Abstract
A gamma correction apparatus includes a load controlling unit, a non-volatile memory, a volatile memory, a checking unit and a counter. The non-volatile memory stores gamma data and a checking code. The load controlling unit controls an operation of loading the gamma data from the non-volatile memory into the volatile memory. The checking unit receives the checking code and detects whether the gamma data in the volatile memory have an error according to the checking code. The counter accumulates the number of times that the checking unit has detected the error. When the checking unit detects the error, the load controlling unit re-loads the gamma data from the non-volatile memory into the volatile memory.
