Abstract

The present invention relates to a method for transposing film images reproduced from original films onto a photosensitive material. This method consists in carrying out a scanning of original images mounted on image cylinders 1A, 1B and 1C driven by motors 2A, 2B and 2C, to generate image signals in series. These image signals are then transmitted to a first addressing memory 35 of a memory disk 36, then transferred to a second memory disk 37, while the addresses of the image signals are changed according to the selected reproduction parameters. The images are finally recorded as a function of the signals transmitted by the second memory on a photosensitive material mounted on a reproduction cylinder 21. Use: reproduction of images or parts of original images from films. (CF DRAWING IN BOPI)

Description

1. The present invention relates to a method for transposing

  images of films reproduced from original images on a photographic material

  tosensible. In conventional film-making machines such as a color scanning device or a color facsimile, to reproduce

  a series of original films with different coloring conditions

  such as different tones, densities and color gradations

  the color conditions and magnification scale of each original film should be able to be appropriately varied. However, these f

  original films can not be reproduced on the same recording film.

  during a single operation, and are thus recorded one after the other on recording films according to the reproduction conditions and the magnification scale chosen. As a result, only an original film is mounted on the color scanning device, and these reproduction conditions

  as well as its magnification scale are determined for an operation.

  As a result, to reproduce images of the film in different

  reproduction conditions and under different magnifications on a pho-

  tosensitive according to the desired reproduction, the separating films of

  their, obtained by scanning the original images one by one as described above.

  are developed and fixed on a transparent film, and this film developed as well as the color separation films are printed on another film

  photosensitive, in order to obtain a reproduced film with color separation.

  However, according to this method, the original films are reproduced

  one by one depending on the color conditions and the enlargement conditions.

  color separating films obtained from a color should be placed precisely on the

  to obtain the reproduced film with color separation. This process requires much

  time and work. In addition, it requires another recording film.

  This is not an economical solution.

  Recently, a scanning device has been developed which can directly record reproduced images under different reproduction conditions and under different magnifications on a recording film.

  in the desired reproduction positions. However, in this realization

  when each original image is reproduced by scanning, an original image

  ginal is mounted on an image cylinder and its reproduction conditions and

  are individually fixed.

  Therefore, an object of the present invention is to realize

  a process of reproducing film images from original films on

  a photosensitive material, which is fast, stable and reliable and does not

  do not feel the aforementioned disadvantages.

2.

  This is why the present invention proposes a method for transmitting

  to put pictures of films reproduced from original films on

  photosensitive processes, comprising the following steps:

  a) Scan the original images in parallel using a

  image-scanning system, to obtain lines of image signals, b) to align the image signals in series, c) to store the aligned image signals in a first memory,

  d) Transfer the image signals stored in a first

  in a second memory, while the addresses of the image signals are changed according to the selected reproduction parameters, e) Recording the film images on a photosensitive material in the desired reproduction positions, according to the image signals

  read in the second memory by image recording means.

  3. Each image scanning device A, B or C comprises an image cylinder 1A, 1B or 1C on which are mounted the original images, a motor 2A, 2B or 2C for driving a drive shaft connected to the image cylinder, a pulse generator 3A, 3B or 3C such as a rotary coding device mounted on the drive shaft, a threaded rod 5A, 5B or 5C driven by a motor 4A, 4B or 4C, an image scanning head 6A , 6B or 6C and a pulse generator 7A, 7B or 7C such as a linear coding device. The rotary coding device 3A, 3B or 3C and the linear coding device 7A, 7B or 7C transmit pulses to a timing circuit 12A, 12B or 12C. The input timing circuit 12A, 12B or 12C transmits timing pulses or clock pulses to a control circuit 9A, 9B or 9C, a color operational circuit 10A, 10B or 10C, a determination device

  magnification 11A, 11B or 11C and a combiner 13A, 13B or 13C.

  Before the original images are mounted on the image cylinders IA to 1C, the number of images and the dimensions of the selected areas of the original images, as shown in Figs. 2a to 2f are introduced into an image preselection member 30 by data input means such as a keyboard, and simultaneously the reproduction conditions and the reproduction scales of the original images are also introduced into the image preselection members 30. Then, the output signals of the

  preselection organs images3O, corresponding to the selected areas of the images

  as shown in FIGS. 2a 'to 2f' are obtained by multiplying

  the scale of reproduction by the dimensions of the selected ranges of

  origin, combined with the number of images. As shown in fig. 3, the

  The selected units are visualized on a display device such as a cathode ray tube, contained in the preselection members image 30, the

  ratio of the selected areas to the total area of the visualization device

  corresponding to the total storage area of the first memory to be dis-

that 36.

