Description

Driving circuit containing multiple cameras and filming apparatus

Technical field

The utility model is related to webcam driver fields, and in particular to the driving circuit containing multiple cameras and shooting dress It sets.

Background technology

It is known that depth of view information of the mobile phone terminal by dual camera hardware recording photograph, can perceive and be photographed object Distance.So Fuzzy Processing can be done by object and background separation, or even by background, realize that the later stage adjusts the depth of field of photo Function.Certain user can also select any one of photo position to make focus point, to carry out perhaps different photo effects Fruit.Furthermore it is also possible to take the photo (tilt fuselage angle may be viewed by) of 3D effect, and provide the virtual four seasons, 360 degree entirely The functions such as scape shooting.So after all, newly-increased camera is mainly used for realizing first taking pictures focus, perfect scratches figure spelling afterwards The function of figure, seamless special efficacy etc..

Mobile phone terminal on existing market is generally all only taken the photograph double for rear camera, and general is all to adopt With the camera configuration that pixel is one high and one low, low pixel camera only records depth of view information, and when taking pictures as 3D, due to Bore hole 3D shootings need the camera of two same pixels, so one high and one low camera configuration can not accomplish bore hole 3D effects Therefore fruit seriously limits the application of 3D shootings.

The filming apparatus of most significant end in the prior art is also only supported to 3 cameras, and is generally supported big to 2 In the camera of 13M high pixels, and the camera of the two high pixels can only be respectively as one in front and one in back using.

It is experienced from application, it is understood that in captured in real-time bore hole 3D pictures, or when recording 3D videos, typically By the concurrent working simultaneously of two identical cameras, the shooting in different angle under same object is realized, to synthesize 3D effects Fruit.And camera pixel is higher, and 3D effect is more true to nature.So being analyzed based on the above prior art, if high using pixel one One low camera configuration, will seriously affect 3D effect.And if it is desired to if realizing 3D effect self-timer, it is necessary to preposition to take the photograph As head can also support double take the photograph.

Technically, the limitation based on filming apparatus, present mobile phone terminal are generally avoided using identical camera, and And using the camera of low pixel as second camera.Because for from driving circuit control signal, same pixel is taken the photograph As addresses I2C all having the same such as sensor I2C, eeProm i2C in head mould group, multigroup I2C can be resulted in the need in this way It could work normally, and not extra control signal (I2C signals) in the master controller of existing filming apparatus, so as to cause The application of the cameras of multiple same pixels is limited to.

Utility model content

The technical problem to be solved by the present invention is to overcome the shortcomings of existing technology, provide containing multiple cameras Driving circuit and filming apparatus, can realize front camera and rear camera all support bore hole 3D shoot.
