Description

[Detailed Description of the Invention] (Technical Field of Civilization) This invention provides a pure optical display of an image of an original film such as a negative film, divides the image information of this projected image into pixels, and provides instructions on the screen. This invention relates to a photographic printing system that prints the main subject, etc., on photographic paper to the optimum density.

(Technical background of the invention and its problems) Fig. 1 shows an image information detection device 10 attached to a conventional photo printing device so that image information of an original film such as a negative film is divided into pixels and stored. This shows an example of the apparatus, in which a negative film 2 that is sent along a negative carrier 1 to a printing section has three primary colors of yellow (Y), magenta (M), and cyan (C) for color correction. The light i4 is illuminated through the filter 3 or the blue B, green G, and red R filters 9 for collecting image information, which are inserted alternately with the filter 3. The transmitted light from the negative film 2 that has passed through the filter 3 passes through the lens unit 5 and the bezel 6, and then passes through the photographic paper 7.
It is designed to reach. The photographic paper 7 is wound around a supply reel 7A, and is wound onto a reel 7B in synchronization with the conveyance and stopping of the negative film 2.
Blue (B) is placed near the lens unit 5 side of the negative film 2.

5ity) An optical sensor 8 such as a photodiode for detecting MOGJ photometry C information is provided, and conventionally, a photo is printed based on the detection signal of this optical sensor 8. and.

An image information detecting device 1O is provided near the negative film 2 at an angle to the optical axis LS of the light source 4 and the negative film 2, and a filter 9.
3 and a lens unit 12 for forming an image of the transmitted light whose optical axis is approximately at the center of the negative film 2, and an image processing unit is provided on the back side of the unit-shaped detection device. IC to do? A board [3] on which a processing circuit is mounted is attached.

In such a configuration, when performing normal photographic printing, the filter 9 is removed from the optical axis LS, and the optical sensor 8 detects the transmitted light of the negative film 2 that has been conveyed and is standing still in the printing section. The filter 3 is adjusted by 5N according to the image signal for each BGR of the three side colors, and the black shutter 6 is opened 1.
11. The photographic printing paper 7 is then exposed to light at the exposure value determined.

On the other hand, when detecting and storing image information of the negative film 2 pixel by pixel, the filter 3 is removed from the optical axis LS as shown in FIG. 1 on the optical axis LSk, the negative film 2 is illuminated by transmitting the B, G, and R lights of the white light from the light source 4, respectively.
G, yellow (Y), magenta (corresponding to RPF color)
The image information of the M) or cyan (C) layer is sent to the image sensor 1.
I am trying to input it to 1. Then, by sending a predetermined drive signal from the drive to the image sensor 11, the two-dimensional image sensor 11 receives the transmitted light of the negative film 2 placed in the printing section via the lens unit 12. , the two-dimensional image sensor 11 divides the entire negative film 2 into a large number of aligned small pixels 2A as shown in FIG. 3(A), and scans the scanning lines St,
Accordingly, the entire screen of the negative film 2 can be scanned at rt number. After scanning the entire screen, image signals are sequentially output from the output register of the f-image sensor 11, converted to digital 0, and stored in the memory 2.
5, as shown in FIG. 3(B), the density digital values of the negative fill L, 2 are stored in an array corresponding to the five pixels 21.

In this way, when the digital value f1 for each pixel of the negative film 2 or the C degree f〆1 for each pixel regarding the three primary colors is stored in the memory 25, the digital value is read out from the memory 25 for each pixel of the negative film 2. can be used. Therefore, if density values as shown in FIG. 3(B) are determined and stored for each of the three primary colors BGH, the photographic printing apparatus similar to the conventional one can be used by reading out the stored values and performing processing such as calculation. It can be used for determining or correcting grades. Furthermore, since the image information detection device 10 detects and stores image information by painting the entire screen,
Accurate image information detection can be performed.

In this type of photo printing system, the image information of the original film such as negative film can be divided into a large number of pixels and stored, so accurate information can be obtained as photographic image information. BG image information of original film
Since the information is obtained for each color of H, it is possible to accurately determine the exposure softness and correction extension for photographic printing from this information.

On the other hand, in a photo printing system that assumes mass intensive processing, the original film to be printed is generally tested using a t-test testing device +00, as shown in Figure 4, and the printing section must be corrected based on the testing. If you decide you need a keyboard! 01 to output the correction data to a paper tape, etc. 102 by operating the C degree key, etc., and input the data of this paper tape, etc. 102 to the photographic printer i 200 to correct the exposure value.
This ensures proper photo printing.

