Likewise for object point and its retinal image at .

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

Insects, like mammals, extract the orientation of edges within the retinal image.

It is the class of retinal images which make the perceptron fire.

Of the remaining two, one should be on if there is a dog on the retinal image.

Such visual characteristics are likely to produce a well-focused retinal image of objects in both the middle and long distance.

Information in the retinal image may be interpreted in many different ways.

These mechanisms are only able to function due to the large sized retinal image.

The vestibular system monitors the position and movements of the head to stabilize retinal images.

In a textured surrounding, however, the induced moving retinal image is ignored.
