Do not have a detailed description.
A kind of structural representation of the photographic head embodiment 1 provided referring to the application shown in Fig. 1, the photographic head are applied to
One electronic equipment, the electronic equipment can be desktop computer, notebook, panel computer, mobile phone, intelligent television, intelligent watch, wearing
The electronic equipments such as formula equipment, have image collecting function in the electronic equipment.
The photographic head includes：First photosensitive sensor 101, analog digital conversion layer 102, the second photosensitive sensor 103.
Wherein, first photosensitive sensor 101 and the second photosensitive sensor 103 are symmetricly set on the analog digital conversion layer
102 both sides and it is connected with the analog digital conversion layer 102 respectively；
When first photosensitive sensor 101 is used to receive the first enabling signal, the incidence of first direction input is received
Light, and the incident illumination that first direction is input into is converted into into the first analog electrical signal, in Fig. 1, the direction of arrow represents the side of incident illumination
To.
Wherein, first photosensitive sensor 101 is located at the side of analog digital conversion layer 102, is connected with the analog digital conversion layer, when

The connection of chip and the second circuit and the first chip.
In actual enforcement, the interface can be using mipi (mobile Industry Processor Interface, Mobil Industry
Processor Interface) agreement, do not limit in the present embodiment.
In practical application, the first direction and second direction of photographic head can correspond to outdoor scene direction and user direction respectively, should
When user direction is that user uses the electronic equipment, user is in the direction of the electronic equipment, typically defeated with the electronic equipment
Enter the directions such as region, touch screen consistent, the outdoor scene direction is in opposite direction with the user.
It should be noted that the performance parameters of first camera lens can be higher than second camera lens, this is because, in reality
During border is implemented, the user direction typically collection for user's auto heterodyne image closer to the distance or video image etc., camera lens is required
Than relatively low, and outdoor scene direction is the images such as distant scenery, in order to ensure the definition of shooting image, needs performance parameters
Higher camera lens, it is therefore desirable to the performance parameters of the first camera lens are higher, and the second camera lens need not be higher.
Certainly, in the present embodiment, the performance parameters of the first camera lens are higher than second camera lens, but are not limited to this, the two
Performance parameters also can be consistent, and the performance parameters of first camera lens can also be less than second camera lens, and particular situation can basis
Practical situation is configured.
In the present embodiment, the first chip also includes interface, and is connected with first line and the second circuit by the interface respectively
Connect, the unlatching of the interface is consistent with the enabling signal that control photosensitive sensor receives incident illumination so that the letter of circuit connection
Number transmission is consistent with the unlatching of photosensitive sensor so that associate between the two, it is ensured that the signal transmission in image acquisition process
It is unimpeded.
A kind of structural representation of camera module embodiment 3 as shown in Figure 7, the camera module include：First mirror
