 Luminance Color Shading Analyzer EyeScale-3W, 4W |
 |
|
|
|
|
Overview
Replacing conventional color and luminance measurement devices, this product captures images with a CCD color camera, and displays the brightness and color shading of the entire display unit as two-dimensional image distribution. This device allows the user to comprehensively evaluate and analyze overall luminance and color shading to the same level as the human eye. |
|
| Features |
 |
Shows absolute values through corrections made by Photo Research Incorporated's PR-650 (spectrometer). |
|
When the camera is pointed at an object, it controls and automatically detects luminance levels to an accuracy of +/-1%, and shows optimum data. |
|
Converts original and luminance distribution images to BMP files. Converts numerical data to CSV files and outputs this data. |
|
Detects very weak luminance differences to a sensitivity of 0.01%, showing "spot unevenness distribution" and "spot unevenness values". |
|
Shows "color difference distribution and color shade rates (ISC-C)" and "luminance distribution and luminance difference rates (ISC-L)" to the same level as the human eye. <Optional> |
|
Shows "bar unevenness distribution" and "bar unevenness rates (ISC-S)" caused by faint changes in luminance. <Optional> |
|
Offers visual angle measurement (+/- 80-degree in 1-degree steps) and high-speed time passage measurement. <Optional> |