  The selected areas of images are arranged appropriately on

  the display device by a control lever according to the results

  Haites. The best results will be obtained by using a miniordina-

  tor. On this occasion, space, to record registration marks

  for positioning and to have the time to vary

  reproduction of the images, can be booked around each separate

  lectionnée. Next, we decide which of the original images corresponding to the selected image will be mounted on the image cylinder 1A, 1B or 1C. For example, the original images b, f and c, corresponding to the selected ranges b ', f' and c 'which are arranged side by side on the display device, are intended to be respectively mounted on the image cylinders 1A, 1B and 4.

  1 C. Then, the original images d, e, a, corresponding to the selected ranges

  born from, e 'and a', will have to be mounted on the cylinders 1A, 1B and 1C. By

  for example, the original image d, corresponding to the selected range of, must -

  to be mounted on one of the cylinders 1A and 1B, on which the original images b and f, corresponding to the selected ranges b 'and f', are mounted and whose scanning is finished before the beginning of the scanning of the selected range of from the original image d. If the original image d is to be mounted on the cylinder 1A, the original images e and a, corresponding to the selected ranges e 'and a',

  must be mounted respectively on cylinders lb and lc, of the same type.

  than the one described above.

  This information described above is introduced into the prepositioning member 30, and then the original images a to f are mounted

  on the cylinders images 1A to 1C as shown in FIG. 4. All these operations

  in such a way that the unnecessary parts of the

  originals can not be reproduced and so the

  transmitted data can be effectively stored in the first disk

  36 for a purpose different from the reproduction operation described above.

  under. The reproduction conditions defined by the colored tones, the color correction, the gradations, the illumination and shading densities,

  etc. can be obtained through the use of a simulator

  as described in Japanese Patent Publication No. 5579448 (Disclosure No.

  Japanese Patent Application Number 53-155954). These reproduction conditions and these scales of reproduction are introduced in registers of the device for setting up the data of the image prepositioning means 30 such that

described below.

  Each original image b, d, f, e, c or a, mounted on the cylinders

  1A, 1B or 1C as shown in FIG. 4, has a selected area, in the

  which two points P1 (xbo, YbO) - P12 (xal, Yal) are positioned in the corner

  upper left and lower right corner. These selected points are detected

  by a viewer (not shown) connected to the scanning head 6A, 6B or

  6C, and their distances, from an origin that is marked on each cy-

  lA, 1B or 1C, are measured by pulse generators 3A, 3B

  or 3C and 7A, 7B or 7C, as being the numbers of pulses along the axis of the cy-

  lindres and according to the periphery of these cylinders.

  The coordinates of the selected points, which are represented by the number of pulses counted by pulse generators 3A, 3B or 3C

  and 7A, 7B or 7C, are transmitted through adjustment circuit 9A, 9B or 9C.

  The coordinates of the selected points of the original images

  on the cylinders 1A, 1B or 1C, together with their scales of reproduc-

  5. tion and the image numbers, are introduced into an operator circuit 34 such

  computer for the first disk storage 36. In the operational circuit,

  34, the coordinates of the selected points of the original image are trans-

  formed into corresponding addresses for the first memory disk 36, for example

  pl points selected P1 (xbO, YbO) and P2 (xbl, Ybl) of the original image b, and transformed into addresses (XbO, YbO) and (Xbl, Ybl) of the start and end points of the scan of the image reproduced b 'on the recording film

  as shown in fig. 3, and the address signals having their addresses trans-

  formed are written on a first address memory 35.

  Then, the original images a-f, mounted on each cylinder 1A or 1C as shown in FIG. 4, are scanned photoelectrically by a

  sampling head 6A, 6B or 6C to obtain analog image signals.

  The analog image signals are transmitted to an analog-digital converter

  8A, 8B or 8C, in which the image signals are transformed into signals

  digital images that are transmitted to the control circuit 9A, 9B or 9C.

  Fig. 5 represents a portion of the control circuit 9A, 9B or 9C.

