发明名称 Gray level compensator for picture recorder.
摘要 <p>The invention provides an image recording apparatus for receiving an image signal indicating a density level of a pixel, and for converting the image signal into a modulating signal to modulate a beam light so as to reproduce the corresponding density level on a recording medium. The apparatus includes a conversion table between possible image signals and modulating signals, a correction circuit for obtaining a plurality of correction values each representing a deviation between a current recording characteristic and a desired recording recording characteristic on the basis of the plurality of actual density levels; and a table correction circuit for correcting the conversion table on the basis of the correction value for each of the possible image signals. &lt;IMAGE&gt;</p>
