Abstract
Description
[technical field]
[0001] The invention relates to a video recording method, in particular to an infinite time video recording method of a hand-held device with a camera function. [Background technique]
[0002] Hand-held devices with a camera function include mobile phones and PDAs that can take pictures, and the principles of taking pictures are basically the same. The processing capabilities of these handheld devices with camera functions are generally weak, so the overall hardware solution is mostly: handheld device main chip + front-end image processing chip (Backend IC) + image sensor (Sensor). Among them, the Backend IC completes the acquisition of Sensor data and Jpeg compression. In order to make the handheld device not only have a camera function but also video recording, a technology of using the Motion Jpeg format to realize video recording has emerged. The downside of recording with Motion Jpeg is that the audio file cannot be recorded simultaneously. Generall...
