The previous chapter explained that the human visual system differs from a digital camera in the way it detects and processes color. Our visual system also differs from a camera in its resolution. On a digital camera’s photo sensor, photoreceptive elements are spread uniformly in a tight matrix, so the spatial resolution is constant across the entire image frame. The human visual system is not like that.
This chapter explains why:
Stationary items in muted colors presented in the periphery of people’s visual field often will not be noticed.
Motion in the periphery is usually noticed.
The spatial resolution of the human visual field drops greatly from ...
