Transient Contrast
When the image content is changing rapidly, e.g. during the display of video or movie content, the optical state of the display may not reach the intended stable steady state because of slow response and thus the apparent contrast is reduced if compared to the static contrast.
| This illustration shows the repetitive impulse response between several states of gray when each state is applied for one frame only. It is obvious that the stationary luminance levels (indicated by dashed horizontal lines) are not reached within a single frame. |

Famous quotes containing the words transient and/or contrast:
“For the most part we allow only outlying and transient circumstances to make our occasions. They are, in fact, the cause of our distraction.”
—Henry David Thoreau (1817–1862)
“Flowers and fruits are always fit presents; flowers, because they are a proud assertion that a ray of beauty outvalues all of the utilities of the world. These gay natures contrast with the somewhat stern countenance of ordinary nature: they are like music heard out of a work-house.”
—Ralph Waldo Emerson (1803–1882)
