＜device constitutes 2 〉
Fig. 3 is the motion of expression according to the image of projection in the display frame 21 of judging object display 2, judges the skeleton diagram of structure of motion picture processing device 1a of the movement display performance of this judgement object display 2.Fig. 4 is the side view that the position relation of object display 2 and electric camera 3a is judged in expression.
Motion picture processing device 1a possesses: the electric camera 3a of the display frame 21 of the judgement object display 2 of shooting stable state formula; Be used for obtaining the computer control portion 4 of moving image response curve according to the shooting picture of electric camera 3a; To the picture signal generator 5 of judging the motion image signal that is provided for showing the moving image that the speed with regulation moves on the object display 2.
In the example of Fig. 1, as being 100% (in vain) judging that " moving image " that show on the object display 2 uses left-half brightness, the brightness of right half part is the step-like image of 0% (deceiving).The part that the brightness of central authorities is switched is called " edge ".The moving image hypothesis moves in display frame 21 from left to right.Judge that display frame 21 usefulness of object display 2 have mask 6 coverings of horizontal gap.
By the rotation of this galvanic reflex mirror 35, the visual field of camera can be with last mobile at the vertical direction of the moving direction of moving image (above-below direction) S in display frame 21.In the time that move in display frame 21 from bottom to top in the visual field of this camera, the edge of moving image is vacillated moving from left-hand in the display frame 21 of judging object display 2.That is, the edge of moving image time of moving from left to right was comprised in the time of the visual field of camera moving from bottom to top in display frame 21.The rotating drive signal of this galvanic reflex mirror 35 is provided by galvanic reflex mirror driving governor from computer control portion 4.And, can not constitute galvanic reflex mirror 35 and camera body 34 respectively, the camera body of light weight digital camera etc. is arranged on the turntable, carry out rotating drive with rotational drive motor.
1 time for exposure (opening the time of shutter) of camera body 34 is compared identical with the sweep time of 1 frame of judging object display 2 or is longer than it.1 time for exposure of camera body 34 is write " n " with the ratio of the sweep time of 1 frame of judgement object display 2.For example, with respect to the situation that sweep time of 1 frame of judging object display 2 is 1/60 second, the time for exposure of camera body 34 is the time of judging the n frame sign (n/60 second) of object display 2.
At this, " n " it is desirable to if possible then it is desirable to more than or equal to 3 more than or equal to 1.If be set to " more than or equal to 1 ", then, can in fact picture signal be carried out time integral drawing of 1 frame more than the time, so can get rid of the noise of single-shot because on the two-dimensional CCD array.Being set to " it is desirable to more than or equal to 3 " is because if the time for exposure is 3 frames, and then under the nonsynchronous situation of beginning of exposure beginning and frame, the frame before and after casting out is put into cause in the two-dimentional ccd array fully with 1 frame of center.Because " n " if the upper limit can measure from the time that the end to end of picture moves at moving image, so in its traveling time, obtain.Because in the translational speed of moving image, can set various speed, thus can not express the upper limit, but it is general, because be converged in the time for exposure of the maximum of can enough camera bodies 34 setting, so no problem.
The picture signal that obtains with camera body 34 is taken into the I/O port by image and is taken into computer control portion 4.
Fig. 5 (a)～Fig. 5 (d) is the figure that is illustrated in the passage of time of the image of breaking forth on the two-dimensional CCD array of camera body 34.
Rotate during 1 time at galvanic reflex mirror 35, the edge of moving image moves from left to right.The ccd array of 34 pairs of two dimensions of the camera body shooting that exposes during this period.Like this, on the two-dimensional CCD array, accumulate picture signal.The display frame 21 of judging object display 2 is as mentioned above because use the mask 6 in the slit with level to hide, so obtain Fig. 5 (a)～such moving image of Fig. 5 (d) by this slit.The moving image that obtains on the two-dimensional CCD array becomes the image of accumulating the capable shape of level according to time sequencing.
＜parsing order 〉
Following parsing order is shared in motion picture processing device 1,1a.
The program of the computer executive logging of following parsing order by motion picture processing device 1,1a on the medium that is arranged at regulations such as CD-ROM on motion picture processing device 1, the 1a and hard disk realizes.
Expression is pixel with the transverse axis, is the time with the longitudinal axis in Fig. 6, and to carrying out patterned situation with linear array camera 3 or the detected luminance signal of electric camera 3a, Fig. 7 represents the photo of shooting when this graphical display is on computer picture.
Among the figure, " Tf " is 1 vertical interval of judging object display 2.Judge that object display 2 is stable state formulas, moving image stops in 1 sweep time Tf.V is the displacement of the moving image between consecutive frame.In this sweep time Tf, 3 exposures of linear array camera are (drawn 4 times, and be actually about 100 times) for several times in Fig. 6, and perhaps galvanic reflex mirror 35 rotates the electric during this time camera 3a exposure of a circle for several times.Each row of the level that obtains by each exposure with " DL " expression.Such shown in the enlarged drawing of Fig. 6,1 row is that R (red), G (green), 3 kinds of pixel repeated arrangement of B (orchid) form, detection signal also becomes the luminance signal that R, G, B3 kind signal replace continuous serial, but the processing by the built-in control part of camera (not shown) is transformed to parallel signal, can export the train of signal of R, the train of signal of G, the train of signal of B discretely.Like this, even monochromatic linear array camera 3 and monochromatic electric camera 3a also can obtain the response curve of each pixel of R, G, the B of display.
