What does large visual angle mean?

Background: The subtended visual angle of an object is the angle formed by rays projecting from the eye to the top and bottom (or left and right sides) of an object. Visual angles are used to indicate the size of the retinal image of the object — the larger the visual angle, the larger the retinal image size is.

Is spatial frequency the same as spatial scale?

In a sense, this is what visual neurons do at any given location of the retina: different sized receptive fields register image information at different spatial scales (where spatial scale refers to spatial frequency ). The large holes correspond to low spatial frequencies, the small ones to high spatial frequencies.
