- 詳細技術說明
- This invention is software and hardware that enhances the resolution of a projector. It uses light modulator panels to create higher resolution at selected regions of a display. This is enabled by special hardware called an optical pixel sharing unit, which can create a higher density of pixels at selected regions. This allows for higher resolution at desired locations like edges, faces or the boundary of foreground and background. The key to producing the aforementioned variable resolution is to enhance the resolution of the display at a few important pixels using this optical pixel sharing hardware. The technology exploits the sparsity of the important pixels to achieve a higher pixel density at a few locations. The end result is a display that is perceptually similar to a true high resolution display at a lower cost. This process opens up the possibility of targeting resolution at application-specific spatial regions of the display, like faces for surveillance. The researchers have also developed GPU based computation techniques that allow for real-time content specific imaging processing to select the important pixels that are to be rendered in higher density. Using a lower resolution projector to display a higher resolution image will render the image blurry and pixelated. As would be expected, in order to properly display a higher resolution image, a higher resolution projector is required. Unfortunately, the cost of projectors rise exponentially with increasing resolution and therefore, upgrading to a higher resolution display is not always feasible. Creating smaller pixels and therefore, higher resolution using lower resolution display modules has been a goal of the display community for many years. This technology solves that problem by creating a display that is perceptually similar to higher resolution displays while using lower resolution projectors.
