摘要： 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.

摘要： An event detection device includes a sensor array and a processor. The sensor array is adapted to capture one image. The processor is electrically connected with the sensor array. The processor is adapted to identify if the captured image contains a specific pattern, and trigger an external device to determine whether the specific pattern matches a predetermined feature when the captured image contains the specific pattern.

摘要： A portable electronic device and an operation method are provided. The portable electronic device includes a body, a screen, a camera, an image sensor and a main system. The image sensor continually captures a first image outside the body with a first resolution and a first power consumption. The camera is turned on in the first state of the portable electronic device by the main system to capture a second image outside the body with a second power consumption and a second resolution only when the face image information appeared for over two seconds on the screen is detected by the image sensor from the first image. The second resolution is higher than the first resolution, and the second power consumption is higher than the first power consumption.

摘要： 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.

摘要： 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.
