Dynamic Image Correction for Lens Flickering

The patent dynamically adjusts the correction value based on the rate of change of lens unit state. When the lens state changes rapidly, the correction value is updated more conservatively to prevent flickering. When changes are gradual, full real-time correction is applied. This dynamic adjustment strategy resolves the contradiction by adapting the correction behavior to the actual state change conditions.

The patent introduces an intermediate mechanism that compares the current lens state with previous states and determines the appropriate correction strategy based on the change rate. This intermediary processing layer acts as a buffer between the raw lens state information and the final correction application, preventing direct transmission of rapid changes that cause flickering while still maintaining effective correction for gradual changes.

The patent implements dynamic time constant adjustment where the time constant is varied based on the rate of lens state change. When the lens state changes rapidly, a smaller time constant is used to allow faster correction response. When changes are gradual, a larger time constant is applied to smooth out fluctuations and prevent flickering. This dynamic parameter adjustment resolves the contradiction between response speed and stability.

The patent changes the time constant parameter adaptively based on the observed lens state change rate. By modifying this critical parameter in response to operating conditions, the system achieves both fast response when needed and smooth correction when possible, resolving the trade-off between correction speed and flickering prevention.

The patent applies dynamic interpolation that adapts to the sampling interval and data resolution. When sampling intervals are large or resolution is low, the interpolation algorithm uses historical data and change rate information to generate smoother correction values, effectively continuousizing the discrete corrections. This dynamic approach maintains good moving image quality despite simplified communication requirements.

The patent creates interpolated copies of correction values between sampled points. Rather than directly using the discrete sampled values, it generates intermediate copy values through interpolation, effectively increasing the resolution and continuity of correction data without requiring higher-resolution original measurements or more frequent sampling.

The patent implements dynamic damping that adjusts the steepness of correction value changes based on the lens state change rate and image type. For still images, steeper changes are permitted for faster response. For moving images, the damping is increased to smooth transitions and prevent flickering. This dynamic adjustment resolves the contradiction between responsiveness and naturalness by adapting to the specific operational context.

The patent uses feedback from the lens state change rate and image type to modulate the correction value changes. The system continuously monitors the situation and adjusts the correction application accordingly, reducing change steepness when flickering is detected or likely, and allowing steeper changes when conditions permit. This feedback mechanism resolves the contradiction by making correction behavior context-aware.
