DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises an exposure processing section for exposing an image to a photographic photosensitive material and a development processing section for developing the photographic photosensitive material exposed in the exposure processing section. The present invention relates to a development processing state evaluation device for evaluating an operation state of the development processing unit in an image printing apparatus, and an image printing apparatus including the same.

[0002]

2. Description of the Related Art Such a developing state evaluation apparatus evaluates whether or not a photographic photosensitive material exposed in an exposure processing section of an image printing apparatus is properly developed in a developing processing section of the image printing apparatus. It is a device to do. That is, in the development processing section, processing is generally performed using a chemical, and the color development of the photographic light-sensitive material changes depending on the state of the chemical. Therefore, appropriate management and evaluation are required. Conventionally, for such evaluation, an undeveloped calibration photographic light-sensitive material (for example, referred to as a "control strip") in which image information for development processing unit calibration has been exposed in advance from a photographic photosensitive material supplier. And a reference photographic light-sensitive material obtained by subjecting the calibration photographic light-sensitive material to standard processing by a manufacturer. The administrator of the image printing apparatus purchases the undeveloped calibration photographic light-sensitive material and the reference photographic light-sensitive material in order to evaluate the operation state of the development processing unit. After the photographic photosensitive material for use is loaded in a jig for preventing exposure, it is set in an image printing apparatus and developed by a developing section. Next, the color development density of the calibration photographic light-sensitive material and the reference photographic light-sensitive material which have been subjected to the development processing are measured with a densitometer, and the density measurement data of both are compared to adjust the operation of the development processing unit. Get information.

[0003]

Therefore, in the above-mentioned conventional construction, it is necessary to purchase and manage the unexposed calibration photographic light-sensitive material and the like, and there is a disadvantage that the management cost of the image printing apparatus is increased. Was. The present invention has been made in view of the above circumstances, and has as its object to appropriately operate an image printing apparatus while reducing the management cost of the image printing apparatus.

[0004]

According to the present invention, there is provided a calibration photograph in which image information for developing processing section calibration is exposed in an exposure processing section and developed in a developing processing section. Based on the density measurement information of the photosensitive material, it is evaluated whether the processing operation of the development processing unit is appropriate. In other words, the photographic photosensitive material for calibration is manufactured by the image printing apparatus itself, and the exposed photographic photosensitive material is directly used by using the apparatus configuration originally provided in the image printing apparatus, such as a transport apparatus for the photographic photosensitive material. The photographic light-sensitive material for use is sent to a development processing section for development processing.

Accordingly, the cost for purchasing the unexposed calibration photographic light-sensitive material and the management cost of the purchased calibration photographic light-sensitive material can be reduced. The density information of the image of the photographic light-sensitive material includes not only information on the processing by the development processing unit but also information on the fluctuation of the exposure amount when the light amount in the exposure processing unit changes with time. By strictly managing the exposure processing unit, it is theoretically possible to exclude information on the exposure processing unit, but such strict management is not easy in practice.

Therefore, the density measurement information of the calibration photographic light-sensitive material developed in the development processing section by the data processing means and the standard density information to be held when the calibration photographic light-sensitive material is properly developed. Influence components of the exposure processing in the difference information can be suppressed, and necessary measures can be taken for the development processing unit based on the result information. Thus, the image printing apparatus can be properly operated while reducing the management cost of the image printing apparatus. The standard density information for reference may be stored as data by providing a storage means such as a memory, or a photographic light-sensitive material for calibration may be prepared in advance as a reference, and developed. The density may be obtained by measuring the density each time the evaluation processing of the development processing unit is performed by the state evaluation device.

[0007] With the above configuration, the data processing means performs development processing in the development processing section based on measurement information of the exposure light quantity measurement means provided in the exposure processing section. The influence component of the exposure processing in the difference information between the density measurement information of the calibration photographic light-sensitive material and the standard density information is suppressed. That is, by directly measuring the change in the exposure state in the exposure processing unit by the exposure light amount measurement unit, the influence component of the exposure processing is suppressed, so that the influence of the exposure processing unit can be accurately excluded. The operation state of the development processing unit can be evaluated by effectively utilizing the density measurement information of the photographic photosensitive material for calibration.

