Abstract: A color correction system and a colorimeter positioning method therefore are provided. A first color block is displayed in a first display area of a display. During the period of displaying the first color block, a first sensing value is acquired for the first color block through a sensor of a colorimeter.

In response to the first sensing value meeting the first specific condition, a second color block is displayed in the first display area of the display. During the period of displaying the second color block, a second sensing value is acquired for the second color block through the sensor. The second sensing value is compared with a second reference value to determine whether the second sensing value meets the second specific condition.
