    • The present invention is directed to the provision of an information input apparatus that can change the projection position of an input image by tracking a target object and can detect an information input to the input image. More specifically, the invention provides an information input apparatus includes a projection unit which projects an input image, a projection position changing unit which changes the projection position of the input image, a detection sensor which detects the position of a detection target, and an information detection unit which causes the projection position changing unit to change the projection position of the input image by tracking the position of the detection target detected by the detection sensor, and which detects an information input to the input image based on data supplied from the detection sensor.
    • 本发明旨在提供一种信息输入装置,其可以通过跟踪目标对象来改变输入图像的投影位置,并且可以检测输入到输入图像的信息。 更具体地说,本发明提供了一种信息输入装置,包括投影输入图像的投影单元,改变输入图像的投影位置的投影位置改变单元,检测检测对象的位置的检测传感器,以及信息 检测单元,其使投影位置改变单元通过跟踪由检测传感器检测到的检测目标的位置来改变输入图像的投影位置,并且基于从检测传感器提供的数据来检测输入到输入图像的信息 。

    • A comparator has P-channel field effect transistors that are supplied at respective gates with input voltages Vin and Vref, which are objects of comparison, and that act as a differential transistor pair; and N-channel field effect transistors that serve as current channels for respective drain currents of these two P-channel field effect transistors and that act as a current mirror circuit. The comparator outputs a drain voltage Vx of an N-channel field effect transistor as a signal showing a result of comparison between the two input voltages. An N-channel field effect transistor diode-connected to the comparator is interposed between drains of the N-channel field effect transistors.
