 The present invention relates to a processing apparatus for television pictures and, more particularly, to color television pictures.

 With the recent increase in the type of television programs, a demand has appeared for a device for mass reproduction of television images desired by photography of these images or their transcription by printing. Until now, to reproduce a television image in mass production, it was common practice to photograph the television image with, for example, a photographic camera to obtain a color photograph, to make a snapshot from the color photography using a processing machine and to mass-reproduce the television picture with the help of this shot.However, the television picture reproduced on the television pictureimage in colors usually have color temperatures of about 9000K and this results in a radiation of the three different fluorescences, namely the red fluorescence (R), the green fluorescence (G) and the blue fluorescence (B). As a result, the spectral energy distribution of the image does not coincide with the spectral sensitivity distribution of the photosensitive emulsion, so that a color photograph obtained by simply transforming into colors by a photograph of colors the color temperatures of the television picture displayed on the picture tube does not have a satisfactory quality although it may appear suitable to the eye.Moreover, the television picture is formed by 525 lines of scanning, regardless of its dimensions, and its resolution is lower than the images generally processed. Furthermore, because the snapshot is taken after the television image has been photographed by color photography, the television image in its printed form is considerably deteriorated as far as the resolution, the tone of the image is concerned. its colors, gradation, etc.

 The object of the present invention is to provide a color television image processing apparatus, which apparatus does not deteriorate the resolution, color tone, gradation, etc. of the television picture.

 It is also an object of the present invention to provide a color television image processing apparatus in which the reading or extraction of the video signal is controlled in synchronism with the rotation of the color image scanning analyzer so as to enable the use of a commercially available scanning analyzer.

 It is also an object of the present invention to provide a processing apparatus which eliminates the need for the correspondence relationship between the horizontal scan lines of the television picture and the scan lines of the color image analyzer and allows as a result, the video signal of the television image is processed in accordance with the rotation of the commercially available scanning analyzer by adopting a perpendicular relationship between the horizontal scan lines of the TV picture and direction of exposure scan lines in the scanning color image analyzer.

 Another subject of the present invention is a processing apparatus which can compensate for the deterioration of the quality of the printing image, which deterioration can occur with the conventional frame images when, from a tram another frame image by interpolation of the average values.

 Still another object of the present invention is to provide a processing apparatus that allows precise selection of the specified television image from the video image recorded on a video tape.

 An embodiment of the present invention will now be described with reference to FIG. In this figure, it can be seen that a television signal of the NTSC system is applied to a video recorder 11. As a video recorder, a 25.4 mm or 50.8 mm tape recorder is used for commercial writing. In order to select a television image as an original intended for the production of photographs, the video recorder must preferably be able to perform a restitution or slow visualization and a rendition or fixed display. A television picture number generator 12 and a read television picture number indicator 13 are connected to the video tape recorder 11. The output side of the video recorder 11 is connected to a control television 14 and a memory 15. television image The television picture memory 15 is adapted for a signal of a television picture to be recorded therein and read in response to a write or read command signal from a generator 16 of write / read control signals. The write / read control signal generator 16 outputs a write control signal in synchronism with a timing signal from a television sync signal generator 17 and outputs a playback control signal in synchronism with a frequency dividing output signal of a frequency divider 18 which divides by n (n being an integer) the synchronization signal from the synchronization signal generator 17. The read signal, i.e. extracted 1 from the image memory 15 is applied to a switching circuit 19.

The switching circuit 19 is controlled by an adjustment signal generated by an adjustment signal generator 20 in synchronism with the frequency division signal of the frequency divider 18. In the switching circuit 19, the television image is adjusted in a desired manner and a video signal corresponding to the adjusted image is emitted by the switching circuit 19. The output of the switching circuit 19 is applied to a control television 21 as well as to a switching circuit 22 The switching circuit 22 exchanges the signals of the odd and even fields of an image which are applied thereto via the switching circuit 19 in response to a control signal of a logic circuit 23. The switching circuit 22 comprises an even frame output terminal connected to an even frame Ie memory 24 and an odd field output terminal connected to an odd field memory 1E 26.

The writing and reading of the memories 24 and 26 are performed in response to control signals of a write / read control signal generator 27. The write / read control signal generator 27 outputs control signals in response to the output signal of the logic circuit 23, and the rate or rate of the readout can be adjusted using a dispo
The output signals of the memories 24 and 26 are applied to an NTSC decoder 29 which
has the function of transforming the frame signals of the memories
24 and 26 into three primary color signals, i.e.
D signals R (red), G (green) and B (blue). The output signal of the NTSC decoder is applied to a converter 30 which trans
form the R, G, and B signals into print signals, i.e.
say in Y (yellow), M (magenta), C (cyan) and BK (black) signals.

The output signal of the converter 30 is applied by
via a correction circuit 31, to an analyzer
32 scanning for color images. The analyzer 32 is
operated in synchronism with the frequency division signal
of the frequency divider 18.

We will now describe, referring to the circuit of the
FIG. 1, the operation of the apparatus used to prepare
television image printing snapshots according to the present invention. An NTSC television signal is applied
to VCR 11 and is recorded therein. At this moment, information which, for each image, is relative to the number of the image
and is applied from the image number generator 12
is also registered. it is possible just as well
to record this image number information on a track
audio which is not used for other purposes When a desired image is extracted from the video recorder 11 in which are recorded
the television signals, the number of the desired image
is established by the image number indicator 13 and the magnetos
cope It is placed in a state of signal restitution. The
The signal reproduced by the video tape recorder 11 is applied to a control television set 14 for reproduction. At the time
of this signal restitution, the image number information
is extracted from the video recorder 11 and is compared with the infor
pre-established image number. Or a video signal
of television image corresponding to the image information
pre-established is extracted, the generator 16 of control signals
write / read function sends a write command signal, in
as a write instruction, to the image memory. I1
result that the image video signal corresponding to the number
pre-established image is written in the image memory. The
the image memory may be an analog type magnetic disk memory or a digital type solid state memory and in the present embodiment a magnetic disk memory is used. In this magnetic disk memory, the video signal is stored in such a manner as that shown in Fig. 2. A television image comprises 525 horizontal scanning lines constituting an odd field and an even field. A television image also includes vertical blanking periods corresponding to lines 1 to 20 and 264 to 283 with horizontal sync signals (not shown) disposed between adjacent lines (Fig. 3). As can be seen in FIGS. 2 and 4, the odd field comprises lines 21 to 263 and the even field comprises lines 283 to 525.

