Abstract: A monitoring system includes an image capturing module, a displaying module, a face recognition module, a memory module, and a searching module. The image capturing module is configured for capturing images and videos. The face recognition module is configured for recognizing a number of human faces in the captured videos, and generating a number of groups of profile information each associated with a recognized face when the image capturing module captures the video. The memory module is configured for storing the captured videos and the profile information. The searching module is configured for receiving a group of input profile information, and searching whether a group of profile information stored in the memory module matches the group of the input information. The displaying module is configured for displaying the group of captured images associated with the group of profile information matched the group of input profile information.

Abstract: An image capturing device includes a memory, a communication unit, and a processor. The memory stores a guiding system configured for guiding a user to capture an image including himself. The processor is configured for activating the system to: perform a facial recognition function on a current checking image to determine a face portion in the checking image, determine if the face portion is fully within a predetermined region of the checking image, and control the communication unit to instruct the user to adjust position of the image capturing device according to the position of the face portion in relation to the predetermined region upon the condition that the face portion is not fully within the predetermined region.

Abstract: A display system includes a display panel, a solar battery, an electric current measuring module, a memory, and a brightness adjusting module. The solar battery is for converting light energy into electric current. The electric current measuring module is for measuring electric current generated from the solar battery. The memory is for storing a pre-defined associative array of current values and their corresponding brightness values. The brightness adjusting module is for querying the associative array stored in the memory to get the corresponding brightness value, using the measured electric current value as a key, and adjusting the brightness of the display based on the brightness value returned from the associative array.
