visual angle

In the vision sciences it is called the visual angle.

It is most visible on point light sources because of their small visual angle.

It covers about 2 degrees of visual angle in people.

For a given visual angle, image size depends on focal length.

What still needs to be explained, however, is why the basic visual angle illusion occurs in each example.

What matters is the visual angle which determines the size of the retinal image.

As objects become more distant they appear smaller because their visual angle decreases.

Visual angles of 5 to 37 minutes are the recommended minimum for printed information and symbols.

Particularly effective when used on bottom shelving, to hold stripping at visual angle.

At least half a degree of visual angle.

She decided to overlook the overriding visual angle of the band, and concentrate on the music.

They are outside because moving away from the computer screen has decreased the visual angle of the lilac spots.

Normally, peak contrast sensitivity is at about 4 cycles per degree of visual angle.

A constant distance between two points, subtends a smaller visual angle at a greater depth.

This finding has implications for spatial illusions such as the visual angle illusion.

Assume that the picture subtends 20 by 20 degrees of visual angle.

The visual angle is the angle between the chief rays for and .

The visual angle can be measured directly using a theodolite placed at point .

He explored it not only from a visual angle, but also from its psychological and physiological aspects.

Does global precedence really depend on visual angle?

Describing the few existing explanations for visual angle illusions is beyond the scope of this present entry.

The image is magnified, perhaps giving it a visual angle similar to the real scene the picture is depicting.

The line of sight should always bisect the observer's visual angle in order to minimize distortion.

This angle is often called the 'visual angle'.

This size difference in area V1 correlated with the 17% illusory difference between the perceived visual angles.
