Description

Technical Field

[0001] The present application relates to a technical field related to color correction in an image forming process, and in particular to a color correction method and apparatus, an image forming device, and a computer-readable storage medium. Background Art

[0002] The characteristics of the imaging components of an image forming device will change with changes in the environmental conditions, number of jobs, replacement of consumables, etc. of the body. Therefore, changes in environmental conditions, number of jobs, replacement of consumables, etc. in color image forming devices are usually used as factors to trigger color correction. That is, when the aforementioned changes will affect the image quality, it is necessary to perform a color correction to automatically adjust the image formation-related parameters to adapt to the current environment.

[0003] Many color image forming devices will quantify each change and participate in the calculation of the printing parameter algorithm. Therefore, the printing parameters calculated by different variables will also be different, so the stability and accuracy of each variable detection device are required to be high. However, as a real-time detection device, it is inevitable that abnormal situations will occur. In abnormal situations, the image forming device will usually continuously trigger color correction, resulting in an increase in the number of color corrections. At the same time, abnormal parameters are involved in color correction calculations, and the correction quality cannot be guaranteed.

[0004] Therefore, a color correction method is needed to avoid continuous triggering of color correction of an image forming device and to improve the quality of color correction so as to enhance user experience and improve user satisfaction. Summary of the invention

[0005] In order to avoid the problem of how to avoid continuous triggering of color correction of an image forming device, resulting in color correction abnormalities, abnormal parameters participating in color correction calculations, and the inability to ensure color correction quality, the present application provides a color correction method and device, an image forming device, and the present application also provides a computer-readable storage medium.

[0006] The present application embodiment adopts the following technical solutions:

[0007] In a first aspect, a color correction method is performed in an image forming device, the method comprising:

[0008] Obtaining a first parameter value, and if the first parameter value exceeds a first set threshold, continuing to determine a first color correction mode associated with the first parameter value, wherein the first parameter value quantitatively represents a condition related to triggering the image forming device to perform automatic color correction, and the first set threshold represents a rated range within which an original source of the first parameter value normally operates;

[0009] If the first color correction mode includes an automatic mode, the automatic mode of the first color correction mode is disconnected.

[0010] In an implementation manner of the first aspect, the first parameter value includes at least one parameter, and the first set threshold is a set of parameter ranges corresponding to the first parameter value.

[0011] According to the method of the embodiment of the present application, the first parameter value is compared with the first set threshold to determine whether the original source of the first parameter value is in a normal working state. If it is abnormal and the current color correction mode is automatic, it is switched to the manual color correction mode to avoid continuous triggering of color correction.

[0012] In an implementation of the first aspect, if the first parameter value is within the first set threshold value and the first parameter value exceeds a second set threshold value, an endpoint value of the second set threshold value close to the first parameter value is used as a variable for calculating a correction parameter in a current color correction mode;

[0013] The second set threshold value is a parameter setting range that indicates that the original source of the first parameter value satisfies the normal working state of the image forming device;

[0014] The second set threshold range is smaller than or equal to the first set threshold.

[0015] According to the method of the embodiment of the present application, by comparing the first parameter value with the second set threshold value, a relatively accurate variable of the color calculation correction parameter is obtained to ensure the quality of color correction.

[0016] In an implementation manner of the first aspect, if the first parameter value is within the second set threshold, the first parameter value is used as a variable for calculating a correction parameter in a current color correction mode.

[0017] In an implementation of the first aspect, if the first parameter value exceeds a first set threshold, a conventional value is introduced as a variable for calculating the correction parameter in the current color correction mode; the conventional value is a parameter value that satisfies a normal working state.

[0018] According to the method of the embodiment of the present application, when the original source of the first parameter value works abnormally, the conventional value is used to participate in the color correction calculation, which can ensure that the color correction quality is in a normal state.

[0019] In an implementation manner of the first aspect, the original source of the first parameter value is used to directly obtain the current parameter of the triggering color correction factor.

