Abstract
In a case where the density correction condition of an image output section is satisfied while a job is being executed, density correction means performs density correction while the job is being executed or after the execution of the job. On this occasion, if there is a job on standby for printing in an image memory, this job is executed in the image formation condition (i.e. a correction amount stored in a current correction amount storing section) determined before the density correction. In the meanwhile, a job which is stored after the density correction is executed in a latest image formation condition (i.e. a correction amount stored in a latest correction amount storing section) which is figured out by the aforesaid density correction.
Description
Technical field
The present invention relates to the image processing system of electronics description modes such as a kind of suitable duplicating machine, printer, particularly, relate to (in the lettering) detectable concentration correction implementation condition in image forms, satisfying the image processing system of implementing concentration correction under the situation of this condition.
Background technology
In the image processing system that is suitable for electronics description mode, because the deterioration of photoreceptor etc., device are over time, the image quality of printed matter (concentration) changes.Therefore, in above-mentioned image processing system,, need suitably carry out concentration correction and handle in order to proceed lettering with certain image quality.This concentration correction processing is undertaken by the image forming conditions variation that makes development bias voltage and charged bias voltage etc. usually.
In order to carry out such concentration correction, above-mentioned image processing system monitors the concentration correction implementation condition that whether has satisfied regulation, carries out concentration correction when having satisfied this concentration correction implementation condition and handles being judged as.As being judged as one of the situation that satisfied concentration correction implementation condition example, for example when the power connection of image processing system, when changing painting box, perhaps when reaching regulation output number etc.
On the other hand, in present image processing system, have the video memory that to store a plurality of operations, when in the lettering of certain operation, requiring the lettering of other operations is arranged, will require relevant job storage in above-mentioned video memory with this new lettering.And the operation that is stored in the above-mentioned video memory is carried out lettering according to the order that is accommodated in the video memory.
In addition, by the operation of above-mentioned image processing system lettering is to read original copy and the data that obtain by image read-out, or the data that send to this image processing system from the computing machine that is connected with network, the relative data of importing carry out that γ handles and the basis of image processings such as screening (screen) processing on carry out lettering.
In addition, in above-mentioned image processing system, be stored in the video memory and wait for the operation of lettering, in order when taking turns to its lettering, to carry out lettering rapidly, and under the state of having implemented these Flame Image Process (γ handles and Screening Treatments), store in the video memory.This technology is disclosed Japanese publication communique spy and opens in the flat 11-289436 communique (on October 19th, 1999 is open: hereinafter referred to as patent documentation 1).
But, in above-mentioned existing structure, in the lettering action, satisfy under the situation of concentration correction implementation condition, produce following problem.
That is, have in the action of the lettering of certain operation, the lettering number that begins to accumulate during from previous concentration correction arrives the regulation number and satisfies the situation of concentration correction implementation condition.At this moment, implement concentration correction if interrupt the operation in the lettering and handle, then since same operation midway image forming conditions change, so this operation midway the image quality of printed matter change.
On the other hand, also have under the situation of the operation in the lettering, but also carry out the concentration correction processing behind the printing ending of this operation in the moment of having satisfied the concentration correction implementation condition.But, at this moment, in the moment video memory that has satisfied the concentration correction implementation condition, store under other the situation of operation, have the problem that the operation that is stored in relatively in this video memory can not be carried out lettering with suitable image forming conditions.
This is the inconsistent problem that causes of image forming conditions during with relative this operation lettering owing to the Flame Image Process that operation is implemented (γ handles and Screening Treatment).Promptly, be stored in operation in the video memory before lettering, to have implemented γ and handle and the state of the Flame Image Process of Screening Treatment is accommodated in the video memory, but because the image forming conditions of these Flame Image Process during with lettering has relevant relation, so the image forming conditions must make above-mentioned Flame Image Process that operation implements with lettering the time is consistent.
Therefore, handle as if carrying out concentration correction under the state that in video memory, stores the operation of having implemented Flame Image Process, image forming conditions changes, image forming conditions when then producing Flame Image Process that operation implements and lettering is inconsistent, can not carry out the problem of lettering with suitable image forming conditions.This problem is particularly remarkable when the lettering of coloured image.
For fear of the problems referred to above, consideration has the moment of the printing ending of the All Jobs in being stored in video memory to carry out the scheme that concentration correction is handled.But, in this case,, have concentration correction and handle and to delay though be the state that has satisfied the concentration correction implementation condition, do not carry out that concentration correction is handled and the possibility that continues a large amount of operation letterings.Particularly, if image processing system is required a large amount of lettering operations, be stored in situation that the operation in the video memory do not disappear and prolong and continue, a large amount of relatively operations are continued for a long time with the situation that the state of not implementing concentration correction and handling carries out unsuitable lettering.
