Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer control negative film, and more particularly to a printer control negative film for setting print conditions of various photographic printers.

[0002]

2. Description of the Related Art In a photographic printer, the density of a frame to be printed is measured and the printing exposure amount is automatically controlled according to this density. For this reason, the print conditions for determining the printing exposure amount of the photographic printer are set by using a negative film (printer control negative film) having a reference density at the beginning of work.

As shown in FIG. 1 (B), the printer control negative film 2 is commonly called an eyeball negative, and is a reference consisting of one circular pattern portion 3 arranged in the central portion and a background portion 4. The frames 5, 6, 7 and 8 are arranged in this order. The reference frame 5 is a standard exposure frame and is called a normal exposure frame. The reference frame 6 is an underexposure frame and is called an underexposure frame.
Further, the reference frame 7 is an overexposed frame and is called an overexposed frame. Further, the reference frame 8 is an overexposed frame and is called a super-over-exposure frame. The normal exposure frame 5 of the printer control negative film 2 is created as a representative of the customer negative film for which a photographic print is requested. In general, the majority of customer negatives are photographed in daylight daylight or light equivalent thereto from around 10 am to around 2 pm, and have an appropriate exposure negative film density based on film sensitivity. Also, a person occupies about one-third of the frame,
The rest is occupied by green trees, sky, buildings and roads.
The light that is transmitted and mixed through the coma of these properly exposed negative films theoretically has a neutral gray color. Therefore, the printer control negative film 2 in which this neutral gray color is represented by a circular pattern is created. In addition to the reference frames 5, 6, 7 and 8, the printer control negative film 2 has a film base portion 9 which has no film density portion and has a film base density.
Are formed.

Further, instead of the above-mentioned center negative, a picture-containing printer control negative film using an image of a person or the like is also used so that the color tone and density of the sample print can be easily judged visually. There is.

[0005]

However, since the conventional picture-printed printer control negative film merely arranges the image of a person or the like, it is easy to perform visual judgment in comparison with the reference print. There is a problem that it cannot be determined.

SUMMARY OF THE INVENTION The present invention is intended to solve the above problems, and an object of the present invention is to provide a printer control negative film in which the finish condition of sample prints can be visually and easily determined.

[0007]

In order to achieve the above object, a printer control negative film according to a first aspect of the present invention is characterized in that a background portion of a picture of a normal exposure frame has a gray base portion and a base portion made of gray. It is composed of a large number of color patterns scattered and arranged. The color patterns, colors, sizes, and arrangements are set so that each color pattern is assimilated to the base portion by the combination of these color patterns within the reading range of the light receiving element of the photometric means used for setting the printing conditions in the photographic printer. Is preferably defined. Further, in the normal exposure frame, a center portion of the normal exposure frame is arranged, and a face image of a person is arranged on both sides of the center portion, and one of the face images has a darker skin color density than the standard one. However, it is preferable to make the skin color density of the other face image lighter than the standard one. Further, the normal exposure frame is provided with a finish density determination unit at the vertical center position of one lateral end of the normal exposure frame, and a print tint adjustment chart is provided at the vertical center position of the other horizontal end unit. The print density adjustment section is configured such that a white pattern and a gray pattern are adjacent to each other on a print obtained by printing and exposing a normally exposed frame, and the print tint adjustment chart includes a gray pattern and a plurality of gray patterns. It is preferable that each color pattern has a tint that develops when a specific color is biased by a certain amount with respect to the gray pattern. In addition to the picture-printed printer control negative film, a large number of color patterns may be similarly arranged on the background portion of the conventional center negative.

[0008]

FIG. 1A is a plan view showing a printer control negative film embodying the present invention.
The printer control negative film 10 is provided with a source portion 11 consisting of an area having only a film base density, an under-exposure frame 12, a normal-exposure frame 13, an over-exposure frame 14, and a super-over-exposure frame 15. It is made for each film type. Note that reference numeral 1
Reference numeral 6 is a symbol indicating the type of film.

