Abstract
An image data processing apparatus includes a plurality of registers each of which outputs an output signal in accordance with a corresponding signal of a plurality of input coincidence signals derived from the input image data, the output signal indicating whether or not a corresponding register has a maximum count value, and each input coincidence signal indicating whether or not a corresponding pixel among neighborhood pixels of a target pixel of the input image data coincides with a corresponding dot among predetermined reference dots at given locations relative to the location of the target pixel in the input image data, and a state checking part for outputting a state signal indicating whether or not the output signal level of a first register having the maximum count value currently changes from the previous level by detecting the current output signal level of the first register in accordance with the input coincidence signals and in accordance with the output signals of the registers.