 When the video signal is extracted from the disk magnetic memory 15 shown in FIG. 2, the lines belonging to the even and odd fields are alternately extracted, as shown in FIG. 4, for example the first line 283 in the even frame, then the line 21 in the odd field, then the line 284 in the even field and so on. During this extraction or reading, the magnetic disk memory rotates at a constant speed and the video signals for the individual lines are transmitted in the aforementioned order by a magnetic head (not shown). The reading of the signal in the above order is obtained by an on / off control of the switching circuit 22 by means of a control signal from the logic circuit 23.The switching circuit 22 applies the video signal of even frame to the frame pair memory 1H 24 and the odd frame video signal to the odd frame 1H memory 26.

(secondes)
La période R qui peut être utilisée pour la lecture est 0 < R < A-W. FIG. 5 shows the write and read rates for the memories 24 and 26. To extract an image signal from the memories 24 and 26, it is necessary to determine the write and read rates, taking into account the periods exposure in the scanning analyzer. While the exposure period in the scanning analyzer is determined by the sensitivity of the film or film on the scanner drum and by the intensity of the light, this period is longer than that required to scan. , ie explore, the television signal obtained. Therefore, it is necessary to read the video signal over a period of time which is several times that of the scanning period. The playback period can be appropriately adjusted by adjusting the frequency divider ratio of the divider. frequency 18 on an appropriate value. In the present embodiment, the write and read periods are set by adjusting the frequency division ratio n as shown below. The W period of writing in memories 24 and 26 is
W = x-525 xn (seconds)
30
The maximum period A, which can be used by the memories, is

(Seconds)
The period R that can be used for reading is 0 <R <AW.

As can be seen in Figure 6, a yellow plate (Y), a magenta plate (M), a cyan plate (C) and a black plate (BK) are placed in a row on the cylinder 33 of the scanning analyzer. The direction of the 525 horizontal scanning lines corresponds to a direction Y (ie the direction of rotation). The circumference L of the cylinder 33 is
L = or S is the diameter of the cylinder. If we designate the longitudinal or horizontal dimension of the finished image of clichés by
Y, the reading period R of memories 24 and 26 is
R: Ax Y (seconds)
Where A is the period required for a revolution of the scanning cylinder. The rotational speed of the scanning analyzer cylinder, the reading period and the frequency division ratio are determined to satisfy the equation above. The writing and reading of the memories 24 and 26 are performed according to the control signals transmitted by the generator 27 writewriting control signals at a rate which is previously established in the above manner. The playback period can be set to a desired value by setting the play period regulator device 28. The horizontal line signals alternately extracted from the memories 24 and 26 at the aforementioned rate are applied to the NTSC decoder 29 in order to to be converted into tris primary color signals, i.e. R, G, B signals, which are themselves transformed in the converter 30 into Y, M, C and BK signals necessary for printing. Y, M signals , C and BK are corrected for gradation, color tone, etc., in the correction circuit 31 and are then applied to the scanning analyzer 32.In the scanning analyzer 32, the signals i, M, C and BK are converted into corresponding light intensities for reproduction of the television or frame image in the form of optical images on the Y, M, C and BK plates as shown in FIG. figure 6.

 In the case where, for example, a scanning analyzer manufactured by Dinihon Screen Co. Ltd is used, as a specific example, the frequency division ratio n is suitably equal to 5 (n = 5). ). In this case, the rotational speed of the scanning analyzer is 12 revolutions per second, A is equal to 83.5 milliseconds, W is equal to 317 microseconds, and the exposure period of the film is 41 seconds. . With an analyzer cylinder diameter of 150 mm and a finished image size of 300 mm x 493 nanr, R is equal to 70.9 milliseconds and satisfies the condition o R <A-W.

 As described, in accordance with the present invention, snapshots are taken from a television signal by applying the television signal to a scanning analyzer so that it is possible to produce snapshots without deterioration of the resolution. , the gradation as well as the tone of the colors.

 While the previous embodiment uses two memories for the respective frames, it is also possible to use a single memory as shown in FIG.

In this case, the output signal of the switching circuit 22 is applied to the signal memory 1H, whose output signal is itself applied to the NTSC decoder 29.

 In addition, while in the previous embodiment, the NTSC decoder is placed after the 1H memory, this position is, of course, not limiting; for example, the decoder may be arranged before the image memory and, in this case.

the image memory, the switching circuits 19 and 22 and the memories 1H 24 and 26 may be provided for each of the signals R, G and B.

 In the following embodiments, the NTSC decoder is disposed after the 1H memory.

 The Y dimension of the image of a finished image can be freely adjusted in a range between and (A-W) L / A (mm).

The playback period varies with the dimensions of the image of the shot, but the rotational speed of the cylinder and the exposure period do not change.

 Figures 8A and 8B show a second embodiment.

In this embodiment, the horizontal line signals of the odd and even fields of a television picture which are applied via the switching circuit 19 to the switching circuit 20 pass therethrough alternately and in the order of the numbers. of lines according to a control signal from the logic circuit 23. The output terminal of the switching circuit 22 is connected to a memory 1H 36.

The writing and reading of the memory 36 is performed according to a control signal from a generator 27 of write / read control signals. The write / read control signal generator 27 outputs a control signal as a function of the output of the logic circuit 23 and the read rate is adjusted using the read period adjuster 28. A horizontal line signal written in the memory 36 is read, that is to say extracted, under the control of the control signal generator 27 and is applied to a 1H 37 memory, a generator 38 of intermediate lines and a circuit The line signal applied to the memory -37 to be registered therein is then extracted from it and is applied to an NTSC decoder 29.The distribution circuit 39, the memories 40 and 41, a switching circuit 42 and the generator 38 of horizontal and intermediate line signals are provided to produce an intermediate virtual horizontal line between two adjacent horizontal lines from these adjacent horizontal lines. The horizontal line signal applied to the distribution circuit 39 is inscribed in the memories 40 and 41 alternately, namely, in the present embodiment, the signal of horizontal lines of the odd-frame in the memory 40 and the relative one. to the even frame in the memory 41. The horizontal line signals inscribed in the memories 40 and 41 are chosen by the switching circuit 42 so as to be applied to the generator 38 of intermediate horizontal line signals. The intermediate horizontal line signal generator 38 synthesizes an intermediate virtual horizontal line from the horizontal line signal from the memory 36 and the horizontal line signal from the switching circuit 42. In the present embodiment, the generator 38 intermediate horizontal line signals is adapted to provide an average value of two input line signals.

