Aptina Developed Image Quality Measurement Ruler

SPIE: Aptina has developed a softcopy ruler method to measure image quality. It enables the calibrated visual assessment of image quality. Because the assessments are measured in just noticeable difference (JND) units, it is possible to combine measurements of different attributes and predict overall quality. The method was developed during phase 2 of the Camera Phone Image Quality Initiative sponsored by the International Imaging Industry Association (I3A).
