Embodiment 1

[0032] Such as figure 1 As shown, the present invention provides a grading monitor 100 for real-time grading of an input image. The color palette monitor 100 includes a LUT mapping unit 10 , a receiving module 20 , an analyzing module 30 , an answering module 40 , an updating module 50 and a displaying module 60 .

[0033] LUT mapping is a bridge connecting different color spaces in the process of color management. Give the LUT mapping module an input value, and the LUT mapping module can return an output value. For example, in a first color space of 10bit RGB, a kind of red is expressed as R=640, G=102, B=94, and this red also exists in another second color space of 10bit RGB, but is Expressed as R=600, G=90, B=145, then the LUT mapping module that converts the first color space to the second color space returns the value after reading the data R=640, G=102, B=94 Must be R=600, G=90, B=145. That is, both the input value and the output value in the LUT mapping unit 10 are ...

Embodiment 2

[0044] refer to figure 2 , the user operation terminal 200a provided by the present invention is basically the same as the user operation terminal 200 provided in Embodiment 1, the difference is that: the user operation terminal 200a includes a color palette 203, and the color palette 203 is connected to the The toning monitor 100a is described.

[0045] In addition, the toning monitor 100a includes a 3D LUT data generating module 201a, an updating module 50a and a display module 60a.

[0046] 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 scroll wheel, slide bar, or button of the color palette 203 in real time information, and generate the...

Embodiment 3

[0051] refer to image 3 , the invention provides a kind of toning method, comprises the following steps:

[0052] Step S301: Connect the user operation terminal 200 / 200a. In this embodiment, the user operation terminal 200 / 200a is connected to at least one of Ethernet interface network, Wifi interface network, Bluetooth interface network, USB interface network, serial interface network, Thunderbolt interface network and 1394 interface network. The user operation terminal 200 / 200a includes color-matching software, and the color-matching software can be PC color-matching software, Mac color-changing software, mobile phone (such as iphone) color-changing software, Android system color-changing software or WP color-changing software. In this embodiment, the user operation terminal in Embodiment 2 or Embodiment 2 is adopted. Of course, the user operation terminal is not limited thereto, as long as it is a device that can provide precise and conveniently controlled human-computer...

Abstract

The present invention relates to a toning monitor and a toning method, the toning monitor comprising: an acquisition module for acquiring 3D LUT data; an analysis module, which is connected with the acquisition module and is used for analyzing whether the acquired 3D LUT data meets a preset condition or not, and if the acquired 3D LUT data meets the preset condition, the 3D LUT data meeting the preset condition is sent to the updating module, and if the preset condition is not met, discarding the 3D LUT data; an updating module, which is connected with the analysis module and used for updating the 3D LUT data meeting the preset conditions and sending the updated 3D LUT data to the LUT mapping unit, wherein the LUT mapping unit is connected with an updating module and is used for performing new LUT mapping on the updated 3D LUT data; and a display module that is connected with the LUT mapping unit and is used for displaying the input image after the new LUT mapping. Through an analysis module and an updating module, correct 3D LUT data is updated to an LUT mapping unit in the toning monitor in real time, and a real-time toning function can be realized through a simple architecture.

Description

[0001] This application is a divisional application of a patent application titled "Toning Monitor and Real-time Toning Method". The filing date of the original application is November 28, 2014, and the application number is 201480002959.7. technical field [0002] The invention relates to the technical field of image processing, in particular to a color-matching monitor and a color-matching method. Background technique [0003] 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 be...
