Patent ID: 6917429

Claim:
A color measuring device for measuring color of an illuminated sample comprising: a light dispersing unit for dispersing light reflected by or having passed through the sample, into a plurality of spectral band components; a photoelectric unit for receiving the dispersed light components and outputting electric signals representative of the intensities of the light components; a color measurement value producing unit for producing data of color measurement values according to a predetermined colorimetric system, from the electric signals; a receiver for receiving, from outside of the device, data of an index defining formula defined by a user for converting the color measurement values to a user-defined index; a memory for storing the data of the index defining formula received by the receiver; a first converter for converting the data of the index defining formula stored in the memory, into coded data; a second converter for executing calculation according to the coded data of the index defining formula to convert the data of the color measurement values into data of the user-defined index; and a display for displaying the user-defined index converted by the second converter.
