Abstract
An image recording apparatus according to the present invention is characterized by comprising first signal conversion section for converting a pixel density value of an current pixel of an input image signal into a first recording control signal for defining a recording amount, second signal conversion section for referring to an adjacent-pixel recording control signal for defining a recording amount of at least one adjacent pixel connected to the current pixel to convert the first recording control signal into a second recording control signal, being closest to the first recording control signal, for defining a recording amount at which pixel formation for the current pixel is stabilized, recording section for recording an image based on the second recording control signal, and error diffusion section for diffusing an error between the pixel density value and a recording density value of the second recording control signal to a pixel density value of each of non-processed pixels located around the current pixel.
