The high dynamic range image generation apparatus and method of the single-frame basis is provided. The histogram expansion portion brightness (luminance) different erection distribution for, based on the threshold set for the histogram prior to separation into a plurality of set histograms portions, set a plurality of histogram portion from the original image can expand, each of the source image by photographing a subject It generates a plurality of images having LDR. HDR image synthesis unit synthesizing a plurality of the LDR image to generate a resulting HDR image. According to the present invention, there can be from a single sheet of original image to produce a plurality of LDR image remove the ghosting caused by the movement of the plurality of LDR image synthesized on the subject or imaging device, because the synthesis result HDR image. In addition, to remove the noise generated in the histogram expansion process at the same time to preserve the edge.
