[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.

[0028] The numbers in the flowchart of this application have no size or order, and are only used to distinguish the steps to be described, facilitating a simple and clear description of the technical solution of this application. The technical solution of this application will be described in detail with specific embodiments below. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0029] Figure 1 It is a schematic diagram of the application scenario of this application. As Figure 1 shown, the imaging device 10 is a device capable of forming images or texts on an imaging medium. For example, the imaging device 10 can be a printer, a copier, a fax machine, a scanner, or a multifunctional all-in-one machine integrating functions such as printing, copying, faxing, and scanning. The imaging device 10 can specifically form images by means of laser printing or inkjet printing, etc. The specific implementation and printing method of the imaging device 10 in the embodiments of this application are not limited.

[0030] The imaging device 10 can be connected with at least one imaging cartridge, and each imaging cartridge can be used to provide the materials required for the imaging device 10 to form an image. For example, in Figure 1 the example shown, the imaging device 10 is connected with a total of 4 imaging cartridges, namely imaging cartridge 21, imaging cartridge 22, imaging cartridge 23, and imaging cartridge 24. Specifically, as Figure 1 shown, the 4 imaging cartridges can be imaging cartridges of four colors, namely K / C / M / Y (Black / Cyan / Magenta / Yellow).

[0031] Figure 2 It is a schematic diagram of the imaging device chip and the imaging cartridge chip. As Figure 2As shown in the figure, the imaging device 10 includes an imaging device chip 101 and a serial bus 100. Among them, the imaging device chip 101 can be used to control other circuits in the imaging device 10 and manage the imaging cartridge connected to the imaging device 10, etc. For example, the imaging device chip 101 can be any one of a controller of the imaging device 10, a central processing unit (CPU), other general-purpose processors, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate and transistor logic devices, etc. The imaging device chip 101 is connected to the serial bus 100.

[0032] Each imaging cartridge includes an imaging cartridge chip. Among them, the imaging cartridge chip can be used to record initial information of the corresponding imaging cartridge, such as model, color, recording material capacity, production date, and manufacturer code, and imaging auxiliary information such as data representing the remaining / consumed amount of the recording material, and can play a role in identifying the imaging cartridge and providing the usage status of the recording material. For example, the imaging cartridge chip can be any one of a controller, a central processing unit (CPU), other general-purpose processors, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate and transistor logic devices, etc.

[0033] In Figure 1 In the example shown, imaging cartridge 21 includes imaging cartridge chip 211, imaging cartridge 22 includes imaging cartridge chip 221, imaging cartridge 23 includes imaging cartridge chip 231, and imaging cartridge 24 includes imaging cartridge chip 241. The imaging cartridge chip of each imaging cartridge is connected to the serial bus 100 of the imaging device 10, so that the imaging device chip 101 can transmit data with the imaging cartridge chip 211 of each imaging cartridge through the serial bus 100. The imaging device 10 can perform processing such as control and authentication of the imaging cartridge through the transmitted data.

[0034] When the materials such as ink and toner filled in the imaging cartridge connected to the imaging device 10 are used up, the user can remove the imaging cartridge from the imaging device 10, and then install a new imaging cartridge and connect it to the imaging device 10, so that the imaging device 10 can continue to form an image according to the materials provided by the new imaging cartridge.

[0035] Accordingly, the imaging device 10 needs to authenticate the newly installed imaging cartridge by the user, so as to manage the imaging cartridge. For example, Figure 3 FIG. is a schematic flowchart of the authentication between an imaging device and an imaging cartridge. As Figure 3 shown, the method can be applied to the scenario shown in Figure 1 and is executed by the imaging device 10 and any imaging cartridge. As Figure 3 shown in the example, taking the imaging device 10 authenticating the connected imaging cartridge 21 as an example for illustration, it can be understood that the imaging cartridge 21 can also be other imaging cartridges connected to the imaging device 10.

