Solid-State Imaging Device Variable Charge Transfer Gain Control

The patent applies dynamics by making the number of charge transfer operations variable rather than fixed. The transfer control unit dynamically adjusts the number of transfers based on capturing conditions, allowing the system to optimize between saturation charge amount and image quality in real-time. This resolves the contradiction by enabling adaptive operation where multiple transfers can be used when high charge amount is needed, while single transfers preserve image quality when conditions permit.

The patent changes the parameter of transfer operation count from a fixed value to a variable parameter controlled by capturing conditions. By adjusting this parameter dynamically, the system can achieve high saturation charge amount when multiple transfers are performed, while maintaining image quality when fewer transfers are used. The amplifier gain is also adjusted as a corresponding parameter to maintain signal quality.

The system dynamically adjusts the number of charge transfer operations based on actual capturing conditions rather than performing fixed multiple transfers. This allows the system to achieve necessary saturation charge amount while minimizing the number of transfers, thereby reducing noise generation and power consumption associated with repeated transfer operations.

Instead of always performing multiple charge transfers, the system applies partial action by using only the necessary number of transfers required to achieve adequate saturation charge amount. This avoids excessive transfer operations that would generate unnecessary noise and consume additional power, while still achieving the required charge accumulation.
