A global positioning system (GPS) device including an antenna and a baseband unit is disclosed. The antenna receives a wireless signal group. The baseband unit processes the wireless signal group to generate a position signal. The position signal is updated every time interval. The duration of the time interval is changed dynamically.

Method, device and vehicle utilizing the same

Methods and systems for adjusting color-saturation contrast of the video signal. Statistical information based on chrominance or luminance measures is analyzed to derive a gain function. The gain function is also determined according to the detection result of an exceptional situation during statistical analysis. The gain function is applied to the video signal to modify the amplitude of the chrominance signal.

Video contrast adjusting method and system

Methods and systems for multi-stage DV encoding and decoding. A skip command may be issued by a microprocessor or DRAM controller via a physical link when DRAM bandwidth is overtaxed. Corresponding encoding and decoding systems implementing the proposed DV encoding or decoding method are also provided.

Methods and systems for DV encoding and decoding

Methods and systems of color image processing for color adjustments. Phase information of a received chrominance signal is detected and applied to adjust saturation and hue of the color by changing the magnitude and phase of the chrominance signal respectively. The phase information of the chrominance signal can also be used to adjust the brightness by changing the magnitude of a received luminance signal.