[0036] As Figure 3 shown, when the imaging cartridge 21 is installed in the imaging device 10 and the imaging cartridge chip 211 is connected to the imaging device chip 101, in S101, the imaging cartridge chip 211 will first perform a first authentication process on the imaging cartridge 21 with the imaging device chip 101. Among them, the first authentication process can also be called a shallow authentication process. After detecting that the first imaging cartridge 20 is installed in the imaging device 10, the imaging device chip 101 can send the indication information of the first authentication process to the imaging cartridge chip 211, so that the imaging device chip 101 and the imaging cartridge chip 211 send the data corresponding to the first authentication process to each other, etc., so as to realize the first authentication process of the imaging device 10 for the imaging cartridge 21.

[0037] In one embodiment, the first authentication process includes confirming the existence of the imaging cartridge, reading the imaging cartridge information, reading the serial number seed (verification data associated with the serial number), verifying the serial number seed, and reading the digital signature data, etc.

[0038] Subsequently, when the imaging cartridge 21 passes the first authentication process, in S102, the imaging cartridge chip 211 and the imaging device chip 101 continue to perform a second authentication process on the imaging cartridge 21. Among them, the second authentication process can also be called a deep authentication process. The imaging device chip 101 can send the indication information of the second authentication process to the imaging cartridge chip 211, so that the imaging device chip 101 and the imaging cartridge chip 211 send the data corresponding to the second authentication process to each other, etc., so as to realize the second authentication process of the imaging device 10 for the imaging cartridge 21.

[0039] In one embodiment, the second authentication process includes performing deep encryption communication between the imaging cartridge chip 211 and the imaging device chip 101, etc.

[0040] Finally, when the imaging cartridge 21 passes the second authentication process, in S103, the imaging device chip 101 can use the materials provided by the imaging cartridge 21 to control the relevant circuits in the imaging device 10 to perform the imaging process.

[0041] In some cases, some imaging devices 10 are configured to be able to authenticate only imaging cartridges with unique serial numbers to ensure the uniqueness of the imaging cartridges. Therefore, after the user installs a new compatible imaging cartridge into the imaging device 10, if the serial number of the compatible imaging cartridge is the same as the serial number of the previously installed imaging cartridge, the imaging device 10 will not continue to authenticate the imaging cartridge, resulting in the inability to use the installed compatible imaging cartridge, thus increasing the printing cost of the imaging device 10.

[0042] Therefore, if the imaging cartridge chip 211 of some imaging cartridges determines that the second authentication process has not been performed after a preset time when the imaging cartridge has passed the first authentication process, the imaging cartridge chip 211 can ensure the smooth use of the imaging cartridge by switching the authentication data.

[0043] For example, Figure 4 is a schematic diagram of the authentication process between another imaging device and an imaging cartridge. As Figure 4 shown in the embodiment, when the imaging cartridge chip 211 of the imaging cartridge 21 determines that the imaging cartridge 21 has passed the first authentication process in S101 and the waiting time for the second authentication process exceeds the preset value T and the second authentication process has still not been performed, it means that the serial number of the imaging cartridge 21 is unavailable, resulting in the inability of the imaging device 10 to perform the second authentication process on the imaging cartridge 21 based on the current authentication data of the imaging cartridge 21. Therefore, the imaging cartridge chip 211 switches the authentication data of the imaging cartridge 21 through S1010. In this embodiment, the authentication data may specifically include the serial number of the imaging cartridge 21. Multiple serial numbers can be stored in the imaging cartridge chip 211 for switching. Subsequently, in S1020, the imaging device 10 re-performs the first authentication process on the imaging cartridge 21 after switching the authentication data, and in S102, the imaging device 10 performs the second authentication process on the imaging cartridge 21. When the imaging cartridge 21 passes the second process, the imaging device chip 101 can use the materials provided by the imaging cartridge 21 to control the relevant circuits in the imaging device 10 to perform the imaging process.

[0044] In one embodiment, when multiple imaging cartridges are installed in the imaging device 10, the imaging device 10 first performs the first authentication process on all imaging cartridges respectively, and after all imaging cartridges have passed the first authentication process, then performs the second authentication process on all imaging cartridges respectively. Specifically, for Figure 4In the imaging cartridge 21 in the illustrated embodiment, when the imaging cartridge chip 211 determines that the imaging cartridge 21 has passed the first authentication process in S101, if the imaging device 10 fails to perform the second authentication process on the imaging cartridge 21 after a preset time due to other imaging cartridges, the imaging cartridge chip 211 will still execute the step of switching authentication data in S1010 after the waiting time exceeds the preset value T, resulting in a waste of authentication data and affecting the authentication efficiency of the imaging cartridge 21.

