1. An image color calibration processing device applied to a target TCON (Timing controller) chip, comprising:
an acquisition circuit, configured to acquire an image to be displayed, the image to be displayed containing a plurality of pixel points;
a first determination circuit, configured to determine a converted RGB value corresponding to each of the plurality of pixel points according to an original RGB value corresponding to each of the plurality of pixel points;
a second determination circuit, configured to determine a calibration RGB difference value corresponding to each of the plurality of pixel points according to the converted RGB value corresponding to each of the plurality of pixel points and a target look-up table;
a third determination circuit, configured to determine a calibration RGB value corresponding to each of the plurality of pixel points according to the converted RGB value and the calibration RGB difference value corresponding to each of the plurality of pixel points; and
an output circuit, configured to output and display the image to be displayed according to the calibration RGB value corresponding to each of the plurality of pixel points.
