Abstract:
1. A display apparatus, comprising: A signal input unit to receive an analog image signal; An image processing unit to process the received analog image signal and to output a digital image signal having first color data; A monitoring unit to receive the analog image signal from the signal input unit at a point upstream from the image processing unit, to sense a change in an input level of the received analog image signal, and to sense a change in temperature of the image processing unit that cause the image processing unit to output first color data different than predetermined color data of the digital image signal; and a controlling unit to calibrate the image processing unit according to the change in the input level of the analog image signal and the change in temperature of the image processing unit, respectively, to cause the image processing unit to output the first color data that is the same as the predetermined color data, wherein the monitoring unit senses a change in the input level of the received analog image signal independently of a change in temperature of the image processing unit.