[0045] Based on the above technical problem of wasting authentication data when authenticating an imaging cartridge, the present application provides an imaging cartridge and an imaging cartridge chip, enabling the imaging cartridge chip of the imaging cartridge to determine whether to switch the authentication data of the imaging cartridge at least according to a communication record table, thereby avoiding the ineffective switching of the authentication data by the imaging cartridge chip and reducing the waste of authentication data. The technical solution of the present application will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0046] Figure 5 It is a schematic flowchart of a control method executed by an imaging cartridge chip provided by the present application, as Figure 5 The method executed by the illustrated imaging cartridge chip can be applied to a scenario as Figure 2 shown, and is executed by the imaging device chip 101 of the imaging device 10 and the imaging cartridge chip 211 of the imaging cartridge 21. As Figure 5 shown in the example, the authentication of the connected imaging cartridge 21 by the imaging device 10 is taken as an example for illustration. It can be understood that this method can also be applied to other imaging cartridges connected to the imaging device 10. Specifically, as Figure 5 shown, the control method executed by the imaging cartridge chip includes:

[0047] S100: The imaging cartridge 21 is loaded into the imaging device 10.

[0048] Specifically, a user of the imaging device 10 can load the imaging cartridge 21 into the imaging device 10, enabling the imaging cartridge chip 211 of the imaging cartridge 21 to be connected to the imaging device chip 101 through the serial bus 100 of the imaging device 10, and the imaging device chip 101 can detect and determine that the imaging cartridge 21 is loaded into the imaging device 10 through the serial bus 100.

[0049] S101: The imaging device 10 performs a first authentication process on the imaging cartridge 21.

[0050] Specifically, after the imaging cartridge 21 is installed in the imaging device 10, the imaging device chip 101 can send indication information of the first authentication process to the imaging cartridge chip 211, so that the imaging device chip 101 and the imaging cartridge chip 211 send data corresponding to the first authentication process to each other, thereby implementing the first authentication process of the imaging device 10 for the imaging cartridge 21.

[0051] In one embodiment, when the imaging device 10 performs the first authentication process on the imaging cartridge 21, it includes the imaging cartridge chip 211 sending authentication data to the imaging device chip 101. Among them, the authentication data is used to determine whether to perform a second authentication process on the imaging cartridge 21. In a specific implementation manner, the authentication data may include the serial number of the imaging cartridge 21.

[0052] S1001. The imaging cartridge chip determines whether to switch the authentication data at least according to the communication record table.

[0053] Specifically, Figure 7 is a schematic structural diagram of an imaging cartridge chip provided by this application. As Figure 7 shown, the imaging cartridge chip 211 includes a processing module 2110 and a storage module 2111. Among them, the storage module 2111 is used to store the communication record table.

[0054] In one embodiment, the communication record table is used to record the communication data between each imaging cartridge chip and the imaging device chip 101 among all the imaging cartridge chips connected to the serial bus 100. Through the communication data recorded in the communication record table, it can be determined whether each imaging cartridge chip performs the first authentication process with the imaging device chip 101, and whether it passes the first authentication process. Therefore, the imaging cartridge chip 211 of the imaging cartridge 21 can not only determine whether the imaging cartridge 21 passes the first authentication process through the communication record table, but also determine whether the imaging cartridges 22, 23, and 24 pass the first authentication process.

[0055] In one embodiment, the communication record table may be in the form of Table 1 below. The communication record table includes multiple indication information, and each indication information is used to record whether each imaging cartridge chip transmits communication data for the first authentication process with the imaging device chip 101.

