Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In the related art, an image forming apparatus generally performs color correction when a consumable item used is a new one, the number of pages of a job reaches a set value, or the environmental temperature and humidity change is large. However, in this way, there is a possibility that the image quality of the image output by the image forming apparatus is already poor, but the trigger condition for color correction is not yet reached. The image forming apparatus cannot trigger color correction when the output image quality is poor, and the operation effect of the image forming apparatus is affected.

In order to solve the above problems, an embodiment of the present invention provides a color correction method. When the method of the embodiment of the invention obtains the to-be-processed operation, the first image can be inserted into the paper interval of the to-be-processed operation. The first image may enter a workflow of image formation with the job to be processed. Wherein, in the process of the first image formation, the image forming apparatus may acquire a detection result of the transfer image formed by the first image. According to the detection result, the image forming apparatus can judge the image quality of the currently output image, and further can judge whether the condition for triggering color correction is currently reached. And color correction can be performed in time when the condition for triggering color correction is reached, thereby ensuring the image quality effect of the image output by the image forming apparatus.

Referring to fig. 1, a schematic structural diagram of an image forming apparatus according to an embodiment of the present invention is provided. As shown in fig. 1, the image forming apparatus includes a processing section, an imaging device, an acquisition device, and a storage unit. The imaging device, the acquisition device and the storage unit are all electrically connected with the processing component. The process unit is a main control unit of the image forming apparatus for controlling the image forming apparatus, the collecting device, and the storage unit. The storage unit is used for storing program instructions for being executed by the processing component, and storing intermediate data required by the program instructions in the running process, data acquired by the sensor component and the like so as to be called by the processing component for running. The imaging device is used for imaging the job to be processed under the control of the processing component. As shown in fig. 2, the image forming apparatus mainly includes a developing assembly, an LSU assembly, an image carrier, and the like. The acquisition device is used for acquiring related data of the environment where the imaging equipment is located. As shown in fig. 3, the acquisition device may include a CTD sensor, a temperature and humidity sensor, and the like. The CTD sensor is used to detect a transferred image formed on an image carrier, which may be an intermediate transfer belt or a photosensitive drum. The temperature and humidity sensor is used for collecting the temperature and humidity of the current environment. The specific distribution structures of the developing assembly, the LSU assembly, the image carrier, the CTD sensor, and the temperature and humidity sensor are shown in fig. 4.

Referring to fig. 1 to 4, the operation procedure of the image forming apparatus includes: the processing section acquires a job to be processed. In order to be able to determine the timing of triggering the color correction during execution of the job to be processed, the processing section inserts a first image in a paper interval of the job to be processed, the first image entering an image forming flow with the job to be processed. Specifically, the processing section converts the job to be processed and the inserted first image into an image to be formed. The processing section controls the LSU to expose the photosensitive drum to which the uniform charge has been applied, in accordance with the image to be formed, to form an electrostatic latent image corresponding to the image to be formed on the photosensitive drum surface. Further, the process section controls the developing device to supply the developer to the electrostatic latent image to form a visible image on the photosensitive drum surface. As shown in fig. 4, Y, M, C and K are used to supply yellow, magenta, cyan, and black developers, respectively. The visible image formed on the surface of the photosensitive drum can be transferred onto the transfer belt. The image on the transfer belt is used to transfer to an imaging medium, thereby forming an image on the imaging medium. Alternatively, the embodiment of the present invention also refers to an image formed on a photosensitive drum or a transfer belt as a transfer image. Alternatively, the embodiment of the invention can transfer the transfer image corresponding to the job to be processed onto the imaging medium, and the transfer image of the first image can not be transferred onto the imaging medium, so that the normal execution of the job to be processed can be ensured.

In some examples, the image forming device includes a CTD sensor. As shown in fig. 4, the CTD sensor includes a left CTD sensor and a right CTD sensor. The left CTD sensor and the right CTD sensor are disposed on both sides of the transfer belt in the width direction of the transfer belt. The left CTD sensor and the right CTD sensor can detect the transferred image on the transfer belt, particularly the transferred image of the first image, when the job to be processed and the first image form the transferred image on the transfer belt. The left CTD sensor and the right CTD sensor transmit the detection result to the processing section. The processing unit judges whether the timing of triggering the color correction is currently reached or not according to the detection result of the CTD. The embodiment of the invention detects the transfer image through the CTD sensor arranged on the transfer belt, thereby facilitating the implementation of the color correction method of the embodiment of the invention. Further, the image forming apparatus further includes a temperature and humidity sensor therein. As shown in fig. 4, a temperature and humidity sensor may be provided on the transfer belt or the LSU assembly for detecting the temperature and humidity of the environment. The temperature and humidity sensor transmits the acquired environmental temperature and humidity data to the processing component. The processing unit may determine whether the timing of triggering color correction is currently reached by combining the ambient temperature and humidity based on the CTD detection result, or the processing unit may determine what color correction mode is adopted or what image is used as the first image according to the ambient temperature and humidity.

