Focusing Aids TRIZ Cases

Time-series AF prediction switches lens drive modes to balance focus accuracy and response speed during continuous imaging.

Variable damping changes with rotation angle through axial pressure-member movement, giving lens control users adjustable tactile feedback.

Displacement-based in-field recalibration updates actuator drive data to restore autofocus precision and optical image stabilization.

Weighted high-contribution autofocus regions improve focus on misaligned target portions while preserving calculation robustness.

Replacing ball bearings with shaft rails and a rail guide cuts denting and wear while improving optical actuator precision and durability.

Different-sized shared micro lenses let adjacent color pixels support PDAF while preserving image quality and sensitivity in normal and binning modes.

Different on-screen indexes show which pupils fall inside or outside a target depth, helping users set focus so both eyes stay sharp.

A five-unit lens layout moves only the second and fourth groups to speed autofocus while keeping aberration shifts controlled across the focus range.

Fixed-focus mobile cameras struggle across shooting distances; a variable-curvature autofocus component supports compact, stable imaging.

Lens movements can change sensor light intake during live-view flicker detection; controlled drive adjustment stabilizes exposure and accuracy.

This case uses in-focus detection and stored settings to restore the intended target when manual focus returns to autofocus.

This five-lens-unit optical system moves the second and fourth units to reduce focus weight and preserve image quality across focusing.

A focus control method standardizes sharpness variation across multiple optical systems for seamless switching.

Replacing coils and magnets with a shape memory alloy wire simplifies the mechanical structure while maintaining precise focusing capability.

A focus control apparatus dynamically selects between autofocus and manual focus modes based on subject movement and user operation signals.

Flicker current detection circuitry isolates pixels to analyze signal patterns, eliminating auxiliary sensors and reducing power consumption.

An imaging apparatus sets an autofocus target region by detecting overlap between a subject detection frame and a related region.

Processor normalizes defocus amounts across image heights using height-based ratios, resolving comparison errors for accurate autofocus control.

A vibration apparatus adjusts amplitude, frequency, and time to provide tactile feedback during image capture operations.

A terminal device uses an infrared cut-off coating to filter near-infrared laser beams, eliminating red spots in photographs.

An electronic apparatus adjusts focus frames to improve object visibility during capture.