Below in Fig. 6, fix the display pixel of 1 camera, obtain the luminance signal string of each time.This operational example is as being identical with the situation that obtains signal along the A-A section of Fig. 6.
Fig. 8 is the figure of effluxion of luminance signal that is illustrated in each color of this pixel of formation under the situation of the display pixel of fixing 1 camera.
Can access the response curve of a pixel paying close attention to camera with this figure.The brightness of each color is moved according to the edge in the display frame 21 of judging object display 2, together rises with the time, and can know the response time of each pixel of RGB according to the shape of this rising.At this, so-called response time is meant that brightness rose to for 90% needed time from 10% value of maximum gray scale.In the example of Fig. 8, the response time measured value of R pixel, G pixel, B pixel is R pixel=45.26msec, G pixel=44.80msec, B pixel=43.24msec.The poor of 2msec of having an appointment between R pixel and B pixel under the situation that visually sees the display frame 21 of judging object display 2, known often to be off color on the edge of moving image.
Like this, by catching changing in a certain pixel of camera, can access the moving image response curve of each pixel of RGB in the time of judging the moving image that shows on the object display.
Below, illustrate order with the moving image response curve of each pixel of RGB that obtains Fig. 8 different, be conceived to other the order that tracking direction (smooth pursuittracking) at the eyes of moving image is asked the moving image response curve.
Fig. 9 is to be pixel with the transverse axis, is the photo (photo the same with Fig. 7) in the time of the time will being presented on the computer picture 7 with the detected luminance signal of camera with the longitudinal axis.At this, " white circle " is illustrated in the position at the edge of the moving image that occurs in 1 frame scan.
When the people sees moving image, suppose eyes are moved smoothly.That is, the tracking direction of eyes is thought and is moved along the edge of moving image.On the time and space of Fig. 9, with the direction indication of the tracking direction of this people's eyes a series of with linking " white circle ".If this direction is set to θ,
Then become θ=tan
-1(displacement of the moving image in 1 frame v)/(the demonstration interval T f of the display in 1 frame).
Try integration is carried out in the demonstration of 1 frame amount along the tracking direction of these eyes.
At first, the tracking direction with eyes upward carries out coordinate transform for being taken at same axle.Figure 10 (a), Figure 10 (b) are the diagrams of the method for denotation coordination conversion.Figure 10 (a) is the same with Fig. 9, represents to represent with transverse axis the display position of linear array camera 3, with the orthogonal coordinate system of longitudinal axis express time.Allow it move (amount of movement is along with the time is traced back to over just many more more) abreast, the tracking direction of eyes becomes transverse axis.Coordinate system after Figure 10 (b) expression conversion.The bearing mark of the longitudinal axis in the coordinate system after the conversion is " y ", with the bearing mark of its quadrature be " x ".The direction of " display position " axle is parallel before x direction and the conversion.With the luminance signal in the coordinate system after this conversion be designated as G (x, y).
Figure 11 (a), Figure 11 (b) are the figure that expression is carried out coordinate transform to image shown in Figure 9.Figure 11 (a) is the image of the photo before the conversion, and Figure 11 (b) is the image of the photo after the conversion.The tracking direction of eyes is along the y axle.Because " display position " before x axle and conversion axle is an equidirectional, so can the conversion imaging prime number.
At this, with luminance signal G (x, y) the integral multiple that is equivalent to 1 frame apart from upper integral.If the luminance signal behind the integration is designated as G (x), then becomes following formula.
G(x)＝∫G(x，y)dy
Limit of integration is at " integral multiple of 1 frame ", is that white circle is enclosed in white among Figure 11 (b).In Figure 11 (b),, draw the limit of integration of " 1 frame 1 times " as the example of limit of integration.
Figure 12 gets 1 frame amount with limit of integration, and the luminance signal G (x) that will try to achieve by integration is that transverse axis carries out patterned figure with the x axle that is scaled pixel count.This Figure 12 becomes the moving image response curve.This moving image response curve and people's eyes are followed the tracks of smoothly on one side and are observed the situation of the moving image of showing out in display frame identical on one side.
From the moving image response curve of this Figure 12, can calculate moving image response time, motion image blurring time, blurred width etc.
If X-axis is arranged to the pixel count of display, then blurred width is the pixel count that is included on 10%～90% the interval of output waveform.Under the situation of Figure 12, fuzzy width becomes about 10 pixels.
The motion image blurring time multiply by " (pixel count/moving image frame of display moves pixel count) * 1 frame time " by the X-axis with Figure 12 and transforms on the time shaft and try to achieve.In this case, the motion image blurring time becomes the time in 10%～90% the interval that is equivalent to output waveform.
