Abstract:
1. A method of reading an image for reading an image signal, which comprises a plurality of image pixels, in accordance with image information from a solid-state detector, where the image information is recorded by exposure to a recording electromagnetic wave holding the image information, the method comprising the steps of: storing a plurality of past image signal read regarding past image information, each past image signal comprising a plurality of past image pixels, which are recorded in the solid-state detector before the image information is recorded in the solid-state detector, and a times T acquiring a time T′ as a time of recording the image information; calculating elapsed times corresponding to each past image signal from times of recording the past image information or times of reading the past image information to the time of recording the image information based on the time T calculating independently certain coefficients for each past image pixel based on the past image signals and the elapsed times corresponding thereto; correcting independently each current image pixel of the current image signal based on the certain coefficients and the plurality of past image signals and elapsed times to corresponding to each past image signal; and reproducing the image based on the corrected current image signal; wherein the elapsed times are not based on a predetermined constant time interval.