[0020] In an implementation manner of the first aspect, an original source of the first parameter value is a detection component or a measurement component.

[0021] In a second aspect, the present application provides a color correction processing device executed in an image forming device, the color correction device comprising:

[0022] A collection module, used for collecting and transmitting the first parameter value, wherein the collection module at least includes an original source of the first parameter value and a transmission source for assisting the original source in obtaining the first parameter value;

[0023] a judgment module, which compares the first parameter value sent by the acquisition module with the first set threshold value, and if the first parameter value exceeds the first set threshold value, continues to judge a first color correction mode associated with the first parameter value, and if the first color correction mode includes an automatic mode, generates a first instruction to disconnect the automatic mode of the first color correction mode;

[0024] Synchronously comparing the first parameter value with a second set threshold value, and if the first parameter value is within the first set threshold value and exceeds the second set threshold value, generating a second instruction that uses the second set threshold value close to the endpoint value of the first parameter value as a variable for calculating a correction parameter in a current color correction mode;

[0025] and / or, if the first parameter value is within the second set threshold, generating a third instruction for using the first parameter value as a variable for calculating a correction parameter in the current color correction mode;

[0026] An updating module receives the first instruction, the second instruction and / or the third instruction of the judging module, and updates a mode for executing color correction and a variable for calculating correction parameters of the color correction mode;

[0027] An execution module, used for executing color correction;

[0028] Wherein, during the process of processing the printing job, the color correction device triggers the image forming device to execute the method steps as described in any one of the first aspect and the various implementation methods of the first aspect.

[0029] According to the color correction device of the embodiment of the present application, the acquisition module collects the first parameter value in real time, and the judgment module makes a real-time judgment on the first parameter value each time. When it is found that the first parameter value exceeds the first set threshold, the color correction mode is switched to manual in time, and the variable values ​​involved in the color calculation correction parameters are changed to avoid multiple triggering of automatic color correction due to abnormalities in the original source, which affects the accuracy of color correction.

[0030] In a third aspect, the present application provides an image forming device, comprising a memory for storing computer program instructions and a processing device for executing computer program instructions, wherein when the computer program instructions are executed by the processing device, the image forming device is triggered to execute the method steps as described in any one of the first aspect and the various embodiments of the first aspect.

[0038] In order to better list the technical solutions of the present application and make the technical solutions and advantages clearer, the technical solutions of the present application will be clearly and completely described in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0039] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. For example: an image forming device is a device that prints images or text on an imaging medium, such as a printer, a copier, a scanner, a fax machine, etc. Since a color image forming device has multiple image forming units, and forms images of various colors by using image forming units and then transfers the images to an intermediate transfer component or a recording material in an overlapping manner to form a multi-color image, it is easy for multiple colors to shift when forming a multi-color image, resulting in a mismatch in the relative positions of the images formed by the image forming units. Therefore, in order to ensure the quality of image formation, the image forming device often needs to perform some color correction. Taking an image forming device with four colors of toner, black K, magenta M, cyan C and yellow Y, as an example, when performing color correction, it is necessary to perform toner concentration detection and image position offset detection. To ensure that the quality of the formed image meets the requirements. As long as it is a device and method that can achieve color correction, it is included in the actual protection scope of the image forming device, regardless of the specific naming name.

[0040] In the embodiment of the present application, the image forming device refers to a printer. The characteristics of the imaging components of the printer will change with the temperature environment. In a color printer, temperature is usually used as a factor to trigger color correction. Since the influence of temperature on the characteristics of the imaging components is more obvious, the temperature value is usually collected by a temperature / temperature and humidity sensor, and the collected temperature value is directly used in the correction trigger condition judgment and printing parameter calculation.

[0041] Therefore, we take temperature as an example to explain the impact of temperature conditions on the printer imaging components. That is, when the temperature change affects the image quality, a color correction needs to be performed to automatically adjust the printing-related parameters to adapt to the current environment.

