at least two signal transmitters 3, which are respectively arranged on the circuit board assembly along the first direction and the second direction and are respectively connected with signal output assemblies with the same arrangement direction through connecting lines, no overlapping or crossing region exists between at least part of the connecting lines arranged along the first direction and at least part of the connecting lines arranged along the second direction, the signal transmitters 3 are simultaneously connected with the processing equipment so as to transmit electric signals to the processor, and the processor generates images based on electric signal processing.

The electronic device in this embodiment may be a mobile terminal such as a notebook computer and a mobile phone, a tablet computer, a monitoring device, a device for face recognition, and the like, and is not particularly unique, and any electronic device having an image acquisition requirement may be applicable to the camera mechanism in this embodiment. The electronic device of this embodiment is installed with a processor, which may be a chip that the electronic device itself has and is used for processing data generated by its system, or another independent processing device that is additionally installed, or a chip that is used for implementing image data processing in the original camera shooting mechanism is installed outside the electronic device, and the installation manner of the processor is not unique, which may be determined according to actual situations, and if the electronic device itself does not have a processor, a processor may be additionally installed for implementing image data processing, or if the workload of the electronic device itself processor is too large, a processor may be additionally installed to implement image data processing. The added processor can process not only image data, but also data generated in the electronic equipment. Further, the camera mechanism in this embodiment includes a circuit board assembly, which may be a whole circuit board or formed by splicing a plurality of circuit boards. The lens 1 is mounted on the circuit board assembly and used for receiving optical signals. The image sensor 2 is mounted on the circuit board assembly, and may be mounted in a face-up or flip-chip manner, and the specific mounting manner is not exclusive. The image sensor 2 in this embodiment may be a CCD (charge-coupled device), a charge-coupled device, a CMOS (complementary metal oxide semiconductor), or other types of image sensors 2. The image sensor 2 is provided with a signal output component at least in a first direction and a second direction, for example, a plurality of signal output pins are respectively arranged in the first direction and the second direction, assuming that the image sensor 2 is rectangular, the first direction and the second direction may be a direction in which a first side of the image sensor 2 is located, a direction in which a second side of the image sensor 2 is located, and the like, although the setting is not unique, and the specific direction position may be determined according to an actual shape structure of the image sensor 2, and the like. The image sensor 2 in this embodiment is configured to correspondingly convert light rays, i.e., optical signals, introduced by the lens 1 into electrical signals, and output the electrical signals through a set signal output component.

The signal transmitter 3 is disposed on the circuit board assembly along the first direction and the second direction, and is connected to the signal output assembly having the same direction through a connection line, that is, connected to the signal output assembly nearby. By arranging the signal transmitter 3 in the above manner, a small number of lines can be arranged to connect the signal output assembly and the model transmitter, so that the electric signals can be successfully led out of the circuit board assembly, and under most conditions, no overlapping or crossing region exists between the connecting lines arranged along the first direction and the connecting lines arranged along the second direction. In some special scenarios, due to practical needs, a small number of connecting lines need to be crossed or overlapped, when signals transmitted by a certain two connecting lines need to be combined to form a signal, the two connecting lines need to be commonly introduced into the same signal receiving pin in the signal transmitter for signal transmission, or the space for installing the camera mechanism is specially-shaped, so that a part of the connecting lines in the second direction need to be connected to the signal transmitter in the first direction for signal transmission, and the like. When the electrical signal is output from the image sensor 2 and enters the signal transmitter 3, the electrical signal is transmitted to the processor by the signal transmitter 3, and the processor generates an image signal based on the electrical signal.

Based on the disclosure of the above embodiment, it can be known that the beneficial effects of this embodiment include that the camera mechanism only includes the circuit board assembly, and the lens 1, the image sensor 2 and the at least two signal transmitters 3 which are installed on the circuit board assembly, remove the device used for processing and generating the image in the previous camera mechanism, and make the processor in the electronic device where the camera mechanism is located act as the image processor to generate the image, so not only the efficient utilization of the processor in the electronic device is increased, but also the size of the camera mechanism can be greatly reduced on the premise of ensuring the good and stable performance of the camera mechanism, the camera mechanism is supported to be made narrower and thinner, and then the space for installing the camera mechanism in the electronic device is reduced, so that the electronic device can be made thinner as well.

In addition, since the image sensor 2 is provided with signal output components at least in the first direction and the second direction, at least two signal transmitters 3 in the embodiment are also arranged on the circuit board assembly along the first direction and the second direction respectively and are connected with the signal output components in the same arrangement direction through connecting lines respectively, so that the signals transmitted by the image sensor 2 can be connected with the nearby signal transmitters 3 to transmit the signals to the processor. This kind of setting can be so that the wiring volume on the circuit board assembly significantly reduces, easily lays wire, ensures to have no overlapping or cross region between whole or most interconnecting link that lays along the first direction and whole or most interconnecting link that lays along the second direction, and then has effectively avoided the circuit to cross to arrange, and the phenomenon of thickening mechanism of making a video recording takes place.

If the two groups of signal output components are two groups of signal output pins, the two groups of pins are respectively and uniformly distributed on the first side edge and the second side edge of the image sensor 2 along the length direction of the corresponding side edges.

Of course, the arrangement mode of the signal output components and the arrangement directions of the first direction and the second direction are not limited to the above embodiment, and for example, the arrangement directions of the two sides of the image sensor 2, which form an included angle of 90 °, may also be the first direction and the second direction. Or the image sensor 2 may have a circular shape, a polygonal shape, or the like, and the first direction and the second direction may be directions in which two sides forming an angle of 120 °, 70 °, 160 °, or the like, or directions in which two arc sides corresponding to two sector regions forming an angle of 120 °, 70 °, 160 °, or the like, respectively, are disposed. The direction of arranging the signal output components is not limited to the first direction and the second direction, and may include a plurality of directions such as a third direction and a fourth direction, and the specific direction is the same as the first direction and the second direction. Through having reduced image processor's setting for the inner space of mechanism of making a video recording has obtained the increase, even image processor is great, when signal output pin is more, the mechanism of making a video recording in this implementation also can satisfy its installation, the wiring demand, and in addition, even set up two, a plurality of image processor also can be supported.

The overlapped parts of the first circuit board 4 and the second circuit board 5 are respectively provided with connecting contacts which are connected with each other for transmitting signals, as shown in fig. 2, a plurality of connecting contacts are respectively arranged on the surfaces of the first side edge and the second side edge along the length direction of the first side edge and the second side edge. The signal output components on the image sensor 2 are respectively connected with the corresponding connecting contacts on the first circuit board 4, for example, the signal output components in the first direction are connected with the connecting contacts in the first direction, and the signal output components in the second direction are connected with the connecting contacts in the second direction. The connection contacts are preferably arranged in one-to-one correspondence with the signal output pins.

The signal output components of the image sensor 2 are lapped with the signal contacts 7 to be connected with the corresponding signal transmitters 3 through the signal contacts 7. Or, only one mounting hole is opened on the first circuit board 4, the image sensor 2 is disposed in the mounting hole, the lens 1 is disposed above the image sensor 2, and the I-signal transmitter 3 is directly connected to the signal output component of the image sensor 2 through a circuit disposed on the first circuit board 4.
