Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film image reading device, and more particularly to a device for photoelectrically reading a recorded image of a developed photographic film held in a holder.

[0002]

2. Description of the Related Art As a conventional film image reading device,
Set the developed photographic film in a state of being held in a holder, and for example, the holder holding the photographic film in a direction (sub scanning direction) orthogonal to the element array direction (main scanning direction) of the line sensor at a constant speed. In some cases, the recorded image on the film can be read two-dimensionally by sending the image (JP-A-62-72267, JP-A-62-189873, JP-A-64-84254, JP-A-64-84254). Japanese Patent Laid-Open No. 64-24690 and Japanese Patent Laid-Open No. 2-10
9036, JP-A-1-290369, etc.). Then, a system has been proposed in which a color printer performs printing based on the image information obtained by the reading, instead of the printing directly exposed from a general photographic film.

Further, in such a reading device, after various corrections and editing processes are performed on the read image information,
Many of them are configured to output to a printer, etc.
In the editing work, image information obtained by roughly reading the film image (rough scan) is used, and when the correction and editing processing conditions are determined, finer reading (fine scan) is performed, and the fine scan is obtained. The image information is corrected and edited again and output to the printer.

[0004]

In the film image reading apparatus as described above, when the photographic film held in the holder is set, it is necessary to read all the photographic films each time, and the recorded image content is read. However, there is a problem in that it takes time to pick up an image to be printed or an image to be edited.

Further, even if the characteristic of the recorded image is detected by rough scanning in the past and the processing condition of the corresponding image is set, it is necessary to make the rough scanning again and determine the processing condition every reading. There was a problem that processing efficiency was poor. Here, we considered storing the image information obtained by the rough scan in the device, but in the device that processes a large number of photographic films, in order to effectively utilize the limited storage capacity, the images that are no longer needed There is a problem in that the work such as erasing information is required and it is complicated.

The present invention has been made in view of the above problems, and in an apparatus for holding a photographic film in a holder for reading, a recorded image of the photographic film held in the holder can be easily confirmed. It is also an object of the present invention to eliminate waste of repeated setting of gradation processing conditions and the like, and to avoid complicated management work of stored contents in a configuration for storing image information.

[0007]

Therefore, a film image reading apparatus according to the present invention is provided with an image reading means for reading an image of a developed photographic film held in a holder by photoelectric conversion by a photoelectric conversion element, and A film image reading apparatus in which reading by the image reading means is switched between a fine mode and a rough mode for performing a rougher reading than the fine mode, wherein a storage medium is integrally provided in the holder, and the image is read at least in the rough mode. The image information read by the reading means is stored in the storage medium.

Here, the holder is composed of a pair of openable and closable frames which sandwich and hold the developed photographic film, and the stored contents of the storage medium are associated with the opening and closing operations of the pair of frames. It is preferable that the data is forcibly erased. Further, in the case of including image processing condition setting means for setting processing conditions of the image information based on the image information read in the rough mode by the image reading means, the image is read in the rough mode with respect to the storage medium of the holder. The processing condition may be stored together with the image information.

Further, it is preferable to provide index display means for reading out the image information stored in the storage medium of the holder and displaying a plurality of the read image information side by side on the display means.

[0010]

According to the film image reading apparatus having such a structure, the storage medium is integrally provided in the holder for holding the photographic film, and the result obtained by rough scanning the image of the photographic film is read by the corresponding storage medium of the holder. Memorized in. Therefore, the image information read out from the storage medium of the holder is a recorded image of the photographic film held in the holder, and the information of the recorded image of the photographic film for each holder is an electric image signal although it is a rough read result. Can be obtained as

In addition, if the memory contents of the storage medium of the holder are forcibly erased with the opening / closing operation of the pair of frame members constituting the holder, when the holder holds another photographic film. It is possible to always match the photographic film held in the holder with the stored content of the storage medium of the holder without special instruction / operation for erasing the stored content.

Further, when the image processing conditions are set based on the image information read in the rough mode, the set image processing conditions are stored together with the image information in the rough mode in the storage medium of the holder. By doing so, it is not necessary to repeatedly set the image processing conditions for the same image. Further, by reading the image information stored in the storage medium of the holder and displaying a plurality of the image information side by side on the display means (index display), the recorded image of the photographic film held in the holder can be easily confirmed. .

In this example, the developed negative film 10 cut into 6 frames is held by the holder 12, and the holder 12 is stored in the cassette 20 at the maximum. Then, the cassette 20 is inserted into the cassette insertion slot 2.

The holder 12 has a lower frame 13 as shown in FIG.
And an upper frame 15 hingedly attached via a shaft 14, and holds the film 10 by sandwiching it between the lower frame 13 and the upper frame 15. The window 16 is formed in the window 16 so as to continuously face the image recording portions of the six frames of the held film. Further, in this embodiment, each holder 12 is integrally provided with a rewritable memory (storage medium) 17 with a backup power source 17a, and access to the memory 17 is formed by projecting on one side surface on the opening / closing side of the holder 12. It can be performed via the terminal 18 which is connected.
A switch 19 for detecting the opening / closing operation of the holder 12 is provided, and the switch 19 allows the pair of frame bodies 13 and 15 to be connected.
A circuit (not shown) for forcibly erasing the stored contents of the memory 17 is detected when the opening / closing operation is detected.
It should be noted that the erasure includes a case where stored data actually remains but is treated as no data.

