    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： 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： 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： A condition-setting method for a photographic printer is disclosed, which is capable of performing the condition-setting work both simply and rapidly. In setting conditions for a digital exposure section, a single condition-setting image data having added thereto a correction value for the condition-setting process that has been performed at a surface exposure section is produced by an image signal processing section and stored in an image memory. A subsidiary control section sets an exposure time for the digital exposure section on the basis of the condition-setting image data stored in the image memory. The conditions need not be set for the digital exposure section using a plurality of Bull's eye negative films having different negative film densities, thereby simplifying the condition-setting job.
