Claim:
1. An image processing apparatus comprising: a target value calculation unit configured to calculate a target value, to be output in a predetermined region in input image data, based on pixel values of pixels included in the region; a holding unit configured to hold a threshold value matrix including a plurality of threshold values; a distribution order determination unit configured to determine a distribution order of output values for distributing output values corresponding to the target value in the predetermined region based on a difference between a pixel value of each pixel representing the input image data and a threshold value in the threshold value matrix corresponding to the pixel for each pixel included in the region; and an output value determination unit configured to determine an output value of each pixel included in the region by allocating an output value corresponding to the target value to at least one pixel included in the region in the distribution order.
