Abstract

We performed high-dynamic-range image reduction method with continuous luminance properties by combining images with long and short exposure times.We then used a spatial lter to make a palameter that retains the outline contrast and applied it to a compressed image with a high dynamic range.The retention mask,which consists of a combination of the spatial lter and the original image,retains the low- and high-illuminance sections of the outline.Therefore,unlike with the conventional arti cial retinal processing algorithm,we can retain contrast without outline reinforcement.We achieved image reduction method of high dynamic range with continuous luminance properties without loss of contrast.
