Problems solved by technology

[0009] From Table 1, it is obvious that using a low-end or high-end CPU to process the image will cause severe CPU overload
Therefore, the video frame data of 30 HD frames per second captured by the known camera module cannot be processed smoothly by high-end or low-end CPU.

Abstract

The invention provides an image capturing device and image communication method which are applicable to video conference. The video conference is built between a local terminal and a remote terminal through network. The image capturing device comprises a processor, a video compressor, an encryption element and a data transmission interface, wherein the processor is used to process an original video signal to generate a first video signal and a second video signal; the video compressor is used to receive and compress the first video signal; the encryption element is used to encrypt the compressed first video signal; the data transmission interface is used to transmit the compressed and encrypted first video signal and the second video signal to the local terminal; and the first video signal is transmitted to the remote terminal through the local terminal and network and is fed back through the remote terminal, and the second video signal is displayed on the local terminal.

Description

technical field [0001] The present invention relates to an image capture device and an image communication method suitable for video conferencing, and in particular to an image capture device and an image communication method that can provide real-time without increasing computer load. Background technique [0002] With the rapid development of technology today, video conferencing has become a tool for many companies and people to communicate with each other remotely and online. Therefore, high-resolution images have become a demand. However, due to the limitations of the current hardware architecture and network bandwidth, the transmission process is easily affected by computer processing efficiency and network bandwidth, and the quality is often not very good. Generally speaking, a high-resolution (high definition, HD) image refers to a resolution of a picture of more than 1280*720 pixels. However, when a device for traditional video conferencing captures a high-resolutio...
