Exposure Prediction In Video Capturing, Jinglun Gao, Szepo Robert Hung, Ruben Velarde, Gang Sun

Defensive Publications Series

This publication describes methods, techniques, and apparatuses that enable a handheld electronic device, such as a smartphone, to capture high-quality static images (photographs) and accurately determine an exposure configuration when capturing videos (multiple frames per second (FPS)). To do so, the smartphone utilizes an auto-exposure (AE) algorithm. The AE algorithm combines data from motion sensors (e.g., gyroscopes and accelerometers) and optical flow data from image sensors (e.g., complementary metal-oxide-semiconductor (CMOS) image sensor). The AE algorithm increases video quality without using additional computational power, more battery life, nor more volatile and non-volatile memory.

Quick And Convenient Establishment Of Wireless Communication, Feng-Jui Kuo

Defensive Publications Series

Communication between paired Bluetooth devices is not always immediate. This is because there are often several devices in the vicinity that are paired with a user’s device, and the user may need to go through a process of selecting one of the paired devices to route communications. This device selection procedure can be further complicated by the sometimes cryptic names assigned to the devices. Per the techniques of this disclosure, images of a Bluetooth accessory are captured at the time of pairing with a Bluetooth device. The user points a camera to the Bluetooth accessory to establish a communication path.
