1. Overview
The CVBS video crosshair overlay controller is a product introduced by Ning Pengda for superimposing crosshairs on video images. Crosshairs refer to two perpendicular intersecting lines, which primarily serve functions such as centering, reference, marking, and zoning in general applications. With the increasing variety of video products and the broadening of application fields, superimposing crosshairs on the original video image can enhance the functionality and improve the usability of many video products. The CVBS video crosshair overlay controller is manufactured using semiconductor devices and related technologies combined with modern electronic manufacturing processes, offering advantages such as convenience, flexibility, and low cost. It also addresses the limitation of traditional OSD ICs, which cannot overlay full-screen continuous lines.
