AI Technical Summary

Technical Problem

Existing imaging devices struggle to achieve a wide dynamic range while maintaining signal-to-noise ratio and efficiency in low illuminance conditions.

Method used

The implementation of a charge accumulation capacitor with a variable capacitance value, controlled by a specific circuit, which adjusts in response to the potential of the charge accumulation portion, combined with a MOSFET-based transistor configuration, allows for a single readout mode that enhances dynamic range and signal quality.

Benefits of technology

This configuration enables a wide dynamic range with improved signal-to-noise ratio and reduced power consumption, particularly in low illuminance conditions, without the need for image synthesis.
