Now low-cost computation coupled with camera-driven feedback can compensate for the misalignments, optical imperfections, and fabrication shortcuts found in many commercial optical products today. EasyBlend uses camera feedback of an image array to eliminate digital image warping, correct color, and blend images. This entirely digital, scalable technology produces displays that are bright, high resolution, portable, and self-calibrating. Using SDT’s technology, project a single seamless wall of overlapping images. Our purely digital approach allows you to create displays that simply can’t be engineered by conventional mechanical or optical means.

Camera feedback and digital image processing using SDT’s EasyBlend software produces the highest-quality image for the lowest price. Replace costly labor-based precision and optical skill with inexpensive digital image processing. SDT algorithms will automatically:

• Provide soft edge blending for seamless tiling of images from multiple projectors, even when positioned at odd angles
• Correct for special optical distortion
• Adjust for image warping on flat, cylindrical, spherical, and arbitrary surfaces
• Ensure uniformity by matching intensity and color across an image generated from multiple projectors
• Correct color across an image
• Scale content to fit screen size
• Detect screen frame automatically or via manual specifications
• Compensate for projector-lamp brightness and color degradation, ensuring color temperature and uniformity are maintained over time
• Work with available external warping hardware