Although each frame 12 to 15 of the printer control negative film 10 is recorded as a negative image, it is not easy to illustrate the negative image, and the display in the negative image is difficult to understand. In A), only the line drawings of the main components and the overall density of each frame are shown. For this reason, each configuration of the normal exposure frame 13 will be described below based on the positive image displayed on the print 18 obtained from the normal exposure frame 13. FIG. 2 is a plan view showing the print 18 obtained from the normal exposure frame 13. A reference print is obtained when the normal exposure frame 13 is printed and exposed under the optimum print condition, and a sample print is obtained when the normal exposure frame 13 is printed and exposed under the reference print condition to set the print condition. Therefore,
In describing each structure of the normal exposure frame 13, the density value refers to the density value on the reference print, and each part of the normal exposure frame 13 is configured to have such a density value. There is. In addition, even if the density is dark or light, the print obtained from the normal exposure frame 13 is used as a reference, and as a matter of course, the reverse relationship is present on the normal exposure frame 13 because it is a negative image.
As is well known, since the base density of the negative film differs depending on the film type, the density in each configuration of the printer control negative film 10 provided for each type also changes according to the film type.

In the central portion of the normal exposure frame 13, FIG.
As shown in the print 18 of FIG. 3, the eyeball portion 20 having a uniform density of neutral gray is arranged on the reference print. The eyeball portion 20 has a circular shape like the eyeball portion of a conventional printer control negative film, and the densities thereof are cyan (C) density = 0.7 and magenta (M) density = 0. 7,
The density on the negative film 10 is determined so that the yellow (Y) density = 0.7. The eyeball portion 20 is used when the density of the sample print or the reference print is measured by using a densitometer in addition to the visual judgment.
The density of the eyeball portion 20 on the reference print may be, for example, 0.6 to 0.6 depending on the model of the photographic printer.
It varies in the range of 0.8.

Face images 2 of a person are provided on both sides of the eyeball portion 20.
1, 22 are arranged. The skin color density of the face image 21 on the left side is set to be dark on the print 18, and is a dark skin face image. The skin color density of the face image 22 on the right side is set to be light on the print 18, which is a light skin face image.
These skin color densities are set to have a density of ± 10% step with respect to the standard skin color density, but this step amount may be appropriately changed. By visually observing the finished densities of these two face images 21 and 22, it is possible to easily determine whether or not the finished densities are appropriate and the color balance is good.

A print tint adjusting chart 25 is arranged at the vertical center of the left end of the normal exposure frame 13. As shown in FIG. 3, this chart 25 includes an outer annular gray area 26 and an inner color scale 2.
7 is comprised. The annular gray area 26 is configured to be neutral gray on the reference print, and its density is cyan density = 0.7, magenta density = 0.7, yellow density = 0.7 on the reference print. The concentration on the negative film is determined so that In addition, this density value is an example,
Depending on the model of photographic printer, it is designed to produce a medium gray density of about 0.6 to 0.9. Further, the color scale 27 is a tint that is produced when the color balance of C, YC, Y, YM, and M with respect to the gray of the annular gray area 26 is biased in the direction of adding 10% to each color. Color patterns 27a, 27 that have a density
b ... 27e. In addition, other MR, R,
For RB, B, BG, G, and CG, color patterns 27f, 27g, ... 27k, 2 are set as tint densities that develop when they are biased in the direction of subtracting 10% to each color.
It is equipped with 7m. Therefore, by visually observing which color pattern 27a to 27m of the color scale 27 of the reference print the tint of the annular gray area 26 of the sample print corresponds to, it is possible to easily determine the tint shift of the printing conditions. . The direction in which the tint shift in each of the color patterns 27a to 27m is generated may be reversed to that described above, or all the color patterns may be unified in either the addition direction or the subtraction direction.

