Method for improving images
A method for producing high-quality photographic images in low-light conditions and in the absence of large-aperture optics. The method includes, upon photographing, first obtaining a plurality of frames of the image with exposures which either partially overlap in time or with an insignificant pause between them. The best result can be obtained in the case when the pause between the exposures represents less than 1/20 of the overall exposure time. The method further includes separating out the initial images from a group of exposures and filtering the images having the smallest exposure interval using the images having the largest exposure interval. The final image is obtained by combining initial images having different exposure intervals from the same group.
1. An image enhancement method comprising:
(a) obtaining a plurality exposures with a low signal/noise ratio,
(b) identification of original images with the best sharpness from these exposures, and
(c) making the final image with a high signal/noise ratio and high definition, by filtering the images with shorter exposure times by using data from the images with longer exposure times.
2. An image enhancement method as claimed in claim 1 , wherein original images are taken from groups of exposures one after another where exposures from the same group either partially overlap in time or the interval between them does not exceed 1/20 of the total time of the exposure.
3. An image enhancement method as claimed in claim 1 , wherein the final image is built through fusion of original images from the same group with different exposure times.
