Wearable Display Brightness Adjustment via Image Verification

The patent introduces an image capturing circuit as an intermediary to verify the reliability of light sensor data. The circuit captures images of the light source, and object detection algorithms analyze whether the light path is blocked. This intermediary verification mechanism resolves the contradiction by providing a cross-check on the light sensor measurements without fundamentally changing the brightness adaptation function.

The system implements feedback by continuously monitoring the environment through image capture and comparing it with light sensor readings. When the image analysis indicates blockage (e.g., dark regions obscuring the light source), the system adjusts its interpretation of light sensor data accordingly. This feedback loop prevents incorrect brightness adjustment while maintaining adaptive display functionality.

The image capturing circuit serves multiple functions: it verifies light sensor data accuracy, detects environmental context, and provides backup brightness estimation when light sensors are blocked. This multi-functionality justifies the added complexity by providing robust brightness control across various scenarios without requiring separate dedicated components for each function.

The patent merges the light sensing function with image capture functionality. The same image capturing circuit used for general AR display purposes is also utilized to verify light source visibility and validate light sensor readings. This merging approach minimizes additional hardware complexity while achieving more accurate display brightness adjustment through combined data analysis.
