| 发明名称 | Reducing angular spread in digital image projection | ||
| 摘要 | Chromatic aberration can be reduced and extreme projection angles can be allowed in a projection system by modifying one color channel of light having a wavelength bandwidth with image data to produce imaged light, causing the imaged light to spread angularly when displaying the imaged light through an optical distorting element onto a screen, and reducing angular spread of the imaged light exiting the optical distorting element by adjusting the wavelength bandwidth. | ||

| 主权项 | 1. A method of digital projection, comprising: modifying one color channel of light having a wavelength bandwidth with image data to produce imaged light; causing the imaged light to spread angularly when displaying the imaged light through an optical distorting element onto a screen, wherein the optical distorting element causes an angular color separation of the imaged light; and reducing angular spread of the imaged light exiting the optical distorting element by adjusting the wavelength bandwidth that reduces the angular color separation of the imaged light appearing on the screen. | ||