[0056] Table 1

[0057] Imaging Cartridge 21 Imaging Cartridge 22 Imaging Cartridge 23 Imaging Cartridge 24 Whether to Transmit Communication Data Yes / No Yes / No Yes / No Yes / No

[0058] For example, as shown in Table 1, after the imaging cartridge 21 transmits the communication data corresponding to the first authentication process, the imaging cartridge chip 211 of the imaging cartridge 21 can mark the indication information corresponding to the imaging cartridge 21 in Table 1 as "Yes". Similarly, when the imaging cartridge chip 211 of the imaging cartridge 21 determines that the imaging cartridge chips of other imaging cartridges 22, 23, and 24 and the imaging device chip 101 transmit the communication data for the first authentication process, the indication information corresponding to the imaging cartridges 22, 23, and 24 can be marked as "Yes".

[0059] In one embodiment, since the imaging cartridge chips of each imaging cartridge transmit the communication data for the first authentication process to the imaging device chip 101 through the serial bus 100. Therefore, the imaging cartridge chip 211 of the imaging cartridge 21 can obtain the communication data of other imaging cartridges during the first authentication process through the serial bus 100 and record it in the communication record table shown in Table 1, so as to determine whether each imaging cartridge passes the first authentication process according to the indication information corresponding to each imaging cartridge in the communication record table.

[0060] In one embodiment, the communication data shown in Table 1 can specifically be low-level data with a duration of N milliseconds, and N can be 80. Taking the imaging cartridge 21 as an example, after the imaging cartridge 21 passes the first authentication process, the imaging cartridge chip 211 sends low-level data to the serial bus 100. Similarly, the imaging cartridge chip 211 can receive the low-level data sent by the imaging cartridge chips of other imaging cartridges. Then, when receiving the low-level data sent by other imaging cartridge chips on the serial bus 100, it can be determined that the imaging cartridge that sent the low-level data passes the first authentication process.

[0061] In one embodiment, the communication data for the first authentication process transmitted by each imaging cartridge to the imaging device chip 101 through the serial bus 100 includes the identification information of the imaging cartridge, and the identification information can be an ID, etc. After the imaging cartridge chip 211 of the imaging cartridge 21 obtains the communication data during the first authentication process through the serial bus 100, it can determine which imaging cartridge the communication data specifically belongs to according to the identification information in the communication data.

[0062] In one embodiment, the imaging cartridge chip 211 can mark each imaging cartridge through the identification information (ID), etc. of the imaging cartridge chips of the imaging cartridges 21, 22, 23, and 24 on the serial bus. For example, the identification information of the imaging cartridges 21, 22, 23, and 24 is 0x60, 0x62, 0x64, and 0x66 respectively.

[0063] In one embodiment, the communication record table specifically includes a response instruction, an encryption seed instruction, an encryption data instruction, and a specified instruction.

[0064] Table 2

[0065] Imaging Cartridge 21 Imaging Cartridge 22 Imaging Cartridge 23 Imaging Cartridge 24 Whether There is a Response Instruction Yes / No Yes / No Yes / No Yes / No Whether There is an Encryption Seed Instruction Yes / No Yes / No Yes / No Yes / No Whether There is an Encryption Data Instruction Yes / No Yes / No Yes / No Yes / No Whether There is a Specified Instruction Yes / No Yes / No Yes / No Yes / No

[0066] Among them, the response instruction is sent by the imaging cartridge chip to the imaging device chip 101 after the imaging cartridge is loaded into the imaging device 10. The encrypted seed record information is sent by the imaging device chip 101 and is used to indicate the seed used for encryption between the imaging cartridge chip and the imaging device chip 101. The encrypted data record information is the encrypted data transmitted between the imaging cartridge chip and the imaging device chip 101 after receiving the encrypted seed record information. The specified instruction information is sent by the imaging cartridge chip after the imaging cartridge passes the first authentication process. The specified instruction information can be a pull-down instruction with a duration of N ms or an instruction with a relatively long length in the send instruction, etc.

[0067] Therefore, when the indication information corresponding to each imaging cartridge in the communication record table is "yes", it indicates that all the communication data required for the first authentication process has been transmitted between the imaging cartridge chip and the imaging device chip 101, which also indicates that the imaging cartridge corresponding to the imaging cartridge chip has passed the first authentication process. For example, if the indication information of the four instructions corresponding to the imaging cartridge 21 is "yes, yes, yes, yes" respectively, it can be determined according to the communication record table that the imaging cartridge 21 has passed the first authentication process. If the indication information of the four instructions corresponding to the imaging cartridge 22 is "yes, yes, yes, no" respectively, it can be determined according to the communication record table that the imaging cartridge 22 has not passed the first authentication process.

