121 results about "Optical illusion" patented technology

An optical illusion (also called a visual illusion) is an illusion caused by the visual system and characterized by a visual percept that arguably appears to differ from reality. Illusions come in a wide variety; their categorization is difficult because the underlying cause is often not clear but a classification proposed by Richard Gregory is useful as an orientation. According to that, there are three main classes: physical, physiological, and cognitive illusions, and in each class there are four kinds: Ambiguities, distortions, paradoxes, and fictions. A classical example for a physical distortion would be the apparent bending of a stick half immerged in water; an example for a physiological paradox is the motion aftereffect (where despite movement, position remains unchanged). An example for a physiological fiction is an afterimage. Three typical cognitive distortions are the Ponzo, Poggendorff, and Müller-Lyer illusion. Physical illusions are caused by the physical environment, e.g. by the optical properties of water. Physiological illusions arise in the eye or the visual pathway, e.g. from the effects of excessive stimulation of a specific receptor type. Cognitive visual illusions are the result of unconscious inferences and are perhaps those most widely known.

Articles with informative patterns, and methods of making the same

A plurality of graphical elements form optical illusions associated with consumer products to aid in conveying visual perception of desired features. The optical illusions may provide perceptions of motion and / or elevation deviation into or out of a surface. Further, graphical elements sharing a single common color tone may create one or more of the illusions that may otherwise be enhanced by incorporating multiple color tones to the graphical elements creating the illusions. Exemplary consumer products include disposable diapers, feminine sanitary napkins, printed or electronic advertising media, and removable packaging enclosing articles prior to their use.

3D optical illusions from off-axis displays

A 3D viewing system captures offset images from off-axis camera perspectives inclined to a normal of base plane of a scene that includes one or more objects projecting from the base plane. The offset images, which take a planar form, are displayed from a display surface at an off-axis viewing perspective that is inclined to a normal of the display surface similar to the inclination of the off-axis camera perspective to the normal of the base plane. The offset images undergo a distortion to counteract a keystone distortion associated with the off-axis viewing perspective. The base plane of the scene is oriented parallel to the display surface, and the objects projecting from the base plane appear to project from the display surface.

Golf club head with alignment markings

A golf club putter having an alignment pattern is disclosed herein. The alignment pattern has first and second long lines that approach each other as they extend from an aft region of the putter to a front region of the putter and, when the putter is properly aligned with a golf ball, create an optical illusion of convergence of said lines at or near a center of the golf ball without actually intersecting.

Vehicle display control apparatus

A vehicle display control apparatus mounted on a vehicle includes a display control portion that controls a head-up display device displaying an image by superimposing the image on a view visible to a driver of the vehicle through a windshield of the vehicle, and a condition determination portion that determines whether a condition under which the vehicle should slow down is satisfied. The display control portion causes, based on a determination of the condition determination portion that the condition is satisfied, the head-up display device to display an object that does not actually exist on a road under circumstances where the condition is satisfied, as an illusion image that produces an optical illusion appearing that a road surface viewed from the driver flows faster than an actual speed in an opposite direction to a travel direction by superimposing the illusion image on the view.

Methods for positioning and displaying artifact or intensity inhomogeneity in digital image

The invention provides methods for rapidly positioning and displaying weak artifacts or intensity inhomogeneity in an image and detecting brightness distribution overlapping information of different targets in the image on the basis of brightness decomposition of the digital image. A decomposition image sequence and a histogram thereof are used to provide two methods for positioning display sections of the artifacts or the intensity inhomogeneity in the image. Through the sampled decomposition image sequence, the brightness range of a target of interest in the image can also be rapidly searched for and the method is simple and easy to realize. The property of the decomposition image sequence and a color mapping method are used to improve the precision of displaying the artifacts or the intensity inhomogeneity and reduce subjective deviations of visual illusion and the like. The new methods can be used for assessing the artifacts or the intensity inhomogeneity in the image and a correction method of the artifacts or the intensity inhomogeneity, or detecting the defects of an imaging object, and can also be used for retrieving brightness information of the image and positioning a brightness range of the target of interest. The decomposition image sequence histogram can also be used for rough dividing, background noise estimation or inhibition of the image or image compression.

Flying toy having gyroscopic and gliding components

Provided are flying devices and methods of manufacturing and launching same, in particular flying toys or other recreational items that are designed to be thrown through the air by a user participating in any one of a variety of throwing (i.e. “catch”) games. In particular, the concept is directed toward a flying disc having rotatably attached non-rotating (a.k.a. “gliding”) portions that are attached to the disc and provide an optical illusion, wherein the user (and, similarly, an observer) does not notice the spinning of the flying disc, but instead sees a flying craft that appears to have no propulsion, yet flies. While the non-rotating portions alter the airflow associated with a typical flying disc, they do not negatively affect the flight characteristics of the disc itself. Indeed, in certain embodiments, the non-rotating portions (e.g., ailerons) have been observed to improve the flight characteristics of typical flying discs. The non-rotating portions (a.k.a. “gliding”) also provide surfaces upon which to place advertising that remains legible during flight. In this manner, the non-rotating portions of the flying device serve both a functional and an aesthetic purpose

Coloring picture, coloring picture generating apparatus, and coloring picture generating method

A watercolor effect-added coloring picture 10 includes original image color areas 16 formed along linework areas 12 to be extended in a predetermined range from the linework areas 12 and filled with specified colors based on the colors of an original image, and blank areas 14 formed adjacent to the original image color areas 16. The linework areas 12 are filled with an achromatic gray color having a high luminance value, while the original image color areas 16 are filled with chromatic colors and are formed to have higher luminance values than the luminance value of the linework areas 12. This arrangement gives the watercolor effect as one illusion effect that creates the optical illusion of spread of a paler color over a neighboring area adjacent to a paler color line of two-color double lines. Although the blank areas 14 are actually not filled with any colors, the watercolor effect gives the illusion of the spread of the specified colors of the original image color areas 16 over the whole blank areas 14. The original image color areas 16 are formed in a width as narrow in width as the linework areas 12 and thus do not significantly disturb the user s coloring of the coloring picture 10 even with different colors from those of the original image.
