P‐90: Novel 3D Resolution Measurement Method for Autostereoscopic Display

The resolution of a 2D display can be easily defined by the number of physical pixels. Two‐view autostereoscopic 3D display expresses images by distinguishing pixels directed to the left and right eyes, so the maximum resolution is usually defined as half the number of pixels. However, the resolution of the autostereoscopic 3D display that is actually perceived by the viewer is far less than half the resolution of the number of pixels. Therefore, the resolution of autostereocopic 3D displays must be quantified in terms of perceived resolution. In this study, we studied a method to accurately evaluate sinusoidal patterns with different slanting angles and cycle frequencys using a twodimensional LMD to quantify the resolution of 3D displays. We analyze each measurement image with 2D‐FFT method to define the resolution that the autostereoscopic 3D display can actually express. Finally, the resolution that viewers can perceive was quantified through perceptual evaluation using the landolt ring, and the threshold value that matches the recognition characteristics with the resolution evaluation results analyzed through evaluation was confirmed.