However, the reality is that it is difficult to judge corrections using the keyboard 101 unless one is accustomed to some extent, and errors in judgment occur quite often. This is based on the fact that the operator judges the density difference between the subject density and background density of the original film image and the C degree area balance to determine the correction for the LATDI standard. .

(Purpose of IjJ) This invention was made based on the above-mentioned circumstances, and is a method of displaying an image of an original film such as a negative film purely optically, and dividing the image information of this projection into pixels. ,!

(Embodiment of the Invention) FIG. 5 is a diagram showing part 41 of an embodiment of a photographic printing apparatus to which the present invention is applied. In the figure, a mirror 30 that can be rotated between the person position and the B position is disposed between the lens unit 5 and the black shutter 6, and when the mirror 30 is at the 8th position, the negative The negative film 2 is colored yellow (Y) and magenta (
The light transmitted from the negative film 2 passes through a lens unit 5 and exposes the photographic paper 7 to light. The photographic paper 7 is wound up from the feeder roller 7A to the take-up roller 7B, and is transported and exposed in synchronization with the middle frame of the negative film 2, so that the image on the negative film 2 is transferred to the photographic paper 7. It is now possible to print each frame image separately. - On the other hand, when the mirror 30 is in the A position, the image of the negative film 2 is projected onto the pure screen 31 via a field lens (not shown) as necessary. The mirror 30 may be a half mirror, in which case it does not need to be rotated, and the image is projected onto the screen 31 using a separate lens system without passing through the lens unit 5 for forming an image on the photographic paper. Also, a touch panel 40, which will be described later, is layered on the screen 31.

Desired position of the projected image (for example, F, “D” of a person, etc.)
(subject) can be directed from the outside with a finger or the like. .

In addition, a CLS is provided at the side edge of the E surface of the touch panel 40. Morphous silicon, thC? cadmium nitride].

CCD (Charge Coupled Device)
), etc., is moved in the N direction in the drawing by scanning aJ#2s, and by this movement, the projection angle of the touch panel 40 is scanned to detect photographic image information. In addition, in order to prevent damage to the front surface of the line sensor 27 between the touch panel 40 and the touch panel 40, for example, a thin rectangular f-plate is placed in the front surface of the line sensor 27. A 1-1 magnification imaging lens array 28 such as a rod lens array (trade name: SELFOC) in which several hundred glass fibers are arranged in two rows is provided. FIG. 10 shows how the SELFOC lens 281 forms an image, and FIG. 11 shows a SELFOC lens array 2 days in which the SELFOC lenses 281 are bundled and arranged. That is,
SELFOC L.Ns 281 is 1. (It is bonded with one-color resin 282, and held in a sand-like shape on both sides with FRP 283 and 284. A SELFOC lens array 28 having such a structure is arranged in front of the line sensor 27. ing.

As shown in FIG. 6, the scanning mechanism 29 of the line sensor 27 moves on guide rails 291 and 292h arranged parallel to the moving direction, and the scanning mechanism 29 of the line sensor 27
Drive devices 71293 and 294 are provided at both ends of the guide rails 291 and 292F, and these drive devices 293 and 294 run in the N and M directions on the guide rails 291 and 292F. The scanning speed of the line sensor 27 is detected by a speed detector 28. moreover,
If the projected image is a color image, it is necessary to perform image detection by separating the colors into the three primary colors of BGH, so as shown in FIG.
It has a configuration in which three line sensors equipped with 7R are arranged in parallel.

In such a configuration, as shown in :tS8[,I, 1. The licensor 27 is driven by drive signals +01s to +103S from the drive circuit 20, and the licensor 27
The light irradiated to the imaging unit of the image signal P is output from the output register.
The signal is outputted as S, is sampled and held in a sample hold circuit 21 at a predetermined spring/spring cycle, and its bold information is converted into a digital signal O9 by an AD converter 22. The digital signal O5 from the ^/D converter 22 is manually inputted to the logarithmic conversion circuit 23 and logarithmically converted, and after being converted into the cIE signal ON, rQ included 1gX
It is loaded into the memory 25 via the circuit 24. in this case,
The depth control circuit 24 manually inputs the reading speed signal 1 (S) output according to the driving speed of the driving circuit 20 and the speed signal TS from the speed detection = 27 that detects the scanning speed of the licensor 27. By reading the image information for each line corresponding to the reading speed and scanning speed of 27, the projection angle of the screen 31 is divided into a large number of aligned pixels, and the density (n data is stored in the memory 25) for each pixel. It is designed to be remembered.

