Colour Matching Results from Two Distinct Observers via a Visual Trichromator System A visual trichromator based on spectrum tunable LED system consisting of control panels was built. The fixed “standard” half-field was white, while the “test” half-field was illuminated by three standard primaries one of which was replaced by a spectrally offset primary. The results from two distin

Prints Clarity Evaluation Indexes Spatial Frequency Response (SFR) evaluation technology to characterize the sharpness of printed images. The slant edge method was used to solve the SFR curve of the prints based on the scanning edge image. In addition, the characteristic frequency and effective characteristic frequency quality indexes of printing SFR were es

Investigation of Parametric Colour Difference on Physical Size Effect for Sample Pairs with Separatiand above 4° field of view (FoV), respectively. An experiment was carried out to evaluate parametric colour difference on different physical sizes using a grey-scale method on a display. 280 sample pairs of display colours were assessed 20 times by 46 normal colour-vision observers (mean age 24?year