  Each original image requires an adjustment circuit. Assuming that the cir-

  Cooking 9A1 adjustment, for the original image, is shown partially in FIG. 5, the counters 40 and 47 count the numbers of clock pulses x and y, transmitted by the pulse generators 3A and 7A through the circuit

  input timing 12A. In the means of presetting the selected points

  42, 44, 49 and 51, the coordinates xbO, xbl, Ybo and Yb, selected points

  P1 and P2 of the image b are introduced. References 41, 43, 48 and 50 correspond to comparators. The comparator 41 compares the number counted x

  in the counter 40 with the value Xb0 introduced by the prepositioning means-

  42, and outputs a high level signal H when the number counted x has at least the value Xb0. The other comparators 43, 48 and 50 output a signal of

  high level H when the number counted x is at most equal to xbl, when the number

  counted is at least equal to YbO or where the counted number is at most

  equal to Ybl, in the same way as the comparator 41.

  References 45, 52 and 53 relate to AND gates. A switching circuit 46 transmits the image signal only because the door

  AND 53 transmits the high level signal H to the switching circuit 46.

  As a result, as shown in FIG. 4, when the original images

  gins, mounted on the respective image cylinders lA, 1B or IC, are scanned photoelectrically, each control circuit 9A, 9B or 9C emits signals

  images corresponding to the selected parts for the scan lines.

  Before the image signals are introduced by the control circuits 9A, 9B and 9C into the color operator circuits 10A, 10B and 10C, the reproduction conditions of the original images, which are stored in the 6. drawers of the setting devices. in place data of the preselection means images 30, are introduced in the color operator circuits

10A, 10B and 10C as follows.

  Fig. 6 shows an embodiment of a data setting device of the image prepositioning means 30, having two drawer registers 55 and 56, each storing the reproduction conditions and enlarging the original image. b or d, climb on the

  cylinder 1A. On this occasion, the conditions for reproducing the original image

  nale b, intended to be initially scanned, are introduced by the register to

  drawer 56 in the color operator circuit 10A. Then, the conditions of re-

  production of the original image d will be transferred, from the implementation

  place data, to the color operator circuit 11A as mentioned below.

  Fig. 7a represents the door signals for the original images.

  nales b and d which are transmitted by the control circuit 9A (that corresponding to the image b is transmitted by the AND gate 45 of Fig. 5). The signal shown in FIG. 7a prepares an inscription pulse as shown in FIG. 7b. So, the reproduction conditions and the original image b are adapted

  to be shifted from the shift register 55 to the register 56, by means of the

registration drive 57.

  Additionally, the reproduction scale, for the original image mounted on each image cylinder 1A, 1B or 1C except the first b, f or c, is

  introduced in the data set-up device for the expansion of

  11A, 11B or 11C and the controllers 13A, 13B or 13C, by means of the

  same inscription impulse as that used when the conditions of repro--

  duction of the original image are introduced into the color operator circuit

  A, lOB or lOC. The color operator circuit 10A, 10B or 10C performs an operation

  color control scheme such as masking, color correction,

  a dimming control, etc. An embodiment of such a circuit

  The color carrier is described in Japanese Patent Application No. 54-49077.

  The controllers 13A, 13B or 13C control the motors 4A, 4B or 4C, which control the speeds of movement of the image scanning heads 6A, 6B or

  6C depending on the scale of enlargement, with reference to a recording head

  26 described below. The magnification marking devices 11A, 11B or 11C control the reproduction scale by repeating or skipping image signals read periodically in a memory as described in the patent.

  Japanese Patent Application No. 54-65601 (Japanese Patent Application No. 52-131366).

  Thus the image signals, controlled in terms of enlargement

  which are transmitted from the enlargement recording device 11A, 11B and 11C, are locked in locking circuits 14A, 14B and 14C and

  are then written sequentially in memory units such as

  7. Buffer memories at one line of the memory 15. The registration time of the image signals is controlled by a timing controller 29, so as not to interfere with the read time. Figs. 8 and 9 illustrate one of the three timing control units of the timing controller 29 and a timing diagram of the pulses is shown in FIG. 8. It will be explained in connection with one of the three image scanning devices A, B and C. A start pulse A as shown in FIG. 9 (a), generated by the pulse generator 3A, is transmitted to the controller of

  timing 29 through a timing circuit 12A. A pulse of hor-

  box b, shown in FIG. 9 (b), which is transmitted by the chro-

  12A, is separated into three pulses c, d and e represented by FIGS. 9 (c), (d), (e), by a combination of a base-based counter 60, inverters 11 to 13 and AND gates A to A6. Counter 60 is cleared by

  a pulse e which is transmitted to the counter 60 by an inverter 14, a multi-

VI vibrator and an OR gate 01.

