Abstract: A method for displaying a video image includes: receiving the video image and performing a real-time detection upon the video image to detect at least a contour section in the video image; determining a compensation characteristic according to the contour section; adjusting pixel values of pixels corresponding to the contour section according to the compensation characteristic; and displaying the adjusted video image.

Abstract: A display apparatus outputs a video frame according to ambient brightness. The display apparatus includes an ambient sensor for sensing the ambient brightness of the display apparatus to generate an ambient brightness sensing signal; and a control circuit, coupled to the ambient sensor, for dynamically adjusting display characteristics of the video frame according to the ambient brightness sensing signal without adjusting a light source of the display apparatus. ? (gamma) curve characteristics of the display apparatus can be adjusted to change the display characteristics (brightness and color temperature) of the outputted video frame without causing any damage on the light source hardware (such as the cold cathode fluorescent lamp (CCFL)).

Abstract: The present invention provides an image processing method for a display device. The method includes: calculating an average brightness of an image; adjusting the average brightness to generate an adjusted average brightness; utilizing Brightness Preserving Bi-Histogram Equalization (BBHE) and the adjusted average brightness to process the image; and displaying the image.

Abstract: A boost converter includes a first boost conversion unit and a second boost conversion unit. Coils of the first boost conversion unit and the second boost conversion unit are coupled with each other. Due to coupling of the coils, the second boost conversion unit releases energy while the first boost conversion unit stores energy in a period of time. Furthermore, due to coupling of the coils, the first boost conversion unit releases energy while the second boost conversion unit stores energy in another period of time. The two boost conversion units operate alternately, thereby adjusting switching loss and averaging output power of components. Furthermore, as switching frequency increases, the coil inductance, as well as the capacitance required in the two boost conversion units can be reduced correspondingly, thus substantially enhancing responses of the two boost conversion units as a whole.
