Abstract
In a tone conversion apparatus, a decision-processing section sequentially detects a signal level difference between pixels of an image in a predetermined direction thereof by using the image signal having a first number of bits, determines whether the signal level difference remains within a preset signal level difference, and determines a pixel which has the same signal level as that of an immediately preceding pixel that encounters the signal level difference and is consecutive with the immediately preceding pixel. A bit-allocation-processing section may also be utilized.
