Camera device capable of automatically adjusting detection distance and control method thereof

Abstract

The invention discloses a camera device capable of automatically adjusting a detection distance and a control method thereof. The camera device comprises an LED light filling module, a light detection module, an infrared detection module, a signal processing module, a DSP control module and a camera module. The light detection module, the LED light filling module, the camera module and the signal processing module are all electrically connected with the DSP control module, and the infrared detection module is electrically connected with the signal processing module. The light detection module detects the light intensity parameter in a real-time camera shooting environment and transmits the light intensity parameter to the signal processing module through the DSP control module. The signal processing module adjusts the processing parameter to an infrared detection distance according to a received control parameter and feeds the infrared detection distance parameter back to the DSP control module. The DSP control module controls the camera module to take images according to the received infrared detection distance parameter. The camera device capable of automatically adjusting the detection distance and the control method thereof can be used for adjusting the image taking distance of the camera module and are beneficial to improving the camera shooting quality of the camera device.

Description

technical field [0001] The invention relates to monitoring camera equipment, in particular to a camera device capable of automatically adjusting a detection distance and a control method thereof. Background technique [0002] In the existing security monitoring camera field, there are two common monitoring camera modes: a 24-hour uninterrupted camera mode and an intermittent infrared monitor camera mode. The hunting camera belongs to the intermittent infrared monitoring camera mode. Its working principle is to start the camera unit to take pictures after the infrared detection unit captures people or animals, and the camera unit is turned off during the rest of the time. The advantage of using the intermittent infrared surveillance camera mode is that this type of surveillance camera is used in places with a small number of people or animal activities, which can effectively save energy and energy for long-term use, and reduce a large amount of invalid video data to facilitat...
