Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film image editing apparatus for reading and editing a plurality of images photographed on a developed photographic film.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Examined Patent Publication No. 21383/1992, a plurality of images are input, edited according to a predetermined layout, and output.

[0003]

However, this is one for inputting an image (original) from an input drum and outputting an edited image, and reading the image photographed from the developed photographic film. Since it is not based on the assumption that images shot on photographic film will have normal screen size (full size), landscape size such as panorama size,
Since there are multiple types of screen sizes such as half size, it was difficult to apply.

Particularly, in recent years, panorama size photographs using the most common 35 mm film as photographic film have become popular. This panoramic size is a 35mm film with a normal screen size (full size; 24mm x 36mm) shielded from above and below to a landscape screen size (13mm x 36mm). High-definition size TVs with aspect ratios of 9:16 are also appearing. In the case of a full size L size print, the photographic paper size is 89 mm x 127 mm, but the panoramic size photographic paper size is 89 mm x 254 mm, and the high definition size photographic paper size is 89 mm x 158 mm.

There are also cases where half-size shooting is performed in which two screens are recorded within a full-size screen. In this way, even with the same 35mm film, the screen size can be full size, landscape size (panorama size, high definition size), half size, etc. In addition, recently, it is usually in the middle of shooting one film. Cameras that can arbitrarily switch between shooting (full-size shooting) and panoramic shooting have been commercialized, and films that have screens of different sizes have come to appear.

Therefore, when the image photographed on the developed photographic film is read and edited, it is necessary to detect the screen size and perform image processing according to the screen size when reading the image information. Has become. Also,
Since the editing device of the publication only outputs the edited image to the display, it is impossible to see the input image actually read during editing. Therefore, the input images are sorted in advance and the configuration is considered. Since it is necessary to perform the work in advance, and the work requires skill and becomes specialized, it has been desired to facilitate the editing work.

In addition, when editing, color correction of an image may be performed. In Japanese Patent Laid-Open No. 62-272755, color correction is performed in units of screens by cursor input on a color chart, while in units of screens. The above point is designated so that the color before and after the correction for the designated point is displayed so that the suitability of the correction can be determined.

However, even in such color correction, it depends on the intuition of the operator as to how much the correction amount should actually be set, and the work of changing the correction amount by seeing the corrected color If you repeat Therefore, it is difficult and troublesome to finish the color correction with one operation. On the other hand, the request for color correction is set to some extent, such as accurately displaying the color of human skin, the blueness of the sky, the green of the forest, etc. on the image, so that the color correction can be done easily. It was desired to do.

In view of the above situation, the present invention accurately reads and edits an image taken on a photographic film even when the photographic film has different screen sizes or when different screen sizes are mixed on the same photographic film. An object of the present invention is to provide a film image editing apparatus capable of performing the above. In addition, the present invention, in such a film image editing apparatus,
To facilitate the editing work by allowing the operator to actually check and confirm multiple images read from the developed photographic film before editing. (Correction) and layout editing are intended to be easier to perform.

[0010]

Therefore, the film image editing apparatus according to the present invention, as shown in FIG. 1, is an image information reading means for reading image information from a developed photographic film for each screen of a predetermined screen size.

When the density change pattern is detected in the predetermined width area which is the non-image recording area in the specific screen size as described above, the density change detecting means detects the image information read by the image information reading means. It is preferable to have a binarizing unit for binarizing and detecting the pattern of density change based on the binarized data. Further, the editing means (C) has display means for displaying a plurality of images indexed from the image information read by the image information reading means and the screen size detected by the screen size detecting means. It is good to have

Further, the editing means (C) corrects an image from a plurality of images determined from the image information read by the image information reading means and the screen size detected by the screen size detecting means. It is preferable to have a correction image selecting means for selecting, and a correction means for correcting the image selected thereby according to a correction instruction input. The correction means here is a color correction area designating means for designating an area on the original image for color correction, and a target color selecting means for selecting a target color for color correction from a plurality of preset target colors. And a color conversion unit that performs color conversion of the image so as to match the designated area with the selected target color.

Further, the editing means (C) edits an image from a plurality of images determined from the image information read by the image information reading means and the screen size detected by the screen size detecting means. It is preferable to have edit image selecting means for selecting the item and layout editing means for editing the image selected thereby according to a predetermined layout.

