Abstract: Techniques and examples pertaining to frame synchronization for dynamic frame rate in dual-camera applications are described. A change in brightness in ambient lighting may be detected when an electronic apparatus operates in a dual-camera mode utilizing images captured by a first image sensor and a second image sensor. In response to the detected change in brightness in the ambient lighting, frame rates of the first image sensor and the second image sensor may be synchronized.

Abstract: Signaling and feedback schemes of channel variation information from WLAN receiver are proposed. WLAN receiver performs channel tracking and obtains channel variation information. The signaling and feedback of channel variation information can help WLAN transmitter to decide when to apply travelling pilots or mid-amble in the transmission. Furthermore, the channel variation information can assist WLAN transmitter for scheduling the next transmission properly and thereby enhancing the system performance of WLAN.
