However, power consumption (2.1 W at 120 fps) is 30% higher than the IMX490, limiting use in battery‑operated devices. Thermal management above 60 °C increases dark current by 2.1×, requiring active cooling for long-term medical use. The Canon K10514 demonstrates state-of-the-art low-light performance and rolling shutter suppression, making it a strong candidate for medical endoscopy and night surveillance. Future work will integrate the sensor with on-chip AI denoising and test it in a sterilizable endoscopic housing. 7. References [1] Canon Inc. (2024). Internal sensor roadmap: K-series prototypes .
