An image recording apparatus includes a PLZT head. The PLZT head performs an interval exposure based on an interval exposure data between exposures of photosensitive material. Further, exposure data of a predetermined number of lines already used in an N-th and preceding exposures may be maintained in a RAM as a basis of correction to an exposure data for an N&plus;1-th print. The PLZT head performs an exposure for an exposure time given by the corrected exposure data.

Image recording apparatus and image recording method

In an image recording apparatus, exposure light amounts measured by a sensor immediately after a PLZT head performs an exposure with exposure light amounts corrected first by a controller using an original scanner or the like are stored in a memory as correction reference exposure light amounts. Thereafter, the controller performs an exposure correction such that the exposure light amounts measured by the sensor agree with the correction reference exposure light amounts. At this time, since the correction reference exposure light amounts are set according to the precision of the sensor, a shortage of the exposure light amount can be easily recognized by comparing both exposure light amounts even if the precision of the sensor is not high. As a result, the exposure correction can be reliably performed. Accordingly, the exposure light amounts can be accurately corrected even when using a sensor having a relatively large scanning displacement. As a result, the price of the image recording apparatus can be reduced.

An image printer includes a projection exposure unit for projecting and exposing a film image on to a photosensitive material, an image exposure unit for exposing the photosensitive material based on exposure image information with setting an exposure amount for each of a plurality of areas, an image reader for reading information of the film image with the information being divided into a number of areas, and a correction-information instructing unit for instructing correction information for correcting the image information read by the image reader. The image exposure unit generates the exposure image information based on the image information read by the image reader means and on the correction information instructed by the correction-information instructing unit.

An image printer includes a negative-film projection exposure unit capable of projecting and exposing image information of a negative film on to a photosensitive material adapted for negative films and a positive-film exposure unit capable of exposing image information of a positive film on to the photosensitive material adapted for negative films.

A photographic printing and developing apparatus includes an exposure section in which a standard exposure is effected on a photosensitive material under predetermined conditions in a manner similar to that for preparing a conventional control strip. The apparatus further includes a device for measuring the density of the developed photosensitive material, and a device for displaying the condition of the processing solution which is determined based on the measured density. A negative film is prepared for the standard exposure. The apparatus is provided with a control section which selectively uses different light sources for ordinary printing and for the standard exposure. The control section reads in the measured density of the photosensitive material after the developing process, and calculates the condition of the processing solution based on the measured density. It is judged whether or not the condition of the processing solution is within a usable range, and the results of judgment are displayed.

Photographic printing and developing apparatus

An image exposure system for printing an image, comprised of pixels, on photosensitive media based on image data, includes an exposure unit for converting the image data into a light signal for exposure of each of the pixels, a measuring device and a compensator used to correct exposure levels. The exposure unit has light output elements for outputting the light signal for respective ones of the pixels onto the photosensitive media to effect exposure of the image on the photosensitive media. The measuring device is for measuring a density of each of the pixels of the image on the photosensitive media produced by exposing the photosensitive media with reference image data as the image data. The compensator corrects exposure levels of the pixels based on density data obtained by the measuring device, using the density data of a darkest one of the pixels as a reference to reduce differences between the exposure levels produced by respective ones of the output elements caused by changes in output characteristics of the exposure unit. The construction of the exposure system provides for compensation of changes in the light output elements without increasing the size of the exposure unit.