[0042] In the scenario of one embodiment of the present application, the color printer will involve the current measured ambient temperature value in the calculation of the printing parameter algorithm, for example: the DMAX concentration adjustment algorithm adjusts the high-voltage parameters of the developer, which largely determines the density parameters of the toner. The function that also uses the temperature value to participate in the calculation is the Gamma algorithm, which is mainly used to adjust the color scale during printing. The previous two algorithms use temperature values. The printing parameters calculated by different temperature values ​​will also be quite different. The printing parameters here are the parameters used in the color correction calculation. Usually, the temperature value is directly used to calculate the printing parameters, and other printing parameters can also calculate the difference (topmargin parameter). The principle is to use the temperature value saved when the last color calibration was executed, and the temperature value obtained during the current printing, respectively, to perform a mapping relationship of a point number, and make a difference calculation for the two mapped points. The larger the temperature value difference, the larger the final adjusted point value, and the larger the position of the corresponding color block is adjusted. The calculated difference is mainly used in the adjustment of the color block in the upper and lower directions of color correction. . Therefore, to ensure the stability and reliability of printing parameters, strict requirements are imposed on the stability and accuracy of temperature detection. The stability of temperature detection is guaranteed by the hardware circuit design of the printer. However, when the detection frequency is high (such as real-time monitoring), the circuit will age and be damaged quickly, causing the sensor to detect abnormally. When the temperature detection accuracy is abnormal, the collected temperature value will usually be very different from the true value, such as +999℃. The difference between it and the true value is difficult to control. If the difference is large, the calculated printing parameters will be very different from the calculated printing parameters based on the true value, which will directly lead to poor printing results.

[0043] like Figure 1 As shown, in an embodiment of the present application, a color correction device executed in an image forming device is provided, which mainly includes an acquisition module 101 for acquiring and transmitting a first parameter value. The acquisition module 101 at least includes an original source of the first parameter value and a transmission source that assists the original source in obtaining the first parameter value. Here, the original source is a sensor corresponding to the first parameter value collected. The sensor includes many types, and the IDC sensor used for IDC temperature detection, that is, the IDC temperature sensor, because temperature detection has a great influence on the judgment of the correction trigger condition, the first parameter value in this embodiment is the temperature value detected by the IDC temperature sensor.

[0044] The judgment module 102 compares the first parameter value sent by the acquisition module with the first set threshold value. If the first parameter value exceeds the first set threshold value, the judgment module continues to judge the first color correction mode associated with the first parameter value. If the first color correction mode includes an automatic mode, a first instruction to disconnect the automatic mode of the first color correction mode is generated; when the first parameter value is the temperature value detected by the IDC temperature sensor, the first set threshold value is the acquisition range of the IDC temperature sensor (-40℃~125℃). At this time, if the temperature value detected by the IDC temperature sensor exceeds the acquisition range of the IDC temperature sensor (-40℃~125℃), it is judged that the current IDC temperature sensor is in an abnormal working state, and when the current color correction mode is automatic, the judgment module generates a first instruction to switch the current color correction mode to manual mode.

[0045] An updating module 103 receives the first instruction, the second instruction and / or the third instruction of the judging module, and updates the mode for executing color correction and the variables for calculating correction parameters of the color correction mode;

[0046] The execution module 104 is used to execute color correction.

[0047] In one embodiment of the present application, the judgment module executes a judgment that the current IDC temperature sensor is in an abnormal working state, and at the same time, synchronously compares the first parameter value and the second set threshold value. If the first parameter value is within the first set threshold value and the first parameter value exceeds the second set threshold value, a second instruction is generated to use the endpoint value of the second set threshold value close to the first parameter value as a variable for calculating the correction parameter of the current color correction mode; according to the first parameter value being the temperature value detected by the IDC temperature sensor, the second set threshold value in this embodiment is the effective operating temperature range of the printer (-10℃~40℃), then the temperature value detected by the IDC temperature sensor is between -10℃~-40℃, -10℃ is used as a trigger condition and participates in the calculation of the printing parameters, and similarly, the temperature value detected by the IDC temperature sensor is between 40℃~125℃, 40℃ is used as a trigger condition and participates in the calculation of the printing parameters.

