AI Technical Summary

Technical Problem

Existing zoom camera control methods have insufficient fill light performance at long distances, making it difficult to achieve automatic focusing and motion tracking. In addition, the infrared controller has low control accuracy during single-channel signal transmission and cannot meet the fill light requirements at long and short distances under small and large focal lengths.

Method used

By obtaining the expected gain value of the camera and comparing it with the intensity adjustment threshold, the intensity adjustment of the infrared light is controlled, including increasing the intensity at a low intensity threshold, reducing the intensity at a high intensity threshold, and keeping it unchanged between the thresholds, thereby achieving infrared light intensity control at different angles at different focal lengths.

Benefits of technology

It achieves a multi-objective balance among exposure accuracy, image quality protection, and power consumption optimization, improving the robustness and user experience of zoom cameras under complex lighting conditions, ensuring fast and accurate focusing and tracking of target objects, and adapting to fill light requirements at different focal lengths.

Abstract

The embodiment of the invention discloses a zoom camera infrared control method and device, electronic equipment and a computer readable storage medium, and relates to the technical field of cameras, and the method comprises the steps: obtaining a current expected gain value of a camera; comparing the expected gain value with the intensity adjustment threshold value to obtain a comparison result; when the comparison result is that the expected gain value is greater than or equal to the low-intensity threshold value, controlling the infrared lamp to improve the intensity; when the comparison result is that the expected gain value is smaller than or equal to the high-intensity threshold value, controlling an infrared lamp to reduce the intensity; and when the comparison result is that the expected gain value is less than the low-intensity threshold value and greater than the high-intensity threshold value, controlling the intensity of the infrared lamp to be unchanged. Therefore, multi-target balance of exposure accuracy, image quality protection and power consumption optimization is achieved, the method is suitable for scenes which are complex in illumination condition and need long-time stable operation, and the robustness and user experience of equipment in a non-ideal environment are effectively improved.