Further, with the configuration according to the third aspect of the present invention, the data processing means obtains the image information for calibration of the development processing section exposed on the calibration photographic photosensitive material.
By extracting calibration information that is not affected by the exposure processing in the exposure processing unit, the influence component of the exposure processing is suppressed. In other words, the image information for the development processing unit calibration includes information that is not affected by the exposure processing in the exposure processing unit. By extracting such information as calibration information, the exposure processing unit is exposed to light. Even when a means for measuring the amount of light for use is not provided, it is possible to suppress the influence component of the exposure processing, and to evaluate the operation state of the development processing unit.

Further, by providing the configuration according to the fourth aspect, the image information for calibrating the development processing section is provided with an unexposed area where the photographic photosensitive material is not irradiated with light. That is, since the unexposed area is essentially unaffected by the fluctuation of the operation state in the exposure processing section, the data processing means
The density information of the unexposed area is extracted as the calibration information, and can be used for evaluating the operation state of the development processing unit.

[0010] In addition, by providing the configuration according to the fifth aspect, the image information for calibrating the development processing section is provided with a saturated exposure area for exposing at an exposure amount equal to or greater than the saturation exposure amount of the photographic photosensitive material. That is, when the exposure amount of the photographic light-sensitive material is generally increased to some extent, even if the exposure amount is increased, the color development of the photographic light-sensitive material is saturated and hardly changes. With the exposure amount in such a state as the saturation exposure amount, the saturation exposure region exposed with the exposure amount equal to or greater than the saturation exposure amount has a relationship with the color development of the photographic material even if the exposure amount slightly changes. It becomes sufficiently dilute. Therefore, the data processing unit can extract the density information of the saturated exposure area as the calibration information and use the extracted information for evaluating the operation state of the development processing unit.

According to the sixth aspect of the present invention, there is provided a first exposure area for exposing a photographic photosensitive material to an image information for developing processing section calibration at a set exposure amount, and a first exposure area for the first exposure area. A second exposure area for exposing at an exposure amount twice as large as the exposure amount, wherein the data processing means includes density information of the first exposure area as calibration information which is not affected by the exposure processing in the exposure processing unit. And contrast information is extracted from the density information of the second exposure area. That is,
If the relationship between the exposure amount of the first exposure region and the exposure amount of the second exposure region is set to be a multiple as described above, even if the exposure amount of the exposure processing unit fluctuates due to a temporal change of the light amount, the measured density value and the exposure Since the slope of the relationship with the logarithm of the quantity, that is, the contrast information itself does not change, the contrast information can be used for evaluating the operation state of the development processing unit.

According to the seventh aspect of the present invention, there is provided a density measuring means for measuring the density of the calibration photographic light-sensitive material developed in the development processing section. Can be accurately obtained by the development processing state evaluation apparatus itself.

[0013] Further, by providing the constitution according to claim 8, an exposure processing section for exposing an image to a photographic photosensitive material, and a developing section for developing the photographic photosensitive material exposed in the exposure processing section. An image printing apparatus provided with a processing unit is also provided with the above-described development processing state evaluation device. As a result, an image printing apparatus capable of appropriately operating the development processing unit while reducing management costs can be provided.

Further, with the configuration according to the ninth aspect, the exposure processing section controls the operation of each light projection element of the exposure head under the control of the exposure control means to set the exposure amount for each pixel. To expose the image. Therefore, when exposing the image information for the development processing section to the photographic photosensitive material, the exposure head is exposed based on the image information for the development processing section calibration stored in the storage means. The material can be manufactured stably.

And the concentration of the object to be measured is determined from the spectrum. The measurement target of the measuring head 30 is mainly the calibration photographic paper 2a as the photographic photosensitive material for calibration shown in FIG.

Is stored in a storage device M as a standard density storage means. The standard density information and the latest density measurement information obtained by the density measurement device CM are stored. Compare. Hereinafter, the processing by the main controller 10 will be schematically described based on the flowchart of FIG.

The processing shown in the flow chart of FIG. 5 does not include the exposure light quantity measuring means EM even in the image printing apparatus IP in which the exposure processing section EX is provided with the exposure light quantity measuring means EM. This is a process that can be applied to the image printing apparatus IP of the type, and the process is slightly different depending on whether or not the exposure light amount measuring unit EM is provided. Although the detailed description of the exposure light quantity measuring means EM is omitted, the exposure head 5a of the present embodiment has:
An optical sensor that is driven to move in the direction in which the light projecting elements of the exposure head 5a are arranged, that is, in the main scanning direction, is arranged at a standby position of the exposure head 5a, and emitted from each light projection element of the exposure head 5a located at the standby position. What is necessary is just to comprise so that the quantity of light which flows may be measured.

