Camera system with low delay, less cache and controllable data output mode and method

Abstract

The invention relates to a camera system with low delay, less cache and a controllable data output mode. The camera system comprises a PLL module, a configuration register, a system and logic controlmodule, a photosensitive pixel acquisition control module, a photosensitive pixel matrix module, an analog signal processing module, an A / D conversion module, a digital image processing module, a buffer and an output interface module, wherein the configuration register, the system and logic control module, the photosensitive pixel acquisition control module, the photosensitive pixel matrix module,the analog signal processing module, the A / D conversion module, the digital image processing module, the buffer and the output interface module are sequentially connected; and the system and logic control module is also respectively connected with the PLL module, the A / D conversion module, the digital image processing module, the buffer and the output interface module. According to the scheme ofthe invention, by shrinking the units of image acquisition and output and simplifying the corresponding system logic control, the whole processing procedure is more compact, and the delay and cache space of the camera system and the whole system are reduced.

Description

technical field [0001] The invention relates to the technical field of image sensors for image acquisition and processing, in particular to a camera system and method with low delay, less buffering and controllable data output mode. Background technique [0002] Low-latency video transmission has a wide range of applications, and it is foreseeable that it will shine in the fields of remote driving, autonomous driving, telemedicine, interactive virtual reality, and deep-sea space limit detection. At present, with the increase of network bandwidth, real-time video transmission is a mature technology. However, limited by the processing speed of other links other than network bandwidth, the end-to-end delay is still extremely high, which makes this technology seem to be handicapped in practical applications. In the past, people have spent a lot of time researching video compression technology in order to transmit clearer video with less bandwidth and solve the problem of delay ...
