摘要： In an optical printing apparatus with employment of a low-cost arrangement, a high image quality recording operation is realized. The optical printing apparatus is arranged by including: image data input device for inputting image data; image data correcting device for correcting the inputted image data in such a manner that a density fluctuation is deleted in correspondence with elements of a print head; reference level producing device for producing a reference level; comparing device for comparing multi-value data outputted from the image data correcting device with the reference level so as to convert the multi-value data into binary data; data transferring device for transferring the binary data outputted from the comparing device as head data to the print head; latch control device for latching data of the print data; and strobe control device for enabling the print head to expose the light therefrom; whereby the print head is driven in response to the output results of the data transferring device, the latch control device, and the strobe control device to thereby form the gradation image. As a result, this optical printing apparatus is capable of forming an image with uniform density in low cost, and furthermore, can correct fluctuations of the elements of the print head in high precision.

摘要： In an optical printing apparatus, an image having a high image quality is desirably produced under stable condition, even when variations occur and exposure conditions are different from each other, which are caused by differences in response speeds of a light source and a liquid crystal shutter element, and also by differences in element driving conditions. The optical printing apparatus is arranged by including: image data input for inputting image data; reference level generator producing a reference level; comparator for comparing multi-value data outputted from the image data input with the reference level so as to convert the multi-value data into binary data; data transferring element for transferring the binary data outputted from the comparator as head data to the print head; latch controller for latching data of the print data; and strobe controller capable of causing the print head to expose the light therefrom. Then, the liquid crystal shutter element corresponding to a non-recording pixel is also ON/OFF-driven. Accordingly, deterioration in the image quality and color shifts, which are caused by a difference in driving intervals, can be solved.

摘要： A recording sheet is fed two times for recording of one line. Two recording operations corresponding to the respective sheet feeding operations are performed in a dispersive manner based on gradation data that are different for the respective sheet feeding operations. For example, binary data for the first and second recording operations are generated by comparing the gradation data with odd-numbered and even-numbered gradation reference values, respectively.

摘要： The present invention relates to a recording and erasing system which uses a thermoreversible medium 1, which can be heated to a first temperature so as to make an image visible thereon, and can be heated to a second temperature so as to make the image invisible. Such a thermoreversible recording medium tends to carry residual images thereon reducing its thermoreversibility after repeated recording and erasing processes. To overcome this problem, the recording and erasing system includes an erasing data generator 7 for varying the energy applied to a heating element so that the recording medium can be heated to a predetermined temperature. The recording and erasing system has an element for checking the usability of the recording medium, thereby preventing use of unusable recording media.