When the line sensor 27 detects image information of the projection angle of the screen 31, the line sensor 27 is moved in the N direction at a predetermined speed in the scan Ia and the movement 29. The scanning speed of the line sensor 27 by the transport mechanism 29 is detected by the speed detector 28, and the speed signal TS is one;
4 has 3 power. Therefore, when the line sensor 27 is moved in the N direction, the transmitted light from the touch panel 40 layered with the screen 31 on which the negative film 2 is projected by the light source 4 passes through the same-magnification imaging lens array 28 and reaches the line sensor 27. The line sensor 27 outputs an image signal ps that is charged and converted according to the amount of light received by a drive signal from the drive circuit 20. In this case, since the reading speed of the line sensor 27 by the drive circuit 20 corresponds to the pulse frequency of the drive signal, if the line sensor 27 is driven at a relatively high speed relative to the scanning speed of the line sensor 27, the ninth As shown in FIG. 3A, the projection angle of the screen 31 can be sequentially divided into a large number of aligned pixels 40^ by the scanning line SL perpendicular to the scanning direction N. The image signal pS for each scanning line SL from the tee/sensor 27 is input to the sample and hold circuit 21, and the hole toy 1 is converted into a digital signal O5 by the AO converter 22. The digital signal O5 from the converter 22 is converted into a concentration signal ON in the logarithmic conversion circuit 23, and is stored in the memory 25 via the 8-inclusive control 11J path 24. In this case, since the reading speed signal R3 from the drive circuit 20 is input to the one-input path 24, and there is a correspondence relationship between reading and +'S, the density signal DN from the logarithmic conversion circuit 23 As shown in FIG. 9(B), the density data is sequentially stored in the memory 25 at the positions corresponding to the 11 pixels on the screen 31, as shown in FIG. 9(B).

Detection of the image information of the l scanning line SL@ by the T/sensor 27 and storing the density data 1! to the memory 25 as described above. By scanning the entire surface of the screen 31, the density signal ports N are stored in the memory 25 in an array corresponding to the divided pixels 4OA of the screen. This stored data can be freely read and used. In this case, the line sensor 27 is color-separated for each BGR, so if density values as shown in FIG. By reading out the image information stored in the memory and performing processing such as arithmetic operations, it can be used for determining the photographic printing exposure amount or as a correction amount in the same manner as in the past.

Then, when the image information of the projection angle of the screen 31 corresponding to one frame of the negative film 2 is detected by scanning the licensor 27 in the N direction as described above, the image information of the projection angle of the screen 31 corresponding to one frame of the negative film 2 is detected. Data as shown in B) is obtained for each BGR. After this, the line sensor 27 is scanned by the scanning mechanism 29.
may be moved in the M direction and returned, or the next frame may be detected from this position.

When returning the line sensor 27, it is efficient to perform a pre-scan for sensitivity setting etc. on the forward pass, and perform a main scan for image detection on the return pass.

Further, the image signal VS stored in the memory 25 as described above is read out and manually inputted to the correction amount calculation circuit 50, the degree/color correction circuit 51, and the exposure control circuit 52, and the density/color Calculated by the supplementary iE circuit 51. Correction signal D
The exposure control circuit 52 corrects both image signals vS from the memory 25 using C, and drives the filter 3 via the filter drive unit 53 with the determined exposure amount.

Here, if the displayed image is a scene with special conditions such as a backlit scene where there is a difference in brightness between the -L required subject and the background, the main subject will be brightened to achieve the optimum density by making corrections. There is a need. Therefore, in the present invention, by pointing the touch panel 40 with a finger or the like, it is possible to easily specify the main subject in the displayed image, and the pointed position is detected by the related position detection circuit 41. The detected indicated position signal ps is input to the correction amount calculation circuit 50, and the manually inputted indicated position signal P is input to the correction amount calculation circuit 50.
A signal CR is sent to set and correct the image data so that the image data of the corresponding location l has a predetermined photographic paper printing density according to S. The corrected image signal DC°, which has been corrected centering around the main subject data in the density/color correction circuit 51 in this way, is input to the exposure i't/J control circuit 52, where the filter 3 is controlled, and the displayed image is Appropriate printing exposure corresponding to the main subject is performed.

