To provide an image processing method, an image processing apparatus, and a projector which determine a scene-change so as to perform an optimal tone conversion, luminance correction, or the like, for each scene of a moving image. [Solving Means] An image processing apparatus 100 includes a normalized-luminance-histogram computing unit 101 for computing a normalized luminance histogram for each frame, histogram buffers 201a and 201b for storing normalized luminance histograms of respective comparing frames, a scene-change-detecting reference-value computing unit 102 for computing scene-change-detecting reference values alpha and beta corresponding to correlations between two normalized luminance histograms of the first and second frames respectively stored in the histogram buffers 201a and 201b, and a scene-change determining unit 103 for determining whether a change in scenes between images of the first and second frames has occurred or not, in accordance with the scene-change-detecting reference values alpha and beta.
