Abstract:
An image processing apparatus which corrects color pixel data before printing of the color pixel data, the apparatus comprising:an input unit for receiving pixel data on colors constituting an original image having uniform density regions and edge portions;a first converter for converting said received pixel data into color region signals in a uniform color space;a discriminator for determining whether said color region signals belong to said edge portions or whether said color region signals belong to said uniform density regions;a noise removing unit for receiving said color region signals from said first converter and for removing noise from said color region signals which has been determined to belong to said uniform density regions bv said discriminator;a second converter for converting said noise-removed color region signals into pixel data of each color; andan output unit for outputting said pixel data obtained by said second converterwherein said noise removal is executed for improving color print guality of the pixel image data.
