AI Technical Summary

Technical Problem

Existing camera systems face issues with power consumption exceeding the maximum supply of Power over Ethernet (POE) when multiple imaging units use infrared illumination simultaneously, leading to insufficient infrared illumination and unclear images in low-light environments.

Method used

An imaging control device that distributes power to multiple imaging devices based on priority settings, controlling the output of their illumination units to maintain clear imaging within power constraints by reallocating surplus power and adjusting illumination intensity and frame rates.

Benefits of technology

Enables clear image capture in low-light conditions by optimizing power distribution and illumination usage across multiple devices, ensuring compliance with POE limits while maintaining image quality.

Abstract

To provide an imaging controller that captures a clear image even when power supply is limited due to a low illumination environment.SOLUTION: An imaging controller controls a plurality of imaging devices each including an irradiation unit that emits infrared light. The controller sets power to be distributed to each of the plurality of imaging devices, according to a priority that is set for each of the plurality of imaging devices. The controller controls the output of the irradiation unit that is included in each of the plurality of imaging devices, according to the set power.SELECTED DRAWING: Figure 1
