| 説明 | This print advertisement formed part of Sony's successful Bravia campaign in the UK and Argentina. This is the one of the four print ads in the series.The type of optical illusion used in the ad is called a scintillating grid illusion, a sub-type of physiological illusion.These are caused by the effects on the eyes and brain from excessive stimulation of a specific type - brightness, tilt, color, movement.It is believed the stimuli have in the early stages of visual processing, individual dedicated neural paths. When only one or a few channels have continual stimulation, a physiological imbalance develops that alters perception.Source: Wikipedia Optical IllusionThe grid “is constructed by superimposing white discs on the intersections of orthogonal gray bars on a black background. Dark dots seem to appear and disappear rapidly at random intersections, hence the label “scintillating”. When a person keeps his or her eyes directly on a single intersection, the dark dot does not appear. The dark dots disappear if one is too close or too far from the image.“Observations suggest that a minimum of 3 x 3 evenly spaced intersections with superimposed discs are required to produce the effect. This requirement suggests the participation of global processes of the kind proposed for the linking and grouping of features in an image, in addition to local processes.”Source: Wikipedia Optical Illusion - Grid Illusion[Reciprocal link back Optical Illusions] |
