Abstract

The invention discloses a stable image processing system comprising a image sensor, an image processing circuit connected with the image sensor, a time base generation circuit connected with the image processing circuit, a signal filtering circuit simultaneously connected with the image processing circuit and the time base generation circuit and a bias amplifying circuit connected with the time base generation circuit. The stable image processing system is characterized by further comprising a phase-shift circuit connected with the bias amplifying circuit; the phase-shift circuit comprises a phase-shift chip U2, a triodeVT4, a triodeVT5, a resistor R14, a capacitor C3 and the like; one end of the resistor R14 is connected with a VCC+ pin of the phase-shift chip U2, and the other end of the resistor R14 is connected with an IN1 pin of the phase-shift chip U2; a cathode of the capacitor C3 is connected with the IN1 pin of the phase-shift chip U2 through a resistor R16, and an anode of the capacitor C3 is connected with an IN2 pin of the phase-shift chip U2. Compared with the prior art, the stable image processing system is provided with the phase-shift circuit to ensure processing effect of the processing system as the voltage is unstable, thus image signal distortion after processing never occurs.

Description

technical field [0001] The invention relates to an image processing system, in particular to an image processing system based on a wide pulse trigger circuit. Background technique [0002] Displays are also often referred to as monitors. The display is an I / O device belonging to the computer, that is, an input and output device. It is a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye. Its application is very extensive, ranging from satellite monitoring to watching VCD. It can be said that in modern society, its figure is everywhere. Such as televisions, computers and other electrical appliances will be used. However, the current image processing system installed in the display does not have a good image processing effect when the voltage is unstable, thereby affecting the display effect of the display. Contents of the invention [0003] The object of the present invention is...