Referring to fig. 1 to 4, the embodiment of the invention further provides a color correction method. Referring to fig. 5, a flowchart of a color correction method according to an embodiment of the present invention is provided. The execution subject of the method shown in fig. 5 is an image forming apparatus, more specifically, a process section in the image forming apparatus. As shown in fig. 5, the processing steps of the method include:

101, acquiring a job to be processed. Alternatively, the image forming apparatus may acquire the job to be processed from the electronic apparatus or directly acquire the job to be processed stored in advance by the image forming apparatus. The electronic device may be, for example, a computer, a notebook computer, a mobile phone, a wearable device, a vehicle-mounted device, an intelligent home device, an augmented reality (augmented reality, AR)/Virtual Reality (VR) device, etc., and the embodiment of the present invention does not limit the specific type of the electronic device.

102, inserting a first image in a paper interval of a job to be processed, the first image being used to trigger color correction. Optionally, the job to be processed typically comprises a plurality of job pages. During the imaging of the plurality of job pages, it is often desirable to maintain a spacing between adjacent job pages, which may be referred to as a paper pitch. In some examples, the image forming apparatus may insert the first image in the paper space between the adjacent job pages, the first image having a smaller size than the paper space between the adjacent job pages, whereby the first image may be inserted without affecting the normal execution of the job to be processed, ensuring the normal execution of the job to be processed. In some other examples, the first image may be inserted as a job page between adjacent job pages of the job to be processed in a manner equivalent to inserting additional job pages in the job to be processed. In this way, the first image is inserted, and transfer image formation of the subsequent job page can be continued after the first image transfer is completed.

103, a detection result of a transferred image of the first image formed on the image carrier is acquired. After the image forming apparatus inserts the first image in the paper interval of the job to be processed, the first image enters the image forming process along with the job to be processed. When the first image forms a transferred image on the image carrier, a CTD sensor provided to the image carrier may detect the transferred image of the first image and generate a detection result. The CTD sensor transmits the detection result to the processing section. Alternatively, the first image may be imaged only on the image carrier, but not transferred to the imaging medium.

104, judging whether the detection result reaches the condition triggering color correction. Alternatively, the detection result may include a color shift value or a patch density value of a transferred image of the first image formed on the image carrier. The image forming apparatus may determine whether a condition for triggering color correction is reached based on the color shift value or the patch density value in the detection result. If so, step 105 is performed.

105, if so, the image forming apparatus performs color correction. Alternatively, when the detection result transmitted by the CTD sensor reaches the condition for triggering color correction, the image forming apparatus may suspend printing of the remaining jobs of the job to be processed to perform color correction first, or the image forming apparatus may perform color correction after the execution of the current job to be processed is ended. The method of the embodiment of the invention can trigger color correction in time according to the detection result of the image inserted in the paper interval, thereby ensuring the timeliness of the image forming equipment for executing the color correction method and ensuring the image quality effect of the image output by the image forming equipment.

Referring to fig. 6, a flowchart of another color correction method according to an embodiment of the present invention is provided. As shown in fig. 6, the processing steps of the method include:

201, the image forming apparatus acquires a job to be processed.

202, the image forming apparatus determines a target correction mode from among a plurality of correction modes. Alternatively, the image forming apparatus may set a plurality of correction modes in advance, and each correction mode may be associated with at least one correction trigger image. For example, a patch density correction mode and a chromatic shift value correction mode may be set. The patch density correction mode and the chromatic shift value correction mode may be associated with at least one correction trigger image, respectively. The patch density correction mode judges whether or not a condition for triggering color correction is reached by detecting a patch density of a transfer image formed by the first image. The color shift value correction mode judges whether a condition for triggering color correction is reached by detecting a color shift value of a transfer image formed by a first image.

In the embodiment of the present invention, after the image forming apparatus acquires the job to be processed, the image forming apparatus may determine the target correction mode from among the plurality of correction modes. Alternatively, the image forming apparatus may determine the target correction pattern according to the current environmental temperature and humidity, the number of pages of the job to be processed, and/or the current imaging medium.

203, the image forming apparatus determines a first image for insertion in a paper interval of a job to be processed from at least one correction trigger image associated with a target correction pattern.