[0016]

In the above construction, first, the image information reading means (A) reads image information from the developed photographic film for each screen of a predetermined screen size (normal screen size; full size). Specifically, the developed photographic film is scanned by the line sensor in the main scanning direction and the sub scanning direction, and the image information recorded on the photographic film is two-dimensionally read.

Next, the screen size detection means (B)
The screen size of each image is detected from the density change information on each read screen based on the image information read by the image information reading means. Specifically, based on the read image information, a pattern of density change in a predetermined direction on each read screen is detected. Then, the detected density change pattern is compared with the reference pattern corresponding to the unique density change pattern for each screen size, and the screen size of each image is determined based on the matching relationship between them.

Here, the detection of the pattern of the density change is performed in a horizontally long size (panorama size,
It may be performed in the longitudinal direction of a predetermined width area which is a non-image recording area in the case of high-definition size) or half size, and whether the pattern of density change in such an area corresponds to the horizontally long size or half size non-image recording area. The full size, the horizontally long size, and the half size can be discriminated depending on whether or not.

Further, the density change pattern only needs to be able to distinguish between the image recording area and the non-image recording area, so that the read image information can be distinguished into the image recording area and the non-image recording area based on the reference level. It may be binarized and the pattern of density change may be detected based on the binarized data. Next, the editing means (C) edits the image determined from the image information read by the image information reading means and the screen size detected by the screen size detecting means in accordance with an external editing instruction input.

In this editing, if a display means for displaying a plurality of images before editing is provided as an index, the operator can see and select these images and perform editing work including correction, and the index display Since the editing is performed while viewing the image by, the work is easy and efficient. It is also possible to arbitrarily select from a plurality of images before editing to correct the image.For color correction, in particular, while specifying the area on the original image to be corrected, If the target color is selected from a plurality of preset target colors, the color conversion of the image is performed so as to match the designated area with the selected target color. That is, by setting in advance a target color that is often desired to be output as a desired color (for example, skin color, blue, green, etc.), the target color can be selected and corrected on the original image for color correction. If the portion to be colored is designated, the color conversion of the portion is performed, and the desired color correction can be performed with one operation.

Further, in editing, a plurality of images before editing are selected, and the selected image is edited according to a predetermined layout. Therefore, if a plurality of layouts are set in advance and selectable, the layout can be changed. Editing can be done easily. Finally, the output means (D) outputs the image edited by the editing means.

EXAMPLES Examples of the present invention will be described below. FIG. 2 is an external view of the film image editing apparatus. A cassette insertion opening 2 for film reading and a liquid crystal touch panel (LCD) 3 for operation are provided on the table of the image editing apparatus main body 1 including the film reading apparatus. Further, a first CRT 4 for displaying an input image and a second CRT 5 for displaying an output image are provided side by side. A printer 7 having a scanner 6 for reading a reflection original can be connected to the image editing apparatus main body 1.

FIG. 3 is a structural diagram of the film reading device portion. In this example, a continuous developed photographic film (negative film) 10 of 6 frames each is held in a film holder 12, and a maximum of 7 film holders 12 are stored in a cassette 20. Then, the cassette 20 is inserted into the cassette insertion slot 2. As shown in FIG. 4, the film holder 12 has a lower frame 13 and an upper frame 15 hingedly attached via a shaft 14 so that the photographic film 10 is placed between the lower frame 13 and the upper frame 15. And hold it. Of course, the lower frame 13 and the upper frame 15 are formed with windows 16 for the number of frames (six) of the photographic film 10.

The cassette 20 is a box body having an open front surface, and holding grooves 21 are formed in seven steps on the left and right side plates, respectively. Then, the both ends of the film holder 12 are connected to the left and right holding grooves 21, 21.
7 film holders 12 are housed in a state in which the film surfaces of the film holders 12 are parallel to each other and stacked, and each of them can be drawn out in the direction parallel to the film surface.

In this example, the film holder 12 for the negative film is stored in the cassette 20, which is 6 frames × 7.
The holder can store a maximum of 42 frames, but if you use a positive film film holder that holds 5 positive films of each frame side by side for a positive film, 5 frames x 7 holders can store a maximum of 35 frames. it can. Of course, the film holder for the negative film and the film holder for the positive film may be mixed and stored.

