1. An image correction circuit comprising: a luminance correction means for performing luminance correction on input image data; and a color correction means for performing adaptive color correction on input image data on the basis of the following formula (1): 
 Cout∝Cin×[1+M×(Δ Y/L)]  (1) where Cout represents a chrominance signal after color correction, Cin represents a chrominance signal before color correction, M represents an adaptive color correction magnitude which is a fixed positive value, Δ Y represents the total amount of luminance correction by the luminance correction means, L represents a fixed positive value satisfying L<(Ymax/2), and Ymax represents maximum luminance of input image data.