 The output of the generator 38 of intermediate horizontal line signals is applied to the NTSC decoder 29.

 The horizontal line signal inscribed in the memory 37 is applied to the NTSC decoder 29 under the control of the control signal generator 29 in the manner previously mentioned. Then, an intermediate horizontal line signal between this horizontal line signal and the next (or adjacent) signal synthesized by intermediate horizontal line signal generator 38 is applied to the NTSC decoder 29. Next, the next horizontal line signal stored in the memory 37 is applied to the decoder NTSC 29. In this way, the horizontal line signals and the intermediate horizontal line signals are alternately applied to the NTSC decoder 29.

 In other words, the line 283, the intermediate line between the lines 283 and 21, the line 21, the intermediate line between the lines 21 and 284, the line 284, and so on, are applied in the order mentioned in the NTSC decoder.

In this case, since the number of horizontal lines including the number of intermediate horizontal lines is 1050, the period R that can be used to extract the signal from the memory 36 is O (R <A / 2
When using a scanning analyzer manufactured, for example, by Dainihon Screen Co., Ltd., the frequency division ratio n is suitably 10.

If the frequency division ratio n is equal to 10 (n = 10), the write period W is
w = 1 + 525 xn = 635 (microseconds)
3U 525 and, because
1 = L 263 1 = 83.5 (milliseconds)
A / 2 = 30 = 525 xnx 2 the rotational speed of the cylinder of the scanning analyzer is 1 / 83.5 turn per millisecond, i.e. 718.6 rpm. With a cylinder diameter S 150 mm and plate dimensions 300 mm × 400 mm, L = MS = 471.2 (mm) and the period R read or extract signal from the memory 1H 36 is
R = A / 2L x Y = 83.5 x 10 3 / 471.2 x 400 = 70.9 (m / s) and, as a result, the condition O <R <A / 2 is satisfied. The required time for exposure of films or films is about 1 minute and 20 seconds.

The dimensions of the snapshot image can be freely adjusted within a range that is determined from the above conditions to be
o <Y <M (mm)
The playback period varies with the dimensions of the snapshot image and can be adjusted using the play period setting device 28 shown in Fig. 8B. If this is done, the rotational speed of the cylinder and the exposure period are not changed.

 As has been described, in the second embodiment, the number of horizontal lines can effectively be angulated when the television signal is applied to the plate-making machine by combining intermediate virtual horizontal lines with the 525 horizontal lines of the plate. TV signal, which allows a fine print. While in the previous embodiment, only one intermediate line is inserted between the adjacent horizontal lines, it is also possible to insert two or more intermediate lines.

 Fig. 9 shows a block diagram of a third embodiment. In this embodiment, to obtain Y, M, C, and BK snapshots, the Y, M, C, and BK signals are applied to a color image scanning analyzer, which is a commercially available scanner, and to control the reading or extraction of the signal in synchronism with the rotation of the exposure device (i.e. the scanning analyzer 32), a rotation synchronization circuit 44 is used.

 To extract the signal from the image memory, the switching circuit 19 is switched on or off by a control signal from a gate switching control signal generating circuit 43. The output of the switching circuit 19 is taken into memory in odd and even 1H memories 24 and 26.

 Synchronization circuit 44 outputs a read control signal H by responding to a pulse signal outputted from scanning analyzer 32 in synchronism with the rotation of the exposure cylinder. The playback control signal H and the reproduced signal from the image memory 15 are applied to the gate switching control signal generator 43 which outputs a signal for opening the switching circuit 19.

The switching control signal generator 43 separates the synchronization signals from the video signal, assigns numbers, as shown in FIG. 2, to the video signal and outputs a signal for on / off operation or commutation of the switching circuit 19 in the order of the line numbers 283, 21, 284, ... in synchronism with the read signal H.

 The switch 19 passes the input video signal either to the even-frame memory 1E 24 or to the odd field 1H 26, depending on whether the signal belongs to the even or odd field, and the signal stored is retrieved according to a read command I or J signal from a generator 45 read control signals.

 A feature of the foregoing embodiment is that a commercially available scanning analyzer is used. In the case of a commercially available scanning analyzer, cupcake films are placed on a cylinder as shown in FIG. 6, and this cylinder is rotated at a speed of 140 or 200. lines per cm for an exhibition.

 In the ordinary scanning analyzer, the side corresponding to the original and the side corresponding to the exposure rotate in synchronism with each other and one can obtain photographs in enlarged dimensions and in reduced dimensions as well as in the dimensions of the original.

 In the previous embodiment, the production of the snapshots in the dimensions of the original, and also in enlarged dimensions, is possible by synchronizing the 525 lines of the television video signal with the speed of rotation of the scanning analyzer. Because the rotational speed of the commercially available scanning analyzer is fixed, that is, the rotational speed of this analyzer can not be adjusted to match the television signal. adjusts the speed of the television signal reading as a function of the scan speed of the scanner and the size magnification factor of the snapshot image.

 In the previous embodiment, the scanning direction of the 525 horizontal lines of the television signal is made to coincide with the Y direction shown in Fig. 6. Because the complete television picture comprises 525 lines while The scanning analyzer has a fixed speed of 140 or 200 lines per cm, the dimensions of the image can not be adjusted freely.

 In the case where the snapshot images are obtained by exposing 525 lines in the scanning analyzer, the magnification being set to the dimensions of the original, the concrete dimensions of the image of the diché are; assuming that the vertical and horizontal blanking periods are excluded, X = 3.5 cm and Y = 4.1 cm at the speed of 140 lines / cm, while X = 2.7 cm and Y = 3.3 cm at the speed of 200 lines / cm.

 An enlargement can be obtained as follows.

Cluster image dimensions are obtained with a magnification factor m, for example, by exposing 525 xm lines in the scanning analyzer, ie each horizontal line of the television signal is exposed m times in the scanning analyzer.

 Therefore, any integer can be used as an enlargement factor and the X dimension of the snapshot is determined when the magnification factor is set. With respect to the Y dimension, by setting the magnification factor by means of a snapshot size adjustment circuit (shown in FIG. 9), the number of read control pulses is determined ( identical to m) as well as the width of this pulse.

