 is a schematic view showing a copy system according to the preferred embodiment of this disclosure. The copy method of FIG. 5 may also be applied to the copy system. As shown in FIG. 7, multiple peripheral devices 100 are connected to the image processing device 200, which may be regarded as a cloud server, through a network 400. The copy operation of each peripheral device 100 is controlled and recorded by the image processing device 200 to implement the copy processes with the copy history records in the office or unit. Also, different generations of original image data ID may be compared in the cloud server to immediately judge whether the original image data ID is improperly modified or not, and notify the information office or unit to perform the inspection when the original image data ID is improperly modified.

[0032] With the above-mentioned embodiment of this disclosure, the new copy generation-count information can be generated according to the old copy generation-count information when the original is copied, so that each generation of copied record of the original can be collected in the copied generation-count information to facilitate the subsequent inspection work. In addition, the restriction of the copy generation-count may also effectively control and prevent the poor effect of security or quality caused after the original is copied through too many generations.

[0033] While this disclosure has been described by way of examples and in terms of preferred embodiments, it is to be understood that this disclosure is not limited thereto. To the contrary, it is intended to cover various modifications. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications.
