Using “Just Noticeable Difference” to Automate Visual Inspection of Displays According to Human Visual Perception

Human perception is the ultimate standard for determining the visual quality of a device. However, the use of human inspection as a quality control method for development or production of devices is problematic because of the statistical variation between observers. In this article, learn how human visual...

Understanding CCD Camera Resolution and Dynamic Range

It is often assumed that a camera with higher resolution and higher dynamic range yields better image quality. Why then do cameras with virtually identical specifications perform so differently? The way specifications relate make undersanding device performance more complex than simple definitions suggest....