The cassette 20 is a box body having an open front surface, and holding grooves 21 of seven steps are formed on each of the left and right side plates. Then, guide both ends of the holder 12 to the left and right holding grooves 21,
A maximum of seven holders 12 are housed in a state in which the film surfaces thereof are parallel to each other and are stacked, and each of them can be drawn out in a direction parallel to the film surface. Here, the terminal 18 of the holder 12 housed in the cassette 20 in a state where the cassette 20 is inserted in the cassette receiver 22 connected to the cassette insertion port 2.
The cassette receiver 22 is provided with a terminal (not shown) that is selectively connected to the memory 17 to enable access to the memory 17.

On the other hand, in order to select an arbitrary holder 12 from the cassette 20 in the cassette receiver 22 connected to the cassette insertion port 2 and convey it to the reading position, holder conveying devices 23 are provided on the left and right sides of the cassette receiver 22, respectively. It is provided. The holder transfer device 23 moves up and down by the elevating mechanism to hold the holder 12 by the holding arm 24 to the storage position of the holder 12 to be transferred, and further moves back and forth by the slide mechanism to perform sub-scanning on the holder 12 held by the holding arm 24. Transport on table 25.

The sub-scanning table 25 mounts the holder 12 transported by the holder transporting device 23, and has a hole 26 corresponding to the frame portion of the film. The sub-scanning table 25 is guided by the two guide rails 27 and 28 extending in the direction orthogonal to the carrying direction of the holder carrying device 23,
A belt 30 driven by a drive unit 29 reciprocates.

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 and is applied to the film 10 held by the holder 12. Then, above the sub-scanning table 25,
A CCD line sensor 35 is provided on the optical path of the light transmitted through the film 10 via a reading lens system (including a diaphragm and a filter) 34. The CCD line sensor 35 is
A large number of pixels (photoelectric conversion elements) are arranged in a direction (main scanning direction) orthogonal to the reciprocating direction (sub scanning direction) of the sub scanning table 25, and image information is carried by transmitting the film 10. The illumination light is received, and the image information is converted into an electric image signal by photoelectric conversion.

The reading operation will be described. After the cassette 20 in which the holder 12 is stored is set in the cassette insertion slot 2, the designated holder 12 is transferred to the cassette by the transport device 23.
It is conveyed from 20 onto the sub-scanning table 25. After this, the drive unit 29 moves the sub-scanning table 25 to move the holder.
While sending 12, the signal of the CCD line sensor 35 is read to obtain the image information of all the frames of the holder 12 or the image information of the designated frame. This includes rough scan and fine scan. The rough scan is a mode for reading roughly at high speed (for example, 8 times speed) for index display and the like, and the fine scan is for the printer 7.
For final output to etc., it means a mode to read finely at standard speed slower than rough scan.

Next, the flow of work in the apparatus of this embodiment will be described with reference to the flow chart of FIG. First, in the initial state of image reading, the touch panel 3 displays an operation menu as shown in FIG.
There is no indication on the CRT. Where the cassette
When 20 is set and the film 10 is read, "FILM" on the touch panel 3 shown in FIG.
By selecting "FILM" among the selection buttons of "REFLEX" by touch operation and further touching "START", reading of the film image is started.

The initial reading is performed in the rough scan mode, and all the holders 12 (or only the designated holders 12) housed in the cassette 20 are successively conveyed to the sub-scanning table 25 to be read. The images of all the frames of the holder 12 are read roughly at high speed. The rough scan is performed twice for each holder 12, and the first one is called a pre-scan and the second one is called an index scan. That is, the image data is obtained by the prescan at 8 times speed for the first time (S1), and the data showing the image characteristics is extracted from the histogram (or cumulative histogram) information created based on this (S2). Then, correction data (conversion table for gradation conversion, color balance processing, etc.) is created based on the image characteristic data (S3), and the correction data is corrected again by the second 8-times speed index scan (S4). The image data (S5) is obtained. The image data obtained by the rough scan (index scan) is stored in the frame memory and used for editing and displaying.

Here, the frame position (image recording area) is detected based on the image data obtained by the first pre-scan of the rough scan. That is, since the recorded images of 6 frames are continuously read including the interval portion, the interval portion is detected as the portion having the maximum light amount from the change in the signal level in the sub-scanning direction in the reading result ( (See FIG. 6), only the actual image recording portion is extracted from the data obtained by continuously reading 6 frames, and this is used for display, and correction data is created from the extracted image data. .

The detection of the frame position is unnecessary if the film 10 is set by aligning the frame position with respect to the holder 12 and the film is fed from the starting end of the holder 12 at a predetermined frame pitch. Since it is assumed that the pitch accuracy is poor, the position of the DX code (see FIGS. 7A and 7B) recorded on the side edge of the film for each holder 12 is detected from the starting end of the holder 12. At the same time, it is preferable to store the frame position information in the image data together with the positional deviation amount of the screen frame detected from the change in the light amount in the interval portion of the frame.