A finished density determination unit 30 is arranged at the center of the right end of the normal exposure frame 13 in the vertical direction. As shown in FIG. 2, the finish density determination unit 30 is composed of a circular white pattern 31 and gray patterns 32 and 33 arranged vertically so as to sandwich the circular white pattern 31. The upper gray pattern 32 has, for example, a density D1 = 0.4 on the reference print, and the lower gray pattern 33
Has a density D2 = 0.3, and the density on the negative film is determined so that each of them has a neutral gray color on the reference print. These gray patterns 32,
Boundaries 34 and 35 between 33 and the white pattern 31 are visually confirmed, and when these boundaries 34 and 35 are clear, it is determined that the finish has an appropriate density. Also, these boundaries 34,
When 35 is unclear, reference print 1
For example, the master balance value or the like is adjusted so that the clarity becomes similar to that of the finished density determination unit of 8.

A finished density determination section 40 for half-size sample printing is arranged below the eyeball section 20. The finish density determination unit 40 is composed of a white pattern 41 and an annular gray scale 42 arranged so as to surround the white pattern 41. The annular gray scale 42 has three gray patterns 42a,
42b and 42c, and the densities on the negative film are determined so that the respective densities have three levels on the reference print. Also,
A triangular positioning mark 43 in the case of a half size is formed on the lower side of the finish density determination unit 40.

Further, the eyeball portion 20, the face image 21 of the person,
22, a print tint adjustment chart 25, and a background portion 47 is formed in the upper margin of the finish density determination portion 30. The background portion 47 is composed of a gray base portion 45 and a color pattern 46 arranged in a dispersed manner on the base portion 45. Each color pattern 46 is formed in a square or a circle, and each color pattern 46 is composed of a specific color having a uniform density. These color patterns 46 have a uniform color balance when they are measured by a scanner,
The color, size, and arrangement are determined so as to be assimilated into 5. That is, in a scanner that measures light on the negative film normally exposed frame 13 such as 10 mm squares as one pixel, the size of each color pattern 46 is 3 on the negative film normally exposed frame 13.
The size of the square is less than or equal to mm, and each color pattern 46 is not affected within the 10 mm square of the photometric pixel.
The color, size, and arrangement of each color pattern 46 are specified so that the result is the same as the result of photometry of only one. Therefore, by visually comparing each color of the color pattern 46 of the sample print with that of the reference print and determining whether or not they are finished the same, it is possible to easily know the deviation of the color balance. If the size of each color pattern 46 is too small, the color pattern 4
Since it is difficult to visually judge the color shift by 6, it is preferable that the size of each color pattern 46 is 1 mm or more on the negative film.
It is preferably 2 mm or more.

FIG. 4 is a schematic diagram showing a printer processor. The printer processor 50 illuminates the frame to be printed of the negative film 52 set on the film carrier 51 by the light source section 53, and connects the transmitted light thereof to the color paper 56 by the printing lens 55 while the shutter 54 is open. Then, the image of the frame to be printed is printed and exposed. The color paper 56 that has been exposed by printing is temporarily stored in a reservoir 57, and then sent to a paper processor 58 for development processing. The developed color paper 56 is cut into individual frames by a cutter, and a print photograph 59 is obtained. And discharged to the tray 60.

As is well known, the light source section 53 is composed of a lamp 61, a light quality adjusting section 62, and a mixing box 63. The light quality adjusting unit 62 inserts cyan, magenta, and yellow color filters 64, 65, and 66 into the printing optical path 68 by the filter driving unit 67, and adjusts the printing light to the light quality and light intensity that match the printing exposure amount. To do.

Further, a scanner 72 including a lens 70 and a color image area sensor 71 is arranged at a position facing the frame to be printed set at the printing position of the film carrier 51. The scanner 72 performs three-color separation photometry on each point of the frame to be printed. This photometric value is sent to the characteristic value calculation unit 73, where characteristic values such as a large screen average transmission density (LATD) and minimum and maximum values are extracted. Further, the characteristic value calculation unit 73 classifies the scenes in a known manner based on the three-color separation density of each point of the frame to be printed, and calculates the exposure correction amount previously determined by a statistical method based on the scene classification result. The LATD, the minimum value, the maximum value, and the exposure correction amount are sent to the printing exposure amount calculation section 74, and the printing exposure amount is calculated using a known exposure amount calculation formula. This printing exposure amount is sent to the controller 75.

