The existing camera and projector all-in-one machines are rarely available in the market, or the camera and projector all-in-one machines are only simply assembled together at most, and the camera and the projector are not organically and deeply fused. In order to solve the above problem, the present application provides an all-in-one machine for camera shooting and projection, which organically integrates parts of camera shooting and projection functions, and especially integrates an outermost camera lens and a projection lens into a whole, so that the camera shooting and the projection can share the same external lens.

Fig. 1A is a schematic structural diagram of an all-in-one camera and projector according to an embodiment of the present application. As shown in the figure, the camera and projector all-in-one machine comprises: an outer lens 100, a transreflective assembly 200, a camera assembly 300, and a projection assembly 400;

the transflective assembly 200 is configured to guide light entering through the outer lens 100 to the image capturing assembly 300, and guide light projected by the projection assembly 400 out of the outer lens 100, so as to implement image capturing and projection through the same outer lens 100.

It should be noted that, in order to implement the corresponding functions of the transflective assembly 200 for guiding the light entering through the outer lens 100 to the image capturing assembly 300 and guiding the light projected by the projecting assembly 400 out of the outer lens 100, so as to implement the functions of image capturing and projection through the same outer lens 100, various implementable embodiments are proposed in the present application, specifically as follows:

first embodiment

The transflective assembly 200 is a lens that reflects light on one side and transmits light on the other side, as shown in fig. 1A. The lens can reflect the light entering from the outer lens 100 to the camera module 300, and transmit the light projected by the projection module 400 to the outside of the outer lens 100.

Wherein the lens is set with a certain inclination angle relative to the outer lens 100; adjusting the tilt angle can adjust the path of the light reflected by the lens, so that the light received by the camera module 300 and the light projected by the projection module 400 are not on the same axis. For example, the lens shown in fig. 1A reflects the incident light to the right, and in practice, the lens can be designed to reflect the incident light to other directions, such as left, upward, downward, upward left, downward right, and so on, and the overall structure changes accordingly, which can also achieve the same effect.

In the present embodiment, the external lens 100 represents one or a group of lenses, and is shared by the image capturing device 300 and the projection device 400. The lens is a special lens, and most of light rays are reflected when entering from one side; when light enters from the other side, most of the light is transmitted.

The working principle is as follows: when in shooting, external light enters the machine through the outer lens 100 and is reflected to the shooting component 300 through the lens, so that the shooting function is completed; during projection, light projected by the projection assembly 400 is transmitted out through the lens and passes through the outer lens 100 to complete the projection function.

Second embodiment

As shown in fig. 1B, the transflective assembly 200 is a single-sided mirror, and is disposed at a certain inclination angle with respect to the outer lens 100; when the single-sided reflector is at a predetermined position, the light entering through the outer lens 100 can be reflected to the camera module 300 or the light projected by the projection module 400 can be reflected to the outside of the outer lens 100; when the single-sided reflector is moved away from the predetermined position, the light projected by the projection module 400 can be directly emitted out of the outer lens 100, or the light entering through the outer lens 100 can be directly emitted into the camera module 300.

In this embodiment, on the basis of achieving both reflection and transmission, the transflective assembly 200 may also be a single-sided reflective mirror, and by moving the position, when the reflective assembly is at a predetermined position, the reflective assembly achieves a reflective function, and when the reflective assembly leaves the predetermined position, the light rays are directly emitted, that is, the transmissive function is achieved. For example, the movement control of the single-sided mirror can be realized by physical keys or mechanical structures.

Third embodiment

As shown in fig. 1C, the transflective assembly 200 is a frame structure that rotates at a constant speed according to a certain rotation frequency, and a single-sided mirror is embedded in a part of the frame, and another part of the frame is a hollow region.

The shape of the frame structure is any shape such as a polygon, a circle, an ellipse and the like. For example, when the frame structure is circular, the single-sided mirror and the hollow region are each semicircular, as shown in FIG. 2A; when the frame structure is square, the single-sided mirror and the hollow area are each half square (one rectangle) as shown in fig. 2A. The circles used in fig. 1C are for illustration purposes only and are not limited to circles.

