What is a PCI-E image Grabber Card?
The PCI-E image capture card is a device used to convert analog image signals into digital signals and transmit them to a computer. It connects to the computer's host through the PCI Express (PCIe) bus, providing high-speed, high-bandwidth data transmission capabilities, suitable for applications requiring fast and accurate image acquisition and processing.
Working Principle
The working principle of the PCI-E image capture card primarily involves the following steps:
Analog Signal Input: The analog input port receives analog image signals from cameras, scanners, or other image source devices.
Analog-to-Digital Conversion (ADC): Utilizes a high-speed analog-to-digital converter (ADC) to convert the analog signals into digital signals, maintaining signal accuracy and precision.
Signal Processing: A digital signal processor (DSP) processes, analyzes, and encodes the acquired digital signals, extracting useful image information.
Data Transmission: The PCIe interface transmits the processed digital signals to the computer's memory via the PCIe bus for further processing and analysis by software.
