The film player 1 includes a piece film insertion opening 8 for inserting a piece film on its side surface, and a feed roller 10 for conveying the inserted piece film to an image pickup position. At the center of the film player 1, a gear 11 for driving the film stored in the cartridge and a photo interrupter 7 for the cartridge for positioning the film stored in the cartridge are provided. The feed roller 10 and the gear 11 are driven by the motor 9.

The lid 2 is provided with a pair of guide grooves 3 for guiding the piece film to a predetermined image pickup position and one guide groove 3, and a magnetic head for reading magnetic information recorded on the film. 4 and a light source 5 used when capturing an image recorded on the film. A photo interrupter 6 for positioning the piece film is provided at one end of the guide groove 3.

FIG. 2 is a perspective view when the cartridge 12 is loaded in the film player 1. The film feeding gear (not shown) provided on the cartridge is configured to mesh with the gear 11A of the film player 1 and the film winding gear with the gear 11B of the film player 1.

By driving the motor 9 in this state, the gears 11A, 11 provided on the film player 1 are driven.
The film feeding gear and the film winding gear provided on the cartridge are driven via B, and the cartridge 12
The film inside is transported.

FIG. 3 is a diagram when the piece film 13 is inserted into the film player 1, and corresponds to FIG. 2 when the cartridge is loaded.

Referring to FIG. 3, the piece film 13 is inserted from the piece film insertion opening 8 of the film player 1, passes through the guide groove 3 and is fed to a predetermined reproduction position by the feed roller 10. At this time, the peace film 13
The magnetic information recorded in 1 is read by the magnetic head 4. When the piece film 13 is correctly inserted, the information read from the magnetic head 4 is the information recorded by the camera at the time of shooting. However, if it is inserted in the wrong direction (including up and down and left and right), the data for developing the film or not the data recorded by the camera can be read or not read at all. In such a case, the feed roller 10 is rotated in the reverse direction, and the film 13 is ejected or a warning is given. This will be described later.

FIGS. 4A, 4B and 4C respectively show IVA, IVB and IV in FIGS. 2 and 3, respectively.
It is a figure corresponding to the part shown by C. Referring to (A),
The image radiated by the light source 5 is reflected by the mirror 14, the imaging lens 15, and the scanning mirror 16 by the line sensor (C
The image is formed on the CD) 17. The signal from the CCD 17 is processed by the signal processing circuit 18.

FIG. 4B is a diagram showing the transport path of the piece film 13 when the piece film 13 is imaged, and FIG. 4C is a diagram showing a state when the cartridge film is imaged. Referring to (B) and (C),
In both cases, when the cartridge 12 is inserted so that both films are imaged at the same position, the piece film guide groove 3 for conveying the piece film 13 is biased toward the inside of the lid 2 by the spring, 12
When is loaded, the guide groove 3 is partially retracted in the lid 2.

FIG. 5 is a diagram showing details of a portion where the image on the film shown in FIG. 4A is read by the CCD. Figure 5
Referring to, the scanning mirror 16 is rotatable in the direction indicated by the arrow, and when the scanning mirror 16 is in the broken line state, the portion A of the film 20 is imaged on the CCD. When the scanning mirror 16 rotates to the state shown by the solid line, the portion B of the film 20 is imaged on the CCD 17. In this way, the arrows A to C of the film 20 are sequentially imaged on the CCD 17 and photoelectrically converted. A part of the light incident on the CCD 17 is detected by the photometric sensor 21, and the diaphragm 22 is adjusted according to the amount of light received by the photometric sensor 21. Further, the converter lens 23 is inserted in the optical path during zooming.

Next, details of the scanning mirror 16 will be described. The circle in the right side of FIG. 5 is a diagram showing details of the scanning mirror 16. Referring to this figure, the scanning mirror 16 includes a worm gear 28 driven by a motor 27 and a wheel gear 29 engaged with the worm gear 28.
And a bevel gear 26 having a worm gear 30 engaged with the bevel gear 25, and a mirror 32 fixed to a wheel gear 31 engaged with the worm gear 30.

Notches are provided in the bevel gear 25 and the bevel gear 26, respectively. The bevel gear 26 is biased in one direction by a spring.