  The pulses c, d and e are transmitted to one of the terminals of a D-type flip-flop circuit 61, 62 and 63 (hereinafter referred to as the F / F circuit), which transmits output signals g, h and i represented by FIGS. 9 (g), (h), (i). The other terminals of the F / F circuits 61, 62 and 63 are held at a high level and are erased by the output signals of the OR gates 02, 03 and 04.

  The output signals g, h and i are then transmitted to

  F / F 64, 65 and 66, which are controlled by a clock pulse f represented by

  felt by fig. 9 (f), which is generated by a timing circuit 28.

  When the clock pulse f is at high level, the F / F circuit 64, 65, or 66 transmits a high-level signal transmitted to an OR gate 67, which transmits a signal.

  output j represented by FIG. 9 (j).

  A three-base counter 68 counts the output signal j transmitted by the OR gate 67, and outputs signals k and m represented by FIGS. 9 (k), (m). The output signals k and m are separated into three signals by a decoder

  69 which comprises a combination of inverters 15 and 16 and AND gates A7 to A9.

  The three separate signals in decoder 69 are transmitted to gates A10-

  A12, which are controlled by the clock pulses f transmitted by the timing circuit 28 and transmitted to the AND gates A10-A12 by a delay circuit 70. The AND gates A10-A12 emit signals n, o and p represented by the

  Fig. 9 (n), (o), (p), transmitted to an OR gate 71 which transmits at its output

  writing pulses q represented by FIG. 9 (q).

  The output signals n, o and p are transmitted to the OR gates 02, 03 and 04. The output signals of the OR gates 02, 03 and 04 are transmitted to the gate 8. OR 05. The reset of the counter 68 is performed by an output signal p, which is provided by the AND gate A12 and transmitted to the counter 68 via a multi-vibrator V2 and an AND gate A13, and the time of the reset of the

  counter 68 is delayed by timing circuit 72.

  By registration pulses obtained as mentioned above, the

  three sets of picture signals, which are blocked in the latch circuits.

  14A, 14B and 14C are stored in order of number addresses in the corresponding memory units of the memory 15, this operation being done simultaneously. Then, the three sets of image signals, stored in the memory units of the memory 15, are read simultaneously in the order of their address numbers by reading pulses generated by a timing circuit 28. One of the three sets of read image signals is selected in a data selector 16, depending on the transmission position signal

  transmitted by the prepositioning means of the image 30.

  The image signals selected for the original image af are transmitted by a data selector 16 to a first disk memory 36 via an interface 17, and are written to the first memory disk 36 by the use of the signals. addressed in the first

  addressing memory35, having the addresses of the first memory disk 36 corresponding to

  nesting at the coordinates of the selected points of the original images.

  The addressing signals, intended to be stored in the first address memory 35, are processed by the operator circuit 34. For example, when the relationship between the coordinates of the surface of each image cylinder 1A, 1B or 1C and the addresses of the first memory disk 36 are proportional with respect to the coordinates of the beginning and the end, for example J .......... and P1 (Xb0, Yb0), P3 (Xd0, Yd0, P5 (xf0 , Yfo), ....., and

  P2 (Xbl, Ybl) P4 (Xd1, Yd1), P6 (xflu, Yf1), .........

  as shown in FIG. 4 of each selected part of each original image, data that will be transmitted from the memory 15 to the memory disk 36, the start and end addresses of the first memory disk 36, for each scan line of an original image mounted on the cylinders images 1A, 1B

  or 1C, are processed by the operator circuit 34.

  Thus, the addressing signals obtained and intended to be stored

  in the first addressing memory 34 are shown in FIG. 10.

  In this figure (X0O, YO0) and (XOm, YOn) indicate the addresses of the first dis-

  that memory 36 corresponding to the selected points of the original image b,

  mounted on the image cylinder 1A shown in FIG. 4. The first and last

  lines, for example (Xo0O, YO0O), (X01, Y0O), ...... (XOm, YOO), and (XOO, YOn), (X0o1, YOn) ...... (X0m, YOn), show the start and end addresses of the first memory disk 36, which each correspond to a scan line of the image on the recording film mounted on the recording cylinder 21. in fact, only the addressing signals having such a start and end address on the memory disk 36 are transcribed on the first addressing memory 35.

  Then the formation of the image on the recording film becomes

made by means of an indicator 31.

  When the relationship between the coordinates of indicator 31, the

  addresses of the second memory disk 37 and the coordinates of the recording film

  mounted on the recording cylinder 21 are simply proportional,

  the coordinates of a copy block, taken from the indicator 31, are

  converted into corresponding addresses of the second memory disk 37

  by the operator circuit 32, acting in the same way as the operating circuit

  34 for the first memory disk 36.