In the case where m = 2, for example, the signals inscribed in the memories 24 and 26 can be read twice, and at a speed of 140 lines / cm, the dimensions of the photograph are 7.0 cm × 8. , 2 cm, the switching period of said switching circuit excluding the horizontal blanking period is 52.7, us, the read control signals
I and J are A / m = 100 ms and R / m = 49.7 ms, the rotation speed of the scanning analyzer is 10 revolutions / second, the circumference of the cylinder is L = 165 mm, and the period exposure is about 100 seconds.

 The previous embodiment can therefore use a commercially available analyzer without modification since the reading of the signal is controlled in synchronism with the rotation of this analyzer.

Figure 10 shows a fourth embodiment. The signal extracted (or reproduced) from the memory 15 is applied to a switching circuit 19 as well as to a generator 43 of switching control signals. At the switch control signal generator 43 is applied a synchronization signal K which is synchronized with the rotation of the scanning analyzer 32 and has a width calculated from the dimensions of the image of the image and which is emitted by a circuit 46 for adjusting the image size of a picture, a synchronization circuit 44 and a generator 45 of read control signals. In the logic circuit 43, the horizontal and vertical synchronization signals are separated from the video signal applied from the image memory and the switching control signals L1 and L2 are generated at
1 2 separate synchronization signals and applied to the switching circuit 19 under the control of the synchronization signal K.

 More particularly, the switching control signal L1 for a line of the even frame, such as the lines 284, 285, ... first, then the switching control signal L2 for a line of the odd field, as the lines 22, 23, ..., are applied to the switching circuit 19 in synchronism with the synchronization signals of the video signal and under the control of the synchronization signal K. FIGS. 13 show the details of the control signals L1 and L2 door switching.

 As for the television signal, the horizontal scan lines of the even frame and those of the odd field must be correctly interleaved in the order of the lines 21, 284, 22 ... The correct arrangement of the lines in the line can be obtained. order of line numbers 22, 285, 23, 286, 24 ... by delaying the even-numbered lines of 1/2 V, i.e. 1 / 60th of a second. The signals M1 and M2 triggered by the switching signals L1 and L2 comprise the video component, and the signal M3 obtained by combining the signals M1 and M2 with the signal M1 delayed by a circuit 47 with a delay of 1 / V , includes video components arranged correctly.

 However, the video signal M3 is an intermittent signal so that it is not suitable as the exposure scanning signal to be applied to the scanning analyzer 32. Consequently, this signal passes through a holding circuit 48 serving to transform it into a continuous signal. The continuous signal thus obtained is applied via the switching circuit 22 to the memory 24 to be inscribed therein as a function of a gate switching signal I1 applied from a gate switching signal generator 23. is retrieved from the memory 24 as a function of a read command signal J1 applied from the read control signal generator 45 or is written in the memory 26 as a function of a gate switching signal 12 applied to from the gate switch signal generator 23 and extracted from the memory 26 as a function of a read control signal J2 applied from the read control signal generator 45. In this way, the video signal is successively applied to the NTSC decoder 29.

 In this embodiment, a commercially available scanning analyzer is used and the direction of horizontal line scanning of a complete television image as well as the direction of the exposure scanning lines in the scanning analyzer are brought to be perpendicular to each other. By adopting the perpendicular relationship between the direction of the horizontal lines of the television signal and the direction of the scanning lines of the scanning analyzer (ie the direction of exposure), it is possible to adjust the size of the image of the image independent of the number of horizontal lines of the television signal. Moreover, by sending to the circuit This synchronization 44 from the commercially available analyzer 32, a pulse signal synchronized with the rotation of the cylinder of this analyzer, it is possible to simultaneously obtain three primary color signals, that is to say the Y (yellow), M (magenta), and C (cyan) signals.

 Fig. 11 shows an example of the arrangement of the films or films to be exposed to the exposure section of the scanning analyzer 32. As can be seen in FIG. 11, the scanning direction for the exposure is the same as the direction of rotation of the cylinder, but the scanning direction of the horizontal lines in the television image is perpendicular to the direction of rotation. .

 As an example of specific numerical values, the dimensions of the image of the finished image are 3.75 cm × 5 cm, the scanning speed of the scanning analyzer of the processing apparatus is 140 lines / cm. , and the rotation speed of the exposure cylinder is 10 revolutions / second.

 Fig. 12 is a partial view on a large scale showing an example of the method of quantizing the television image. With the scanning performed on the width of 5 cm at a speed of 140 lines / cm, the number of exposure scanning lines forming the image is 5 × 140 = 700. A horizontal scanning line is therefore quantified in 700 picture elements. Since the television image comprises 525 horizontal lines, the image of the photograph is, in this case, formed by a mosal or matrix of pixels comprising 525 rows and 700 columns.

 Because the signal applied to the scanning analyzer 32 has a perpendicular relationship to the direction of horizontal scanning of the television image, the signal detection order is: the elements 284, 22 , 285, 23, ... of the first column, the elements 284, 22, 285, 23, ... of the second column, the elements 284, 22, 285, 23, ... of the third column and thus immediately to the end, that is to say the elements 284, 22, 285, 23, ... of the seven-hundredth column.

 The reading or extraction of the signals must be synchronized with the rotation of the cylinder of the scanning analyzer 32.

A synchronization pulse is obtained every I / 10th of a second from the analyzer 32. These pulses constitute the synchronization signal K. The pulse width is preferably set at 90.7 ns. to meet the dimensions of the image of the finished print job. This width corresponds to the case of a quantization of a horizontal scan line of the 700-element television image.

 The signal from the image memory is converted into the form of the signals for making the images as described previously.

 Figure 14 shows the mutual relationship of the individual signals. The relationship of the L, L2 signals is shown in more detail in FIG. 13.

 The video signal M3 is applied via the switching circuit 22 to the memory 24 to be registered therein as a function of the gate switching signal I1 and is extracted therefrom as a function of the read control signals J1. The reading speed at this time is determined by the dimensions of the image. This period is y seconds. Since L = S and: y = L: Y in Fig. 11, y = tY / Lw Therefore, from L = 7.5 cm, Y = 3.75 cm and 4 = lolo seconds (10 turns / second), we get y = 1/20 seconds.

With the memories 24 and 26 used for the odd and even rows respectively, as shown in Figure 10, the condition Q-1/60 s. <y can be satisfied in a range <y. In this way, fractions of the video signal each converting a time interval of y seconds, are each successively applied during a period X of the NTSC decoder 29. This input applied to the decoder
NTSC 29 is thus transformed into R, G and B signals which are themselves converted by the converter into signals
Y, M and C applied to the scanning analyzer 32 of the processing apparatus. In this case, the exposure period is 1/10 sx 700, that is 70 seconds.

