Abstract

The utility model discloses an image pickup device with a projection function, which comprises a projection unit for projecting the image, a shooting unit for picking up the external scene, a processing unit that is used for receiving the image that is taken by the shooting unit and conveys the image to the projection unit after the image is processed, and a control unit that is used for controlling the projection unit, the shooting unit and the processing unit, wherein, the shooting unit shares the same fixed optical element with the projection unit. The image pickup device that is provided with the projection function not only can realizes the projection function and the shooting function respectively, but also can project the image that is shot by the shooting unit through the projection unit, so as to be watched by people. The device is only provided with one fixed optical element, thereby simplifying the structure of the device, and narrowing the volume of the device, and favoring the carrying and the outdoor application.

Description

Picture pick-up device with projecting function

Technical field

The utility model relates to a kind of picture pick-up device, relates in particular to a kind of picture pick-up device with projecting function.

Background technology

In the prior art, digital camera usability optical device, the image of picked-up is recorded in the storage medium after changing electric signal into, after the picked-up image, utilize the LCD screen show image on the camera, thus convenient with clapping, still because the restriction of screen size with seeing, the size of image has limitation, and the same time only can be fit to single or a few user watches image on camera; And image projecting is gone out by projector in the prior art, share simultaneously for everybody, but its volume is very big, is not suitable for carrying, and mainly uses in indoor place at present.If can get both chiefs in conjunction with the characteristics of digital camera and projector, then can solve above mentioned shortcoming, this also becomes the emphasis of industry research and development.At present, this equipment that can realize both functions that relevant patent disclosure arranged, a kind of camera head that projector is installed is disclosed as Chinese patent 200710185142.X, it comprises the image pickup optical system of being made up of a plurality of lens, imaging apparatus, projector portion, travel mechanism and at least one piece of dual-purpose lens, this device by travel mechanism with at least one piece of dual-purpose lens configuration any one position in the primary importance and the second place, this primary importance is disposed on the optical axis of image pickup optical system, and this second place is disposed on the optical axis of projecting lens unit.Though it has realized photograph and two kinds of functions of projection, it has projection, shooting two cover optical systems and will use travel mechanism the dual-purpose lens to be configured in respectively on the optical axis of two optical systems, complex structure, and volume is bigger, is inconvenient to carry and use.

The utility model content

The purpose of this utility model just provides a kind of picture pick-up device with projecting function simple in structure, portable, and it both can realize projection and the function of taking pictures respectively, the image projecting that image unit absorbed can be gone out again.

For achieving the above object, the picture pick-up device that the utlity model has projecting function adopts following technical scheme:

A kind of picture pick-up device with projecting function, comprise to projection image carry out projection projecting cell, be used to absorb outside scene image unit, be used to receive the image of described image unit picked-up and handle after pass to the processing unit of described projecting cell and be used to control the control module of described projecting cell, image unit and processing unit work, the shared fixing optical device of described image unit and described projecting cell.

Further, the shared camera lens of described image unit and described projecting cell.

Further, described projecting cell comprises light source, reflective LCD element, the optical device shared with image unit, the camera lens shared with image unit.

Further, described image unit comprises solid-state imager, the optical device shared with projecting cell, the camera lens shared with projecting cell.

Further, also be provided with an interface that is connected with the foreign medium memory device.

The beneficial effects of the utility model just are: image unit and projecting cell can be realized separately respectively taking pictures and the function of projection, projecting cell be handled and be passed to processing unit can also with the image that image unit absorbed, projecting cell is gone out the image projecting that receives again, especially the shared fixing optical device of projecting cell and image unit in this equipment, simplified the structure of machine itself, make its volume less, be convenient for carrying and outdoor use, this equipment only is provided with a camera lens in addition, has further simplified its structure.

Describe the picture pick-up device that the utlity model has projecting function in detail below in conjunction with accompanying drawing, it is as the part of this instructions, by embodiment principle of the present utility model is described, other aspects of the present utility model, feature and advantage thereof will become very clear by this detailed description.

Description of drawings

Fig. 1 is the synoptic diagram of a preferred embodiment that the utlity model has the picture pick-up device of projecting function.

Embodiment

Embodiment of the present utility model now is described in conjunction with the accompanying drawings.

Fig. 1 is the synoptic diagram of a preferred embodiment that the utlity model has the picture pick-up device of projecting function.As shown in Figure 1, the picture pick-up device that the utlity model has projecting function comprises projecting cell 1, image unit 2 receives image unit 2 photographic images and its processing is passed to the processing unit 3 of projecting cell 1, controls the control module 4 and a shell 5 of each cell operation.Projecting cell 1 comprises led light source 11, LCOS (Liquid Crystal on Silicon reflective LCD element) 12, optical device 13 and camera lens 14.Image unit 2 comprises the camera lens 14 shared with projecting cell 1, optical device 13 and the solid-state imager 21 shared with projecting cell 1, wherein optical device 13 can be the combination of a plurality of optical elements, it also can be single optical element through special processing, the solid-state imager of Shi Yonging is CCD (a ChargeCoupled Device charge-coupled image sensor) in the present embodiment, also can be CMOS (Complementary Metal Oxide Semiconductor CMOS (Complementary Metal Oxide Semiconductor)) etc. in other embodiment of the utility model.In addition, this equipment also is provided with the interface 6 that connects external unit.When the picture pick-up device with projecting function shown in the present embodiment connects external memory storage by interface 6, need be when image projection be come out in the external memory storage, control module 4 is controlled only projecting cell 1 work, and the image projection in the described external memory storage is come out; When needs were taken a picture, control module 4 was controlled only image unit 2 work, absorbs outside scene; When after needs are taken pictures, institute bat image projecting being come out, the described projecting cell 1 of control module 4 controls, camera unit 2 and processing unit 3 are all worked, camera unit 2 absorbs outside scenes and the signal of taking in is passed to processing unit 3, processing unit 3 is with received signal Processing, change into the form of projecting cell 1 needs and pass to projecting cell 1, projecting cell 1 projects these scenes again.
