Title:
A method, a system, and a kit which project a picture using a digital projector
Document Type and Number:
Japanese Patent JP6186635
Kind Code:
B2
Abstract:
Generating a high definition projected illumination pattern from a substantially lower resolution digital projector array involves: selectively illuminating a connected set of pixels to produce a pixellated, high contrast edge feature, and positioning an anisotropically blurring optical element (ABOE) between a light source of the projector array and the projection. The ABOE applies an anisotropic blur pattern to pixels of the at least one connected set, to locally preferentially blur the pixel more (and preferably substantially only) in a direction of equally or more strongly illuminated pixels, and not in directions of less illuminated pixels. Preferably a contour of the connected set has no beginning or end within a periphery of the illumination plane, and has bounded curvature, permitting simple ABOEs to be used. Several images each having several or many edges can be produced using a same ABOE. The ABOE may alleviate interpixel gap effects for non-edge pixels too.
