Abstract

The method involves choosing a bold color (13.2) among colors based on distance between an image capturing apparatus and an object of a captured scene for obtaining a digital image. Sharpness of the bold color is reflected on another improved color (13.1). The digital image is decomposed into regions, where the choice of the bold color is carried out for each region. Independent claims are also included for the following: (A) a method of forming a capturing apparatus and/or images restoring apparatus (B) utilization of a digital image`s color sharpness improving method in a capturing apparatus and/or images restoring apparatus (C) utilization of a digital image`s color sharpness improving method in a digital image processing device (D) a digital color image.