A cassette receiver 22 connected to the cassette insertion slot 2
In order to select an arbitrary film holder 12 from the inside cassette 20 and convey it to the reading position, film holder conveying devices 23, 23 are provided on the left and right sides of the cassette receiver 22, respectively. The film holder transport device 23 is moved up and down by the elevating mechanism to the storage position of the film holder 12 to be transported, holds the film holder 12 by the holding arm 24, and is further moved back and forth by the slide mechanism to be held by the holding arm 24. 12 is conveyed onto the sub-scanning table 25.

The sub-scanning table 25 mounts the film holder 12 conveyed by the film holder conveying device 23, and has a hole 26 in the frame portion of the film. And
The sub-scanning table 25 includes two guide rails 27 and 28 extending in a direction orthogonal to the transport direction of the film holder transport device 23.
The belt 30 driven by the stepping motor in the drive unit 29 is reciprocated.

Below the sub-scanning table 25, a lamp 31,
A condenser mirror 32 and a condenser lens 33 are provided, and the light of the lamp 31 is collected by the condenser mirror 32 and the condenser lens 33 so that the photographic film 10 held by the film holder 12 is irradiated with the light. There is. Then, the sub scanning table 25
Above the optical path of the light that has passed through the photographic film 10,
A CCD line sensor 35 for color is provided via a reading lens system (including a diaphragm and a filter) 34. CCD
The line sensor 35 has a large number of pixels (photoelectric conversion elements) arranged in a direction (main scanning direction) orthogonal to the reciprocating direction of the sub scanning table 25 (sub scanning direction).

The reading operation will be explained. After the cassette 20 in which the film holder 12 is stored is set in the cassette insertion slot 2, the designated film holder 12 is conveyed.
It is conveyed from the cassette 20 onto the sub-scanning table 25 by 23. After that, the sub-scanning table 25 is moved by the drive unit 29, the signal of the CCD line sensor 35 is read while feeding the film holder 12, and the image information of all the frames of the film holder 12 or the image information of the designated frame is read. To get

Here, an origin marker (not shown) is provided on the sub-scanning table 25, and the origin position can be detected by detecting this with a photo sensor (not shown) fixedly arranged, and the drive unit from this origin position can be detected. By reading according to the driving amount of 29 (rotation amount of the stepping motor), reading can be performed for each frame, that is, for each screen of the normal screen size (full size).

When the reading is completed, the driving unit 29 moves the sub-scanning table 25 in the opposite direction to return it to the initial position. Then, the film holder 12 on the sub-scanning table 25
Is returned to the original position of the cassette 20 again by the transport device 23.
The reading of image information from the developed photographic film 10 includes rough scan and fine scan.

The rough scan is to read the images of all the frames in a high speed (for example, 8 × speed) mode, that is, to reduce the number of read pixels and to roughly read the images for screen size detection and index display prior to editing. . For example, in the case of 8 times speed, the number of read pixels is reduced to 1/8 (total 1/64) in each of the main scanning direction and the sub scanning direction. At this time, the plurality of film holders 12 in the cassette 20 are successively conveyed onto the sub-scanning table 25, and the images of all the frames are roughly read from all the film holders 12 at 8 times speed. This rough scan is performed twice for each film holder 12, and the first one is called a prescan and the second one is called an index scan. That is, the image data is obtained by prescanning at 8 × speed for the first time, and the reading condition in which the gradation balance is corrected based on the image data is set. Based on this, the image data is obtained while correcting the image.

The fine scan means to read the image of the selected frame in the normal mode, that is, without reducing the number of read pixels, for the final output to the printer 7 etc. after editing. At this time, cassette 20
The film holder 12 including the frame selected from the inside is conveyed onto the sub-scanning table 25, and the image of the frame selected from the film holder 12 is read at the standard speed. Also during this reading, correction is made under the reading conditions set based on the data obtained by the above-described prescan.

