dec exceeds a predetermined time; (b) the battery is in the charging state and the decrease of the voltage exceeds a predetermined voltage; and (c) the battery is in the discharging state and the rate of the decrease of the voltage exceeds a predetermined decline rate.
This invention is suitable for use in the field of integrated circuits. It provides a type of power source circuit. Said power source circuit includes: a charge pump circuit used to operate the charge pump to produce driving voltages; a first control circuit, used in the closed-loop control of said charge pump circuit to produce a positive high voltage; a bias-ratio circuit, used with the positive high voltage and the zero-potential voltage produced by the first control circuit to produce a positive sub-high voltage and a lowest positive high voltage; and a second control circuit, used in accordance with the positive sub-high voltage and the lowest positive high voltage produced by said bias-ratio circuit in the closed-loop control of said charge pump circuit to produce a negative high voltage. Using this invention, the system contains no voltage higher than the liquid crystal's driving voltages, and also does not contain any lower negative voltage than the liquid crystal's highest negative driving voltage, thereby reducing the circuit's electrical consumption.
2C bus. Each driver integrated circuit can directly drive a stepper motor and it can also drive different numbers of stepper motors using different channels. In particular, the multi-channel stepper motor driver integrated circuit has fewer input contact points and thus it clearly reduces the chip area as well as the manufacturing cost which allows the chip to be used in a wide range of digital equipment and electronic information products where space is limited such as with cellular phone photo modules.

Color interpolation methods for correcting outlying values
This invention of a color interpolation method for correcting color values of an image, comprising the steps of: constructing a color interpolation matrix having a plurality of points and a center point as an interpolation point, where each point being expressed by one known color and two unknown colors; correcting the known color value of the center point as a function of the color values of the center point and the points in the matrix having the same known color; choosing the horizontal direction or the vertical direction with respect to the center point as the benchmark direction for interpolation calculation; and interpolating one or more unknown color values of the center point as a function of the known color values of the points in the benchmark direction and the known color value of the center point.

Method and system for color correction for a display terminal
A method and system relating to color correction for the display terminal of a display device, such method includes a master control unit generating color adjusting ratios, a display driver using the color adjusting ratios to perform color calibration, and a display panel displaying the resulting colors. Specifically, the master control unit generates adjusting ratios for the RGB color data and the display driver separately adjusts each color according to the percentage of R, G, and B in the ratio to generate a resulting pixel voltage. The system consists of a master control unit, a display driver, and a display panel. The master control unit contains an initialization block, having the following special characteristics: a master control unit with a color adjusting module that receives the color adjusting ratio sent from a color setting block, adjusts color data according to the adjusting ratio, generates the resulting pixel voltage, and displays the colors via a display panel. This invention is easy to operate, inexpensive to produce, and highly practicable.
