发明名称 Method and apparatus for recording image
摘要 A method of image recording comprises the steps of performing photometry on a plurality of pixels into which an original film is divided, calculating the large-area transmittance density (LATD) of said original film on the basis of the photometric values for individual pixels, designating the main area of said original film, calculating the average transmittance density of the designated main area on the basis of said photometric values, determining conditions of exposure as appropriate for said original film on the basis of a linear relationship between said LATD and the average transmittance density of the main area, and performing imagewise recording on a light-sensitive material under the thus determined appropriate conditions of exposure. Using this method, even an unskilled operator is capable of reproducing the image of a principal subject such as a human figure or his/her face to provide an optimum density in an easy and precise manner. Also, an apparatus for image recording applies this method to test printing and needs only a single run of test printing to determine optimum conditions exposure for producing an enlarged print or an ultra-high quality image.
