摘要

PPROBLEM TO BE SOLVED: To provide an image forming apparatus by which high image quality processing can be performed by enabling expansion of color processing space to be used for color processing, and to enable the use of the expanded color space in executing color processing by deciding the color value of pixel to be interpolated when the color processing space is expanded and the image is enlarged. PSOLUTION: The image forming apparatus using a plurality of page description languages is provided with a means for expanding the color processing space in print data, a means for calculating the numbers of interpolation pixels using image data enlarging processing, a bit expansion means for expanding the color value of the input image data according to the color processing expanded by the color processing space expansion means, an interpolation pixel color value deciding means for calculating the color value expanded by the bit expansion means and the color value of the pixel interpolated according to the expanded space to decide stepwise, an image expansion means for interpolating the pixel obtained by the interpolation pixel color value deciding means to enlarge the image data, a means for creating a raster image held as a bit map image from the enlarged image data, and a means for executing color processing using the color processed space decided by the color processing space expansion means.

要解决的问题：提供一种图像形成装置，通过该图像形成装置，能够通过扩展用于色彩处理的色彩处理空间来执行高质量的图像处理，并且能够在执行色彩时使用扩展的色彩空间。通过在扩展色彩处理空间并放大图像时确定要插值的像素的色彩值来进行图像处理。

解决方案：使用多种页面描述语言的图像形成设备具有用于扩展打印数据中的颜色处理空间的装置，用于使用图像数据放大处理来计算插值像素数的装置，位扩展装置。用于根据通过颜色处理空间扩展装置扩展的颜色处理扩展输入图像数据的颜色值的插值像素颜色值确定装置，用于计算由位扩展装置扩展的颜色值和所插值像素的颜色值根据扩展空间逐步确定，图像扩展装置用于对由插值像素颜色值决定装置获得的像素进行插值以放大图像数据，一种用于从放大的图像数据中创建保持为位图图像的光栅图像的装置。以及使用由色彩处理空间exp决定的色彩处理空间执行色彩处理的装置阴离子的意思。
