Embodiment
Consult shown in Figure 1, specific embodiment for single-sensor paralleling type stereoscopic picture shooting device of the present invention, comprise CCD or cmos sensor 1, sensor 1 connects image processor 6, sensor 1 adopts 4:3 general format in the prior art, and sensor 1 is to differ the setting of an angle of 90 degrees direction with the normal mounting position; Being provided with axial line distance in sensor 1 front portion is two groups of optical imaging lens groups 2 of 25～100mm, preferable axial line distance between two groups of optical imaging lens groups 2 is 57～65mm, the inboard of every group of optical imaging lens group 2 is equipped with first catoptron 3, second catoptron 4 and optical path direction transition components 5, and the two ways of optical signals with sight equation is being incident upon the left and right sides imaging of sensor 1 respectively respectively behind optical imaging lens group 2, first catoptron 3, second catoptron 4 and optical path direction transition components 5; , optical path direction transition components 5 can adopt the prism group, and left and right two groups of prism groups can be to be rotated counterclockwise two ways of optical signals 90 degree respectively.
Consult shown in Figure 2, the present invention is owing to adopt the CCD or the CMOS of traditional 4:3 standard format, when the sensor 1 that utilizes 4:3 obtains the stereo-picture of 16:9, for making full use of the pel array of sensor 1, left and right double light path will directly throw the image of upper and lower stack on sensor 1, this has suitable difficulty in optical design, cause complex structure, also is not easy to realize; So, the present invention is a simplified structure, imageing sensor 1 is spent to being rotated counterclockwise 90, simultaneously, the imagery exploitation prism that each light path forms etc. also is rotated counterclockwise 90 degree, makes image that left and right two light paths form drop on the and arranged on left and right sides at the center of double light path to revolve the mode that turn 90 degrees, image imaging at CCD or cmos sensor 1 with axisymmetric both sides, center, form SIDE BY SIDE, do not produce intersection during for the assurance imaging, choosing of image then is according to the M of getting x N shown in Figure 2.Respectively stay on the Width of image near 5% the room D that accounts for picture traverse.
Consult shown in Figure 1ly, stereoscopic picture shooting method of the present invention comprises subordinate's step:
(1) scenery light to be taken focuses on by two groups of optical imaging lens groups of axial line distance 25～100mm, forms the left and right two groups of light signals with sight equation.
(2) focus on two groups of light signals being obtained respectively through first catoptron and second catoptron, two secondary reflections with sight equation.
(3) left and right two groups of light signals are respectively through making light signal be rotated counterclockwise the optical path direction transition components (prism group) of 90 degree.
(4) two groups of light signals are incident upon by being rotated counterclockwise 90 spends on the CCD or cmos sensor of the 4:3 that is provided with, forms left and right two and forms picture.
(5) the left and right two picture group image signals of CCD or cmos sensor are stored after Flame Image Process.
Consult shown in Figure 3ly, behind the image imaging of the present invention, carry out image by data reading circuit according to certain frame rate and read; The view data that reads comprises the image that two width of cloth form simultaneously, through FIFO left and right picture data is separated then; Image after the separation is the full frame image that two width of cloth are obtained simultaneously, after this view data enters the picture format treatment circuit, can directly generate SIDE BY SIDE image, also can generate FRAME BY FRAME, FIELD BY FIELD, LINE BYE LINE, DOT BY DOT or the like format-pattern.
Carry out as requested entering into scrambler after the format conversion at image, audio frequency and video are carried out synchronous compressed encoding here and are handled; Data behind the coding enter storer and preserve; If watch the image that has stored, then need from storer, to access data, after relevant coding and driving are delivered in the process decoding then again, be used to output to external display, perhaps watch with the binocular that carries in the machine or single stereoscopic display screen.
Consult shown in Figure 3ly, the present invention has increased an audio frequency and video change-over switch, and its effect is: image is through separating the back by picture format processor output SIDE BY SIDE signal; When picture pick-up device in the production process and need to monitor when shooting with video-corder picture, this signal will directly be delivered in the machine monocular or single stereoscopic display screen shows that audio frequency also switches to real-time audio simultaneously by the audio frequency and video change-over switch; When monitoring image, the action delay of picture and actual scenery is less like this, is convenient to timely monitoring, can realize straight-through function substantially.When playback during recorded program, the audio frequency and video change-over switch switches to the demoder output terminal with signal, so just can enjoy the fragment that records.
When taking stereotome, the present invention can obtain the complete picture that left and right picture does not have time-delay, other modes of comparing, and left and right nothing time-delay, the picture video format change that the present invention represented is many, the advantages such as quality high unity of picture.
