Digital image capturing device and color difference correction method and device of screen

The invention provides a digital image capturing device and a color difference correction method and device for a screen. The method comprises the following steps: providing a to-be-corrected digitalimage capturing device and a to-be-corrected display screen; providing a wavelength-adjustable single-wavelength standard spectrum light source; performing standard image capture; generating an imagecapturing chromaticity correction parameter; completing correction of the digital image capturing device; inputting a standard gray scale signal; correcting the front screen to capture an image; generating a screen chromaticity correction parameter; and completing screen correction. A color characteristic configuration file is built in the standard imaging screen device, and the system correctionparameters generated by the method are recorded in the color characteristic configuration file. And the standard digital image capturing device comprises the image capturing chromaticity correction parameters generated by the m
