Document Type and Number:
Japanese Patent JP4055866
Kind Code:
B2
Abstract:
A color sensing device of a printing press control system, having a plurality of lamp fixtures (100 and 102) for providing light in the visible region and the near infrared region of the spectrum to illuminate a viewing area (104), a camera assembly (108), said camera assembly having multiple channels to capture images in the visible region and the near infrared region, and at least one lens for generating said images, a calibration target (108) with a uniform light reflectance, a device for adjusting the distribution of said light so that image captured from said calibration target in each channel of said camera assembly is as even as possible, a device for applying a position related compensation process in order to obtain an image which corresponds to a position-invariant viewing condition, and a device for applying a camera value related compensation process in order to obtain an image under a standard viewing condition.
