摘要： An image reading apparatus individually reads a predetermined white reference plate by flickering light sources of the respective colors before an original image is read by sequentially turning on the light sources during one line sync period. The flickering duty ratio of the light source obtained when the white reference plate is read is set for each color so as to maximize the output value from an A/D converter within its predetermined conversion range. When an original is read, the image reading apparatus changes the emission color by switching the light source to be flickered every line sync period, and turns on the light sources of the respective colors in accordance with different duty ratios set for these colors.

摘要： According to the present invention, when image data are subjected to a quantization processing by an error diffusion method, the generation of a striped pattern which is a cause for the deterioration of picture quality in the error diffusion method is prevented. In the present invention, an original image is read and image data are generated. The image data obtained by reading the original image are quantized by an error diffusion method, and the quantized image data are output and recorded by a thermal-head printer.
Furthermore, according to the present invention, an error between the density of an input image and the density of an output image after subjected to a quantization processing by an error diffusion method is perfectly preserved. In an image processing apparatus for performing a quantization by dispersing an error between input image data and output image data when the input image data are quantized to image data of surrounding picture elements, an error between the input image data and the output image data is operated, the operated error is subjected to a predetermined weighing processing, the error subjected to the weighing processing is dispersed to surrounding picture elements, and a surplus of the error generated at the weighing processing is corrected.
摘要翻译：根据本发明，当通过误差扩散方法对图像数据进行量化处理时，防止了误差扩散方法中造成图像质量恶化的条纹图案的产生。在本发明中，原始图像被读取并且图像数据被生成。通过读取原始图像获得的图像数据通过误差扩散方法量化，并且量化的图像数据由热头打印机输出和记录。此外，根据本发明，通过误差扩散方法进行量化处理之后，输入图像的密度和输出图像的密度之间的误差被完好地保留。在用于当输入图像数据量化为周围图像元素的图像数据时通过在输入图像数据和输出图像数据之间分散误差来执行量化的图像处理装置中，操作输入图像数据和输出图像数据之间的误差对所操作的错误进行预定的称量处理，将经过称量处理的错误分散到周围的图像元素，并且校正在称量处理中产生的多余的错误。
