摘要： The present invention provides a device and an image adjustment method by simultaneously adjusting the luminance and the chrominance of an image. The device comprises a luminance analysis device, a contrast adjusting device, a luminance adjusting device, a chrominance compensation device and a luminance gain adjusting device. The method comprises steps of: generating a maximum input luminance signal, an average input luminance signal and a minimum input luminance signal according to an input luminance signal; generating a contrast value according to at least one of the maximum input luminance signal and the average input luminance signal; generating an input luminance offset according to the input luminance signal and the minimum input luminance signal; generating an output chrominance signal according to the contrast value and an input chrominance signal; and generating an output luminance signal according to the input luminance offset and the contrast value.

摘要： A keyboard control system that contains a manufacturer's identification code and a multiple selection matrix. This invention utilizes all the existing LED leads on a keyboard controller. Using the period between initial setting and normal operation together with triggering signals, user or customer is able to pick up suitable data from a single keyboard controller. In addition, the invention is capable of using the same leads for connecting to external serial EEPROM so that new data not included among the preset data within the keyboard controller can still be input to the controller. Furthermore, the same type of technique can be used to increase the number of combinations in different application areas as long as more keyboard controller input/output ports are available.
摘要翻译：包含制造商识别码和多重选择矩阵的键盘控制系统。本发明利用键盘控制器上的所有现有LED引线。使用初始设置和正常操作之间的时间以及触发信号，用户或客户能够从单个键盘控制器拾取合适的数据。此外，本发明能够使用相同的引线连接到外部串行EEPROM，使得不包括在键盘控制器内的预设数据中的新数据仍然可以输入到控制器。此外，只要更多的键盘控制器输入/输出端口可用，可以使用相同类型的技术来增加不同应用领域中的组合数量。
