1. A driving method for a height-adjustable biological signal measuring device, the method comprising:
a step of recognizing a user's unique information;
a step of setting a focus of a video image measuring device to a preset value when a user recognition is completed;
a step of photographing the user and acquiring the user's images from the video image measuring device when the focus of the video image measuring device is set;
a step of acquiring image data from the photographed video image and preprocessing the image in a video image processing unit;
a step of recognizing a face according to the user's state using a pre-processed image when the image is pre-processed;
a step of determining whether the user's face is at a center of a screen after processing the user's state and face recognition; and
a step of fixing a position of a terminal and measuring the user's biometric information when the user's face is determined to be at the center of the screen,
wherein the user's bio-signals are measured by irradiating the user's face with near-infrared rays from an optical output unit of the terminal and by analyzing the irradiating near-infrared rays with the video image measuring device,
wherein the step of recognizing the user's state and face comprises: recognizing the user's state and face by comparing data of RGB values and HSV values of the acquired image with a data table including RGB values and HSV values of a plurality of reference images in which the user's face is considered as positioning at the center of the screen stored in a central server.