FIG. 5 is a block diagram showing a circuit configuration of the film reading device. CCD line sensor for color
The analog image signal for each of the three primary colors (R, G, B) output from 35 is input to the A / D converter 42 via the sample hold circuit 41, and the A / D converter 42 outputs the three primary colors for each of the three primary colors. It is converted into a digital image signal. Here, the CPU 43 is shown in FIG.
It has a function to control the reading operation of the mechanical part, and is connected to the actuators and sensors of the mechanical part shown in (1), and the data reading mode mainly includes the normal mode for reading image data of all pixels and the number of read pixels. It has a function of instructing the control circuit 44 which one of the 8 × speed mode in which the scanning direction and the sub-scanning direction are respectively reduced to ⅛.
The control circuit 44 receives the normal / 8 × speed switching signal,
C based on a reference clock signal from an oscillator (not shown)
In synchronization with the data clock or line reset signal in the drive circuit 45 that drives the CD line sensor 35, the sample hold circuit 41 and the A /
The D converter 42 is controlled to switch between fine scan and rough scan. In the normal or 8 × speed mode, A / D conversion is performed at the timing shown in FIG.

The shading correction circuit 46 performs shading correction on the digital image signal output from the A / D converter 42. In the first rough scan (pre-scan), data is read for setting correction conditions such as color, and in the second rough scan (index scan) or fine scan, the correction conditions set based on the scan are used. Is corrected and stored in the frame memory at the subsequent stage.

By the way, the photographic film 10 to be read
As shown in FIG. 7, a panorama size screen shot with the upper and lower sides of a normal full size screen shot, and a half size screen that divides a normal full size screen into two screens It is a film mixed with a screen, and in order to perform image processing for editing based on the image signal read from the photographic film 10, it is necessary to identify the screen size.

Therefore, in order to identify the screen size, A /
The digital image signal after A / D conversion by the D converter 42 is temporarily stored in the memory 47, and the screen size is automatically identified based on the stored data. Here, the CPU 43 has a function of controlling writing of a digital image signal to the memory 47 via the control circuit 44.
Then, based on the digital image signal stored in the memory 47, the screen size is identified as described later, and the identification result is output to the image processing circuit for editing in the subsequent stage via the I / O interface 48. It has become.

Next, how the CPU 43 detects the screen size will be described. First, the basic characteristics of screen size detection will be described. As shown in FIG. 7, the photographic film 10 to be read has a full-size screen, a panoramic size screen, and a half-size screen mixed, but the panorama size (or high-definition size) that is horizontally long with respect to the full size. ) Indicates that the full-size screen is narrowed up and down by having a non-image recording area (light-shielding area) of a predetermined width above and below the full-size screen (up and down in the width direction of the film). A non-image recording area of a predetermined width extending vertically (in the film width direction) is provided at the center of the full-size screen, and the non-image recording area divides the full-size screen into two image recording areas.

Therefore, if the non-image recording area (light-shielding area) in the full-size screen can be discriminated based on the image signal read as the full-size screen, the full size, panorama size and half size can be distinguished. For example, the lower and upper areas that are non-image recording areas in the panorama size are set as determination areas t1 and t2, respectively (see FIG. 8), and the longitudinal direction in this area (in the sub-scanning direction in this embodiment) Yes, the change in the density (transmittance) in the film frame feed direction) is detected.

Here, if the read screen has a panoramic size, both the judgment areas t1 and t2 are non-image recording areas, and therefore the base density (minimum density) showing the maximum transmittance.
It remains constant and does not change (see FIG. 9A). If the size is full, the determination area t1,
Since the image is also recorded at t2, the density changes randomly at a density higher than the base density (lower than the maximum transmittance) (see FIG. 9C). Since the non-image recording area exists in the center in the direction of detecting the density change, the central portion shows the maximum transmittance corresponding to the base density (minimum density) (see FIG. 9B). .

Further, an area which becomes a non-image recording area for the full-size screen in the case of half size is defined as a judgment area uφ (see FIG. 8), and a longitudinal direction in the judgment area uφ (in the main scanning direction in this embodiment). Yes, it corresponds to the width direction of the film). In this case, in the case of the panorama size, since there are non-image recording areas of a predetermined width on the start point side and the end point side in the density detection direction, respectively, the start point side and the end point side correspond to the non-image recording areas with predetermined widths. The maximum transmittance (minimum density) is shown, and a relatively high density corresponding to image recording is shown between them (see FIG. 10 (a)). If the size is half, the determination area uφ
Is the same as the non-image recording area, so it is constant at the base density (minimum density) showing the maximum transmittance (see FIG. 10B).
Further, in the case of the full size, since the image recording area is from the start point to the end point, the density is higher than the minimum density (see FIG. 10C).