In the present application, the frame structure may be rotated around a circle center or a diameter (as shown in fig. 1C). By contrast, the overall effect of rotating around the center of a circle is better.

Under the condition that the circular frame structure rotates around the center of a circle, when the single-sided reflector of the frame structure rotates to the light path, the light entering through the outer lens 100 can be reflected to the camera assembly 300; as the frame structure continues to rotate, when the hollow area of the frame structure rotates to the light path, the light projected by the projection module 400 can be directly emitted out of the outer lens 100;

or,

when the single-sided reflector of the frame structure is rotated to the light path, the light projected by the projection assembly 400 can be reflected out of the outer lens 100; as the frame structure continues to rotate, when the hollow area of the frame structure rotates to the light path, the light entering through the outer lens 100 can be directly incident into the camera module 300.

The camera module 300 sets a corresponding acquisition frequency according to the preset frequency; the projection module 400 sets a corresponding projection frequency according to the preset frequency.

For example, the frame structure rotates at a constant speed of 24 cycles per second to correspond to alternate capture and alternate projection of 24 frames per second (where 24 frames per second are captured or projected, the human visual perception still keeps the picture smooth).

For another example, in a case where the circular frame structure rotates around a diameter, when the frame structure rotates to a certain inclination angle, such as 45 ° with respect to the external lens 100, the single-sided mirror of the frame structure can just reflect the light entering from the external lens 100 to the image capturing module 300, or the light projected by the projection module 400 just reflects the light to the external lens 100. Meanwhile, the hollow area of the frame structure can directly emit the light emitted by the projection module 400 to the outer lens 100, or directly emit the light entering from the outer lens 100 to the camera module 300.

Fourth embodiment

On the basis of fig. 1D, the frame structure also comprises a stationary embodiment. Specifically, the transflective assembly is a stationary frame structure, and has a certain inclination angle with respect to the outer lens 100; a single-sided reflector is embedded in the frame in a sub-area, and the rest area is a hollow area;

the single-sided reflector of the frame structure can reflect light entering through the outer lens 100 to the camera module 300; meanwhile, the light projected by the projection assembly 400 is directly emitted out of the outer lens 100 through the hollow area of the frame structure;

or, the single-sided reflector of the frame structure can reflect the light projected by the projection assembly 400 out of the outer lens 100; meanwhile, the light entering through the outer lens 100 is directly emitted to the camera module 300 through the hollow area of the frame structure;

in this embodiment, the shape of the frame structure may be any shape such as a polygon, a circle, and an ellipse. The circles used in fig. 1D are for illustration purposes only and are not limited to circles.

In this embodiment, a single-sided mirror is embedded in a half area of the frame structure, and the other half of the area is a hollow area, as shown in fig. 2A or 2B; alternatively, the central region of the frame structure is a hollow region, and a single-sided mirror is embedded around the peripheral region, as shown in fig. 2C or 2D.

In the present application, the camera module 300 includes, but is not limited to: an optical filter 310, an image sensor 320, an analog-to-digital converter 330, and an image processor 340; wherein the image sensor 320 is a CCD type or a CMOS type.

For example, as shown in fig. 3 or fig. 4, during shooting, light from the object to be shot enters from the outer lens 100, is reflected by the transmission and reflection assembly 200 (here, a lens is taken as an example), passes through the optical filter 310, and is projected to the image sensor 320 to generate an analog signal, passes through the a/D adc 330, and is converted into a digital signal, and then passes through the image processor 340 to store or subsequently process the data, thereby completing the shooting process.

In fig. 3 or fig. 4, the transflective assembly 200 employs a lens that reflects light from one side and transmits light from the other side, but it should be understood that the transflective assembly 200 is also applicable to a single-sided mirror or a frame structure, and is not limited to a lens, but a schematic structural diagram of the camera assembly 300 or the projection assembly 400 is shown with emphasis on the lens as an example. For convenience of description, the combination structure of the single-sided mirror or the frame structure, the image capturing module 300 and the projection module 400 is not shown in the corresponding schematic diagram. But will be apparent to those skilled in the art from the description of the second and third embodiments of the present application. The following embodiments are also applicable, and will not be described in detail.

