A Spectral Characterization Calibration Method and Device for Output Equipment

Abstract

Embodiments of the invention provide a spectral characteristic correcting method and device for output equipment. The method comprises the steps of correcting conventional parameters corresponding tothe output equipment to obtain parameter correction information; correcting a mechanical dot area and an optical dot area of the output equipment to obtain corrected dot areas; obtaining a theoreticalspectral information value according to the corrected dot areas, and optimizing a correction factor according to the theoretical spectral information value and an actual spectral information value ofan original manuscript to obtain a corrected spectral information value; and constructing a characteristic file according to the parameter correction information, the corrected dot areas and the corrected spectral information value, thereby realizing the correction of the output equipment. The device is used for executing the method. According to the spectral characteristic correcting method anddevice, the metamerism phenomenon can be greatly improved through the characteristic file, so that the visual observation effect that an output image keeps high consistency with the original manuscript under any observation condition is guaranteed.

Description

technical field [0001] The invention relates to the technical field of color reproduction, in particular to a method and device for correcting spectrum characteristics of an output device. Background technique [0002] In recent years, more and more consumers choose to use traditional Chinese calligraphy and painting works to decorate their home environment and office space, resulting in a sharp rise in the demand for calligraphy and painting works. Compared with such a large market demand, the number of authentic works is insignificant. In this situation where the relationship between supply and demand is extremely mismatched, the high-simulation reproduction technology of artworks based on spectral information came into being. [0003] Relevant scholars at home and abroad have proposed a variety of spectral-based prediction models, spectral reflectance reconstruction models, and spectral color reproduction processes: spectral image acquisition technology, spectral image pr...

Problems solved by technology

However, there are still a large number of disadvantages of "metamerism" replication that cannot be effectively avoided, making it difficult to maintain visual consistency after changing observation conditions, so it is difficult to achieve accurate replication of spectral images
