  • Patent number: 11087473
    Abstract: A method for detecting motion information includes the following steps. First, a pixel array is provided for detecting an image of a measured object located in a first distance range or in a second distance range, and the pixel array includes a plurality of invisible image sensing pixels and a plurality of visible image sensing pixels. Then, image detection is conducted within the first distance range by using the invisible image sensing pixels to output a plurality of invisible images. Next, the image detection is conducted within the second distance range by using the visible image sensing pixels to output a plurality of visible images. Then, the plurality of invisible images and the plurality of visible images are analyzed by using a processing unit, so as to obtain motion information of the measured object. A pixel array for detecting motion information and an image sensor are also provided.

  • Publication number: 20210027590
    Abstract: A smart motion detection device includes an image sensor, an infrared sensor and a processor. The image sensor captures a monitoring image. The infrared sensor detects a thermal motion condition and provides an alarm signal accordingly. The processor executes an image recording mode of the image sensor only according to the alarm signal when an image quality of the monitoring image is unacceptable.

  • Publication number: 20200284575
    Abstract: There is provided an imaging system including a camera and a control host. The camera identifies ambient light intensity and performs trigger event detection in a low power mode. When the camera detects a trigger event in the low power mode, the control host is woken up. The camera also determines an exposure mode according the ambient light intensity and informs the exposure mode to the control host such that an operating mode of the control host after being woken up matches the exposure mode of the camera.