 Because in this embodiment, the scanning direction of the horizontal lines of the television image and the direction of the scanning lines of the image analyzer (ie, the exposure direction) are made to be perpendicular to each other, it is possible to freely establish a desired size of the image of a photograph without any limitation imposed by the number of horizontal scanning lines of the television image and to determine the value of n of Figure 12 from the dimensions of the desired image and the number of scanning lines of the analyzer.

 Furthermore, since the three video signals for making cliches, i.e. the Y, M and C signals, can be simultaneously applied to a color image analyzer commercially available in synchronism with the latter simply by receiving from the latter a pulsed signal synchronized with the rotation of the analyzer cylinder, the commercially available analyzer can be used without any modification.

 Fig. 15 shows a fifth embodiment.

In this embodiment, a signal of a frame is applied via a switch 22 to a distribution circuit 39 which divides its input signal into three signals, i.e. a signal applied to a delay circuit 49 delaying the signal by A seconds, a signal applied directly to an OR circuit 50 and an applied signal, via a delay circuit 51 2A delaying the signal of 2A seconds, to the circuit OR 50. The signal applied directly to the OR 50 circuit and the signal applied to the circuit
OR 50 after being delayed by 2A seconds through the timing circuit 51A are combined in the OR circuit 50 and the resulting combination is halved in the average circuit 52. The average signal of the average circuit 52 dividing the input by 2 and the delayed signal of A seconds through the timing circuit 49 are combined in an OR circuit 53 whose output is applied to a memory 1H 54 and then to the decoder NTSC 29.

 Figure 16 shows the relationship of these signals. The signal (1) is extracted from the image memory, the signal (2) is obtained by a delay of A seconds of the signal (1) extracted from the memory to image the signal (3) is obtained by a delay of 2A seconds of the signal (1) extracted from the image memory, the average signal (4) is obtained from the signal (1) extracted from the image memory and the signal (3) is obtained by timing of 2A seconds from the output of the image memory, the signal (5) is obtained by combining the signal (2) obtained by delaying A seconds of the portion of the image memory and the average signal (4; in the memory 1H, and a signal (6) is obtained by reading, that is to say, extraction, of the stored signal (5).

Referring again to FIG. 15, it can be seen that the signal (1) of FIG. 16 is distributed by the distribution circuit 39, the signal applied to the delay circuit 49
A is transformed by being delayed by this signal circuit (2), the signal (1) directly applied to the OR circuit 50 and the signal (30) having passed through the delay circuit 51A are combined in the OR circuit 50 whose output is divided by 2 in the average circuit 52 so as to give the signal (4), the signal (4) and the signal (2) having passed through the delay circuit 49 are combined in the OR circuit 53 so as to give the signal (50) which is written in the memory 1H 54, and the signal (6) is extracted from the memory 1H
54 and is applied to the NTSC decoder 29.

 In this way, a signal approximating the video signal of a complete image can be obtained from the video signal of a frame by the interpolation method of averaging, so that a uniform image can be obtained. With respect to a television image consisting of two frames if this image contains moving parts, there is a blur at the location of these moving parts. To remedy this, the Applicant has used the method mentioned above.

 A sixth embodiment of the invention will now be described with respect to a desired television image picking method for printing from the video signal recorded in the video tape recorder of FIG. 1. The selection of an image The desired television mode for printing from the video signal recorded on the video tape and the precise designation of the image chosen to the printing plate manufacturer are very difficult operations. Usually, it is common practice to view the contents of the videotape on a recording device connected to a VCR, to stop the tape when a desired image is viewed, to photograph this image with a '' Polarold '' device while reading and recording the counter digit of the VCR and then giving the camera manufacturer the photograph, tape and counter digit. The snapshot maker "visualizes" the videotape on a VCR, stops the VCR when the specified counter number is reached, and chooses from among the corresponding television images a television image that appears to be the one that most closely resembles the image of the photograph obtained with the camera "Polaroid". With this method, the designated image can not be accurately selected. With the present invention, the image number generator 12, as shown in FIG. 1, is used to obtain television picture numbers and record them on the video tape and, in addition, the indicator 13 is used. a television picture number to retrieve and designate the number of a television picture to be printed, so that a specified picture can be selected on the video tape and applied via the video recorder ll to the television picture memory.

 In this case, a time code signal generator for generating time, minute, second and image signals is used as the television picture number indicator 12. For example, a SMPTE time code signal generator or VITC signal generator (vertical gap time code) may be used. With this first generator, the signal is inserted into the audio track of the video tape and with the latter, the signal is inserted into the vertical blanking period of the video signal.

When the TV signal is recorded with the video recorder, the time codes are recorded at the same time. At the time of viewing, a television image to be printed is determined by a reproduced fixed view and the image number of that image is specified to the printing plate manufacturer. The specified number of the image is set in the image number indicator 13 in the form of hour, minute, second and image. When the video tape is 1, viewed on the video recorder 11, the time code of the specified picture number is read by an image number reading device 55, as shown in FIG. 17, and the signal of the video playback device. reading 55 is applied to a setting device 56 or setting the image number. The image number indicator 56 detects the difference between the image number signal applied from the number reading device 55. image and a signal of a specified image number and, as soon as the difference becomes zero, the indicator outputs a pulse for operating a write control circuit 57, whereby the appropriate television image is stored from the video recorder 11 in the image memory 15. The output signal of the image number setting device 56 may be a pulse signal or a step-like signal, as shown in FIG. rise of the impulse or the step signal can be used as the write control signal.

 A seventh embodiment will now be described with respect to the exposure spot of the scanning analyzer 32 of FIG. 19. In commercially available color scanners, the light spot formed on the film or photosensitive film at The moment of exposure is mainly in the form of a dot as can be seen on the left-hand side of Figure 19, although in some analyzers the light spot has a rectangular shape. When the photographic film exhibited by analyzer 32 has large dimensions, we can see the 525 horizontal scan lines just as we can see on the cathode ray tube the 525 lines of the television picture reproduced when we observe these lines from a position close to the However, as regards the films, it is undesirable for the scanning lines to be visible there. The appearance of the scan lines can be prevented by adopting a rectangular shape of the light spot formed on the photosensitive film or film at the time of exposure, as shown on the right side of Fig. 19.The dimension has a value sufficient that the scanning lines do not appear, this dimension being preferably of the order of 1.5 to 3.5 times the scanning line and the dimension having a sufficient value suitable for maintaining the resolution of the television signal (about 5 MHz).

