Method for realizing use of MIPI (Mobile Industry Processor Interface) lens in wearable equipment

Abstract

The invention discloses an MIPI (Mobile Industry Processor Interface) signal processing system. An MIPI interface is directly connected to an FPGA (Field Programmable Gate Array), so that an image processing function is directly realized after a signal is processed by the FPGA, and a differential signal of MIPI data transmission is directly received through an HS (High Speed) receiving end. Meanwhile, a line in the differential signal is led out and connected to an LP (Low Power) receiving end to perform data reception. An appropriate FPGA pin constraint type is selected according to the differential signal and an LP component to acquire a signal of a special level. Time sequence integration, row-field separation and data integration processing are performed on the MIPI signal overlapped with various types of information to separate row and field synchronization signals in order to perform time sequence integration. An image signal is decoded into a general LVCMOS signal according to integrated information, and imaging is performed.

Description

technical field [0001] The invention relates to the field of camera picture processing, in particular to combining the interface of the MIPI protocol with FPGA, and using the FPGA to directly realize the image processing function. Background technique [0002] Future products will develop towards the mobile direction. As time goes by, many interface standards have emerged, such as UART protocol, I2C, I2S, SPI, SDIO, etc. At the same time, various camera sensors have emerged. For the parallel interface related to the display, a variety of different interface standards lead to design confusion. Designers of mobile devices may have to deal with as many as five conflicting proprietary physical layer interfaces when designing a functional system. A variety of different standards is not conducive to the interconnection and interoperability of device interfaces, and also limits the choices of product developers. MIPI (Mobile Industry Processor Interface) is an open standard for m...
