Abstract

The present invention provides an image display method and an image display apparatus, which solve the three-dimensional cueing confliction problem of the maximum intensity projection in the stereoscopic display method, while enabling users to select and render with emphasis the maximum intensity projection of the objects of interest, so that to realize the stereoscopic display. In accordance with the present invention, a three-dimensional surface which has equal distance to a sight-point is utilized as a reference surface, and the distances from all of the local maximum intensity points to this reference surface are calculated, then, the weighting factor of each local maximum intensity point is calculated according to the distances and predetermined weighting function, afterwards, the values of local maximum intensity points are adjusted according to the obtained weighting factors, and finally, the maximum intensity projection value is produced by synthesizing all of the adjusted values of local maximum intensity points.
