AN IMAGE PROCESSING METHOD AND DEVICE

摘要

An image processing apparatus and method provides raster image data with light point enhancements. In one aspect the apparatus generates first raster data in a first geometric domain and second raster data in a second geometric domain. The apparatus transforms the first raster data from the first domain to the second domain and combines the transformed first raster data with the second raster data. In another aspect the apparatus has an attenuation unit which applies attenuation to the first raster data. The attenuation is applied dependent upon second raster data. The combination of the transformed first raster data and second raster data provides enhanced contrast, colour representation, and preserved spatial positioning of the second raster data within the background image provided by the first raster data.