The controller 75 is composed of a well-known microcomputer. In addition to performing sequence control of each unit, the controller 75 calculates the set position of each color filter 64-66 based on the exposure amount for printing, and adjusts the light quality of the set position data. It is sent to the filter driving unit 67 of the unit 62. Filter drive unit 6
7 is a filter 64 for each color based on the set position data.
A predetermined amount of 66 is inserted into the printing optical path 68. The controller 75 controls the shutter drive unit 76 to control the shutter 54.
And the transmitted light of the frame to be printed illuminated with the printing light whose light quality is adjusted by the color filters 64-66 is passed through the printing lens 55 to the color paper 56 at the printing position.
The image is formed on the substrate, and the exposure is performed with an appropriate exposure amount. A keyboard 77 and a display 78 are connected to the controller 75 so that various modes can be switched and commands can be input.

Next, setting of print conditions of the photographic printer 50 using the printer control negative film 10 will be described. In this case, the keyboard 7
7 is operated to put the controller 75 in the print condition setting mode. In this print condition setting mode, the controller 75 checks the print condition, for example, the master balance value, according to the processing procedure as shown in FIG.

First, the printer control negative film 10 is set on the film carrier 51, and the normally exposed frame is set at the print position. Next, the screen transmission density is measured by the scanner 72 without operating the exposure correction function based on the scene discrimination by the scanner 72. At this time, a large number of color patterns 46 are assimilated to the base portion 45 by the combination of these color patterns in the reading range of the light receiving element of the photometric means used for setting the printing conditions in the photographic printer so that the same density can be obtained. Since the color, size, and arrangement are defined, the color pattern itself is not detected, and photometry is performed in the same way as the photometry result of only the base portion.

The screen transmission density of the normally exposed frame 13 of the printer control negative film 10 is determined by the characteristic value calculation unit 7
3 is calculated and sent to the printing exposure amount calculation unit 74. The printing exposure amount calculation unit 74 calculates the printing exposure amount based on the obtained screen transmission density and sends it to the controller 75. The controller 75 obtains the set positions of the color filters 64, 65, 66 based on the printing exposure amount, and controls the light quality adjusting unit 62 based on this. In this case, the exposure correction based on the scene discrimination by the scanner 72 is not performed for the calculation of the printing exposure amount. After that, the shutter 54 is opened for a certain period of time, and the normal exposure frame 13 is printed and exposed on the color paper 56. The baking-exposed color paper 56 is sent to a paper processor 58 via a reservoir 57, where it is developed, cut into one frame by a cutter, and a sample print is discharged to a tray 60.

By paying attention to the skin color densities of the obtained dark skin face image 21 and light skin face image 22 of the sample print, it is determined whether or not these are finished in the same manner as the face image of the reference print. When the finished densities are the same, the finished densities determining units 30 and 40 determine whether the finished densities are appropriate from another viewpoint. Further, when the dark skin face image 21 is finished darker than the same reference print, the density correction amount is determined in a direction to correct it and, for example, the master balance value is corrected. If the light skin face image 22 is lighter than the same reference print, the correction is performed to correct it. Since the finish densities of the two face images of the dark skin and the light skin are referred to in this way, the finish densities can be determined easily and accurately. Also, by paying attention to the color balance of the skin color portions of these two face images 21, 22,
The correction direction and correction amount of the color balance can also be known.