The CMOS is an abbreviation for Complementary Metal Oxide Semiconductor (CMOS). The CMOS type image sensor has the advantages of good radiation resistance, high system reliability, random window reading capability, low cost and the like.

In the present application, the types of the projection assembly 400 include: single DLP, multiple DLP, 3LCD, and LCOS.

The DLP is an abbreviation of Digital Light Processing, i.e. firstly digitally Processing the image signal and then projecting the Light, which is one of the common projection types.

As shown in fig. 3, in the present application, the single DLP type projection assembly 400 includes: a light source 410, a condenser lens 420, an RGB color wheel 430, a trim lens 440, and a DMD chip 450.

For example, during projection, light generated by the light source 410 passes through the converging lens 420, is projected onto the RGB color wheel 430, is separated into red light, green light and blue light, passes through the trimming lens 440, and is projected onto the DMD chip 450, and the DMD chip 450 receives and processes a video signal, reflects a corresponding image, transmits through the transmission/reflection assembly 200 (taking a lens as an example here), and then passes through the outer lens 100, and is projected, thereby completing a projection function.

For example, in the projection, the light generated by the light source 410 passes through the first reflector 471, transmits red light, and reflects a green-blue mixed light; the green-blue mixed light passes through the second reflecting mirror 472 to reflect green light and transmit blue light; red light, green light and blue light are respectively projected and transmitted through respective LCDs, and the LCDs receive and process video signals to project corresponding three-color images; the three-color image projects a color image through the light-collecting prism 490; after transmitting through the transmission/reflection assembly 200 (here, taking a lens as an example), the image light passes through the outer lens 100 and is projected out, thereby completing the projection function.

In the present application, a focusing system is disposed in the outer lens 100, so that the camera module 300 and the projection module 400 share the focusing system; alternatively, a main focusing system is disposed in the outer lens 100, and a sub focusing system is disposed in the image capturing module 300 and/or the projection module 400, respectively.

For example, the outer lens 100 may or may not include an auto-focus system, and may be optionally configured as desired. The camera module 300 and the projection module 400 may also share a set of focusing system of the outer lens 100. For example, the same set of auto-focus systems may be shared between the DMD chip of the projection module 400 and the image sensor of the camera module 300 when the respective sizes are proportional to the distance of the outer lens 100, the image size and the projected distance.

In addition, according to the requirement of practical application, a set of focusing system is arranged in the outer lens 100, and a set of focusing system can be arranged in the camera module 300 or the projection module 400, wherein one is mainly arranged and the other is auxiliary arranged, so that the focusing precision and flexibility can be further improved.

the control chip 500 is shared by the camera module 300 and the projection module 400; or, the control chip 500 is independent, and the camera module 300 and the projection module 400 are electrically connected to one control chip 500 respectively, so that the camera module 300 and the projection module 400 can be used independently.

As shown in fig. 3 or fig. 4, the control chip 500 is integrated, that is, the image capturing module 300 and the projection module 400 are shared, and are driven and controlled by the same set of control chip 500, and for saving space and cost and improving efficiency, the control chip 500 is preferably integrated into a set of system integrated control.

In this application, when the control chip 500 is integrated, the control chip 500 is further configured to perform interactive processing on the image data acquired by the camera module 300 and the image data projected by the projection module 400.

The content of the camera shooting and projection in the camera shooting and projection all-in-one machine can be interactive or non-interactive. For example, one scenario of interaction is: the image or video content obtained by the camera module 300 is processed in real time by the integrated machine and then projected by the projection module 400. If, gather face information through subassembly 300 of making a video recording, then add the makeup information through the corresponding face information of all-in-one, then carry out the projection through projection subassembly 400 again to improve greatly and make a video recording and the organic deep integration between the projection function.
