  • Publication number: 20190188500
    Abstract: An apparatus for monitoring an object in a low light environment includes an image capturing unit, a vehicle speed unit, an image recognizing unit, and an object determining unit. The image capturing unit continuously captures and outputs time-sliced images. The vehicle speed unit detects and outputs current vehicle speed information. The image recognizing unit recognizes a region having pixel brightness higher than a threshold in each of the time-sliced images and marks the region as a high brightness block. The object determining unit selects at least two successive time-sliced images having high brightness blocks in a continuous corresponding variation relationship from the time-sliced images, generates and outputs estimated speed information, and when the estimated speed information is different from the current vehicle speed information, determines that the high brightness block is a moving object block and monitors the moving object block.

In the present method, first, a touch trajectory generated by continuously touching a touch panel of the electronic device is detected, wherein the center of the touch panel is a display area, and a non-display area surrounds the display area. Then, whether the touch trajectory is started from one side of the non-display area and passed through the display area to be extended to another side of the non-display area is determined. If so, the display area is split according to the touch trajectory to display at least two windows frames. As a result, an intuitional and convenient method for generating multiple windows frames in the display area is provided, and the operation of the electronic device is made very convenient.

    Abstract: A method and an apparatus for dynamically adjusting a viewing angle of a screen are provided. The method is suitable for dynamically adjusting a viewing range of a screen of a handheld electronic device, wherein the viewing angle of the screen is adjustable. The method is as follows. First, a shifting value of a target deviating from the viewing range of the screen is detected by a sensor. Next, the viewing range of the screen is dynamically adjusted according to the shifting value, so as to cover the target within the viewing range of the screen. Accordingly, the snooping for the content of a frame displayed on the screen by others can be prevented and a user can view the frame displayed on the screen more conveniently.
