Imaging artifact precompensation for spatially multiplexed 3-D displays

2015

SPIE Proceedings

Increasing the resolution of the LCD (or similar) display used in projectors (in conjunction with increased light emissions, etc.) increases the resolution of the projected image and/or the distance that the projector can be from its screen. While increasing the size of the LCD panel represents one approach to producing increased resolution, this increases projector size and weight. This paper proposes the introduction of a mechanism to allow multiple pixels to be combined to create a higher resolution output image than the LCD (or similar) display used to create virtual pixels, increasing the effective resolution of the projector.

A virtual pixel software and hardware technology to increase projector resolution

2015

SPIE Proceedings

“…Prior display enhancement work has included the display of sub-frames at a higher rate than the source video [17,18] and a technique for still imagery [19] which also uses sub-frames. A variety of work has been performed both in the fixed overlay and movement based categories.…”

A virtual pixel technology to enhance the resolution of monitors and for other purposes

Display Technologies and Applications for Defense, Security, and Avionics IX; And Head- And Helmet-Mounted Displays XX

2015

Current monitor and television displays utilize pixels to display an approximation of the real world collected by a camera or generated computationally. This paper proposes a virtual pixel technology which incorporates coloring LCD combination. Each physical pixel's configuration is based on a weighted average of the virtual pixels it contributes to. This allows lower pixel density displays to produce the approximation of a higher pixel density, while lowering production cost. The paper provides an overview of the proposed technology, discusses its application to monitors and extension to other areas and concludes with a discussion of the next steps to its development.

“…The use of computed sub-frames that are displayed at higher-than-source rates [20,21], as well as techniques for still images, using sub-frames [22], have also previously been demonstrated. Prior work on overlaid coloration sources has included the use of optical pixel sharing [23], display super-sampling [24], and superimposition techniques for projectors [25] and conventional displays [26].…”

Enhancing head and helmet-mounted displays using a virtual pixel technology

2015

SPIE Proceedings

Head and helmet-mounted displays utilize pixels to display a digitized approximation of the real world. These displays must have a higher pixel density (as compared to a monitor or projected image) to create the same level of perceived resolution. This paper proposes a virtual pixel technology which incorporates a virtual pixel creation function. Each physical pixel's configuration is based on the virtual pixels that it contributes to, allowing lower pixel density display hardware to produce the approximation of a higher pixel density. The paper provides an overview of the proposed technology and how it is applicable to head/helmet-mounted displays and considerations related thereto.
