Embodiment Construction

[0053] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0054] refer to Figure 9 , in existing application scenarios, video calls are usually performed through the steps shown in the figure. The image acquisition device first collects MJPEG images in real time, and transmits the collected images to the middle layer of Camera. The middle layer of Camera is used for fault tolerance, scheduling and filtering of the collected data; for the distribution and other processing of the decoded data, these operations are completed by the CPU;

[0055] Wherein, the step of decoding is carried out by the image decoder, and the decoded image data includes the MJPEG image collected locally and the H264 video stream from the remote en...

Abstract

A camera middle layer image processing method and system-on-a-chip, by adding fault-tolerant processing, repairing abnormal or missing video data in advance, reducing the probability of error reporting when decoding video data, and then performing hardware decoding through a decoder as much as possible, reducing calls for software decoding probability, improving the decoding performance of the SoC. At the same time, the present invention also adds a filtering process to meet the requirements of subsequent modules and improve system display performance. In the present invention, the multi-core central processing unit of the system on chip is bound to different threads respectively, so as to realize the parallel operation of software and hardware, and further improve the display performance of the system on chip. In addition, from the perspective of display quality, because the present invention selects a better decoding data format for the system-on-chip, the present invention can further provide higher display quality while ensuring display performance.

Description

technical field [0001] The present invention relates to Camera intermediate layer technology, in particular to an image processing method and an on-chip system of Camera intermediate layer. Background technique [0002] With the popularity and development of embedded mobile networks, the functions of the System on Chip (SoC, System on Chip) in embedded devices are becoming more and more powerful. Therefore, the application of embedded devices is becoming more and more extensive. For example, users can A variety of multimedia applications (APP, application), such as video call APP, online meeting APP, etc., are installed in the embedded system, so as to communicate with each other in real time. Taking online conferences as an example, the requirements for the effect of image display are very high, so the real-time and fluency of image display are important indicators for people to measure and purchase embedded devices. [0003] The application scenario of an online conferenc...
