Abstract

FIELD: information technologies.

SUBSTANCE: according to the method, screen matrix is periodically scanned, colour signal of each matrix element is transformed, which belongs to a complete colour palette of video material, into a signal, which codes the according colour with an order number i, which belongs to a specified limited colour palette from N basic colours, and at the same time a signal is sent into the i counter from a group of N counters. On completion of video material the signal of sum of each of N counters is transformed into a signal of percentage content of appropriate colour of limited colour palette in the whole video material. On the basis of the last produced N signals a colour histogram is built, printed and copied, and then glued onto a case of video material carrier, and it is inserted into the analysed video material in digital format on the video material carrier, and also into the electronic base of colour certification of video materials.

EFFECT: provision of demonstration of video material colour content.

Description

The invention relates to the field of labeling of storage media intended for reproduction, in particular to an additional classification (color certification) of video materials (films, television shows, computer games, illustrated books, etc.) for their psychophysiological effects on the viewer.

Known methods for marking machine-readable storage media intended for playback. In particular, a method for such marking is known (application for invention of the Russian Federation No. 2006104026/28 dated June 17, 2004, published on September 20, 2007 Bull. No. 26), based on an insert, for example, in a video material on a data carrier of a sequence of specialized labels that individualizes the medium. This method does not allow to indicate the color content of color video materials due to the lack of analysis of the color content of video material and an electronic database for color certification of video materials.

At the same time, a method is known (application for a patent of the Russian Federation No. 2004133620/09 dated November 17, 2004, publ. March 20, 2006 Bull. No. 8, adopted as a prototype of the invention) of applying to a serial product, including a data carrier with video material, a unique, visually recognizable machine-readable marking using an electronic database for storing markings of serial products. In this case, marking is made including in the form of a label. The disadvantages of this method is the other purpose of marking, in particular, intended to protect against unauthorized copying, that is, the lack of color certification of the video material and, therefore, the sequence of manufacture of the label for color certification of the video material.

An object of the present invention to produce a color label is to demonstrate the color content of the video material.

The problem is solved as follows. First, a simplified color palette of N colors, for example, N = 8 or more (up to 29), is selected for all video materials. For a specific video material, when it is played, the screen matrix is periodically scanned. In this case, the color signal of each element of the screen matrix belonging to the full color palette of the video material is converted into a signal encoding the corresponding color with serial number i, belonging to a given limited color palette of N basic colors, and an increment signal is sent per unit to the ith counter from the group N counters. At the end of the video material, the sum signal of each of the N counters is converted into a percentage signal of the corresponding color of a limited color palette in the entire video material. Based on the last of these N signals, a color histogram is built, printed and copied, which is pasted onto the case of the video material carrier and digitally inserted into the analyzed video material on the video material carrier, as well as in the electronic database of color certification of video materials.

The color label thus obtained demonstrates the color content of the video material and allows: firstly, with the help of specialists (psychologists, physiologists, and so on) to determine the psychophysiological effect of the video material on the viewer at a subconscious level; secondly, to help the consumer of the video material to make the right choice of video material for viewing, taking into account individual color preferences.

Consider the proposed method in more detail.

To implement the proposed method, first choose a limited color palette of N, for example, from 8 (12, 16, 22, 29, etc.), colors and a special way to convert a color signal from a full (standard) color palette, for example, from 16 million colors, to a color signal of the selected limited palette. For example, the entire signal spectrum, which, according to the original full color palette, forms all shades of blue, corresponds to only one i-th signal of a limited color palette of 8 colors (red, orange, yellow, green, cyan, blue, violet, black), in this case - the sixth, denoting blue. In short, we will call such a special method (requiring separate patenting) of the PCB. To get a color label, a standard video player is launched. Simultaneously with the inclusion of playback of certified video material, the proposed method for producing a color label is used. At the same time, for each video frame, the image matrix rows are scanned by the color analyzer and the color signal of each row element is obtained in each of these lines, and the signal corresponding to the color number in the selected limited color palette corresponding to the original color signal of this element of the image matrix row is received by the DSP. An increment signal per unit is sent to the ith adder (out of the total number N of adders) corresponding to the received signal, denoting the color number i of the limited color palette. Thus, as a result of the analysis of all frames of the video material, the total values of the presence of each color of the selected color palette in the entire video material are obtained. Further, based on the amounts obtained, for example, a pie chart is formed, which is displayed on a printing device, that is, a colored label is obtained, copied if necessary, and then glued onto media and / or media cases of the analyzed video material. Also, this pie chart in digital form or in the form of several image frames is included in the analyzed video material, as well as in the electronic database of color labels for video materials. Thus, the desired color label is obtained that demonstrates (characterizes) the presence of the colors of the selected palette in the certified video material.

The color label allows the consumer of video materials to choose, depending on their individual inclinations, the video material that according to the color label contains the largest proportion of the colors that the consumer needs. In addition, specialists psychologists, physiologists and others determine the corresponding psychophysiological effect of the video material on the consumer by the color label, which further orientates the consumer to view or refuse to view the video material.

The electronic database of color certification of video materials, such as movies, allows you to classify them and provides the ability to issue recommendations for viewing to viewers with various psychophysiological data.

In view of the described, the claimed effect is achieved: the color label produced by the presented method demonstrates the color content of the video material, that is, provides its color certification.

The claimed technical solution is not obvious, introduces a new quality in the evaluation of video materials, and its technical level is quite high.

The possibility of industrial application of the invention is not in doubt, since:

- the method is intended for use in specific sectors of the economy using video materials, for example in the production and rental of films, television films and other television broadcasts, computer video games and the like;

- the implementation of the method is possible using the technical principles described in the application;

- the method ensures the achievement of the claimed technical effect;

- the method is technological in execution, since it uses modern computer and office equipment, including computers with multi-core processors, television and video equipment, printing devices (printers, including specialized ones), electronic databases and printing equipment for mass production of color labels.
