Photoelectric Conversion Apparatus Input Node Voltage Control

The patent applies dynamics by making the signal line voltage time-dependent and adaptive. The voltage is dynamically adjusted based on which pixel type is currently outputting signals: set to a first voltage level when first pixels output first signals, and a second voltage level when second pixels output second signals. This dynamic voltage adjustment ensures that the processing unit always operates at the appropriate voltage level for the current signal type, resolving the contradiction between maintaining signal accuracy and ensuring voltage consistency.

The patent changes the voltage parameter of the signal line based on the operating mode. A control unit monitors whether first pixels or second pixels are currently active and adjusts the signal line voltage accordingly. When first pixels are active, the voltage is set to a first level; when second pixels are active, it is set to a second level. This parameter change approach allows the system to maintain optimal signal accuracy for different pixel types while ensuring voltage consistency within each operating mode.

The patent applies preliminary action by pre-setting the signal line voltage to the appropriate level before each pixel type outputs its signal. The control unit anticipates the signal output and adjusts the voltage in advance, ensuring that the processing unit is ready to receive and process the signal at the correct voltage level without waiting for voltage transitions during signal output. This eliminates timing conflicts and ensures smooth voltage transitions.

The patent implements feedback through the control unit that monitors the output state of different pixel types and adjusts the signal line voltage accordingly. The control unit receives feedback about which pixels are currently outputting signals and dynamically adjusts the voltage level to match the required signal type, ensuring continuous optimal operation without timing errors.
