Abstract

PURPOSE:To always execute photograph printing of a large quantity of negative films under a prescribed condition by deriving setting of a printing condition in case of the photograph printing from a mean value of a user by a photograph printing device. CONSTITUTION:First of all, in every developing place, negative films of about 1,000 sheets are measured photometrically by an optical sensor 8, and an average density value Ui (i=R, G and B) is derived in advance at every R, G and B. This average density value Ui is an average value which has added its area and a season. With respect to this average density value Ui, <=0.5 density, >=1.0 density, and an intermediate density are set as an under-negative, an over-negative, and a normal negative, respectively. Also, a light quantity of three colors is adjusted by an area variation or a transmissivity variation by inserting a filter constituted of three colors of Y, M and C onto an optical path 22.

Currently, general photo printing equipment uses standard negatives (negatives with the user's average density value) to print photos.
The printer conditions are adjusted so that the photo printing has a constant density value. However, standard negatives provide a proper relationship between photoprinting equipment and photo paper development, and the average density value of a large number of negatives is used as a way to adjust the photoprinting equipment to correct for the effects of negative development. is known to manage. This management can be performed using the negative film photometer 1G when printing photographs. However, in addition to the complexity of creating standard negatives, standard negatives are usually developed in a standard manner before being supplied to photo labs, and for this reason, the actual negative characteristics and development There is a drawback that it is not created with differences in processing.

In this invention, first, a large number of sheets (for example, 100
0) negative film is photometered using the optical sensor 8, and the average density value U i (i=R, G, B) is recorded for each RGB. This average density value U, is an average value that takes into account the characteristics and processing conditions of the photoprinting device used for the X+lI light, the region, the season, etc., and this average density value U1 is the density value of the conventional standard negative. It is equivalent. Note that the average density value U1 of the negative film may be determined not from the photographic printing apparatus used, but from the national average value or the average value of several photographic printing apparatuses. With respect to the average density value Ui determined in this way, for example, a density of 0.5 or less is set as an under negative U=1.
), a density of 1.0 or more is defined as an over negative (U=2), and an intermediate density thereof is defined as a normal negative (j=3), and the average density value of the three categories is defined as Uth. In the photo printing apparatus using a light control filter as shown in FIG. 1, the filter 2 is composed of three colors of YMC, and is inserted into the optical path 22 to adjust the amount of light of the three colors by changing the area or changing the transmittance. It looks like this. Therefore, the exposure time of the light source 3 is constant. in this case,
The exposure time may be changed depending on the density of the negative film. It is also desirable that the spectral sensitivity characteristics of the optical sensor 8 match or approximate the spectral sensitivity of the photographic paper 6. If they do not match, the spectral sensitivity distribution of the optical sensor 8 and the photographic paper 6 may be used to correct the spectral sensitivity characteristics. It is necessary to keep in mind and always modify the FE before use.

However, the density measurement of the negative film 1 is always based on the amount of light measured by the optical sensor 8 at a constant filter position. Therefore, it is possible to set the filter position at which a constant amount of light is received in the absence of the negative film 1, and then use the value obtained by logarithmically converting the light amount value of the optical sensor 8 at that time to insert a correction paper for the fluctuation of the light source 3. As a result, filter 2 is controlled M (D+ +U
+j), it is possible to provide the photographic paper 6 with an amount of light equivalent to that of a standard negative. In this case, the filter plate 2 of the filter 2 is
Control (D?) 1A to 21G. As a result, standard printing conditions (D1+D2+Uth) for giving a constant amount of light to the photographic paper 6 can be set in the same way as when using a standard negative, and this value is stored in a memory or the like. Then, if the density of the negative film 1 to be printed is determined by the optical sensor 8 and the value is U, then if the control amount of the filter 2 is D3, then U+03=D, ÷D2 "UIJ"
(1) holds true. Therefore, the unknown control amount D3 is D3=D, +02+[Jth-U...
2), it is possible to perform photographic printing by controlling the filter 2. As another method, when the negative film l is U, the control amount D1 + mouth.

It is also possible to drive the filter 2 until it is not equal to UIJ. In this case, filter control and photometry are repeated, and it takes time for convergence, so it is better to combine it with calculation using equation (2).Printing conditions of photo printing equipment Settings are carried out as usual in daily management, and it is necessary to keep in mind the correction amount and control amount a2 to maintain a constant light amount.Please note that the light source fluctuation correction amount must be included in the control amount D2. However, it is necessary to readjust the control amount D2 each time the light source changes (for example, every day).Even if the average density value U-th uses the average value up to the previous day, it is not possible to In addition, the average density value UIJ may be calculated by taking more density points and processing the raw data using smoothing or multiple interpolations. It is possible to manage paper development processing.In addition, the average density value UI
It is possible to monitor the negative development process by monitoring J. Printing using only filter 2 corresponds to a negative film with no contrast, and since the characteristic output slightly differs in the non-linear part, it is possible to monitor the negative development process. It is desirable to modify the above-described method by determining the relationship between the average density and the main part average density for the user negative. In this case, the correction value needs to take into account the gradation of each photographic paper.

On the other hand, a photo printing device with a three-color brightness change method has three light sources of RGB and prints by changing the brightness of each color. It is possible to set In this case, the RGB of the light source
It is preferable to use a band-pass filter as the filter, but if the filter is to be widened due to insufficient light intensity, it is necessary to determine the correction value using the photographic paper spectral sensitivity and the photosensor spectral sensitivity at a constant light intensity. Furthermore, photo printing equipment using a white light attenuation method uses a cut filter to control the amount of RGB light depending on time, and calculates the asymmetric absorption of the power and filter to reduce the amount of RG that is irradiated onto the photographic paper.
It is necessary to focus on the B light, and also consider the reciprocity law irregularities.1ffi L
There must be. For this reason, complicated calculations are required, but if the optical sensor measures light through a YMC cant filter, it is possible to set the printing conditions in the same manner as described above.

(Effects of the Invention) As described above, according to the method of the invention, the setting of the printing conditions for photo printing is taken into account from the user average value in the photo printing apparatus, so differences in development processing, regional differences, and seasonal differences can be set. It can be added to the value. In addition, light corresponding to the user's average value is applied to photographic paper without negative film,
Since the density is controlled to achieve a predetermined density balance, there is no fading or variation, and there is no need to set the printing conditions each time, making it possible to print a large amount of negative film under constant conditions. . moreover,
Since there is no need to create a standard negative or use a standard negative, high efficiency of photo printing can be realized.