The mirror 32 includes a bevel gear 25 and a bevel gear 26.
It is kept in the initial position by fitting the notch. When the motor 27 is rotated, the bevel gear 25 is rotated via the worm gear 28 and the wheel gear 29. As a result, the bevel gear 26 is rotated, and accordingly, the worm gear 30 and the wheel gear 31 are rotated, and as a result, the mirror 32 is rotated. When the notches of the bevel gear 25 and the bevel gear 26 mesh again, the rotation is stopped and the mirror 32 returns to the initial position again by the spring. By repeating such operations, the CCD 17 scans the entire area of the film 20 that intersects in the transport direction.

FIG. 6 is a block diagram showing the main part of the control section of the film player according to the present invention.

Referring to FIG. 6, a CPU 40 for controlling the entire film player reads magnetic information on the film in response to a read timing signal from the CPU and outputs the data as digital information to the CPU. The part 41 is connected. The magnetic reading unit 41 has a magnetic head for reading magnetic information on the film, an amplifier for amplifying the magnetic head, and a recording function, and sends the presence or absence of the magnetic information on the film to the CPU 40.

The CPU 40 is connected to a film feeding control section 42 having film advance, return and positioning functions. The presence or absence of perforation provided on the film is detected, and if there is no perforation, a warning signal is issued to the CPU 40.

The lens switching unit 43 switches the magnification of the image pickup lens in response to the switching signal from the CPU 40.

The CCD scanning unit 44 includes the CPU 4
CC in response to a scanning timing signal from 0
The imaging scanning by D17 is controlled.

The aperture control unit 45 responds to the aperture control signal from the CPU 40 and controls the aperture for image exposure control (see FIG. 5).
The aperture 22) of the above is controlled. The CPU 40 uses the photometric data from the photometric sensor 21 as described above with reference to FIG. 5 to obtain the aperture control signal. That is, CPU4
When 0, the aperture value is calculated so as to obtain an appropriate exposure at the time of image capturing, and the aperture control 45 is fed back based on the signal.

The CPU 40 controls turning on and off of the image pickup light source 5, and gives an image pickup timing signal to the CCD 17 for image pickup. The image signal picked up by the CCD 17 is stored in the image pickup data memory 45.

The CPU 40 is further connected to a video processing unit 48 which processes the image data stored in the image pickup data memory 45 and outputs it as a video signal to the television apparatus.

An audio output unit 46 is further connected to the CPU 40, and the audio output unit 46 D / A converts the audio data from the ROM 47 and outputs it as an audio signal to the television apparatus. The ROM 47 is a memory that stores audio data, and responds to an addressing signal from the CPU 40 and outputs corresponding data to the audio output unit 46.
Output to.

The CPU 40 has a manual operation switch 49.
By connecting the control switch 49, the image on the film can be rotated vertically or horizontally, zoomed, panned to move the image horizontally, or tilted to move the image vertically. Performs, pauses, and autostarts the device itself.

Next, the operation of the film player 1 according to the present invention will be described with reference to the flow charts shown in FIGS. First, when the apparatus is started, it waits for a film to be loaded (inserted in the case of a piece film) (step S11). (The steps are omitted below). S
When the film is loaded in 11, the winding motor is rotated in the forward direction, and in the case of the piece film 13, the feed roller 10
However, in the case of the film 12 stored in the cartridge, the film feed gear 11 in the cartridge is normally rotated. Then, the magnetic information recorded on the inserted film is read to check the presence or absence of the magnetic information (S15, S17). If magnetic information is incorporated in the inserted film, it is determined whether or not perforation is present (S19). When there is perforation, magnetic information is read (S
21). If it is determined in S17 that the film does not have a magnetic surface, it means that a film without magnetic information has been inserted or the film has been inserted by mistakenly facing the front and back, so a warning is issued (S33). If it is determined in S19 that there is no perforation, it means that the film has been inserted into the device by mistakenly inserting the film into the device. Therefore, a warning is also issued and the film is discharged (S33, S35).

Here, it is assumed that magnetic information indicating a photographing condition is recorded on the film reproduced by the film player, and the perforation for positioning the film is provided only on one of the upper side and the lower side of the film. ..

This film is carried out by the motor 9 shown in FIG.
By reversing. Next, by reading the photographing time information magnetically recorded on successive frames on the film, the order in which the photographs are photographed is determined (S23). Based on the determination result, it is determined whether the film is a normal wind film (a film that can be wound up one frame at a time) or a prewind film (a film in which one frame is wound up for all frames and a film is rewound for each frame). Thereby, the winding flag WF is set or reset (S25, S27). Next, the initial position of the film is determined (S29). Specifically, the top of the frame is placed on the imaging surface. Next, the audio is reproduced and an instruction to display the initial screen is given (S35, S37). In this initial screen display, for example, a demo screen may be displayed, or characters such as "Minolta" may be displayed.