The determination by the finish density determination unit 30 is made by the boundary 3 between the white pattern 31 and the gray patterns 32 and 33.
It is performed depending on whether or not 4,35 are clear. For example, when the boundary 34 is clear, it is determined that it is within the upper limit range of the allowable concentration. Further, when the boundary 35 is clear, it is determined to be within the lower limit range of the allowable density. If these boundaries 34 and 35 can be clearly identified, it is determined that the density is appropriate. Also, boundary 3
When 4 is unclear, it is determined that the upper limit of the permissible concentration is exceeded, and the master balance value is corrected. Similarly, when the boundary 35 is unclear, the master balance value is corrected by determining that it is out of the lower limit range of the permissible density.
The correction amount of the master balance value is determined according to the degree of blurring at each boundary.

Further, it is judged using the print tint adjustment chart 25 whether or not the tint needs to be adjusted. That is, the annular gray area 26 on the outside of the print tint adjustment chart 25 of the sample print indicates which color pattern 27a to 2 of the print tint adjustment chart 25 of the reference print.
It is visually judged whether or not it corresponds to 7 m. When the annular gray area 26 does not correspond to any of the color patterns 27a to 27m and has the same tint and density as the annular gray area of the reference print, it is determined that there is no tint shift and the tint adjustment is finished. In addition, any of the color patterns 27a to 27
When the annular gray area 26 of the sample print corresponds to m, the tint is shifted by the amount of color development of the corresponding color pattern. Therefore, the master balance value is adjusted to eliminate this tint shift.

Similarly, the background portion 4 of the sample print
The 7 color pattern 46 is visually compared with the corresponding one of the reference prints to determine whether the color purity corresponds to that of the reference print. As a result, the master print value can be corrected more accurately so as to eliminate the color shift.

The two face images 21 and 22 and the finish density determination unit 30 determine the proper density, and the print tint adjustment chart 25 and the color pattern 46 of the background unit 47 establish an appropriate color balance. If the determination is made, it is possible to omit the next step of measuring the density of each print and automatically correcting the master balance value. If it is difficult to accurately determine the density correction amount and the color balance correction amount by visual inspection, the process proceeds to the density measurement of the next reference print.

In the density measurement, an instruction to measure the density of the center eye portion 20 of the reference print is displayed on the display 78 by the densitometer. According to this display, the reference print is set in the densitometer, and the measurement key is operated to perform the density measurement, and the three-color density of the eyeball portion 20 of the reference print is measured. Densitometer
It is attached to the printer processor, and when the print is set in the slit, the three-color density at the center is automatically measured. This three-color density is 7
8 and the memory 7 of the controller 75
9 is stored. Next, an instruction to measure the density of the central portion of the sample print is displayed on the display 78 by the densitometer, and the three-color density of the sample print is measured. The three-color density is also displayed on the display 78 and stored in the memory 79 of the controller 75.

Next, the density comparison between the reference print and the sample print is automatically performed, and the density comparison value is displayed on the display 78. With reference to this density comparison value, if this is larger than a predetermined value,
The keyboard 77 is operated to instruct the master balance correction. In response to this correction instruction, the controller 75
A master balance correction value is calculated from the density comparison value, and the master balance value of the printing exposure amount calculation unit 74 is corrected by this correction value.

In the above embodiment, the color pattern 46 uses circles and rectangles, but other shapes such as triangles, other polygons, ellipses, hearts, and irregular shapes may be used.

Further, as shown in FIG. 6, a background portion 92 consisting of a base portion 90 and a color pattern 91 may be arranged in place of the conventional center negative, and in this case also, the color balance is visually deviated. You will be able to know.

Further, in the above embodiment, the printer control negative film is used for setting the print condition such as master balance correction, but in addition to this, the printer control negative film is imaged and the monitor CRT is used.
It may be used for brightness adjustment and color balance adjustment of the monitor by displaying on a display such as.

In the above embodiment, the negative type film of 135 type is used, but the negative type film of 110 type or 120 type may be used.
Further, the present invention may be applied to a photographic film having an APS (advanced photo system) format having a function for cueing a film and a function for writing photographing information and the like on a transparent magnetic recording layer.

