Means for obtaining an image processing condition corresponding to the second image information, performing image processing based on the image processing condition, and obtaining new image information.

At this time, the object to be subjected to the image processing may be the first image information, the second image information, or the third image information having an image size different from those of the first and second image information. For example,
When creating a normal print in which one image is recorded on one sheet of recording paper, image processing is performed based on the image processing conditions obtained for the first image information, and new image information is generated. Prints that print multiple small images on a single sheet of recording paper (such as index prints)
May be applied to the second image information to obtain new image information.

As means for obtaining the second image information by converting the resolution as the conversion of the image size, means for obtaining the second image information by thinning processing or image enlargement / reduction processing such as pixel interpolation may be used. If the image information is already in a file format including images of a plurality of resolutions, there is a means for selecting image information of a desired resolution.

Here, a case where image information obtained by various types of digital cameras (types include a maker, a model, a production lot, etc.) will be described. An image different from the input first image information will be described. Second image information of a size (preferably low resolution) is obtained, and image processing is performed based on image processing conditions corresponding to the second image information to obtain new image information. Thereby, it is possible to homogenize the image quality.

The image information from the digital camera according to the present invention includes one frame of image information from a digital video camera.

The negative film (3) obtained from the film scanner unit 9 for reading image information from the negative film
5 mm, APS, 110 etc. When inputting image information from a different image size, the image information and the second image information obtained by the above-mentioned various digital cameras are converted into the same scheduled image size. (The size may be one or plural) (the image size is not converted in the image processing unit 70 in this case), and the image processing is performed based on the image processing conditions corresponding to the image information. , To obtain new image information. Also, when inputting image information obtained by using the reflection document input device 10, the same scheduled image as the second image information obtained by the various digital cameras described above is used in the same manner as the image information from the negative film. The size is set, and new image information is obtained in the same manner.

The image information (corresponding to the first image information in this case) input from the film scanner unit 9 and the reflection document input device 10 is input to the second
Is set to have the same scheduled image size (one or a plurality of sizes), and the image information having the scheduled image size (in this case, it corresponds to the second image information). The second image information is preferably smaller in image size than the first image information.) Image processing may be performed based on image processing conditions according to the new image information to obtain new image information.

Further, even if the object to be subjected to image processing for obtaining new image information is the image information used to determine the above-described image processing conditions, a new negative film or reflective original is scanned again. Image information (which is preferably higher in resolution than the image information for determining the image processing conditions) obtained from the input image information before the predetermined image size. Is also good. However, when an index print is created from image information from a negative film, it is better to process the image information of the planned size based on the image processing conditions and obtain new image information. It is preferable because the time required for the operation can be saved.

Thus, a negative type color transmission film,
Or, from a positive type color transmission film, or a monochrome transmission film, or image information obtained by reading a reflection original, and image information obtained from various digital cameras, and further, from various media capable of storing computer-readable image information. Image processing can be performed on the input image information with the same processing system.

Alternatively, by performing density correction, the colors and densities of various types of image information can be homogenized.

As described above, various kinds of image information can be input, and these pieces of image information can be homogenized. Further, a high-quality print uniformized from various kinds of image information can be created and an image display means can be displayed. (For example, a CRT).

The color and density can be corrected based on, for example, the average value of the image information. For example, there is a method of calculating a shift amount such that an average value of pixels in one image information becomes R = G = B = 128. This is, for example, a method of calculating a shift amount of a pixel for each color of the low-resolution second image information. If the average value is R = 108, G = 118, B = 138, a correction amount of +20 for R, +10 for G, and −10 for B is set. The correction is to be performed by shifting the value of each pixel of the image information to obtain new image information after the correction.

Further, regarding color correction, see
The color original image described in Japanese Patent No. 61505 is divided into a plurality of blocks, a predetermined first statistic is obtained from the color original image by reducing the influence of the high-saturation blocks, and based on the first statistic,
A predetermined second statistic is obtained by reducing the influence of the high-saturation pixel,

By using a method of reproducing colors from the image, it is possible to perform correction while suppressing the influence of color feria.

Further, with respect to the density correction,
The image characteristics of the original image are calculated from the obtained image information described in Japanese Patent No. 939733, and the characteristics of the original image are evaluated by a linear first-order sum of this image characteristic value and / or a function of the image characteristic value.
By using a method of calculating the exposure amount or the exposure correction amount for the original image by using a regression equation predetermined according to which set of the plurality of predetermined sets of the original image based on the evaluation result, the density It is possible to perform correction while suppressing the influence, which is preferable.

FIG. 5 is a schematic configuration diagram showing another embodiment of the print making apparatus.

The control unit 7 of the print creating apparatus 1 stores image processing conditions for various digital cameras (types include a maker, a model, and a production lot). A storage unit 73 is provided, and the image processing unit 70 performs image processing on the input first image information based on image processing conditions for various digital cameras, which are obtained and stored in advance, and converts new image information. Obtained and sent to the exposure processing unit 4. In the exposure processing section 4, an image is exposed on the photosensitive material, the photosensitive material is sent to the development processing section 5, and the photosensitive material exposed in the development processing section 5 is developed and dried to produce a print. As a result, the image quality of the image information from various digital cameras can be homogenized, and a uniform print can be obtained.

Examples of the image processing conditions stored in the image processing condition storage unit 73 include color, density level shift amount, contrast conversion amount, color matrix coefficient for saturation conversion, and the like. , The corrected image information may be obtained by directly calculating the image information, or the LUT may be set based on the image processing conditions, and the image information may be converted to obtain the corrected image information. In addition, as a method of associating image information from various digital cameras with image processing conditions for various digital cameras that have been obtained in advance, in addition to manually setting by an operator, information of the type of the digital camera is added to the image information. Then, this may be read and set automatically.

As described above, image processing of the first image information based on the image processing conditions is performed using the image processing conditions for various digital cameras, which are obtained and stored in advance, based on the input first image information. It can be performed in a short time, and the processing speed can be improved.

As shown in FIGS. 6 and 7, the CRT 8
Even if the color and density are adjusted manually by operating the operation keyboard 11 of the predetermined touch panel 8a, the image is displayed by synthesizing images of the same image size. There is no need to switch and apply the processing for film images, digital camera images, and the like, thereby simplifying the processing system.

In order to match the aspect ratio of the digital camera image of FIG. 7 with that of the film image, the image is automatically added and displayed in the vertical direction of the image. The above-described image synthesizing process is also preferable because it is not necessary to prepare a print format of an index print according to the type of an input image when an index print including a plurality of images is created.