Next, the video signal is started (S39),
The winding flag WF is determined, and it is determined whether the film is normally rotated or reversely fed by two frames according to the state of the film (S41, S43, S47). Here, the reason why such a determination is made will be described with reference to FIG. FIG. 11A shows the case where the film 20 is normal wind, and FIG. 11B shows the case where it is prewind. In either case, the frames are shot in the order of a, b, and c, and it is assumed that the image processing of the frame b has just finished. It is assumed that the magnetic information 24 is sequentially recorded in the direction of the arrow on each frame.

In the case of normal wind, since the frame c is scanned next, in order to move the frame c to the imaging area b, the film 20 is sent in the direction of the arrow shown in (A), and the magnetic head 4 reads the magnetic information 24. be able to. On the other hand, in the case of the prewind shown in (B), in order to read the next frame c, first move the frame c to the position of the frame a and then read the magnetic information 24 without reading the magnetic information 24. I can't.

In this way, the position of the frame is determined,
The film feed motor 9 is stopped (S49, S5
1). Next, it is determined whether electro-zoom (EZ) is requested (S53). This information is recorded in the magnetic information 24. When the electro-zoom is requested in S53, the lens is telephoto by the converter lens 23 and then the image is taken, and when the electro-zoom is not requested, the lens is imaged as it is (S55, S57).

When it is desired to perform the trimming image pickup in this way, the electrozoom enlarges the image by a factor of 2.
Since the image is taken by using the converter lens 23 shown in (1) as a telephoto lens, a 4 × image is taken together.

Next, the light source 5 is turned on, the photometry of the film surface is performed using the photometric sensor 21, the diaphragm 22 is controlled based on the photometry, and the scanning by the CCD 17 is performed.
After that, the light source 5 is turned off (S59 to S6).
9).

When the scanning is finished, the next frame is moved to the image pickup area (b in FIG. 11) in advance, and at the same time, the information of the next frame is read (S71, S73). Whether or not the converter lens 23 is necessary is previously determined from the EZ information of the next frame, and the image effect is performed in that state (S75, S7).
7). The details of this video effect will be described later.

Then, it is determined whether the next frame can be scanned (S79). This is determined in order to scan the next frame if there is no need to process the information in the imaging data memory 45 of the next image while the image of the previous frame is still output. Next, it is determined whether the frame being reproduced is the final frame (S81). This is determined by the information in the magnetic information 24, and if it is determined that it is the final frame, multi-screen display is performed in which all the frames imaged so far are displayed on one screen (S83).

If it is determined in S81 that the one being reproduced is not the final frame, the program returns to S59 and the routine up to this point is repeated.

An instruction is given as to whether the number of screens is 4, 9, or 25 (S85). This instruction is made using the operation switch 49, for example.

Next, in order to perform multi-screen display, all the frames photographed up to that point are returned one frame at a time in the reverse order of the reproduction, and each image information and magnetic information is stored in the CPU.
Entered in.

That is, the film 20 is returned frame by frame, the lens is set, the light source 5 is turned on, the photometric sensor 21 performs photometry, and the diaphragm 22 is controlled (S).
87-S95). Then, the CCD 17 performs a rough scan. When multi-screen display is performed, scanning is performed while skipping a part of the image in order to shorten the scanning time (S97). When scanning while skipping image information, for example, when four screens are displayed at once, the image information is reduced to 1/4, and when nine screens are displayed at one time, it is set to 1/9. Good.

Next, the light source is turned off and multi reproduction is performed (S99, S101). 4 screens with a predetermined number of screens, 9
It is determined whether the number of faces becomes 25 (S103),
When the number of screens reaches a predetermined number, it is determined whether or not the first frame is returned (S105), and the multi-playback operation is repeated until the first frame is returned (S105). If the number of screens does not reach the predetermined number in S103, the program returns to S87.

Although the multi-reproduction (S101) is performed before the number of screens is determined (S103), it may be performed after the number of screens is determined (S103). That is,
If the multi-playback is performed before the screen number determination, predetermined screens are sequentially output to predetermined positions, whereas if the multi-playback is performed after the screen number determination, the entire multi-screen is displayed at one time.

