Color measuring apparatus with position adjustment
First Claim
1. An apparatus for measuring color of an object, the apparatus comprising:
- a primary light projector which projects light to an object;
a primary photosensor which senses light which has been projected by the light projector and reflected from the object;
a calculator which calculates a color value of the object based on an output of the primary photosensor;
an angle detector which detects respective angles of the primary light projector and the primary photosensor with respect to the object;
an adjustment mechanism which adjusts the respective angles of the primary light projector and the primary photosensor; and
a controller which controls the adjustment mechanism based on a detection result of the angle detector so that the primary light projector and the primary photosensor come into their respective desired angles.