  For example, to reproduce the film images on the film of

  recording, from the data stored on the first memory disk 36 by changing the dimensions of the image area stored on the first memory disk 36, the new addresses of the beginning and end of the second disk

  memory 37, which are processed by the operator circuit 32 according to the new

  parameters, are written on the second address memory 33, at the same time

time as the number of images.

  Alternatively, while the coordinates of the copy block for reproduction are taken by the indicator 31, in order to reproduce a

  part of the selected area of the image or to hide this selected area

  mask, the coordinates of the scan lines, on the recording film.

  recording, are taken by tracing the outline of the mask or the part of the selected area on the copy block by a cursor of the indicator 31, and

  Next, the coordinates corresponding to the outer contour are transformed.

  corresponding addresses on the second memory disk 36 by the operator circuit 32. Thus, the addresses corresponding to the contour are written on the

  second address memory 33, along with the number of images.

  In addition, when the mask has a particular shape defined by

  a mathematical equation, for example a circle, the coordinates of the center

  both (Xi ', Yi') and the radius being equal to r, the circle is expressed by the

mule (X._X ,,) 2 + (y, _y'y) 2 = r2

  Thus, the coordinates of the outer contour of the mask are indicated by the

lation:

(X4u, Yi + e r2- (XMn-).

  wherein XM 'represents a parameter.

  10. Next, the coordinates of the outer contour are transmitted to the

  32, and the start and end addresses of the second medium disk

  moire 37, corresponding to the scan lines of the mounted recording film

  on the recording cylinder 21 are processed in this circuit. The addresses

  its results are transcribed on the second address memory 33, at the same time

  time as the number of images as before.

  When the mask has a complicated form that can not be expressed by a mathematical equation such as the above equation, for example to select the image of a person on the original image, while the imagesignals are transcribed by the selector of data 16 on the first memory disk 36, the image signals are transmitted to the recording head 26 by a switching circuit 19 and a digital-analog converter 20, to record an image reproduced on the recording film mounted on

the recording cylinder 21.

  Then the necessary coordinates are taken by tracing the

  outline of the person on the image reproduced by means of a cursor of the indi-

  31 and, depending on the coordinates taken, the corresponding addresses

  second memory disk 37 corresponding to the scanning lines on the film

  are processed by the operational circuit 32. The addresses ob-

  held are transcribed on the second address memory 37, at the same time

than the number of images.

  The address signals, entered in the second address memory, are

  33, as previously described of the second memory disk 37, are successively

  read for each original image at the same time as the address signals

  registered on the first addressing memory 35 of the first memory disk 36.

  The read address signals are arranged according to the desired reproduction.

  by the operator circuit 34, that is to say the selection or masking by means of a mask is done on request, and the start and end addresses of the

  second memory disk 37, for each image reproduced, are arranged in gold.

  dre scan lines on the recording film. At the same time,

  beginning and end of the first memory disk 36, which correspond to this

  the second memory disk 37, are processed by the operational circuit 34.

  Then, the intermediate addresses, between the start and end addresses, read on the first and second addressing memories 35 and 33 of the first and second memory disks 36 and 37, are processed in the order of the addresses to scan the images. reproduced according to the desired reproduction, and

  the signals are transformed from the first memory disk 36 to the second media disk.

  28, which is synchronous with the rotation of the recording cylinder 21.

  The image signals read in the memory 18 are transmitted to the recording head 26 by means of a switching circuit 19 and the converter

  digital-analog 20, in which they are converted into analog

  cal. By these analog image signals, the recording head 26 is

  in such a way that the reproduced images can be reproduced on the recording film, mounted on a recording cylinder 21 according to the

desired reproduction.

  The recording cylinder 21 is driven by a motor 22 on a rotating shaft. A pulse generator 23, such as a rotary coding device, is integral with the drive shaft and generates the pulses

  transmitted to the timing signal 19. The recording head 26 is disengaged

  places along the axis of the recording cylinder by a threaded rod 25 and

  a motor 24 which drives the threaded rod 25. The position of the recording head

  26 is detected by a pulse generator 27, such as a device

  linear encoder which transmits position signals to the timing circuit

trage 19.

  Although the present invention has been described in connection with a preferred embodiment, various modifications may be made by those skilled in the art without going beyond the scope of the present invention.

  For example, the image scanning means are not necessary-

  limited to three units, but may include a greater number of

29 ments.
