摘要： A photographic printer has an exposure station, in which a frame of a photographic film and color photographic paper are set. A light source is disposed in opposition to the color paper with reference to the photographic film set in the exposure station, and constituted by LED elements. The LED elements are disposed in a matrix for emitting light of red, green and blue colors. The light source illuminates the frame from behind. The color paper is exposed by the light transmitted through the frame, to print the frame recorded on the photographic film to the color paper. In a preferred embodiment, a drive signal is determined individually for driving respective the LED elements. The drive signal is applied to the respective LED elements.

摘要： A method of making photographic prints wherein photographic data relating to photographic conditions of an original frame is recorded on a photographic film at the time of photographing the original frame, so as to determine the print exposure amount for printing the original frame. When it is determined with reference to the photographic data that a primary subject of the original frame has a proper density on the photographic film, the original frame is printed at a basic print exposure amount which is determined without using density data of the original frame. If it is determined with reference to the photographic data that the basic print exposure amount should be corrected for the original frame, an exposure correction amount is calculated based on the photographic data and/or the density data of the original frame. The photographic data is, for example, discrimination data for indicating whether the original frame has been photographed under a proper exposure control, or brightness values measured in a plurality of divisional areas. The photographic data may also be primary subject position data for deriving the density of the primary subject from the density data of the original frame.

摘要： In recording an image on a recording medium such as photographic film, position information used for the detection of a principal image is recorded on the recording medium. The position information is read when a hard copy of the image is produced. A characteristic value is derived from within the area of the principal image detected in accordance with the position information. A print exposure amount used for producing a hard copy is determined in accordance with the characteristic value. The position information may be the information directly or indirectly representing the position of the primary image. The indirect representation may be a combination of a subject distance and a focal length of a taking lens. This combination determines a reference size of a face or figure image on a frame. By detecting an image having the same size as the reference size, the principle image such as a facial image or a figure image can be identified.

摘要： An exposure determining method. Light is measured with respect to a plurality of portions of film images into which images on films to be subjected to printing are divided, thereby obtaining photometric data. The printing exposure condition for a reference film type is corrected with respect to at least one color selected on the basis of the difference in the three color balance of one of the films to be subjected to printing, from that of the reference film type. The exposure is determined on the basis of the corrected printing exposure condition and on the basis of image densities with respect to three colors which are calculated on the basis of photometric data belonging to a specific color region. In one form of the method, items of photometric data are classified by determining to which color regions these items of data belong, certain color regions are selected in accordance with the numbers of items of the photometric data, and the exposure is determined using those photometric data belonging the selected color regions. This makes it possible to determine the correct exposure of an original image formed by photography using a light source different from daylight.

摘要： In printing color films, a color negative film has to be evaluated to determine the amount of exposure. A color balance adjusting apparatus has hitherto been used for appraisal. In the prior art, however, as all the picture images of a color negative film are displayed on a monitor TV for appraisal, it has a demerit in that a speedy inspection cannot be carried out. In addition, as the film picture images are displayed through CRT images of a monitor TV, it is hard on the eyes compared with that by direct visual observation and, therefore, presents a drawback in processing capacity. Accordingly, this invention aims at providing a method which greatly improves the processing capacity of inspecting the color films.

摘要： When printing a photographic film, it is necessary to determine exposure conditions by judging from the conditions of a picture image of an object. However, if the object is analyzed by photometrically measuring it at the developing stage of the negative film, it is impossible to discriminate whether the result of the analysis is attributable to the object per se or the fluctuation in film developing process. According to this invention, a film property printed portion is exposed at a predetermined location on a film beforehand for identification of the film properties, the portion being measured for the density at the time of printing, comparing the measured density with a standard value, correcting the photometrical conditions on both surfaces of the film.
