Photographing Module With Switchable Bayer Filtering for Higher Resolution

The patent applies the dynamics principle by making the filtering array layer movable instead of fixed. The filtering array layer can be driven to different positions (first position, second position, third position) relative to the pixel regions, enabling dynamic switching of filtering configurations. This dynamic adjustment allows the system to optimize between resolution and photosensitivity by selecting appropriate filtering patterns for different imaging scenarios.

The patent introduces a temporal dimension to the imaging process by capturing multiple images at different filtering array positions and synthesizing them. Instead of relying solely on spatial pixel density, the system uses time-multiplexed filtering patterns (first filtering pattern, second filtering pattern, third filtering pattern) to effectively increase the information captured per scene, thereby improving definition without permanently increasing pixel count.

The patent creates multiple copies of the same scene captured through different filtering patterns. By capturing the same scene multiple times with the filtering array layer in different positions, the system obtains redundant information that can be used for reliable synthesis. This is more reliable than interpolation because it uses actual captured data rather than computationally estimated values.

The patent merges multiple images captured with different filtering patterns into a single high-definition image. The image synthesis process combines the information from images taken at different filtering array positions, effectively merging the data to produce a result that exceeds the resolution of any single captured image, while avoiding interpolation errors.

The patent segments the filtering array layer into multiple independent filtering sub-layers (first filtering sub-layer, second filtering sub-layer, third filtering sub-layer), each corresponding to different pixel regions. This segmentation allows for controlled movement between discrete positions, making the multi-frame synthesis process more manageable. Each position captures a specific filtering pattern, and the synthesis algorithm can selectively combine these segmented views.

The patent uses dynamic control of the filtering array layer position to simplify the synthesis process. By automatically driving the filtering array layer to predetermined positions (first position, second position, third position) and synchronizing with the imaging capture, the system reduces manual control complexity. The dynamic positioning ensures that each frame is captured at the optimal filtering configuration, making the overall process easier to control while maintaining high image quality.