[0068] The storage module 2111 of the imaging cartridge chip 211 provided by the embodiment of the present application is further used to store at least two authentication data of the imaging cartridge 21. Among them, the authentication data may specifically include the serial number corresponding to the imaging cartridge 211. Figure 7 In the example shown, taking the storage module 2111 storing N authentication data as an example, it is denoted as authentication data 1, authentication data 2... authentication data N.

[0069] The processing module 2110 of the imaging cartridge chip 211 can read the authentication data stored in the storage module 2111 and use one of the authentication data to perform the first authentication process and / or the second authentication process on the imaging cartridge 21 with the imaging device chip.

[0070] Such as Figure 5 shown, when the imaging cartridge chip 211 performs the first authentication process on the imaging cartridge 21 with the imaging device chip 101 in S101 and passes the authentication, the imaging cartridge chip 211 starts to wait for the second authentication process on the imaging cartridge 21 with the imaging device chip 101.

[0071] Combined with Figure 7As shown, the processing module 2110 of the imaging cartridge chip 211 can use an authentication data stored in the storage module 2111 to perform a first authentication process on the imaging cartridge 21 with the imaging device chip. After the imaging cartridge 21 passes the first authentication process, the processing module 2110 waits to use the authentication data to perform a second authentication process on the imaging cartridge 21 with the imaging device chip.

[0072] In one embodiment, in S1001 as shown in Figure 5 when the imaging cartridge 21 passes the first authentication process, the processing module 2110 of the imaging cartridge chip 211 does not directly switch the authentication data, but determines whether to switch the authentication data used in the authentication process of the imaging cartridge 21 at least according to the communication record table stored in the storage module 2111.

[0073] In another embodiment, the processing module 2110 also records the waiting time after the imaging cartridge 21 passes the first authentication process. Then in S1001 as shown in Figure 5 when the imaging cartridge 21 passes the first authentication process, it determines whether to switch the authentication data used in the authentication process of the imaging cartridge 21 according to the communication record table and the waiting time stored in the storage module 2111. Specifically, when the waiting time after the imaging cartridge 21 passes the first authentication process is greater than the preset value T, the processing module 2110 of the imaging cartridge chip 211 does not directly switch the authentication data, but determines whether to switch the authentication data used in the authentication process of the imaging cartridge 21 according to the communication record table stored in the storage module 2111.

[0074] In one embodiment, when the waiting time after the imaging cartridge 21 passes the first authentication process is greater than the preset value T, the processing module 2110 of the imaging cartridge chip 211 first obtains the communication record table from the storage module 2111, and then determines whether the imaging cartridges corresponding to the other imaging cartridge chips connected to the serial bus 100 of the imaging device 10 pass the first authentication process according to the communication record table.

[0075] In one embodiment, referring to Figure 5 when the waiting time after the imaging cartridge 21 passes the first authentication process is greater than the preset value T and the imaging cartridges corresponding to the other imaging cartridge chips do not all pass the first authentication process, the processing module 2110 of the imaging cartridge chip 211 determines not to switch the authentication data used in the authentication process of the imaging cartridge 21 in S1002.

[0076] Figure 6 It is a schematic flowchart of a control method executed by another imaging cartridge chip provided by the present application. In another embodiment, referring to Figure 6When the waiting time after the imaging cartridge 21 passes the first authentication process is greater than the preset value T and all the imaging cartridges corresponding to other imaging cartridge chips have passed the first authentication process, the processing module 2110 of the imaging cartridge chip 211 determines the authentication data used when switching the imaging cartridge 21 for the authentication process in S1003.