204, the image forming apparatus inserts a first image into a paper interval of the job to be processed, the first image being used to trigger color correction.

205, the image forming apparatus acquires a detection result of a transferred image of the first image formed on the image carrier, the detection result including a color shift value or a patch density value of the transferred image.

206, the image forming apparatus determines whether the color shift value or patch density value of the transferred image reaches a condition that triggers color correction.

207, if so, performing color correction.

According to the embodiment of the invention, the target correction mode can be determined from a plurality of correction modes through the current environment temperature and humidity, the number of pages of the to-be-processed operation and/or the current imaging medium, so that the selected correction mode and the first image added with the paper interval can be more matched with the to-be-processed operation, and the determined trigger color correction time is more reasonable.

Further, in the embodiment of the present invention, the first image inserted into the job to be processed has a preset color patch density or color patch position. If the image quality of the image output by the image forming device is good, the color register offset value or the color lump concentration value acquired by the CTD sensor is within a preset range value. If the color shift value or the patch density value acquired by the CTD sensor exceeds a preset range value, it may be determined that a condition triggering color correction is currently reached, and the image forming apparatus may perform color correction. In the embodiment of the invention, the color register offset value or the color patch density value of the current transfer image can represent the imaging quality of the current output image of the image forming device. Therefore, the time for triggering the color correction determined according to the color register offset value or the color patch density value of the current transfer image is also more timely and accurate, and the situation that the image quality of the image output by the image forming equipment is poor but the color correction is not triggered yet is avoided. Further, the image forming apparatus may perform color correction on the remaining jobs of the current job to be processed after determining to perform color correction or may perform color correction after the execution of the current job to be processed is ended.

Referring to fig. 7, a schematic diagram of dividing a complete corrected trigger image into a plurality of sub-images is provided according to an embodiment of the present invention. As shown in fig. 7, the entire correction trigger image may be stored in advance in the storage unit of the image forming apparatus. Alternatively, the complete corrected trigger image may include a left corrected trigger image and a right corrected trigger image. The left correction trigger image and the right correction trigger image are distributed on two sides of the operation page along the length direction of the operation page. When the complete correction trigger image is image-formed as a job page, transfer images of the left correction trigger image and the right correction trigger image can be detected by the left CTD sensor and the right CTD sensor, respectively. In the example given in fig. 7, the complete correction trigger image may be divided into several sub-images, each sub-image comprising left and right color patches, the sub-images having a height less than the paper spacing between adjacent job pages. In the related art, the paper pitch of the job to be processed is blank. In the example given in fig. 8, after the job to be processed is acquired, one sub-image may be inserted in each paper pitch of the job to be processed, the inserted sub-image being the first image described above.

In some embodiments, after dividing the complete correction trigger image into several sub-images, each sub-image may be numbered. Accordingly, the sub-images can be inserted one by one in the paper pitch of the job to be processed according to the numbering order of the sub-images. For example, a sub-image with the number 1 is inserted in the paper interval between the job page (1) and the job page (2), a sub-image with the number 2 is inserted in the paper interval between the job page (2) and the job page (3), and so on until the sub-images are inserted in the respective sub-intervals of the job to be processed. In some embodiments, after the image forming apparatus acquires the detection results of all the sub-images inserted into the job to be processed or the detection results of all the sub-images required for the completion of the color correction, it is determined whether the condition for triggering the color correction is reached according to the acquired detection results. According to the embodiment of the invention, the sub-image for triggering color correction is inserted into the paper interval of the job to be processed, so that the time for triggering color correction can be determined under the condition that normal execution of the job to be processed is not influenced.

Referring to fig. 9, another schematic diagram of inserting a first image in a paper interval of a job to be processed according to an embodiment of the present invention is provided. In the example given in fig. 9, a complete correction trigger image, which is the first image, may be inserted as a job page between adjacent job pages of the job to be processed. As shown in fig. 9, a complete correction trigger image may be inserted between the job page (1) and the job page (2), and the complete correction trigger image is a job page, where a certain paper distance is set between the job page and the job page (1) and the job page (2). Of course, in the embodiment of the invention, a plurality of complete correction trigger images can be inserted into the to-be-processed operation. When a plurality of complete corrected trigger images are inserted, the plurality of complete corrected trigger images are not adjacent. In the embodiment of the invention, the correction trigger image is used as the job page to be inserted into the image to be processed, and the transfer of the job to be processed can be continued after the transfer of the correction trigger image is completed, so that the job to be processed is not required to be interrupted, and the execution of the job to be processed is not influenced.
