The structural representation of a kind of camera embodiment 1 providing referring to the application shown in Fig. 1, this camera is applied to an electronic equipment, this electronic equipment can be the electronic equipments such as desktop computer, notebook, panel computer, mobile phone, intelligent television, intelligent watch, Wearable equipment, in described electronic equipment, has image collecting function.
This camera comprises: the first photosensitive sensor 101, analog-to-digital conversion layer 102, the second photosensitive sensor 103.
Wherein, this first photosensitive sensor 101 is symmetricly set on described analog-to-digital conversion layer 102 both sides and is connected with described analog-to-digital conversion layer 102 respectively with the second photosensitive sensor 103;
Described the first photosensitive sensor 101 when receiving the first enabling signal, receives the incident light of first direction input, and the incident light of first direction input is converted into the first analog electrical signal, and in Fig. 1, the direction of arrow represents incident direction of light.
Wherein, this first photosensitive sensor 101 is positioned at a side of analog-to-digital conversion layer 102, be connected with this analog-to-digital conversion layer, in the time that this first photosensitive sensor 101 receives the first enabling signal, this first photosensitive sensor 101 starts, receive the incident light of first direction incident, and this incident light is converted into the first analog electrical signal.
Described the second photosensitive sensor 103 when receiving the second enabling signal, receives the incident light of second direction input, and the incident light of second direction input is converted into the second analog electrical signal;
Wherein, this the second photosensitive sensor 103 is positioned at the opposite side of analog-to-digital conversion layer 102, be connected with this analog-to-digital conversion layer, in the time that this second photosensitive sensor 103 receives the second enabling signal, this second photosensitive sensor 103 starts, receive the incident light of second direction incident, and this incident light is converted into the second analog electrical signal.