 With a scanning density of 500 lines / 25.4 mm, the dimensions of the cliché image are 27 mm (vertical dimension) x 36 mm (horizontal dimension), which is necessary to achieve line-by-line correspondence between 525 horizontal scan lines of the TV picture and scan scan exposure lines.

In this case, the dimensions of the exposure light spot on the photographic film may, for example, be
at l50m and b = 55) wu.

 When the scanning density is variable, with a density of 100 lines / 25.4 mm, the dimensions of the image of the image are 133 mm (vertical dimension) x 178 mm (horizontal dimension) while the dimensions of the light spot of The exposure is a = 700 to 750 μm and b = 250 to 300 μm.

 In this way, the scan lines can be made invisible in the snapshot image without sacrificing the resolution.

 Another embodiment of the present invention relates to a method for automatically specifying television images to be transmitted to the scanning analyzer and this other embodiment will now be described in detail.

 Figures 20A-20C show the system. On the publisher side, a VCR tape 63, on which a program containing television images to be used for making snapshots is recorded, is placed in a tape recorder (A) 64, as can be seen in FIG. 22A. This band 63 need not be specially produced. The VCR (A) 64 is a 19 mm or 25.4 mm type camera or any other device capable of reproducing still pictures. The rendered image can be viewed on a color control television 58 connected to the video recorder (A) 64.

 The editor selects the appropriate images for the print images by performing slow motion and still image viewing and photographs each selected image when viewing still images using a camera. Polaro1d '' 59 while memorizing the data relating to the numbers displayed by the VCR counter. Next, the editor provides the photograph 101 and the data 102 relating to the number displayed by the counter so as to obtain a television picture specification in a format, as shown in FIG. 20B.

 In accordance with the present invention, before switching from a fixed view reproduction to a cinematographic reproduction, the switch of a signal generator 65 is closed in order to record a signal of the latter on an audio track of the band at during a post-registration.

For example, with a 19 mm VCR, the audio signal is recorded on a CH-2 track simultaneously with the recording of the video and no signal is recorded on the CH-1 track.

 In accordance with the present invention, the signal from the generator 65 is recorded by post-recording on the empty track CH-1, as shown in FIG. 21. The VCR tape and the image specification (serving as the original) are supplied by the publisher to the manufacturer of printing plates, that is to say the manufacturer side of the plates. On the manufacturer side of the plates, there is, as shown in FIG. 20C, a video recorder (B) 66, a signal detection circuit 67 connected to the video tape recorder (B) and used to detect the signal recorded on the audio track CH-1 as well as a generator 68 of write control signals. The contents of the received tape are visualized, via the video recorder (B) 66 on the TV control 58. Before the image is specified by the editor and appears, no signal is present on the track CH -1. As soon as the specified image is reached, the signal that is recorded on the CH-1 track is detected. Upon detection of this signal, the write control signal generator 68 sends a write control signal to the image memory for recording a video image.

 Note that the television image that is stored in the image memory is the image that follows the image specified by the editor, i.e. the frame reproduced late with respect to the recording frame. In order to memorize the specified image itself, a signal must therefore be present at a position of the track that corresponds to the image immediately preceding the specified image.

 Fig. 22 shows an example in which a constructive arrangement for achieving this result is provided in the VCR (B) 66 on the printing plate manufacturer side.

More particularly, the position of an audio head 70 is slightly shifted towards the video head side.

For example, in a 19 mm video cassette recorder, the running speed of the tape 71 is 95.3 mm / second, and since the lavender moves 1.59 mm in 1/60 second, the audio head can be shifted in such a way that
S '= S - 1.59 mm as shown in FIG. 24.

 In Fig. 23, the reference 72 designates a guide cylinder, the reference 73 an erase head and the reference 74 a cassette.

Because only one printmaker works with multiple publishers, it is best to edit the VCR (E) 66 on the camera manufacturer side
Of course, it is possible to shift the radio head of the video recorder (A) 60 so that
S '= S + 1.59 mm instead of modifying the video recorder (B) 66 and, in doing so, the same effects can be obtained.

 As another possibility, it is possible to slightly vary the passage of the band 71 and, in this case, one can still obtain the same effects.

 The signal generator 65, used in the previous embodiment, is a low frequency oscillator circuit operating at 1 KHz or a similar frequency and can therefore be manufactured inexpensively. The write control signal generator 68 is an electronic switch for on / off control of the image memory according to whether the low frequency signal of 1 KHz or similar frequency from the circuit 68 is present or not present. , so that this generator can have a simple circuit structure and be manufactured at a low price.

 Further, it can be verified whether the television image stored in the image memory matches the photograph when naming or specifying the image by extracting it from memory (i.e. reading this picture).

 The foregoing embodiment of Figs. 20A-20C, which is the basic system for specifying television images, does not include a mechanism for the editor to re-select, if necessary, an image that has been previously selected. .

 Fig. 23 shows another embodiment that includes such a mechanism. This embodiment is similar to the previous embodiment until post-recording of the signal. Fig. 24 shows the internal structure of a video recorder (A ') 75 which is on the publisher side and which is used in the present embodiment. This embodiment is characterized by a signal detection audio head 80 disposed separately from the audio head and thereby detecting another signal in time. This head is intended to detect in advance the post-recording signal of the track CH-1. As regards the construction of the video recorder, this head is preferably disposed immediately before the existing audio head 81 or it can be placed before or after an erase head 82.

 When the editor wants to re-view an image that has been previously selected, he can obtain the still image reproduction using the next signal processing.

As shown in Fig. 23, the post-recording signal recorded in Fig. CH-1 is detected by the post-recording signal detection audio head 80 and is applied to a signal detection circuit 76. The detected signal is then delayed for a predetermined time by a delay circuit 77 before being applied to a fixed gating control signal generator 78 which provides a still picture control signal to a remote control terminal of the video recorder (A). 75).

 In this way, the publisher can re-view any desired image that has been chosen previously.

 In Fig. 24, the reference 83 designates a guide cylinder, the reference 84 a strip, and the reference 85 a cassette.

 Since the strip 63 is the same as that of the embodiment of FIGS. 20A to 20C, the same effects as in the embodiment of these figures can be obtained on the printing plate manufacturer side or the test manufacturer. .

