Abstract: There is provided a photographing device having two output interfaces that respectively used to output a first image frame and a second image frame. The first image frame is provided to a processor of the photographing device to perform the feature extraction and tag the second image frame accordingly. The tagged second image frame is for the image recording of an external back end.

Abstract: A motion detection method utilized for a motion sensor includes: capturing a monitoring image; entering a recording mode when one intensity change value between the monitoring image and a pre-stored background image is higher than a first threshold and a trigger signal is received from an auxiliary sensor; and entering the recording mode when the intensity change value is higher than a second threshold before the trigger signal is received; wherein the second threshold is higher than the first threshold.

Abstract: An image sensing method, comprising: (a) controlling an image sensor to apply a first frame rate to sense a first frame during a first frame period; (b) determining exposure variation in the first frame period; and (c) during one of the first frame period and a second frame period following the first frame period, switching the image sensor to apply a second frame rate different from the first frame rate to sense at least one third frame, when the step (b) determines the exposure variation exceeds a threshold level. A related image sensing system is also disclosed. Via such image sensing method, the frame switch delay of a conventional frame switch can be reduced.
