Abstract
A control apparatus for generating a control signal for controlling a printer on the basis of an input signal includes: an arithmetic unit configured to generate an error diffusion processing signal by subtracting, from the input signal, an error diffusion output signal output from a diffusion matrix that determines a distribution of a print density error; a multiplier unit configured to generate an intermediate signal by multiplying the error diffusion processing signal by a correction gain for controlling a correction amount of the print density error; and a quantizer unit configured to generate the control signal by quantizing the intermediate signal.