By the way, the touch panel (touch screen, touch sensor, see-through type finger touch input device) 40 allows you to generate a large amount of information by simply touching the screen while looking at one screen. There are digital methods shown in A) and (B), and analog methods shown in FIG. 13 (^) and CB). The digital touch sensor 40 is a first

As shown in Figure (B), two transparent IjI thin II! It is similar to the digital method in that two electrode plates 46, 47 are arranged, but the electrode plates 46, 47
It differs in that it utilizes the uniform conductivity of the contact point to detect current changes at the point of contact. In the analog system, as shown in No. 1314(A), for example, the electrode plate 48.4
A constant current angle yi and a power source 48 are applied to 7, and the upstream 14 generated at one end of the detection resistor 81 of the upper electrode plate 47 is
! The current meter 49A detects the indicated position 1 by measuring the current 12 generated at one end of the detection resistor 62 of the electrode plate 46 with the ammeter 49B. There are various types of touch panels including transparent electrode type, infrared ray, 8 sonic wave, and electrostatic capacitive type, and any of them may be used.

In such a configuration, when image information for each BGR of the original film is normally stored in the memory 25 in the same way as described above, this image information is transferred from the memory 25 as an image signal vS for each BGR for density/color correction iE 1cj1 The characteristic information of the maximum density, contrast, and minimum density records is extracted manually by the method 51, and density/color correction 1E4- 〇〇 is calculated. This automatic correction amount DC is manually input to the dense fog light control circuit 52 to perform exposure control based on the image signal vs.

Here, since the projected image of the pure screen 31 displays the image to be printed, the operator looks at this screen and uses the touch panel 40 to select the required characteristic position (usually an F variable image). Enter instructions accordingly. At this time, through the processing of the correction amount calculation circuit 50, the density/color correction circuit 5! Then, a correction amount CR for setting the photographic paper printing density at the designated position to a predetermined value is added or subtracted from the automatic correction amount DC, and this correction result DC° is manually input to the exposure point control circuit 52. Therefore, by such instruction operations using the touch panel 40, it is possible to obtain the desired image density for printing the main subject on photographic paper. in this case,
The matrix positional relationship between the pixel data storage position of the memory 25 and the touch panel 4o is tth correspondence, and the position (XY address) of the main subject specified on the touch panel 401 is the pixel of the F variable wave subject in the memory 25 or Compatible with image data. The resolution of the line sensor 11 and the touch panel 40 does not necessarily have to correspond l to l in terms of pixels, and the screen is divided at the corresponding position, including surrounding information based on the specified position l. It is sufficient if the image data can be read and used.

The thus determined corrected image signal DC'' is input to the exposure point control circuit 52 into the image signals VS and J (from the memory 25, and the exposure control circuit 52 generates a photographic image with density and color corresponding to the corrected image. The filter 3 is controlled so as to print, and printing and exposure are performed in this state.

As a method for determining the printing exposure star using the automatic correction amount DC, the negative F1 side is divided and image information is obtained individually, and the exposure sensitivity appropriate for the scene is determined from the obtained 71 image information by the method described above. , the average transmission density (LATD) of the screen is Da, the maximum density in the split screen is Dax, and the minimum density is D

In addition, the touch panel 40.1. If you specify multiple positions using I!, the image at that position will be displayed as I! l! If it is continuous and closed, the specified range can be set as the specified range, and if not, the tracking can be performed according to the specified order. Conversely, if the changing wave object is not clear, If the light is evenly distributed over the entire screen, exposure may be controlled using the normal automatic compensation IF; accent Dc without specifying one position.

・On the other hand, since the main subject is often a person, by specifying the position of the face etc. from the outside, the skin color position indicating the person can be accurately detected directly from the pure image data. It is also possible to modify the image data such that the elJIV and color balance of the detected skin color area are set to predetermined values. In this case, since the skin color area often spreads out to a certain size, correction is made using the density at the center of the skin color area as a reference.

