1. A color grading monitor with LUT (Look-up table) mapping function, for performing LUT mapping to an input image, characterized in that the color grading monitor comprises an LUT storing unit, and further comprises: a receiving module, configured for receiving at least one LUT data or generating LUT data in a specific format according to received operation; an analysis module, configured for analyzing that whether the LUT data meets a predetermined condition, if the LUT data meets the predetermined condition, the received data is updated in the LUT storing unit for a new LUT mapping; if the LUT data does not meet the predetermined condition, the LUT data is discarded, wherein the analysis module compares at least of the data format, data length, and/or data parity information of the received LUT data to corresponding predetermined conditions, and if the data format, data length, and/or data parity information of the received LUT data match the corresponding predetermined conditions, the analysis result is “match predetermined condition”; a transponder module, configured for feeding back analysis results of the analysis module to a control terminal, to determine if it is needed to re-adjust the LUT data wherein, if the analysis result is “match predetermined condition”, the transponder module feeds back a message of “received data is correct”, if at least one of the data format, data length, and data parity information does not match the predetermined conditions, the analysis result is “not match predetermined condition”, and the transponder module feeds back a message of “reception data error”; and a display module, configured for displaying the input image which is updated with the new LUT mapping according to the analysis result from the analysis module.
