Classification: CPC G | IPC G

Claim 10:
11. An image brightness adjusting device, comprising:
a frame rate predicting/computing device, configured to compute or to predict a first input frame rate according to at least one first input image; and
a brightness compensating device, configured to perform following steps:
(a) generating a first brightness according to a first brightness curve and the first input frame rate, wherein the first brightness curve corresponds to a first frame rate;
(b) generating a second brightness according to a second brightness curve and the first input frame rate, wherein the second brightness curve corresponds to a second frame rate;
(c) generating a first brightness compensating curve according to the first input frame rate and a brightness difference between the first brightness and the second brightness; and
(d) setting a first compensating brightness of at least one second input image according to the first brightness compensating curve.
