Imaging device, and image processing method and program for imaging device

This invention describes an imaging device that captures images using a sensor sensitive to both visible light and near-infrared light. To make these images clearer, the device processes them using a special filter. This filter is uniquely calculated by combining the optical properties of the camera's lens for both visible and near-infrared light, allowing a single filter to improve image quality across both spectrums. The device may also include a near-infrared light source and a retractable infrared cut filter.

Why it matters: Filed before widespread adoption of AI for image processing. Modern neural networks could now learn and apply the restoration filter more effectively and efficiently on current hardware.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSoftware logic, NIR emitter, retractable IR filter
