Video recording method and system for synchronously recording pictures and sound

Abstract

The invention provides a video recording method and system for synchronously recording pictures and sound. The method provided by the invention comprises the following steps: if a starting instruction input by a user is received, sending a recording starting instruction to a recording module, at the same time, according to a preset shooting time interval, cyclically sending a picture acquisition instruction to a picture acquisition module; receiving sound data output by the recording module, receiving picture data output by the picture acquisition module, and recording acquisition time when the picture data is acquired and time information when the sound data is acquired; and according to the acquisition time and the time information, mapping the picture data to corresponding time points of the sound data so as to obtain mixed data integrated with the picture data and the sound data. According to the invention, the video recording method and system for synchronously recording the pictures and sound can record high-definition static images and continuous onsite sound at different time, and the images can be intelligently corresponding to recordings of the same period.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a video recording method and system for synchronously recording pictures and sounds. Background technique [0002] At present, electronic products such as taking pictures, video recordings, and recordings have become necessary recording equipment for journalists, lecturers, business people, college students and other groups. By taking pictures, video recordings, and recordings, their learning, work, and communication can be recorded. , and playback and review when needed. Modern people pay more and more attention to children's education. Due to the relatively tight classroom teaching time, and teachers face a lot of content to be taught, their teaching or writing speed is often relatively fast, resulting in some students not being able to grasp what they have learned in time and complete classroom records notes. In order to improve academic performance, many parents...

Problems solved by technology

[0003] As we all know, in the two recording methods of photography and video recording with the same specification lens, the picture quality and clarity of the picture file is much better than that of the video file, and the data volume of the video file is too large, which requires higher storage space and system power consumption of the device; simply The sound recording equipment can only record sound information, but cannot record live images; the photographic equipment can only record live images, and cannot perform on-site recording