Furthermore, when there are multiple skin color areas, the image data is corrected so that the average density of each area is calculated and the average density is set to a predetermined value. In addition, as a skin color detection method, Japanese Patent Application Laid-Open No. 52-158624 and Japanese Patent Application Laid-Open No. 52-1588
There are issues such as No. 25. By the way, the conventional method of skin color detection is
It is extremely difficult to accurately detect the hue due to #ff depending on the light source color, differences depending on the type of negative film, and variations in the development process.If the hue detection range is narrowed, detection will not be possible; When the range is widened, objects (for example, furniture) that have a hue similar to that of an 11:2 subject such as a person and a different skin color component are often misrecognized, resulting in incorrect correction due to processing of the incorrect information. However, as in this invention, the main subject position (person's face)
By specifying from the outside of Pure, it is possible to provide a photographic printing apparatus that can reliably detect skin color with a simple operation and has nine color density correction capabilities with extremely high accuracy.

By the way, as mentioned above, true is a test type z too
It can also be installed and used. That is, FIG. 14 shows an example of this, in which the testing device 100 has a pure screen 110, a touch panel 120 and a line sensor 130 are layered on the screen 110, and the screen of this screen 7.110]- The line sensor 130 detects the density value of each pixel of the image of the R-me test film as described above, and the detected value is stored in a memory section (not shown). In this case, line sensor 13
It is also possible to detect the density value by fixing 0 and transporting and scanning the test film, and then use this test to determine whether printing exposure is required. If it is determined that t needs to be corrected, specify the main subject of the test film image as described above on the screen of the
.

Y address) and the photometric density data stored in the second memory section, the exposure amount is corrected so that the print density at the specified position is optimal. is output to. In this way, the main position of the subject for the image on the film to be printed is indicated as necessary using the touch panel +20 upper
After outputting the corrected exposure 1po corresponding to this position data to -(1 paper tape, etc. +02), the photographic printing device 20
0 as data indicating the position of the main subject and its optimum exposure amount. Therefore, the test type j with the above pure installed
At Jl 100, the exposure amount is determined so that the image data at the location specified on the touch panel +20 becomes a predetermined amount, that is, the print density becomes optimal.

By adopting such a photo printing device and photo printing system, the conventional process of determining correction information for exposure calculations for LATDf average photometry and providing it to the printing device at the time of verification can be reduced to a decision based only on position data. Therefore, the verification process is extremely simple, the 4R of the device is simple, and the signal processing is easy, so it can be relatively easily applied to conventional photoprinting devices and photoprinting systems. In addition, the conventional correction calculation formula for determining the exposure amount does not know the main part of the screen, so it is based on analogy (for example, it is assumed that the main part is statistically located in the center of the screen or in the high-density area). For example, backlighting was often mistakenly treated as high contrast and reversely corrected. This is the exposure T by a pixel-divided image information detection device consisting only of an image sensor.
This was also the limit of IX calculation. Generally normal LA
The print pass rate based on 7D average photometry is approximately Go~7oz9
The pass rate for prints using a pixel-divided image information detection device is approximately 9 oz or higher, and when using a certification device, the pass rate for prints when an advanced person with about one year of experience performs a correction test for LATD average photometry is around 95%. According to this system, even beginners can obtain a print pass rate of almost too high, and there is almost no need for reprinting work due to poor density or poor color tone. Furthermore, although the above-described embodiments have described a photo printing apparatus and a photo printing system, the present invention can be similarly applied to recording on recording media such as magnetic tapes, optical disks, and FJI disk films. .

(Effects of the Invention) As described above, according to the present invention, by specifying the main subject on one screen using a simple operation, the photometric data of that part can be found and calculated, and exposure falsification can be detected. Since it can be corrected automatically, it is possible to obtain a printed photograph with an appropriate print density in the cylinder. Further, even for special scenes such as backlit or backlit scenes, there is an advantage that there is no wastage of photographic paper and processing time due to trial printing for correction of general photometry methods such as LATD average photometry. Furthermore, according to the present invention, there is no need for a CRT shade monitor which is expensive and has space constraints, and since the pure screen, touch panel and line sensor are layered on the same plane, the pixel and pointing position The device is compact and simple, and only special scene bumps that allow the main parts to be reliably recognized need only be located, making it possible to streamline and speed up the verification printing work. In addition, exposure correction of original film for conventional LATD photometry was difficult for anyone but an expert, but with this invention, even beginners can quickly and efficiently test original film very easily. , the workability is good, and the accuracy of exposure calculations is dramatically improved.