[0048] And / or, if the first parameter value is within the second set threshold, a third instruction is generated to use the first parameter value as a variable for calculating the correction parameters of the current color correction mode; that is, if the temperature value detected by the IDC temperature sensor is between -10°C and 40°C, the temperature value is directly used as the calculation variable of the printing parameters to generate a third instruction.

[0049] An updating module 103 receives the first instruction, the second instruction and / or the third instruction of the judging module, and updates the mode for executing color correction and the variables for calculating correction parameters of the color correction mode;

[0050] The execution module 104 is used to execute color correction.

[0051] In one embodiment of the present application, Figure 2 As shown, a color correction method is provided, which is executed in an image forming device, and the method includes:

[0052] S201, obtaining a first parameter value; wherein the first parameter value quantitatively represents the relevant conditions that trigger the image forming device to perform color correction, and the first set threshold represents the rated range of normal operation of the original source of the first parameter value.

[0053] S202, determining whether the first parameter value is within a first set threshold;

[0054] S203: If the first parameter value exceeds a first set threshold, continue to determine a first color correction mode associated with the first parameter value.

[0055] This step determines whether the first parameter value corresponding to the color correction-related condition and the first set threshold value of the corresponding color correction-related condition are valid, and can also determine whether the original source is in normal working condition. If an abnormality is found, the color correction is stopped in time. At the same time, the cause of the color correction error can be accurately obtained, which is convenient for subsequent replacement or repair of the original source. It should be known here that the original source refers to temperature detectors, temperature detectors, paper page detection components, powder box replacement detectors, etc., and the devices or components that can obtain the color correction condition parameters in the first time are not listed here one by one.

[0056] S204, if the first color correction mode includes the automatic mode, disconnect the automatic mode of the first color correction mode. . In this step, when it is determined that the current color correction mode includes the automatic mode, disconnect the automatic mode of the first color correction mode, perform manual correction, timely avoid frequent triggering of automatic correction caused by abnormal color correction condition parameter values, avoid the temperature factor in the current printer directly affecting the execution and correction effect of color correction, reasonably control the execution times of correction triggering, prevent abnormal triggering of automatic color correction, reduce unnecessary color correction times, and save toner.

[0057] In one embodiment of the present application, the first parameter value includes at least one parameter, and the first set threshold is a set of parameter ranges corresponding to the first parameter value. In this example, the first parameter value can be one or more parameter values, and the first set threshold is the rated operating parameter range when the original source of each parameter value in the first parameter value works normally.

[0058] For example, if the first parameter value is the temperature value detected by the temperature detector near the LSU, the first set threshold corresponds to the normal / rated operating temperature range of the temperature detector near the LSU. The first set threshold is the basis for determining whether the original source is in normal working condition.

[0059] In a scenario of an embodiment of the present application, the ambient temperature in the printer can be used to adjust the offset parameter (topmargin) of the color set. In actual printing, the temperature abnormality of the LSU will cause the color toner of the entire image to move lower than the black toner. In addition, factors such as temperature / temperature will directly affect the correction effect. During the color correction process, the correction includes the function correction of the toner concentration. The current temperature value will be involved in the calculation. Because the temperature value input exceeds the allowable temperature of the printer, the calculation result will be abnormal, which may be too dark or too light.

