THE DISTORTION OF LIGHT AND CHROMATIC CHARACTERISTICS OF THE SOURCE CAUSED BY THE RADIATION DIRECTIONAL DIAGRAM
Abstract
Even for an ideal color rendition of color works of art at normal supervision in a case supervision on the big screen or at a view of it at an angle, the aesthetic impression will be inaccurate. It is possible to tell that the distortion of light and chromatic characteristics of a source caused by a radiation directional diagram directly is bound to quality of the image. Approaches to an assessment of influence of the changing spectral distribution of gaged radiation for light measurements are based on calculations of coefficient of activity, can be estimated numerically, they are well developed and standard. It is necessary to offer any approach which will allow to estimate in some approximation influence of supervision under different corners on visual impression.It is apparent that if to make correction of intensity according to the corresponding charts, it is possible to provide an invariance of visual impression. It opens possibilities of correction of the image on the screen taking into account a difference of directional diagrams for every color. Now the increasing number of monitors have the attached or firmware chamber, besides, programs of a face recognition are now widespread.
Thus, it is possible on really measured directional diagrams, using continuous tracking position of the viewer by means of a chamber to calculate necessary correction for obtaining the better image.
Keywords: perception, color image, spectral distribution of an radiation, light characteristic, directional diagrams, chromacity of radiation.
