Picture Reproducers Using Projection Devices TRIZ Cases

Alternating MEMS mirror scan directions and start positions reduces moire patterns and dark areas in projected images.

Depth mapping starts before motion fully stops, enabling faster projector orientation detection and accurate keystone correction.

A laser scanning eye implant projects camera images onto the retina, avoiding microdisplay polarizer losses and easing implant placement.

Depth sensing and area-weighted interpolation map curved projection planes to correct image distortion and preserve display quality.

A photodetector tracks actual mirror position so the controller can correct temperature-driven sensor delay and keep projected pixels aligned.

Depth-sensor-based correction adjusts pixel brightness and distortion to keep projected images uniform on non-planar surfaces.

A single molded lens array replaces multiple diffusers to uniformize laser light, remove speckles, and shrink projection light engines.

Sensor-based surface modeling adjusts pixel projection points to correct distortion on curved projection planes and preserve viewer-aligned image quality.

Time-divided phase-only subframes replace light attenuation and extra modulators to improve HDR projection efficiency and contrast.

Virtual setup calculates alignment, ID, and IP parameters before power-on, cutting manual multi-projector installation time and labor.

Electro-optic liquid crystal gratings replace slow thermal IR arrays to deliver faster, broadband scene projection with fine resolution.

Rotating the on-screen capture view to match a projector image helps portable devices frame the full projection surface and correct distortion.

Precomputed viewpoint-to-image mapping replaces camera correction to improve projection accuracy and efficiency in vehicle simulators.

Virtual projection and camera simulation use feature points to auto-calibrate distortion and layout, speeding immersive system setup.

Actuator deflection compensates color-dependent refraction shifts in projection optics, reducing lateral color and halo for cleaner images.

Virtual-viewpoint image mapping replaces multi-camera correction to improve projection alignment accuracy in vehicle simulators.

Blending virtual and native color gamuts expands 2D color range in 6P projection while reducing chromaticity errors and improving dynamic range.

Camera preview prompts detect screen boundary overflow, then a shot image guides projector correction to keep the image aligned within the screen.

A refractive element expands and redirects homogenized color light onto the micromirror array, shrinking projector optics without sacrificing image quality.

Static detectors and calculated feature placement enable accurate conjugate contrast measurement in holographic replay fields despite misalignment.

A built-in or external camera captures a test image in a preset region to speed accurate projection correction on uneven reflecting surfaces.

Sub-area distance selection filters obstacle interference during autofocus, keeping projected images sharp and within the intended area.

Distance ratios from a ToF sensor replace heavy image analysis, enabling fast projector keystone correction with lower computing cost.

A management-authority terminal screens new monitor connection requests so ongoing presentations continue without display interruption.

A dual-state LC panel shifts high-resolution imagery with gaze direction, keeping foveal detail sharp without full-field high pixel density.

Combining depth and reflected-light intensity helps a projector model inclined or uneven surfaces for more accurate image correction.

Maps a largest in-quadrangle rectangle from panel vertices and diagonal intersection to preserve image area after distortion correction.

Combining depth sensing with projector gravity data improves projection surface correction when distance measurements alone limit accuracy.

Switching between optical projectors keeps 3D pattern projection stable despite heat, assembly variation, and fixed-pattern detection errors.