 One can also adopt the same design as in the previous embodiment on the manufacturer side of printing plates or proofmaker. Figure 25 shows an example of such a case. Here, a still image control signal outputted from a fixed image control signal generator 78 is not applied to the remote control terminal of the video recorder (A ') 75 but to the image memory. When the po-st-recording signal detection audio head 80 is disposed 10 mm before the existing audio head 81, the timer is suitably 88.2 milliseconds. In Fig. 25, reference 63 denotes a VCR tape, reference 76 a recording signal detection circuit, reference 77 a delay circuit, and reference 58 a color control television.

 Figure 26 shows another embodiment of the invention. In this embodiment, on the editor side, the post-recording signal is recorded again on the track CH-1 at a location thereof which corresponds to the immediately preceding frame. In this case, the VCR on the manufacturer's side of the printing plates or test manufacturer does not require any modification. This embodiment is the same as the embodiment described above with respect to FIGS. 20A-20C and 23 until the post-recording of a 1000 Hz signal or the like on an empty track such as the CH-1 track.

 The editor rewinds the tape 63 and then turns on the video recorder 75 for cinematographic reproduction while establishing a state for post-recording on the CH-1 pioneer. If the video recorder (A ') 75 is of the "Umatic" type 19 mm, a post-recording signal detection audio head is provided as shown in Fig. 24.

 The post-recording signal present on the CH-1 track is detected by the post-recording signal detection circuit 76 and is delayed by the timing circuit 77 to be applied to a switching circuit 80 which is connected to a 79 post-registration signal generator. The signal, which has been delayed for a predetermined period of time, switches the switching circuit 80 and, at this time, a signal of 1000 Hz or similar frequency is applied to the CH-1 track and is recorded therein. The forward end of the newly recorded signal is adapted to be offset in advance of that of the already recorded signal by a distance corresponding to one of the frames at the number under which the image, at the moment of the recording, must be visualized by being delayed.

 With this arrangement, on the printing copy maker side, the specified image can be stored without changing the video recorder of Fig. 20C.

 This embodiment also allows, on the publisher side, to re-view an already selected television image as a still image reproduction in the manner previously described with respect to FIG. 23. In FIG. reference 78 denotes a still image control signal generator, reference 58 is a control television, and reference numeral 59 is a "Polarold" photographic camera.

 The post-recording signal may as well have a high frequency or greater than 10 KHz. In the case where the post-recording is carried out superimposed on the signals already recorded on the CH-1 or CH-2 track, a frequency to which the human ear is sensitive and which, moreover, has no harmful effect on reproduction of the program, can be chosen.

 The track for the post-recording is in no way limited to the audio tracks and one can also use the control track, the vertical deletion region of the video track or the marking track. When using, for example, the control track, in which a rectangular wave of 29.97 Hz is recorded, the frequency of the signal to be recorded in superposition to the aforementioned rectangular wave can be chosen so that it can be separated sufficiently using a filter.

 The post-recording signal can have any desired period as long as it hinders the specification of the next image and the shortest period is 1/60 second.

 As described, the system used to specify and select images according to the present invention is characterized by high reproduction after image selection and does not require much time and effort. In addition, it only requires the addition of a simple electrical circuit and a slight modification of the video recorder without harming the proper function of the processing apparatus and is inexpensive.

 Another embodiment of the invention will now be described. In ordinary printing, a color film is provided as an original and is placed on the scanning analyzer to produce yellow (Y), magenta (M), cyan (C) and black (BK) images.

 Although the test is submitted to the customer, it is common practice to evaluate the finished photograph by comparing it with the original color film.

 In the first embodiment of the apparatus, for preparing television image printing snapshots, as mentioned previously, the Y, M, C and BK snapshots for printing are made directly from an image of TV. Although the proofs of these shots are taken before the printing is done, these images can not be compared with an original color film with respect to an evaluation. Although it may be thought that it is possible to place the VCR or the control TV at the manufacturer of snapshots or proofs, this is complicated and inconvenient.

 In addition, the editors who order the shots or prints are not used to VCR tapes and are uncomfortable with such tapes - the content of which can not be seen directly. The following embodiment of the present invention solves the above problem by providing a color film at the same time as the photos.

 Figs. 27A and 27B show examples of the arrangement of films to be exposed on the exposure roll of the apparatus according to the present invention. In the example of FIG. 27A, a color film of the same dimension as the pictures is obtained and, in the example of FIG. 27B, a color film of smaller size than that of the pictures is obtained.

 Fig. 28 shows a color film exposure section of this embodiment of the apparatus.

 The three primary color signals, i.e., the R, G, and B signals, obtained from the NTSC decoder 29, are applied, via a color correction circuit, to the analyzer 32. scanning for conversion into four print color signals which are themselves applied to a cylinder exposure section. In accordance with the present invention, the R, G and B signals are also applied to a color signal exposure section.

Since we can now easily use laser light sources, we will describe an example of using a laser as a light source.
A 6328 A He-Ne gas laser was used as a red light source (R), a 5145 A Ar laser as a green light source (G) and a 4416 A He-Cd gas laser as the source blue light (B). These laser beams (R), (G) and (B) are modulated by the respective electrical signals (R), (G) and (B) and the resulting modulations (R) ', (G)' and (B) are synthesized in a light synthesizer 82 so as to give a single laser beam. The light synthesizer 82 includes mirrors. The resulting modulated beam (R) '+ (G)' + (B) 'is projected onto a film 83 so as to effect a color film exposure.

 Figure 29 shows another example of the color film exposure section. In this example, the three exposure laser beams are not combined but are projected directly. In this case, the light sources have defined dimensions and they are arranged in columns.

In this example, delay circuits or delay circuits 84 and 85 are provided for the respective signals G and B, so that the three signals can be synchronized to the film 83.

 The light sources could also be arranged in rows.

 In addition, it is also possible to use as light sources 81 tungsten lamps or conventional xenon lamps. In this case, the necessary colors can be obtained using appropriate filters. For example, Latten filters nO 29 (R), nO 61 (G), and nO 47 (B) manufactured by Kodak can be used. In this case, the voltage of the sources can be modulated with the signals R, G and B so that one obtains the modulations (R) ', (G)' and (B) 'intended for an exposure.

Although in the above description, the decoder
NTSC 29 was placed immediately before the scanning analyzer 32, so it is for the purpose of facilitating the understanding of the description However, this position is not limiting and the NTSC decoder 29 can also be placed before or after the memory 15 of image. In this case, three sets of constituent elements, respectively for the R signals,
G and B, were provided between the NTSC decoder 20 and the scanning analyzer 32.