In this way, the area which becomes the non-image recording area (light-shielding area) in the panorama size or half size with respect to the full-size screen is set as the judgment area, and the pattern of density change in the longitudinal direction of the judgment area is detected. , The screen size (full size, panorama size, half size) is determined based on the image signal read as a full size screen by determining the match between the detected pattern and a pattern (reference pattern) peculiar to each screen. Can be detected.

According to the basic characteristics described above, the CPU 43 detects the screen size based on the digital image signal in the memory 47. The digital image signal stored in the memory 47 is data used only for screen size detection. Therefore, the rough scan data of 8 times speed is used. Also memory
The image signal of the entire area of the full-size screen may be stored in the 47, but as described above, what is required for the screen size detection is the non-image when the panorama size or half size is set in the full-size screen. Since only the image signal of the determination area which is the recording area (light-shielded area) is used, C
The PU 43 can instruct the control circuit 44 whether to store the entire area in the memory 47 (entire reading mode) or only the image signal in the determination area (partial reading mode). Therefore, the control circuit 44 can output the write clock as shown in FIG. 11 or 12 to the memory 47 according to the instruction of the storage area from the CPU 43.

Next, the processing contents of the screen size detection in the CPU 43 will be described with reference to the flowcharts of FIGS. 13 and 14. The flowcharts of FIGS. 13 and 14 correspond to the screen size detecting means. The flowchart of FIG. 13 shows the overall flow of screen size detection. In step 1 (denoted as S1 in the figure; the same applies hereinafter), the control circuit 44 is set to the 8 × speed mode.

Next, in step 2, it is judged which of the whole reading mode and the partial reading mode is selected, and the process proceeds to step 3 or step 4 depending on the judgment result, and the control circuit 44 is set to each mode. It is set and set so that the entire image signal or the image signal of only the determination region is stored in the memory 47 at 8 times speed. In step 5, the writing of the digital image signal to the memory 47 is actually started, and the writing in the memory 47 is continued until the completion of writing is determined in the next step 6.

When the writing of the image signal to the memory 47 is completed, in step 7, a density change pattern in a predetermined direction of the screen is detected based on the data stored in the memory 47, and the density change pattern and each screen size are unique. The screen size is detected by comparison with the reference pattern of. Then, in the next step 8, the detected screen size is output to and stored in the image processing circuit for editing in the subsequent stage.

The flow chart of FIG. 14 shows the details of the screen size detection of step 7 in the flow chart of FIG. In step 11, each judgment area t
The image signals at 1, t2 and uφ (see FIG. 8) are averaged in the width direction, and the pattern of density change in the longitudinal direction of each determination region is detected based on the average value. The averaging process may be performed not only in the width direction but also in the direction in which the density change pattern is obtained.

In the next step 12, the digital image signal subjected to the averaging process is binarized. The threshold level in the binarization is set to an intermediate value between the base density of the photographic film 1 (density corresponding to the non-image recording area) and the maximum density in the image recording area. ) And a density level corresponding to the maximum density of the image recording area are binarized (FIG. 15).
~ See Figure 19).

The threshold level may be variably set based on the detection result by detecting the base density (transmittance of the base portion) for each photographic film. In step 13, a pattern of density change in the sub-scanning direction (density change of 2 Pattern represented by a value)
, It is determined whether or not they both coincide with the reference pattern of the panoramic size that is constant at the maximum transmittance (corresponding to the base portion) as shown in FIG.

If the read screen is a panoramic size, the upper and lower judgment areas t1 and t2 in the film width direction are both light-shielding areas and image recording is not performed. Therefore, as shown in FIG. Should show a density change peculiar to the panorama that becomes constant at the maximum transmittance. In this case, the process proceeds to step 14 and the read image is identified as the panorama size.