[0060] An embodiment of the present application, such as Figure 3 As shown, a color correction method is provided, which is executed in an image forming device, and the method includes:

[0061] S301, obtaining a first parameter value;

[0062] S302, determining that a first parameter value is within a first set threshold;

[0063] S303, determining whether the first parameter value exceeds a second set threshold; wherein the second set threshold is a parameter setting range indicating that the original source of the first parameter value satisfies the normal working state of the image forming device.

[0064] S304: Use a second set threshold value close to the endpoint value of the first parameter value as a variable for calculating the correction parameter in the current color correction mode. The second set threshold value range is less than or equal to the first set threshold value.

[0065] In one embodiment of the present application, a first parameter value is obtained, and the first parameter value is compared with a second set threshold value. If the first parameter value is within the first set threshold value and the first parameter value exceeds the second set threshold value, a second instruction is generated to use the second set threshold value close to the endpoint value of the first parameter value as a variable for calculating the correction parameter of the current color correction mode; the first parameter value is the temperature value detected by the IDC temperature sensor. Figure 4As shown, the second set threshold value in this embodiment is the effective operating temperature range of the printer (-10℃~40℃), then the temperature value detected by the IDC temperature sensor is between -40℃~-10℃, and -10℃ is used as a trigger condition and participates in the calculation of printing parameters. Similarly, if the temperature value detected by the IDC temperature sensor is between 40℃~125℃, 40℃ is used as a trigger condition and participates in the calculation of printing parameters. The method of this embodiment obtains relatively accurate color calculation correction parameter variables by comparing the first parameter value with the second set threshold value to ensure the quality of color correction. The quality of color correction is reflected in the overall printing effect of the printer, such as the color matching effect and the toner concentration effect.

[0066] In one embodiment of the present application, when the first parameter value is within the second set threshold, the first parameter value is used as a variable for calculating the correction parameter in the current color correction mode. In this embodiment, when the temperature parameter value is normal and meets the printer operating temperature range, the first parameter value is used as the calculation parameter for color correction.

[0067] In one embodiment of the present application, if the first parameter value exceeds the first set threshold value, a conventional value is introduced as a variable for calculating the correction parameter in the current color correction mode; the conventional value is a parameter value that satisfies the normal working state. In this embodiment, when the temperature parameter value exceeds the rated detection temperature range of the temperature detector, that is, when the temperature detector works abnormally, in order to keep the printer working stably and ensure that the temperature value required for the color correction calculation meets the printer working temperature range, the normal temperature value is used as the calculation parameter for color correction to ensure that the color correction quality is in a normal state.

[0068] like Figure 5 As shown in the figure, the process of color calibration of the printer is as follows:

[0069] The printer receives the instruction, starts the job printing / starts preheating, and simultaneously starts the color correction temperature detection. The IDC sensor temperature value is obtained through the temperature sensor near the IDC end. The color correction method of this application is used to determine the current state of the temperature sensor. If the temperature sensor state is abnormal, the associated conditions for temperature triggering automatic color correction are turned off and the manual color correction mode is executed. If the temperature sensor state is normal, it is determined whether the obtained IDC sensor temperature value meets the color correction trigger condition. If the color correction trigger condition is met, automatic color correction is performed.

[0070] In one embodiment of the present application, during the automatic / manual color correction process, when the concentration adjustment function is executed, it is necessary to compare the detected temperature value with the rated temperature of the temperature sensor to determine whether the temperature sensor is within the normal working temperature range. If so, the temperature value detected by the temperature sensor is used to participate in the concentration adjustment parameter calculation in the color correction concentration adjustment, and then the color correction is executed. If not, the temperature value detected by the temperature sensor is used. Figure 3 The steps shown, for example: compare the temperature value detected by the temperature sensor with the temperature value of the printer under normal working conditions. When the detected temperature value is greater than the temperature value of the printer under normal working conditions, select the power-off value of the temperature value of the printer under normal working conditions that is closer to the detected temperature value as the variable for calculating the correction parameters in the current color correction mode, perform color correction, and the printer is ready.
