The second type concerns the detection of image displacement or a change in an image during eye movement.

This demonstrated the importance of the target object in detection of image displacements.

Sequences of ordered images allow the estimation of motion as either instantaneous image velocities or discrete image displacements.

Stability and constancy across the saccades is broken, as a result, image displacements become easier to detect when blanking occurs during or right after the saccade.

Using the device pictured on the right, Ziat et al. (2010) demonstrated a phenomenon akin to the saccadic suppression of image displacement (Bridgeman et al., 1975) in the tactile system.

Adaptation to target image displacement due to light refraction at the water-air interface consists of the bullfrog's application of tongue surface comparatively posterior to the perceived location of the prey target.

When the image region in which the homography is computed is small or the image has been acquired with a large focal length, an affine homography is a more appropriate model of image displacements.

Saccadic suppression of image displacement (SSID), is the phenomenon in visual perception where the brain selectively blocks visual processing during eye movements in such a way that large changes in object location in the visual scene during a saccade or blink are not detected.

The required sensor movement (both speed and range) increase with the focal length of the lens being used, making sensor-shift technology less suited for very long telephoto lenses, especially when using slower shutter speeds because the available motion range of the sensor quickly becomes insufficient to cope with the increasing image displacement.
