[0002] With the development of intelligent and automated projectors, projectors are generally equipped with cameras for operations such as automatic focus, automatic keystone correction, automatic obstacle avoidance and automatic screen entry.

[0003] In recent years, TOF has begun to be used on projectors. TOF is the abbreviation of Time-of-Flight ranging sensor, and its Chinese name is long-distance time-of-flight ranging sensor. It is divided into single-point TOF and multi-point TOF; single-point TOF can test the distance; multi-point TOF can test the angle between the projector and the screen.

[0004] As a new type of sensor device, TOF has high precision and fast response. When installed on a projector, it makes the focus and keystone correction of the projection more agile. Now more and more projector products have the demand to install TOF.

[0005] In order to add TOF to existing projectors, the projector motherboard design is changed, such as adding an IIC interface, which requires two interfaces for communication between the camera and TOF, increasing the cost of the product. Utility Model Content

[0006] The technical problem to be solved by this application is that in order to install TOF, the existing projector needs to change the design of the projector motherboard, such as adding an IIC interface, which results in the camera and TOF requiring two interfaces to communicate, increasing the cost of the product.

[0043] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0044] First, see Figure 1-8 The utility model discloses a camera and TOF integrated module 1, which includes a TOF module 12, a camera module 13, a driving module 11, a connecting module 15, a voltage stabilizing module 14, and a storage module 16. The driving module 11 is electrically connected to the TOF module 12 and the camera module 13 respectively, and the driving module 11 is electrically connected to the connecting module 15; the voltage stabilizing module 14 is electrically connected to the driving module 11 and the connecting module 15 respectively, and the storage module 16 is electrically connected to the driving module 11.

[0045] Specifically, the voltage regulator module 14 is used to power other modules within the module and convert the 5V power supply of the connection module 15 to 3.3V. The storage module 16 is used to store the camera driver program so that the driver module 11 can implement the camera driver program. The driver module 11 is used to drive the camera. The camera module 13 includes a camera lens assembly. The driver module 11 drives the camera module 13 and the TOF module 12 respectively. The driver module 11 transmits signals to the outside of the module by transmitting signals with the connection module 15. It can be understood that the signals driven by the camera module 13 and the TOF module 12 to the outside of the module need to be transmitted through the driver module 11 and the connection module 15.

[0046] It can be understood that in the integrated module, the camera module 13 and the TOF module 12 are simultaneously connected to the driving module 11, and the driving module 11 transmits signals to the connection module 15, thereby achieving an interface to complete communication with the outside world and saving product costs.

[0047] Optionally, the connection module 15 uses a USB interface or a MIPI-CSI interface to connect to external devices. In this embodiment, the connection module 15 uses a USB interface, but the interface of the connection module 15 can select any of the above interfaces to connect to the outside according to actual conditions.

[0048] Optionally, the TOF module 12 adopts either single-point TOF or multi-point TOF, or a combination of the two.

[0049] As an embodiment, the TOF module 12, the camera module 13, the driving module 11, the connecting module 15, the voltage stabilizing module 14 and the storage module 16 are integrated into a circuit board. It can be understood that the TOF module 12, the camera module 13, the driving module 11, the connecting module 15, the voltage stabilizing module 14 and the storage module 16 are an integrated integrated module, which can be directly installed in an electronic device for use. The connection is directly made through the connection port in the connecting module 15 to transmit signals, thereby improving the integration of the module and making subsequent installation more convenient.

[0050] The driving module 11 includes a driving unit 111, a first two-wire communication interface 112 and a first communication interface 113. The first two-wire communication interface 112 and the first communication interface 113 are respectively connected to the driving unit 111. The first two-wire communication interface 112 uses an IIC interface to transmit signals, and the first communication interface 113 uses a data interface. The driving unit 111 uses a control chip to control the operation of the camera and the TOF module 12, and transmits the signals transmitted by the camera and the TOF module 12 to the outside through the connection module 15.

[0051] The E7 and E9 ports of the drive unit 111 transmit the CMOS_SDA signal and the CMOS_SCK signal respectively, and are connected to the first two-wire communication interface 112. The C1, C3, and A7 ports are connected to the voltage stabilizing module 14 respectively. The A3, B4, A5, and B6 ports are connected to the storage module 16. The D2 and E1 ports are used for signal transmission with the connection module 15.

[0052] The TOF module 12 includes a second two-wire communication interface 121 and a TOF unit. The TOF unit is connected to the second two-wire communication interface 121, and the first two-wire communication interface 112 is connected to the second two-wire communication interface 121. It can be understood that the second two-wire communication interface 121 and the first two-wire communication interface 112 match each other, and the first two-wire communication interface 112 and the second two-wire communication interface 121 transmit signals according to the IIC protocol, which can realize the transmission of CMOS_SDA signal and CMOS_SCK signal. The first terminal of the TOF unit is connected to the voltage stabilizing module 14 and is driven by the 3.3V power supply provided by the voltage stabilizing module 14. The ninth terminal and the tenth terminal of the TOF unit are connected to the second two-wire communication interface 121.

[0053] The camera module 13 includes a second communication interface 131 and a camera chip. The first communication interface 113 is connected to the second communication interface 131. The first communication interface 113 and the second communication interface 131 match each other and use a DATA interface to transmit signals between the camera module 13 and the driving module 11.

[0054] The voltage stabilizing module 14 includes a voltage stabilizing unit, the input port of which is connected to the connecting module 15, and inputs a 5V power supply. After voltage transformation by the voltage stabilizing unit, the voltage stabilizing unit outputs a 3.3V power supply to meet the driving voltage of other units in the circuit.

[0055] The connection module 15 includes a connection port, which is connected to an external interface. In this embodiment, the connection port is a USB interface. The VIN terminal inputs 5V power, and the D+ and D- terminals are used to transmit data signals.

[0056] The storage module 16 includes a storage chip, and a first terminal, a second terminal, a fifth terminal, and a sixth terminal of the storage chip are used to connect to the driving module 11 .

[0057] Second, see Figure 9 The present invention discloses a projector 100, which includes the aforementioned integrated camera and TOF module 1 and a main control module 2. The main control module 2 is connected to the connection module 15 of the integrated module. The connection port of the integrated module connection module 15 adopts a USB interface or a MIPI-CSI interface, and the type of connection port of the connection module 15 needs to be selected based on the corresponding existing interface of the main control module 2. The connection port of the connection module 15 is of the same type as the connection port on the main control module 2 and matches each other. Through a single interface, the camera and TOF can be installed in a single projector 100.

[0058] It can be understood that the projector 100 adopts an integrated module, and the signal is transmitted between the internal main control module 2 and the integrated module, which can save a wire during internal installation and reduce costs. In addition, the projector 100 originally only has a USB interface or a MIPI-CSI interface. There is no need to change the design of the projector 100 motherboard in order to install TOF, such as adding an IIC interface, which saves design costs and makes upgrade development more efficient.