In the above embodiment, the final frame is determined and the multi-screen display is performed. However, even if the final frame is not the final frame, for example, only the frames of the same date are displayed on the multi-screen. Good.

By thus performing the multi-screen display at the end, the multi-playback can be performed while rewinding the film.

Next, when the first frame is returned to, the multi-screen is displayed for a certain period of time, then the reproduction of the video is ended and the audio is stopped (S107 to S111).

Next, the image effect described in S77 of FIG. 9 will be described. 12 to 14 are flowcharts showing the contents of the video effect.

First, it is determined whether or not the magnetic information 24 includes information such as the base color of the film 20, color development, gamma correction, density and color used in printing in the laboratory (S201). If it is determined that the information is included, the color tone or gamma correction is instructed according to the information (S203), and if not, the presence or absence of the light source type information is next determined (S205). Here, information such as whether the light source used for photographing is a fluorescent lamp, tungsten light, or a flash is used. Color balance is instructed according to the presence / absence of the information, and the top / bottom information of the film 20 is determined (S209). Even when there is no light source information in S205, the top-bottom information is determined next. If the film is judged to be upside down according to the top-bottom information, an image rotation instruction is given (S211), and it is judged whether or not it is a continuous photograph (S213). If it is determined in S213 that it is not a continuous photograph, time and date information is determined (S215). When it is determined that there is no information in S215, a random number is generated, and thereby the display method of the image on the screen is switched to either scroll switching or cutback switching (S217, S219, S22).
1). Here, the scroll switching display means, for example, a case where the video is sequentially switched from the left end of the screen, and the cutback switching means that the next video is instantaneously switched from the previous video.

When it is known in S213 and S215 that the photographs are continuous photographs and the time and date are known,
Overlap switching is performed so that the next image is reproduced while the image being reproduced disappears (S223).

In any of the switching operations, it is determined whether or not the image switching may be performed in order to set the timing with the image previously displayed (S225), and it is determined that the switching may be performed. If so, the frame is switched (S227). If it is determined in S225 that switching should not be performed (during zooming, etc.), the process waits until switching is permitted.

Next, it is determined whether or not there is user information, and if there is, user information is output and superimposed (S231, S233). Here, the user information is information input by the user at the time of shooting or after shooting, for example, the title of the frame.

Next, it is determined whether or not it is a continuous photograph regardless of the presence or absence of user information (S235). This is to prevent zooming in the case of continuous photographs in order to show the transition smoothly. If it is determined in S235 that the photograph is not a continuous photograph, a zoom start instruction is given to perform double zooming, and it is determined whether or not the photograph is a vertical photograph (S237, S239, S241).
If it is determined in step S241 that the photograph is not a portrait image, it is determined whether the photograph is a panoramic photograph (S243). If it is determined that the photograph is a panoramic photograph, a panning start instruction is issued (S247), and if not, an oblique movement start is instructed (S247).
245). If it is determined in S241 that the photograph is a vertical position photograph, a tilt start instruction is issued (S249).

Here, tilt start, panning start and the like will be described with reference to FIG. 15A is a diagram showing a case of diagonal movement, FIG. 15B is a diagram showing a panning state, and FIG. 15C is a diagram showing tilting.

Referring to FIG. 15A, when the photograph is neither a vertical position nor a panoramic photograph, the photographs are taken in order from diagonally above to diagonally below or vice versa as shown in the figure. In the case of a panoramic photograph, the photograph is panned in the horizontal direction as shown in FIG. (C) is a diagram showing a tilting state, and a photograph is taken in the vertical direction. In any case of (A) to (C),
The image processing circuit 48 does not pick up an image in only one direction, but when the image reaches one end in one direction, the direction is automatically changed and the other end is changed.

When the reproduction of the photograph is continued for a certain period of time as described above (S251), the oblique movement, panning and tilting from the center of the photograph where the image pickup is first started are completed, and the photograph is returned to the initial position again. It is determined whether or not it has been hit (S253). If it is determined in S253 that the lens has returned to the center position, the screen returns to the first screen and zooming ends (S255).

[0059]

As described above, according to the present invention, the first film accommodated in the cartridge and the piece-shaped second film not accommodated in the cartridge are similarly moved to the predetermined image pickup area by the film conveying means. The image on the film is conveyed and converted into a video signal.

As a result, both the film and the piece film stored in the dedicated cartridge are reproduced by one film player.