[0077] Reference Figure 6 Suppose the processing module 2110 of the imaging cartridge chip 211 uses the authentication data 1 stored in the storage module 2111 to perform the first authentication process on the imaging cartridge 21 with the imaging device chip 101, and the imaging cartridge 21 passes the first authentication process. Subsequently, when the waiting time after the imaging cartridge 21 passes the first authentication process is greater than the preset value T, assume that the processing module 2110 of the imaging cartridge chip 211 determines that all the imaging cartridges (imaging cartridge 22, imaging cartridge 23, and imaging cartridge 24) corresponding to other imaging cartridge chips have passed the first authentication process according to the communication record table stored in the storage module 2111. Then, the processing module 2110 of the imaging cartridge chip 211 determines the authentication data used when switching the imaging cartridge 21 for the authentication process. For example, the processing module 2110 can obtain the authentication data 2 from the storage module 2111 and switch the authentication data used when performing the authentication process on the imaging cartridge 21 from the authentication data 1 to the authentication data 2.

[0078] In summary, in the imaging cartridge chip 211 provided in this application, the processing module 2111 can determine whether to switch the authentication data used when performing the authentication process on the imaging cartridge 21 according to the communication record table stored in the storage module 2110 and the waiting time after the imaging cartridge 21 passes the first authentication process. Compared with Figure 4 directly switching the authentication data according to the waiting time after the imaging cartridge 21 passes the first authentication process as shown, when the imaging device 10 does not perform the second authentication process on the imaging cartridge 21 after the preset time due to other imaging cartridges, it can avoid invalid switching of the authentication data of the imaging cartridge 21 and reduce the waste of authentication data.

[0079] It can be understood that when the waiting time after the imaging box 21 passes the first authentication process is greater than the preset value T, and the other imaging boxes have passed the first authentication process, the reason why the imaging device 10 has not yet performed the second authentication process on the imaging box is that the authentication data of the current imaging box 21 is not available. Therefore, the imaging box chip 211 can switch the authentication data used when performing the authentication process on the imaging box 21, so that the imaging device 10 performs the first authentication process and the second process on the imaging box 21 according to the switched authentication data. When the waiting time after the imaging box 21 passes the first authentication process is greater than the preset value T, and the other imaging boxes have not all passed the first authentication process, the reason why the imaging device 10 has not yet performed the second authentication process on the imaging box is that the other imaging boxes have not passed the first authentication process. Therefore, the imaging box chip 211 does not switch the authentication data used when performing the authentication process on the imaging box 21, but continues to wait for the other imaging box chips 211 to pass the first authentication process by switching the authentication data, and then the imaging device 10 performs the second authentication process on all the imaging boxes after all the imaging boxes pass the first authentication process.

[0080] In summary, the imaging box chip provided by this embodiment can more effectively determine that the second authentication process has not been performed due to the current imaging box 21, thereby switching the authentication data of the imaging box 21 based on more accurate conditions, thereby ensuring the validity of the switched authentication data, and ensuring as much as possible that the imaging box chip 211 can pass the first authentication process and the second authentication process according to the switched authentication data, so as to improve the authentication efficiency of the imaging box 21.

[0081] In one embodiment, Figure 6 In the illustrated embodiment, after the processing module 2111 of the imaging box chip 211 switches the authentication data in S1003, in S1020, the processing module 2111 of the imaging box chip 211 also uses the switched authentication data to re-perform the first authentication process on the imaging box 21 with the imaging device chip 101.

[0082] It can be understood that if the imaging box 21 passes the first authentication process in S1020, and since the other imaging boxes have also passed the first authentication process, in S102 after S1020, the processing module 2111 of the imaging box chip 211 can use the switched authentication data to perform a second authentication process on the imaging box 21 with the imaging device chip 101.

[0083] If the imaging cartridge 21 fails the first authentication process in S102, the processing module 2111 of the imaging cartridge chip 211 can continue to execute the steps of switching authentication data in S1001 - S1003, and loop through S1001 - S1020 until the processing module 2111 of the imaging cartridge chip 211 passes the first authentication process for the imaging cartridge 21 using the switched authentication data. Subsequently, in S102, the imaging cartridge chip 211 and the imaging device chip 101 perform a second authentication process on the imaging cartridge 21. Subsequently, in S102, the imaging device chip 101 can use the materials provided by the imaging cartridge 21 to control the relevant circuits in the imaging device 10 to perform an imaging process.