In the above embodiment, in addition to the visual judgment,
The densitometer is used to determine whether or not the master balance needs to be corrected. However, in addition to this, round exposure may be performed to visually correct the master balance or the like. In this round exposure, as is well known, printing conditions are changed to, for example, 9 steps, and for example, a central portion of a normal exposure frame is continuously printed in a strip shape to perform exposure by exposure, and a sample print is produced. Then, when the number of the strip-shaped print whose finish is the closest to the reference print is input, the correction value corresponding to this is automatically set. The strip print number is printed on the back surface of the sample print by, for example, the back printing device. In this way, for example, in the state in which the printing conditions are changed in 9 levels, the eyeball portion 20, a part of the face images 21 and 22 of the person, the print tint adjustment chart 2
5 and the finished density determination unit 30 are obtained, it becomes possible to set a wide range of printing conditions with one round exposure.

[0035]

According to the present invention, since the background portion of the picture of the normal exposure frame is composed of the gray base portion and a large number of color patterns scattered on the base portion, the sample print By visually comparing the color pattern and the color pattern of the reference print, it is possible to easily grasp the deviation of the color balance. Also, because a large number of color patterns are scattered and arranged, even if processing irregularities occur in the paper processor, it is possible to determine the color misregistration by referring to the same number of other color patterns that are not affected by the color unevenness. Can be performed accurately. Moreover, since a large number of color patterns are scattered, even if processing unevenness occurs, this can be made inconspicuous.

A large number of color patterns have different colors and sizes so that each color pattern is assimilated to the base portion by the combination of these color patterns within the reading range of the light receiving element of the photometric means used for setting the printing conditions in the photographic printer. ，
Since the arrangement is specified, instead of the conventional gray background part,
Reference prints and sample prints in which a large number of color patterns are scattered can be created, and the beauty of these color prints can be enhanced. Moreover, when photometry is performed by a photometric device such as a scanner, these color patterns are assimilated to the gray color of the base portion, so that noise or the like due to the color patterns does not enter the photometric result.

Further, in the case of the normal exposure frame, the eyeball portion is arranged at the center of the normal exposure frame. Therefore, when visual judgment cannot be made, the master balance value using the densitometer is used as in the conventional eyeball negative. Can be adjusted.

A face image of a person is arranged on both sides of the eyeball in a normal exposure frame, the skin color density of one face image is made darker than the standard one, and the skin color density of the other face image is made deeper than the standard one. By making it lighter, it is possible to visually confirm whether or not the finish density is optimum with reference to the skin color density.

Since the normally exposed frame is provided with a finish density determination unit, and the finished density determination unit is configured such that the white pattern and the gray pattern are adjacent to each other on the print obtained by printing exposure of the normally exposed frame, Visually check the boundary of each area pattern of this finished density determination unit,
Whether or not the finish density is appropriate can be easily determined by the degree of clarity of these boundaries. In addition, a print tint adjustment chart is provided for a normal exposure frame, and this print tint adjustment chart is composed of a gray pattern and a plurality of color patterns, and each color pattern is biased by a certain amount with respect to a specific color. Since the tint is developed when the color is applied, the correction amount of the color balance can be easily known by visually determining which of the reference print color patterns the gray pattern of the sample print corresponds to.

The eyeball portion is arranged at the center of the normal exposure frame, and the face image of the person is arranged on both sides of the eyeball portion, and further, it is finished at the vertical center position of one lateral end of the normal exposure frame. Since the print tint adjustment chart is arranged at the center of the other end of the horizontal direction in the vertical direction, the parts are arranged in a horizontal row at the center of the normal exposure frame. Besides, it can be applied to a horizontally long frame such as a panorama frame and a wide vision frame, and can also be used in round exposure.

Further, by arranging a large number of the color patterns of the present invention on the background portion of the conventional eyeball negative, the decorative effect of the reference print and the sample print can be obtained, and whether the color balance is visually deviated or not. You will be able to know easily.
