Abstract: PROBLEM TO BE SOLVED: To provide an exposure correction method for improving the quality of a digital image acquired with a no-optimal exposure and taking into account the face that regions, which are important from the perceptive or content point of view, exist in the image. SOLUTION: The method, which is applied directly to the image in CFA (Color Filter Array) format, identifies the regions of the image that are most important from the perceptive or content point of view by means of simple statistical measures. The image is then transformed by inverting then response function is such a manner as to optimize the quality of these regions. COPYRIGHT: (C)2003,JPO

Abstract: A method of processing digital source images, each represented by pixel matrices, to obtain from two or more source images, representing one and the same real scene and acquired by utilizing different exposure levels, a final digital image capable of reproducing the real scene with an exposure latitude greater than that of each of the source images. The method, which can be advantageously used in digital still cameras, produces the final image by combining the source images with the help of a weighted mean constructed pixel by pixel. Thanks to a special filtering to which the weighting coefficients are subjected before the weighted mean operation, the method obtains a final image in which the source images are harmoniously combined with each other. A variant of the method can also be applied directly to digital images in CFA (Colour Filter Array) format.

Abstract: The method involves extracting chromatic information of an image captured by an image capturing device and concerning a human subject, and locating the regions of visual interest. Exposure of the image is corrected by standardization of a grey scale based on the regions. Zones corresponding to the skin of the photographed subject are recognized. The zones are used as regions of visual interests for exposure correction.