Perhaps, have under the situation that is stored in the operation in the video memory in the moment of satisfying correction concentration implementation condition, also might before the lettering processing is carried out in its operation relatively, implement on the basis of concentration correction processing, this operation is suitable for again the Flame Image Process (γ handles and Screening Treatment) of the image forming conditions after concentration correction is handled.But at this moment, by Flame Image Process is carried out in the operation that is stored in video memory again, the burden of the image processing part of image processing system increases.In addition, this moment is owing to the lettering processing of the operation that above-mentioned lettering is waited for is delayed, so the lettering performance of image processing system reduces.

In addition, the structure of image processing system shown in Figure 2 only is an example, and the present invention is not limited to this.Image processing system of the present invention can be a duplicating machine, can be printer also, or has the compounding machine of the two function.In addition, image processing system science and technology of the present invention is carried out colored lettering, also can only have the function of black and white lettering.
Image processing system of the present invention carries out image by electronics description mode and forms, and, have the video memory that can store many operations.As an embodiment that is suitable for image processing system of the present invention, Fig. 1 has represented the structure of digital color copier.This digital color copier is made of image-input device 60, image output device 70 as shown in Figure 1.
Image-input device 60 is made of the scanner section that for example has CCD (Charge Coupled Device), will (R: red, G: green, B: simulating signal indigo plant) is read by CCD, to image output device 70 inputs as RGB from the reflected light picture of original copy.The Flame Image Process that image output device 70 is stipulated from the view data of image-input device 60 inputs relatively go up output with the view data of having implemented Flame Image Process to recording medium (for example paper etc.), carry out image by electronics description mode and form.In addition, image input part 60 is not contained in the image processing system of the present invention, can be connected with the outside yet.In addition, image input part 60 is not limited to scanner, also can be that PC etc. is by the signal conditioning package of network to image output device 70 input image datas.
Promptly, image processing part 71 is by toning (shadding) correction portion 711, handle carrying out smoothing processing, vividization processing by the view data of image-input device 60 inputs and becoming doubly, the γ that is implemented the brightness identical with the gamma characteristic of image efferent 74/concentration conversion and duplicating concentration correction etc. by γ adjustment handling part 712 handles, implement from the color conversion processing of RGB by color conversion processing unit 713, and carry out deep or light (dither) processing, error diffusion processing etc. by intermediate treatment portion 714 to CMYK.And, to implement compression by the 715 pairs of view data of compression/extension section and handle, the control by control part is stored in this view data in the video memory 72.
The temporary transient storage of video memory 72 from the view data of image-input device 60 inputs, be that lettering requires operation.Because above-mentioned image processing system has video memory 72, so when requiring other operation letterings are arranged in the lettering of certain operation, the job storage by will this new lettering requirement can be stored a plurality of operations in video memory 72.
Next key diagram is handled as the concentration correction of efferent 74.The concentration correction of this image processing system is handled by being undertaken by the image forming conditions of concentration correction portion 75 modified-image efferents 74.
That is, above-mentioned concentration correction was handled before common image forms, and made the toner picture practically to photoreceptor and transfer materials conveying belt etc., detected the optical characteristics of the reflection light quantity etc. of its toner picture, obtained the image forming conditions that obtains desired concentration.
Such concentration correction handles when power connection, when changing painting box, carry out during perhaps every output regulation number, forms a plurality of assemblies corresponding with normal concentration benefit (patch) images on photosensitive drum body.Then, via exposure, development, transfer printing and should piece together complement and look like to be transferred on the transfer materials conveying belt.Measure the concentration that is transferred to the assembly complement picture on the transfer materials conveying belt by concentration detection sensor.
There is the concentration of the assembly complement picture of above-mentioned concentration detection sensor mensuration to be sent to concentration correction portion 75, compares with the concentration reference value.Concentration correction portion 75 carries out concentration correction under the situation of the concentration relative concentration reference value generation deviation of piecing together the complement picture.That is, the image forming conditions of image efferent 74 is changed, so that the concentration of assembly complement picture is consistent with the concentration reference value.As the method for carrying out concentration correction, consider to have (1) to make the method for development bias variations, (2) make the method for charged potential change, the method that (3) change all speed ratios of development sleeve by the irradiation of maximum exposure amount; Or the like.That is, when concentration correction was handled, the image forming conditions of being obtained by concentration correction portion 75 was as the correction of developing bias supply and charged current potential etc. and be stored in the correction storage part 73.
In addition, above-mentioned concentration correction is handled under the situation of image processing system formation coloured image and is implemented one by one with respect to image forming part of all kinds.
The purpose of the image processing system of present embodiment is, in the lettering of certain operation, satisfy the concentration correction implementation condition, and in video memory 72, have this moment under the situation of the view data of waiting for lettering, can carry out concentration correction rapidly and handle, and can both carry out suitable lettering the All Jobs that is stored in the video memory 72.