Since the above embodiment has the structure described above, it is possible to obtain a color film at the same time as the Y, M, C and BK snapshots directly from the television signal, so that it is possible to check the quality of the image of the finished image and also to evaluate the proof in comparison with the color film
Referring now to FIG. 30, a description will be given of a processing apparatus according to another embodiment which simultaneously provides a picture and a color film. In this embodiment, a scanning analyzer 90 for producing a snapshot and a scanning analyzer 92 for producing a color film are provided separately. The color television signals are divided into three primary color signals R, G and B. In the scanning analyzer 90 for making the images, the three primary color signals are transformed into print signals representing the four colors Y , M, C and BK by the converter RGB-Y.MC.BK 96. The converted signals are applied to an exposure head 100 through the color correction circuit 98. A light emitted by the exposure head 100 is modulated according to the amplitude of the television signals which are divided respectively so as to give the four aforementioned colors Y, M, C, BK.The modulated light beams are projected on a color film mounted on a cylinder 102 to provide pictures for the colors Y, X, C and BK. The linear displacement of the exposure head 100 and the rotation of the cylinder 102 are performed by a driving device 104. The scanning analyzer 92 for producing the color films is arranged as shown in FIG. representing the three primary colors R, G and B are directed on a light modulator 106 so that the light rays of the three primary colors R, G and B previously applied to the light modulator 106 are modulated from a light source The light modulator output rays are concentrated to give a single beam of light by a light synthesizer 110 formed, for example, by a mirror. The single beam of light thus obtained is projected by an exposure head. 112 on a color film wound around a cylinder 114. The exposure head 112 may have dimensions smaller than the exposure head 100. servan t to make clichés. The exposure head 112 and the cylinder 114 are driven by a driver 116. The operations of the two drivers 104 and 116 are synchronized by a drive control circuit 118 to simultaneously produce the four shots. print and a color film. The scanning analyzer 92 may be arranged as shown in FIG.

 In the previous embodiment, different scanning analyzers are used to make a color film and a printing plate. However, it is possible to apply the known treatment apparatus to make a printing plate directly from an original colored test. The conventional processing apparatus comprises an image reading device and a recording device. If four shots are prepared directly from the television signals, it is not necessary to read a colored original proof, which exempts the scanning light receiving analyzer of an image reading device. If, in the case where one tries with the conventional processing apparatus to prepare four snapshots directly from television signals, the scanning analyzer which receives the light and which is not indispensable is replaced by a head A color film manufacturing exposure apparatus is provided as shown in Figs. 28 and 29, and a snapshot and a color film can then be prepared from the television signals simultaneously.

Referring now to FIG. 31, a processing apparatus having yet another embodiment which can prepare a picture in which a television picture and a color film picture are synthesized is described. Fig. 31 is a block diagram of the processing apparatus according to the embodiment. The television signals are divided into three first primary color signals R1, G1, and B1 by an NTSC decoder 94. These signals
R1, G1 and B1 are applied to one of the input terminals of an image mixing circuit 120.In addition, three second primary color signals R2, G2 and B2 emitted by the ordinary playback device 122 images are applied to the other input terminal of the 120 image mixer circuit. The image mixing circuit 120 is of the same type as, for example, a video editing switching system or special effects generator used, for example, in a television studio. This image mixer circuit 120 synthesizes the signals applied to the two input terminals. The main functions of the image mixing circuit 120 consist in introducing a desired image into a portion of a screen using the means known in the art as "Chroma Key", a progressive erasure. indications of the screen, a desired distortion of the images or a display of several images.The device 122 for reading images comprises a cylinder 124 around which is wound a film or original color paper, a photoelectric head 126 to transform into electrical signals the light beams reflected by the original color film or paper wound around the cylinder 124 where the light beams passing through the material of the original, and an amplifier 128 to amplify an output signal of the photoelectric head 126 and to send an amplified signal to the circuit 120 image mixer.

The cylinder 124 and the photoelectric head 126 are driven by a driving device 130. The output signals (tris primary color signals RO, GO and BO) of the image mixing circuit 120 are applied to the analyzer. 90 which serves for the manufacture of printing plates and which is arranged as shown in Figure 30. The respective operations of the drive devices 130 and 104 are synchronized by a drive control circuit 132.

The operation of the processing apparatus according to the above embodiment will now be described with respect to the case in which an image is introduced into a portion of the screen using the means known in the art as "Chroma. Dey ". In this case, an original color film having a blue background is disposed on the cylinder 124. The original film is scanned, i.e. scanned, by the photoelectric head 126. At this time, three second signals primary colors R2, G2 and B2 are emitted. These R2 signals,
G2 and B2 and the first three primary color signals
R1, G1 and B1 are synthesized by the "Chromo Key" in the image mixer circuit 120. In this case, a television image is introduced into the blue background of the original color film. The relationship between the dimensions of the introduced television picture and the color film picture dimensions correspond to the relationship that exists between the picture. number of scan lines applied to the television image and the number of scan lines applied to the color film image. In this case, 525 scan lines are applied to the television image. The number of scanning lines applied to the color film image is defined by the dimensions of this color film and by the scanning density with which the photoelectric head 26 is actuated. We will assume that the color film has dimensions of 56 x 67 mm for example and that the scanning density of the photoelectric head 126 is 500 lines / 25.4 mm. The number of the lines of this applied to the Color film is then considered to be around 1100 with regard to the 56 mm length of the color film. Therefore, if the number of scan lines applied to the introduced television picture is chosen so that the ratio of this number of scan lines to the number of scan lines applied to the color film image is 1: 1, then the dimensions of the TV image input-correspond to 26.7 x 32 mm.If the ratio between the number of scan lines applied to the introduced TV picture and the number of scan lines applied in the image of the color film is equal to 1: 2, then the dimensions of the television image introduced are 13.4 x 16 mm. In other words, any desired dimensions can be given to the introduced television image by modifying the ratio between the respective numbers of the scan lines applied to the two images. The ratio between the respective numbers of the scan lines applied to the two images can be determined by changing the conditions under which the television signals are read into the image memory.

 As described above, the previous embodiment corresponding to FIG. 31 makes it possible to create a new image that can not be obtained with conventional scanning analyzers, for example a synthesized image prepared from the image of a color film and a television image or a special effects image. Conversely, it can be seen from the foregoing description that an image of the color film can be introduced into a television image.
