摘要： An apparatus and method to convert input image data having a first multivalue to image data having a second multivalue which is less than the first multivalue by using a multi error diffusion technique. An image processing apparatus includes a threshold generating device for generating a plurality of variable thresholds at least based on a characteristic of a target pixel data, wherein a number of the variable thresholds is less than a number of the second multivalue by one. A quantization device is provided to quantize the input image data of the target pixel into the image data having the second multivalue based on the variable thresholds. The variable thresholds are varied in a manner such that predetermined quantized data quantized by the quantization device does not create noticeable banding substantially in a middle density range and does not create noticeable dropout substantially in a high density range.

摘要： An image processing apparatus includes a converter, a calculator and a reverse converter. The converter performs a frequency conversion operation on a color image signal which includes a brightness signal and color signals and divides values of each of the brightness signal and the color signals into high frequency coefficients and a low frequency coefficient. The calculator calculates the high frequency coefficients of the brightness signal and the color signals, generates a set of different high frequency coefficients, and produces a new brightness signal by adding the low frequency coefficient of the brightness signal to the set of different high frequency coefficients. The reverse converter performs a reverse frequency conversion operation on the new brightness signal.