Therefore, in above-mentioned image processing system, when satisfying the concentration correction implementation condition, inject in the operation in lettering and carry out under the situation that concentration correction handles, carry out lettering about having finished γ processing and Screening Treatment and be stored in the operation of the wait lettering in the video memory 72, used the concentration correction amount of implementing before the concentration correction (present situation correction).On the other hand, implement γ processing and the Screening Treatment that the operation of background storage in video memory 72 is adapted to the concentration correction amount (up-to-date correction) after concentration correction is implemented, therefore use up-to-date correction to carry out lettering handling in concentration correction.
For example, as shown in Figure 4, in video memory 72, store operation A～D, when operation A satisfies the concentration correction implementation condition in lettering, concentration correction handle operation A midway or operation A carry out when stopping.Therefore, the concentration correction amount (present situation correction HT1) before the operation A of lettering obviously implements its image forming conditions as concentration correction before implementing the concentration correction processing is carried out lettering.In addition, if implemented the concentration correction processing, then try to achieve new image forming conditions thus, be up-to-date concentration correction amount (up-to-date correction HT2).
Then, the operation B～D for wait for lettering in the moment of satisfying the concentration correction implementation condition tries to achieve above-mentioned up-to-date correction in the stage of carrying out its lettering.But these operations B～D is not owing to obtaining up-to-date correction HT2 to the moment of video memory 72 storages, so implement the Flame Image Process corresponding with present situation correction HT (γ handles and Screening Treatment).Therefore, these operations B～D carries out lettering with its image forming conditions as present situation correction HT1.
After above-mentioned concentration correction is handled enforcement, have in generation under the situation of new operation E, the Flame Image Process (γ handles and Screening Treatment) of this operation E is implemented the Flame Image Process corresponding with up-to-date correction HT2.Therefore, for operation E, its lettering is also implemented up-to-date correction HT2 as image forming conditions.
In order to carry out above-mentioned processing, above-mentioned image processing system has present situation correction storage part 731 and up-to-date correction storage part 732 in correction storage part 73, can store above-mentioned two corrections simultaneously.In addition, in above-mentioned example, when the printing ending of operation D, do not need present situation correction HT1, up-to-date correction HT2 is suggested as new present situation correction.
In above-mentioned image processing system, by using two corrections in this wise, even in waiting for the lettering operation, inject under the situation of implementing concentration correction,, also can access stable image quality even the operation of this wait lettering is not implemented again Flame Image Process such as γ processing and Screening Treatment.In addition, what the operation of implementing the new input in back in concentration correction can prevent by using new correction that the concentration correction of essence from implementing delays, and can guarantee long-term image quality stability.
As mentioned above, the image processing system of present embodiment has the image forming part of suitable electronics description mode, and comprises: the video memory that can store the view data corresponding with a plurality of operations; The view data that will export is carried out the image processing part of Flame Image Process relatively; When above-mentioned image forming part satisfies the concentration correction implementation condition,, the concentration correction that carries out above-mentioned image forming part makes the concentration correction portion of the image forming conditions variation of above-mentioned image forming part for handling, the view data that is stored in the wait lettering in the above-mentioned video memory is to implement the stored data of state of a part of Flame Image Process in the Flame Image Process of being implemented at least in above-mentioned image processing part, and, in the lettering of certain operation, when having satisfied the concentration correction implementation condition of above-mentioned image forming part, carry out the concentration correction processing in the operation output in lettering or after exporting, satisfy the moment of the concentration correction implementation condition of above-mentioned image forming part, handle preceding image forming conditions by above-mentioned concentration correction, lettering is carried out in the operation that is stored in the above-mentioned video memory.
According to said structure, in certain operation lettering, satisfy under the situation of concentration correction implementation condition of image forming part, in the lettering operation output at this moment or carry out concentration correction after the output and handle.Therefore, after arriving the enforcement time that concentration correction handles, what can prevent that the concentration correction of essence from implementing delays, and can promptly carry out concentration correction and handle.
In addition, have under the situation of the wait lettering operation that is stored in the above-mentioned video memory in the moment of the concentration correction implementation condition that satisfies above-mentioned image forming part, the lettering of these operations carries out after concentration correction is handled enforcement.But the image forming conditions before the operation of such wait lettering is handled by above-mentioned concentration correction is carried out lettering.Thus, the image forming conditions of the Flame Image Process that these operations are implemented in advance (γ handles and Screening Treatment) during with this operation lettering do not produce inconsistent, can carry out suitable lettering.
In addition, above-mentioned image processing system, implement and the corresponding Flame Image Process of image forming conditions after above-mentioned concentration correction is handled for handle the operation that is stored in after implementing in the above-mentioned video memory in above-mentioned concentration correction, and carry out lettering by the image forming conditions after the above-mentioned concentration correction processing.
According to said structure, for the operation that is stored in after above-mentioned concentration correction is handled in the above-mentioned video memory, the optimized image that can be suitable for the up-to-date image forming conditions after concentration correction is handled is handled and lettering.
In addition, in above-mentioned image processing system, above-mentioned image forming conditions can be development bias voltage or charged bias voltage.According to said structure, the enforcement that concentration correction is handled is carried out easily.
