  • Patent number: 9639259
    Abstract: A portable electronic device includes a display unit, a sensing unit, and a signal processing unit. The sensing unit includes a proximity sensor. The proximity sensor detects a distance between an object and the portable electronic device. The signal processing unit is electronically connected to the display unit and the proximity sensor. The signal processing unit switches a scrolling mode of an image displayed on the display unit according to a detection of the proximity sensor.

  • Patent number: 9462187
    Abstract: An electronic device includes a camera module and an image module. The camera module captures a number of static images of an object. The image module includes a detecting unit and an image combining unit. The image module detects an edge response value of each image. The image combining unit selects and combines two images having maximum edge response values in turn according to a rate of the edge response values.

  • Patent number: 9250089
    Abstract: A navigation method for a vehicle includes receiving a destination inputted by a user and establishing a current position of a vehicle using a positioning device. Based on an electronic map, a route from the current position to the destination is determined and characteristic points of the determined route are extracted. A street view mapping of the determined route is acquired. Based on the street view mapping, and using a camera, a marker of each of the characteristic points is extracted using an image extraction method. When the vehicle arrives at each of the characteristic points, a prompt is output for the user by recognizing the marker of each of the characteristic points from the street view mapping.
