The invention provides a projection camera and a method for recording information thereof, wherein the projection camera comprises an audio signal receiving unit for receiving sound and converting the sound into an audio signal, a projection signal receiving unit for receiving a projection signal, a signal processing unit for compressing the projection signal and the audio signal into a video flow with a predetermined format, and a video flow output unit for outputting the video flow. By adopting the technology provided by the optimized embodiment of the invention, the invention can directly obtain a digital projection signal, and meanwhile, a microphone is built in the projection camera or a projection camera remote controller, therefore, the project camera is easy to hoist and only needs to add a corresponding interface and a signal processing unit without using an expensive camera head so that the content of projection, the explanation of a hierophant and the voice interacted by people on site can be recorded more conveniently to be shared by more people.
Description
technical field [0001] The invention relates to projector technology, in particular to a projector and a method for recording projector information. Background technique [0002] Now projectors have been widely used in lectures, trainings, conferences, press conferences, etc. The reason why people use projectors is to let more people see what they want to show, but due to time and space constraints, many People cannot attend in person, so there is an urgent need for a technology that can record the projected content, the commentator's explanation, and the voice of the live interaction with people to share with more people. [0003] On-site shooting requires additional camera equipment and camera personnel, and the projected content is interfered by the external light on site and the performance of the projector (such as brightness and clarity), resulting in unclear images and requiring post-production. The commonly used slideshow (PPT, PowerPoint) technology can only be lim...
