Abstract

PROBLEM TO BE SOLVED: To process color correction or the like most suitable for received image data in the photographic image recording device. SOLUTION: A data set recognition section 3 receiving image data (NSK TIFF signal) decides which data set to be a choice. A character string recognition section 4 selects a set recording correction (color correction or the like) curve corresponding to a set character string when a character string inserted to each data set is coincident with the set character string. After the received image data are processed for color correction or the like according to a recording correction curve to be selected, a recording section 2 records (prints out) the image data.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic image recording device, and more particularly to a photographic image recording device with a color correction function.

[0002]

2. Description of the Related Art There is an increasing need to record color or monochrome photographic images having multi-value gradation in the luminance direction. As the recording unit, for example, a sublimation type thermal transfer printer or the like capable of recording multi-value gradation is mainly used. As the system configuration, for example, image data transmitted via an analog public line or a digital line such as the INS net 64 is received and recorded. Recently, there is also a configuration for connecting to a LAN (local area network) or the like.

The sublimation type thermal transfer printer has a feature of being able to record multi-value gradation image information, but the gradation characteristics (linearity, dynamic range, etc.) are not sufficient, and the material of sublimation type toner and recording equipment. Affected by the characteristics of.

Not only that, but also the characteristics (gradation and color) of the image data sent are influenced by the characteristics of the image pickup camera, the image scanner, etc. for picking up the image data, so that the correction characteristics (method) are changed. There are many things and they are not standardized at present.

Particularly with respect to color, since the position on the chromaticity diagram varies depending on the type of toner, color correction processing is extremely important. Therefore, the color correction of these image data and the correction of the brightness such as the correction of the gradation relationship will be referred to as color correction processing hereinafter.

In Japanese Patent Laid-Open No. 7-303190, the model code of the transmitting device is added to the image data to be transmitted on the transmitting side as control data, and the model code of the transmitting device is separated from the received image data on the receiving side. A method has been proposed in which color correction processing data corresponding to a model code of a transmitter registered in advance is read, and the received image data is subjected to color correction processing by the read color correction processing data. There is.

[0007]

However, the processing such as color correction is not limited to the model of the transmitting device, but is fixedly submitted in the daily operation such as the version number of the transmitting device and the type of image (weather chart, etc.). The processing such as color correction differs depending on the image close to the value image, the photographic image having multi-value gradation, the camera image, etc.), and the proposal described in JP-A-7-303190 is not sufficient.

An object of the present invention is to provide a photographic image recording apparatus capable of performing the most suitable processing such as color correction for received image data.

[0009]

A photographic image recording apparatus according to the present invention comprises a control data detecting means for detecting control data added to received image data, and a correction curve for storing a plurality of recording correction curves in advance. A storage means, a correction curve reading means for reading a recording correction curve corresponding to the detected control data from the correction curve storage means, and a correction processing of the received image data by the read recording correction curve and recording. And image data recording means for performing the same.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The operation of the present invention is as follows.
As control data, NSKTIFF (Nihon Shinbun Kyokai Tag Image) established by the Japan Newspaper Association, which is a digital photographic transmission format mainly used by newspaper companies and the like.
It is called a data set such as a service ID (enter the company name of a newspaper company or a news agency), a generation medium (a device name that generated image data), a generation program version, etc., which is included in the File Format; The thing is used to perform processing such as color correction of image data.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of a photographic image recording apparatus according to the present invention.

In FIG. 1, the photographic image recording apparatus comprises a data processing unit 1 and a recording unit 2 which are, for example, personal computers, and the data processing unit 1 includes a data set recognizing unit 3,
It is composed of a character string recognition unit 4 and a recording correction curve setting unit 5. The recording correction (color correction, etc.) curves are set in advance as needed and stored as the recording correction curves 12 and 13 as shown in FIG. 2 in correspondence with the image conversion characteristics on the transmitting device side.

From the received NSK TIFF signal, the data set recognition section 3 determines which data set is to be selected. There may be multiple choices. In the character string recognition unit 4, when a character string inserted in each data set and a preset character string match, the stored recording correction (color correction, etc.) corresponding to the set character string is performed. ) The curve 12 or 13 is selected, and the received image data (NSK TIFF signal) is subjected to color correction processing by the selected recording correction curve and then recorded (printed) in the recording unit 2. To do.

When a plurality of data sets are set, the logical product is used to select the recording correction curves 12 and 13.

In the example of the output condition setting of FIG. 2, NEC9 is used as the character string of the data set generation medium 6, and Ver (1.0) is used as the character string of the generation program version 7.
At 10, it indicates that the recording correction curve 12 is set. In addition, the character string of the data generation medium 8 is NEE.
At C11, the recording correction curve 13 is set.

As the data set to be set, a data set (1:30 service ID), company name of newspaper company, news agency, etc. is inserted, data set (1:40 envelope number) serial number of each device, etc., data set (1 :
50 product ID) Required for each company's necessary information, Dataset (2:15 categories) First identification of photo category, Dataset (2:20 Supplemental category) Second identification of photo category Subdivision identification, data set (2:22 fixed identifier) Identification of photographs that are fixedly posted in daily operation, data set (2:65 generation medium) device name that generated image data, data set (2:70) Generation program version) etc. are considered.

[0018]

As described above, according to the present invention, it is possible to automatically and finely set the recording correction curve that is suitable for the image conversion characteristic on the transmitting device side, and it is possible to perform high-quality recording (printing).
