Abstract: An image processing method and an image processing system for eye-gaze correction are provided. The method is applicable to an image processing system having a screen and an image capturing device and includes the following steps. A user's face in front of the screen is captured by the image capturing device to generate a facial image. A head offset and an eye-gaze position of the user with respect to the screen are obtained based on the facial image so as to accordingly determine whether to correct the facial image. If yes, the facial image is corrected based on the eye-gaze position and a preset codebook to generate a corrected facial image, where the preset codebook records correction information of multiple preset eye-gaze positions.

Abstract: A buck voltage regulator control circuit for a single-input multi-output direct current power supply system, during a soft start phase of a first buck voltage regulator of the power supply system, the buck voltage regulator control circuit controls a first high side switch of the first buck voltage regulator to switch to a turned-on state from a turned-off state when a second high side switch of a second buck voltage regulator is in the turned-off state. Therefore, the first and second high side switches are not simultaneously switched to the turned-on state from the turned-off state to reduce inrush current.

Abstract: An amplifying circuit for analog to digital converter with multi-stage conversion range is used for dividing an analog input voltage into multiple voltage ranges to perform signal amplification and attenuation according to multiple magnifications (e.g., amplify the analog input voltage with low voltage level, and attenuate the analog input voltage with high voltage level). The analog to digital converter performs analog to digital conversion to the analog input voltage with amplification or attenuation to generate a digital bit with amplification or attenuation, and then generates an output digital bit according to the digital bit and the magnification. As a result, the analog to digital converter is adaptive to the analog input voltage with high voltage level, and precision and quantization error of the analog input voltage with low voltage level can be maintained as well.
