1. Field of Invention
The present invention relates to an apparatus for moving stereo imaging lens and a method for digital stereo projection.
2. Description of Related Arts
Nowadays, most enlarging-printing devices for digital pictures are for planar photos. There is still blank in developing devices for digital stereopicture in the market. Even the few digital stereopictures in the market are imitated stereopictures which are processed with digital stereopicture software, output by the printer and then combined with the grating. This kind of digital stereopictures have not been widely accepted by people or popularized due to high technical requirement, complicated operation, time and work consuming, and overcolored pictures produced.
A technical problem to be solved by the present invention is to overcome the drawback in the prior art that a developing device for digital stereopicture is lacked and lenses move inconveniently when stereo projection, and provide an apparatus for moving stereo imaging lens and a method for digital stereo projection.
In order to solve the technical problem, the present invention provides:
An apparatus for moving a stereo imaging lens, which is characterized in, comprising:
a vertical baseplate;
a LCD displayer for display an image source, wherein a display surface of the LCD displayer is downwardly embedded into a fixing board horizontally mounted on the baseplate;
a light source device mounted on the fixing board and above the LCD displayer; and
a lens positioned under the LCD displayer, wherein the lens is embedded into a lens fixing board mounted slidably and horizontally on the baseplate via a sliding device.
Preferably, the light source device comprises a light mixing canister perpendicularly mounted on the fixing board and a light source element positioned on an upper end of the light mixing canister, wherein the LCD displayer is positioned right under the light mixing canister, two ends of the light mixing canister are respectively closed by the light source element and an upper surface of the fixing board.
Preferably, the sliding device comprises a sliding board having an upper end connected with the lens, a sliding block is fixedly mounted on a side of the sliding board opposite to the baseboard, a guide screw adapted to the sliding block is mounted horizontally on the baseplate, an end of the guide screw is connected with an output end of an electromotor.
Preferably, a sliding rail parallel to the guide screw is mounted on the baseplate and aside the guide screw, a convex portion adapted to the sliding rail is provided at a position corresponding to the sliding rail on the sliding board.
Preferably, at least a protuberance is mounted on a side of the lens fixing board opposite to the sliding board, a vertical rail adapted to the protuberance is provided on the sliding board.
The present invention further provides a method for digital stereo projection with the apparatus for moving a stereo imaging lens, which is characterized in, comprising the following steps:
S1: displaying a first photo with the LCD displayer, wherein the lens is under the LCD displayer, and turning on the light source device to process a first projection and sensitization;
S2: switching to a second photo by a computer, the lens moves for a certain distance in a horizontal plane from a previous position, moving a sensitization platform synchronously along a direction the lens moves, until a light cast through the lens covers the whole surface of a photosensitive material again;
S3: tuning on the light source device to process a second projection and sensitization to the photosensitive material; and
S4: repeating the steps S2 and S3, until all photos are processed for projection and sensitization.
Preferably, the method further comprises a step of: taking photos of a same scene from different views before the step S1.
Preferably, the direction the lens moves is a rotating direction of a camera when taking a photo for a present projection and sensitization process with respect to the camera when taking a photo for a previous projection and sensitization process.
Preferably, the method further comprises a step of: developing the photosensitive material after the step S4.
The positive beneficial effect of the present invention is as follows. The apparatus for moving a stereo imaging lens has simple structure, convenient operation, is capable of moving for projection and sensitization for multiple times. In addition, the LCD displayer is adopted to be the display device, so that the image source obtained by digital devices can be processed for stereopictures, and thus has high sensitization accuracy. Furthermore, the focus of the lens according to the present invention can be adjusted by the rail in vertical direction, so as to change the image size, and increase the image effect and size of the stereopictures.
A preferred embodiment of the present invention is described by accompanied with the drawing.
Referring to
Referring to
Preferably, the lens fixing board 10 is slidably provided on the sliding board 7, and has a protuberance, and the sliding board 7 has a vertical sliding rail 9 adapted to the protuberance. During projection and sensitization, the lens fixing board 10 is adjusted to change a focus of the lens 5.
A method for digital stereo projection with the above apparatus for moving a stereo imaging lens is further described below.
Firstly, to describe more clearly, three photos to be used is described herein. A first photo is taken by a camera in front of an object, a second photo is taken by the camera after turning left around the object for 5 degrees from the front thereof, and a third photo is taken by the camera after turning right around the object for 5 degrees from the front thereof.
Secondly, the left or right direction is based on the front of the object.
S1: displaying the first photo with the LCD displayer 15, wherein the lens 5 is right under the LCD displayer 15, when three-colored light cast by the light source device 4 reaches to the lens 5 via the LCD displayer 15 after being mixed by the light mixing canister 2, the first photo on the LCD displayer 15 is processed for projection and sensitization on a photosensitive material 18 through the lens 5 and a grating 17, to finish a first projection and sensitization;
S2: switching to the second photo by the computer, the electromotor 12 drives the lens 5 to move leftwardly and horizontally for a certain distance, wherein a sensitization platform 16 synchronously moves along a direction the lens 5 moves, until a light cast through the lens 5 covers the whole area of the photosensitive material 18 again;
S3: processing a second projection and sensitization to the photosensitive material 18, which is same to the step S1;
S4: switching to the third photo by the computer, the electromotor 12 drives the lens 5 to move rightwardly and horizontally for a certain distance, wherein the sensitization platform 16 synchronously moves along a direction the lens 5 moves, until a light cast through the lens 5 covers the whole area of the photosensitive material 18 again;
S5: processing a third projection and sensitization to the photosensitive material 18, which is same to the step S1; and
S6: developing the photosensitive material 18.
It is worth mentioning that, a projection and sensitization order of photos of different views can be changed freely, not limit to the above preferred embodiment.
One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.
It will thus be seen that the objects of the present invention have been fully and effectively accomplished. Its embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