In the processing shown in FIG. 5, first, it is confirmed whether or not the above-mentioned exposure light quantity measuring means EM is provided in the exposure processing unit EX (step # 1). Since the means EM is provided, a measurement start command is sent to the exposure light quantity measuring means EM, and the measurement result is received (step # 2). Main controller 1
0 is the difference between the measurement result received from the exposure light amount measuring means EM and the reference light amount to be emitted from the exposure head 5a, and further, density correction data is obtained from the difference, and the density correction data is obtained by the density measurement device CM. In the latest density measurement information of the calibration photographic paper 2a, the density correction data is subtracted from the data of each density step except the unexposed area NE and the saturated exposure area FE (step # 3), and the exposure processing is performed. Suppress influential components.

For this processing, the main controller 1
0, the reference light amount to be emitted from the exposure head 5a is previously stored in the storage device M, and the deviation of the light amount data received from the exposure light amount measuring means EM from the reference light amount is determined by the developed printing. The effect on the density of the paper 2 is measured in advance, and the result is obtained by calculating the difference between the measurement result received from the exposure light amount measurement unit EM and the reference light amount, and the measurement result of the density measurement device CM.

5). This standard density information is also obtained in advance and stored in the storage device M. Standard density information and the latest calibration photographic paper 2
If the deviation from the density measurement information a is within the allowable range, it is determined that the operation state of the apparatus is good (step # 6),
This is displayed on the exposure monitor 10a connected to the main controller 10 (step # 7). If the deviation exceeds the allowable range (step # 6), it is determined that the operation state of the apparatus is not good, and a countermeasure in the development processing unit DE is specified (step # 9).

Among the density measurement information of the calibration photographic paper 2a measured by the density measuring device CM, the information used for the above-mentioned determination is transmitted to the exposure processing unit EX by the exposure processing unit EX as in the present embodiment.

By extracting calibration information that is not affected by the exposure processing in step (4) (step # 4), the components affected by the exposure processing are suppressed. The calibration information includes the density information of the unexposed area NE, the density information of the saturated exposure area FE, and the slope of the relationship between the measured density value and the logarithmic value of the exposure amount in the density measurement information of the calibration photographic paper 2a. There is contrast information.

After that, as in the case where the exposure light quantity measuring means EM is provided, the calibration information is extracted as described above, and thereby the fluctuation printing information of the exposure processing unit EX is sufficiently suppressed. The difference between the density measurement information 2a and the standard density information that should be possessed when the calibration photographic paper 2a is properly developed is determined (step #).
5). This standard density information is also obtained in advance and stored in the storage device M. Standard density information and the latest calibration photographic paper 2
If the deviation from the density measurement information a is within the allowable range, it is determined that the operation state of the apparatus is good (step # 6),
This is displayed on the exposure monitor 10a connected to the main controller 10 (step # 7). If the deviation exceeds the allowable range (step # 6), it is determined that the operation state of the apparatus is not good, and a countermeasure in the development processing unit DE is specified (step # 9).

Of the density measurement information of the calibration photographic paper 2a measured by the density measurement device CM, the information used for the above-mentioned determination is determined when the exposure processing unit EX is not provided with the exposure light quantity measuring means EM. Are the density measurement data of the unexposed area NE and the saturated exposure area FE and the slope of the relationship between the measured density value and the logarithmic value of the exposure amount, that is, contrast information. The allowable range of the deviation is set for each information. From the difference between the density information exceeding the allowable range and the corresponding density information in the standard density information, countermeasures such as setting the replenishment rate of the developing solution to the developing tank of the developing section DE and setting the temperature of the developing solution, etc. Identify the law.

For this specific processing, the storage device M has:
The difference between each of the density information and the contrast information of the unexposed area NE and the saturated exposure area FE and the standard density information, the set value of the replenishment rate of the developing solution, the temperature setting of the developing solution, and the like. Is obtained in advance experimentally and stored as the second development correction data table 42. The countermeasure specified in this way is displayed on the exposure monitor 10a (step # 9), and the operator executes necessary measures while seeing the display.