On the other hand, if the density change pattern in the judgment areas t1 and t2 does not show a constant density change at the maximum transmittance as shown in FIG. 15A, the process proceeds to step 15. In step 15, in order to distinguish between the full size and the half size, the density change patterns detected in the upper and lower determination areas t1 and t2, which are the non-image recording areas in the panorama size, are shown in FIG. (A)
As shown in, it is determined whether or not only the central portion of the screen has a pattern (half-size reference pattern) indicating the non-image recording area.

Here, if it matches the half-size reference pattern, the process proceeds to step 16 to identify that it is the half-size, and if it does not match the half-size reference pattern, the remaining full-size is used. Go to step 17 to determine if there is. In step 17, the density change patterns detected in the determination areas t1 and t2 respectively correspond to the case where image recording is performed.
It is determined whether or not the pattern (a full-size reference pattern) shown in FIG.
If all the density change patterns in 2 indicate continuous image recording, the process proceeds to step 18 and it is identified that it is a full size.

On the other hand, when it is determined in step 17 that the density change pattern does not match the full-size density change pattern, the screen size is unknown according to the strict criteria. However, when the full size is switched to the panorama size, the date may be imprinted on the lower determination area t1 which is not the image recording area in the panorama size. The judgment cannot identify the panorama size.

Therefore, when it is determined in step 17 that the size is not full size, the process proceeds to step 19, and in the upper determination area t2, the density change in the sub-scanning direction (longitudinal direction of the determination area) is a panoramic pattern (see FIG. 15 (a)), but the pattern of density change in the lower determination area t1 is almost a non-image recording area but partially shows an image recording area as shown in FIG. 18 (a). If the pattern is a pattern that appears, the portion corresponding to the image recording is estimated to be noise due to imprinting of the date, and the process proceeds to step 20 for further confirmation.

In step 20, the non-image recording area in the half size extending vertically in the center of the screen is set as the judgment area uφ, and the pattern of density change in the longitudinal direction of the judgment area uφ (corresponding to the main scanning direction) is detected. , This is Figure 19
It is determined whether or not the top and bottom as shown in (a) coincide with the reference pattern of the panorama size which is the non-image recording area.
Here, in the determination area uφ that extends vertically in the center of the screen,
When the density change pattern peculiar to the panorama size shown in (a) is shown, it is considered that the estimation of the noise occurrence was correct, and the process proceeds to step 14 to specify the panorama size.

On the other hand, in step 19 and step 20,
If it is confirmed that the size is not the panorama size even if the imprinting of the date is taken into consideration, the process proceeds to step 21 and the screen size is processed as unknown. If the screen size is unknown, all may be processed as a full size screen. The step 11 in FIG. 14 corresponds to the density change detecting means, the step 12 corresponds to the binarizing means, and the steps 13 to 21 correspond to the screen size determining means.

Further, in the screen size detection shown in the flowchart of FIG. 14, the judgment areas t1 and t2 and the judgment area uφ are used, but only one of the judgment areas t1 and t2 and the judgment area uφ is set as the judgment area. You may use. Next, the flow of editing work in this film image editing apparatus is shown in FIG.
~ It demonstrates with reference to the flowchart of FIG. 24 and the display example of FIGS. 25 to 31, the screen of the liquid crystal touch panel 3 is shown in the "LCD" column, and "CRT" is displayed.
In the "1" column, the screen of the first CRT 4 is shown, and "CRT 2"
In the column of, the screen of the second CRT 5 is shown.

FIG. 20 is a flowchart showing the overall flow of editing work. When the film image editing apparatus is activated, a cassette insertion instruction is given on the touch panel screen, and reading from the cassette is started by operating the start button after insertion (step 101 in FIG. 20). At this time, the plurality of film holders 12 in the cassette 20 are successively conveyed onto the sub-scanning table 25, and the images of all the frames are roughly read from all the film holders 12 at high speed (rough scan).

This rough scan is performed twice for each film holder 12, and the first one is called a prescan and the second one is called an index scan. Ie 1
The 8th speed prescan is used to obtain the image data, the correction data is created based on this, and the 8th speed index scan is used to correct the correction data to obtain the image data, which is stored in the frame memory. Remember.

In this way, a maximum of 6 frames × 7 holders =
An image of 42 frames (frames) is read and displayed as an index on the first CRT as shown in FIG. 25 (step 102 in FIG. 20).
