Abstract: A car lens offset detection method and a car lens offset detection system are provided. The first image capturing device and the second image capturing device are disposed on a car, and the method includes: capturing a first image with use of a first image capturing device and capturing a second image with use of a second image capturing device; obtaining a plurality of first feature points from the first image according to a plurality of first predetermined positions and obtaining a plurality of second feature points from the second image according to a plurality of second predetermined positions; comparing feature values of the first feature points with feature values of the second feature points and determining whether the first feature points match the second feature points; in response to the first feature points not matching the second feature points, performing a calibration and warning operation.

Abstract: A collaborative transmission method and a transmission device based on UDP (User Datagram Protocol) and TCP (Transmission Control Protocol) connections are provided. The collaborative transmission method comprises: calculating a first rate and obtaining a first parameter, wherein the first rate is a rate using TCP to transmit packets and the first parameter is associated with the variation degree of the first rate; after obtaining the first rate, calculating a number of packets to be sent according to a target bit rate, the first parameter, the first rate, and a packet size, wherein the number of packets to be sent is the number of packets expected to be transmitted via UDP; and determining to use either UDP or TCP to send the packet according to a transmission flag and updating the number of packets to be sent when the packet number is not zero.

Abstract: An energy consumption alarm method and a display thereof are disclosed. The method is applied for determining whether the energy consumption of a display complies with an energy consumption regulation or not. The energy consumption alarm method includes the following steps: generating a backlight value; detecting an output volume; determining whether the backlight value is greater than a backlight threshold according to the energy consumption regulation and the output volume; and if the backlight value is greater than the backlight threshold, the displaying a alarm signal.
