[0017] see figure 1 , which is a functional block diagram of the toning monitor 100 provided by the first embodiment of the present invention. The toning monitor 100 is connected with a user operation terminal 200 . The grading monitor 100 has a real-time grading function, and the function is used for real-time grading of an input image. In this embodiment, the user operation terminal 200 includes color matching software, and the color color software can be PC color color software, Mac color color software, mobile phone (such as iphone) color color software, Android system color color software or WP color color software. color software. In other embodiments, the user operation terminal 200 may also be a color palette (described in detail in the second embodiment). Of course, the user operation terminal 200 is not limited thereto, and any device capable of outputting 3D LUT data can be used as the user operation terminal 200 .

[0018] The user operation terminal 200 includ...

[0028] see figure 2 , the grading system 200a provided by the second embodiment of the present invention is basically the same as the grading monitor 200 provided by the first embodiment, the difference is that: the user operation terminal 200a includes a grading table 203, and the 3D LUT data generates Module 201a is integrated in toning monitor 100a. The color palette 203 is connected to the color palette monitor 100a via a USB data cable.

[0029] Specifically, the toning monitor 100a includes a 3D LUT data generating module 201a, an updating module 50a and a display module 60a.

[0030] The 3D LUT data generating module 201a is used for the signals transmitted from the color control console 203 to generate 3D LUT data. The palette can be a keyboard and / or a mouse. In this embodiment, the user operates the scroll wheel, slide bar, or button of the color palette 203 according to his own color matching requirements, and the 3D LUT data generation module 201a reads the scr...

Abstract

The present invention discloses a color modulation and a real-time color modulation method for conducting real-time color modulation for input images. The color modulation herein includes a Look Up Table (LUT) mapping unit, an obtaining module for obtaining 3D LUT data, an analysis module for analyzing the obtained 3D LUT data and determining if the obtained 3D LUT data qualifies preset conditions, and a display module for displaying the input images which have undergone a new LUT mapping, wherein if the obtained 3D LUT data qualifies, the obtained 3D LUT data will be updated to the LUT mapping unit and the new LUT mapping will be conducted; if not qualifies, the 3D LUT data will be abandoned.

Description

technical field [0001] The invention relates to image processing, in particular to a color-matching monitor and a real-time color-matching method. Background technique [0002] In today’s digitized film technology, images will go through different systems from image acquisition to final projection. film, and finally projected onto the screen through a projection system. Each system has its own unique color space, that is to say, the performance of the same image in different systems is different. The task of color management is to understand the characteristics of the color spaces of these systems, so that the color spaces of different systems can be unified . To put it simply, it is necessary to ensure the consistency between the images monitored during the production process and the final screen images. [0003] Generally speaking, the process of color management can be regarded as the process of converting colors between different color spaces. If no correction is mad...
