Two-dimensional color measuring device, two-dimensional color measuring system, and two-dimensional color measuring method

摘要

The imaging unit captures a color image of the screen (two-dimensional light emitting area). The optical sensor unit outputs a signal indicating the color of a predetermined measurement point included in the screen. The first correction is to correct each tristimulus value at a plurality of measurement points included in the screen using the tristimulus value at a predetermined measurement point. The second correction is to correct each tristimulus value of a plurality of measurement points included in the screen using a predetermined correction coefficient. The correction unit executes the first correction when it is determined that the screen is in the bright state, and executes the second correction when it is determined that the screen is in the dark state.