At the time of the pre-scan and the index scan, a display indicating that the reading operation is being performed is displayed on the touch panel 3, and the read images are arranged side by side for each holder 12 and sequentially displayed as an index. FIG. 8 is a diagram showing a display state during the prescan, in which the touch panel 3 indicates that the prescan is being performed, and the operation menu is not displayed. Further, on the first CRT 3, the images are sequentially displayed side by side every time the images are read. The image surrounded by double lines in FIG. 8 indicates the latest read image.

FIG. 9 is a diagram showing a display state during the index scan. It is displayed on the touch panel 3 that the index scan is in progress, and
In the CRT 3, the images displayed by the prescan are rewritten one after another by the images obtained by the index scan. When the index scan is completed, all the read images are displayed as indexes on the first CRT as shown in FIG. 10, and the touch panel 3 is displayed to inform that the reading of the input image is completed.

When the rough scan of all the holders 12 is completed, the processing menu is displayed on the touch panel 3 this time,
By touching the display menu portion, instructions for correction processing such as color conversion and editing processing such as image composition are given, and the result of processing the image data obtained by the hula scan according to the instructions is displayed on the second CRT 5 (S8). ). And the correction,
When the edit processing conditions are determined and the output image displayed on the second CRT 5 is desired to be printed, the holder 12 corresponding to the frame for which output is instructed is again conveyed to the sub-scanning table 25, and fine scanning at standard speed is performed this time. The image data obtained by the fine scan is subjected to the determined correction and editing processing (S9) and output to the printer 7 (S10).

FIG. 11 is a diagram showing a display state during fine scanning when index printing is performed.
Images finely read by the fine scan are displayed one after another on the second CRT 5 side. Here, in this embodiment, when the holder 12 after the rough scan is returned to the cassette 20, the image data obtained by the rough scan with respect to the memory 17 via the terminal 18, the gradation conversion and the color conversion. The correction data (conversion table), frame position information, and aperture value at the time of reading are stored.
The data stored in the memory 17 requires image information by rough scan, but is not limited to the above, and various detection conditions based on reading conditions in rough scan or image information obtained by rough scan. The data (type of film, etc.) can be stored.

The holder 12 in which the data is stored in the memory 17 as described above is separately provided in the film reading apparatus 1 of this embodiment.
When set to, the data stored in the memory 17 may be read out instead of performing the above rough scan. Therefore, before carrying the holder 12 to the sub-scanning table 25 to perform the pre-scan, the memory 17
Whether data is stored in the memory via the terminal 18
Check by visiting 17. Then, while the holder 12 having no data stored therein is normally rough-scanned, the holder 12 having the memory 17 having data stored therein is not read by rough-scanning, and the memory 17 of the memory 17 is supplied via the terminal 18. Read the stored data,
The read-out image data, conversion table, aperture value, frame position information, etc. are directly treated as normal rough scan data.

That is, when the negative film 10 is held in the holder 12 for reading for the first time, no data is stored in the memory 17 of the holder 12 by the erasing function described above. However, when the rough scan is instructed again with respect to the holder 12, the reading is not actually performed and the data stored in the memory 17 is read out, and the image data is displayed on the first CRT. Display the index.

Therefore, the holder 12 once rough-scanned
2), the second rough scan (pre-scan and index scan) is unnecessary (S1 to S5 in FIG. 4).
Processing is omitted), and the recorded image is processed in the first CR at high speed.
The index can be displayed on the T, and the cassette 20
The image content of the film 10 held in the holder 12 accommodated in the can be confirmed easily and quickly.

Further, since the image processing conditions which are usually calculated based on the image data obtained by the rough scan are also stored in the memory 17, it is not necessary to repeat the same calculation again, and from this point as well, the efficiency is improved. Good processing becomes possible. Further, since the memory 17 of the holder 12 is configured to be forcibly erased with the opening / closing operation of the holder 12, it is not necessary to instruct each time to erase the data of the film 10 that has been processed, and , The film stored in memory 17 is stored in memory 17
It does not stop responding to.

In the above embodiment, the holder 12 holds the negative film 10 cut into six frames, but as shown in FIG. 12, for example, a film winding mechanism is provided,
It may be a holder configured to hold the developed long film by locking it to the winding mechanism. Figure 12 above
The holder shown in (1) has a mechanism similar to that of a normal photographic camera. An upper frame 51 corresponding to the back cover of the camera and a lower frame 53 provided with a winding mechanism 52 are arranged at one end side in the longitudinal direction. Is attached in a hinged manner with the shaft as an axis, and like the holder 12, the upper frame 51 and the lower frame 53 each have a window 54 for one frame facing the film, and the upper frame 51 A memory 55 is provided on the inner side. Access to the memory 55 is performed through a terminal (not shown) provided on the lower frame 53 side, but in order to electrically connect the lower frame 53 side terminal and the upper frame side memory 55, an opening / closing shaft is used. The part of is connected by a flexible wire 56.
