When the single or multiple users move the position, the distance between the user and the electronic device and the angle or elevation angle maintained by the center of the electronic device 1 may change, so that the corresponding user position changes accordingly. When the processor determines that the position of the user is changed by comparing the user position obtained by the description with the position of the user corresponding to the original electronic device, the parameter adjustment according to the user position of the change 4 is performed by the processor. Conversely, when the user's location has not changed, return to the original step (4) to obtain a new live image for analysis or for other status information. 201109873 Step S32: Determine whether the number of users has changed. The processor 31 determines whether the number of users changes according to the number of users corresponding to the current number of users and the state of the original electronic device 1. When the number of users changes, it represents between users in the instant image. The relative position has changed, that is, the corresponding user position has been changed, so the corresponding parameter adjustment will be made according to the changed user position; and when the number of users has not changed, the original step S1 is returned to obtain a new instant. Images are analyzed or judged against other status information. Step S33: Determine whether the status information related to the background changes. The status information related to the background obtained by the processor 31 for the foregoing step S22 is compared with the status information related to the background corresponding to the original electronic device 1 to determine whether the status information has changed. For example, if the user increases or decreases the background brightness of the environment in which the electronic device 1 is located by using a lighting device or a curtain, or changes the background color using a light source of a different color, the status information is changed, and thus the status information according to the change is performed. Corresponding parameter adjustment of the electronic device 1; when the status information has not changed, then φ is returned to the original step S1 to obtain a new live image for analysis or for other status information. Step S4: When the status information is changed, the electronic device 1 is controlled according to the status information. As shown in FIG. 1, when the status information is changed by the foregoing steps, the processor 31 determines the corresponding adjustment parameter according to the different status information, so as to facilitate the corresponding control of the electronic device 1. The processor 31 performs corresponding adjustments for the main body of the electronic device 1 and the output image by the notification driving module 32 and the parameter adjustment module 33. For example, when the angle between the user and the electronic device 1 is changed, the processor 31 can notify the driving module 201109873 32' to adjust the substantially horizontal angle of the electronic device body. When the user changes the elevation angle of the electronic device 1, The driving module 32 is also notified to adjust the substantially vertical angle of the electronic device body; wherein the driving module 32 can be at least one motor device, but the invention is not P. For example, when the background brightness is changed, the processor 31 can notify the parameter adjustment module 3 3 to adjust the brightness or color of the image for the wheeled image, so that the user has a better visual effect.
