    摘要： An image reading apparatus includes a diffusion box unit comprising a plurality of diffusion boxes, which each correspond to different sizes of photographic films, and controls the unit in such a manner that the diffusion box, which corresponds to the size of a film whose image is to be read, is positioned on an optical axis of a light source. Accordingly, the responsibility imposed upon an operator can be reduced and the error of choosing a wrong diffusion box can be prevented.

    摘要： A method of correcting the light amount irregularities for a photographic printer in which an image displayed on a two-dimensional display unit is exposed by transmitting or reflecting the light from a light source through or from the two-dimensional display unit is disclosed. An LED light source is turned on with a predetermined driving voltage applied to all the pixels of a liquid crystal panel. The image on the liquid crystal panel is exposed for a predetermined length of time by the light transmitted through the liquid crystal panel and developed thereby to produce a photographic print. The density at a point corresponding to each pixel of the liquid crystal panel is measured. The light transmittance correction amount for each pixel of the liquid crystal panel is determined in such a manner that the density measured at each point conforms to a predetermined reference density (a minimum value of density measurement, for example). The driving voltage correction data for each pixel of the liquid crystal panel is calculated on the basis of the light transmittance correction amount thus determined.

    摘要： When negative images on a negative film are stored in a negative image storing unit, an index print image is constructed by an index constructing section in an image processing unit on the basis of the inputted images, which is displayed as a positive image on a monitor through a display instructing section. Images having different top-to-bottom directions in each of lateral and vertical image groups are indicated by key operation on a keyboard connected to the image processing unit with respect to the index print image displayed on the monitor. The direction of the indicated image is changed by a direction changing section in the image processing unit, and then the image is displayed on the monitor again. An index print image after changing the direction is displayed in an index printing section (on a liquid crystal panel). Thus an index print is prepared.

    摘要： The present invention provides a photometric unit designed for a photographic projector-printer assembly, which does not require a movable portion and is thus simple in its structure and eliminates any time lag in focal length change. The photometric unit 20 is diagonally offset with respect to the projection-side optical axis and has two area sensors 9 and 10 mounted in parallel with each other on a common substrate plate 8 and two image-formation lenses 11 and 12 having different focal lengths, which are located in operative association with the two area sensors. The optical axis a of one image-formation lens 11 having a longer focal length is positioned such that it intersects the optical axis of the projection optical path at a point O on the negative film, whereby a negative film image formed on either one of said area sensors depending upon the size of the image on said negative film is photoelectrically converted for photometry measurement.

    摘要： An image reading apparatus and method in which no complicated control is carried out and suitable adjustment of the color balance can be carried out in accordance with the type of a photographic material. First, the type of a photographic film to be read is acquired. When the photographic film is a negative film or a sepia-tone film, a filter for negative film is set on an optical axis of illumination light. When the photographic film is a positive film or a black-and-white film, a filter for positive film is set on the optical axis of illumination light. In either state, a film image on the photographic film is read.

    摘要： An image reading apparatus and method is realized which can obtain light correction data with accurately and without involving a complicated operation. A turret including balance filters for a negative film and for a positive film, respectively, is provided in the image reading apparatus. When light correction data is acquired, the turret is controlled so that the positive-film balance filter is inserted and located on an optical axis L of light emitted from a lamp, and in a state in which a photographic film is not set in a film carrier, light correction data is generated based on image data outputted from a line CCD. At the time of reading images on the photographic film, when a negative film is used as the photographic film, the negative-film balance filter is inserted and located on the optical axis L, and when a positive film is used as the photographic film, the positive-film balance filter is inserted and located on the optical axis L. Further, light correction is performed for image data inputted from the line CCD using the above-described light correction data.
