Description
Technical field
The present invention relates to graphics process field, especially a kind of digital imaging system and control method thereof.
Background technology
Along with the continuous progress of science and technology, digital imaging apparatus is the most gradually come in the life of people, and the most common takes the photograph
Camera, DTV etc., it is a kind of equipment of output image signal in a variety of forms after picture signal that will process, in recent years,
Having connected the Internet in each family, DTV is developed rapidly, and it provides a user with polytype content
Service, such as real-time broadcast, content-on-demand (COD), game and video call.
But, owing to the camara module of prior art has the image encoder of separation to compress the image letter of user
Number, in order to reduce the workload of other assemblies of numeral TV, but increase the production cost of camara module.Additionally, separate
Ground transmission is suitable for the picture signal of the user of the format compression of video call and for carrying out the use shown at display unit
The picture signal at family, which increases the bandwidth load of data-interface.
Summary of the invention
For the above, the invention provides a kind of digital imaging system and control method thereof, efficiently solve
State at least one aspect in problem.
Be employed technical scheme comprise that a kind of digital imaging system to realize the purpose of the present invention, including display unit,
VPU, image coding unit, image input units and data-interface, wherein,
Described display unit, output image signal is as image；
Described VPU, the external image signal according to being received by data-interface identifies user
Described image coding unit, encodes the external image signal received from data-interface in a predetermined format；
Described image input units, produces and exports external image that is corresponding with external image and that be not encoded or compress
Signal；
Described data-interface sends the external image signal exported by image input units to display unit.
In some embodiments, user input unit includes
A kind of control method of digital image, including:
A, produce the external image signal corresponding with external image by figure input block；
B, the external image signal produced to display unit transmission with the form not being encoded or compress by data-interface；
C, accepted by VPU data-interface send external image signal and according to external image signal come
Identify user；
