BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film image input device, and more particularly, to a film image input device for capturing an image recorded on a photographic film and outputting an image signal indicating the image to a monitor TV.

[0002]

2. Description of the Related Art A photographic film is picked up by an image pickup means, an image of the photographic film is converted into an image signal, and this is converted to a monitor TV.
2. Description of the Related Art A film image input device for outputting a film image to a camera and displaying the film image is known. The film image input device is provided with an illumination unit for projecting light toward a photographic film, a photographic lens unit, and a solid-state image sensor such as a CCD on the same axis. The film is disposed between the illumination unit and the lens unit on the optical axis, and the light emitted from the illumination unit is projected onto an image recorded on the film. Light transmitted through the film is collected by the taking lens unit and
An image is formed on D, and the image recorded on the film is converted into an image signal and output. As a result, a film image can be reproduced on the monitor TV connected to the film image input device. Some of the film image input devices include a zoom mechanism for changing a photographing magnification, a film scanning mechanism (XY moving mechanism), and an image sensor rotating mechanism (USP. 4,482,924, USP. 4,
485,406, USP. 4,506,300 etc.).

[0003]

By the way, in this type of film image input device, zooming of a photographing lens and scanning of a film are performed to extract only an image in a necessary range from one frame of the film.
The image can be displayed (trimmed) on the entire screen of the monitor TV, but is displayed on the monitor TV because the aspect ratio when the film is printed is different from the aspect ratio of the screen of the monitor TV. When viewing a film image, the user cannot view the same image as the actually printed photo. For example, when the trimming conditions for printing are set while watching the monitor TV, the trimming conditions are recorded on a magnetic recording layer or the like provided on the film, and the recorded trimming conditions are read in a lab and automatically printed. There is a problem that a photograph different from the photograph considered at the time of setting the trimming condition is printed.

The present invention has been made in view of such circumstances, and a film image which can be displayed so that the aspect ratio of a film image displayed on a monitor TV and the aspect ratio of a photograph are the same. An object is to provide an input device.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an image pickup means for picking up an image of a negative film or a positive film and outputting an image signal indicating the picked-up image. Frame generating means for generating a frame signal indicating the frame of the ratio, and a frame being synthesized with the film image based on the image signal output from the imaging means and the frame signal generated from the frame generating means, and the frame is synthesized. Image synthesizing means for outputting an image signal indicating a film image.

[0006]

According to the present invention, an image signal obtained by taking an image of a negative film or a positive film and a frame signal indicating a frame having the same aspect ratio as the photograph generated by the frame generating means are combined by the image synthesizing means. The signals are combined, and the combined signal is output to the monitor TV. This allows the monitor image to be viewed in the same image as the actual print.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a film image input device according to the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing one embodiment of a film image input device according to the present invention. As shown in FIG. 1, this film image input device captures an image of a developed film 10 by an image capturing device including a photographing lens (zoom lens) 12 and an image sensor (CCD) 14, and an image signal indicating the captured image. Is output to the image synthesizing circuit 16 in the image processing unit. The details of the image synthesis circuit 16 will be described later.

A frame feed switch 3 for commanding frame feed of the film 10 is provided on the operation unit 30, for example, as shown in FIG.
1A and 31B, zoom switches 32A and 32B for instructing zoom-in and zoom-out of a film image, and scan switches 33A and 3 for instructing scanning of a picture in one frame.
3B, 33C, 33D, rotation command switches 34A, 34B, 34C for commanding the rotation of the CCD 14, a standard switch 35, and a frame switch 36 for outputting a command for synthesizing a frame with a film image are provided.

Here, the standard switch 35 is a switch for returning the scanning position to the center of the film and returning the photographing magnification to the standard magnification and outputting a command for reproduction. The standard magnification includes a horizontal standard magnification corresponding to the case where the picture projected on the frame of the film 10 is landscape and a vertical standard magnification corresponding to the case where the picture projected on the frame is portrait. There are two types of lateral standard magnifications. That is, the first magnification that can be considered as the horizontal standard magnification is a magnification at which the left and right edges of the frame of the film 10 coincide with the left and right edges of the monitor screen. In this case, since the aspect ratio of the film (aspect ratio 2: 3) and the monitor screen (aspect ratio 3: 4) are different, portions other than the picture of one frame appear on the upper and lower ends of the monitor screen. The second magnification considered as the horizontal standard magnification is a magnification in which the upper and lower edges of the frame of the film 10 coincide with the upper and lower edges of the monitor screen. In this case, both side portions of the film image are shaded and are not monitored. On the other hand, the vertical standard magnification is a magnification at which the upper and lower edges of the picture coincide with the upper and lower edges of the monitor screen when the picture projected vertically in the frame is turned upright by rotating the CCD 16 by 90 °. is there.

A signal output by operating various switches on the operation unit 30 is applied to the control circuit 22 and a frame synthesizing command by operating the frame switch 36 is also applied to the frame generating circuit 18. ing. The control circuit 22 includes a zoom switch 32 of the operation unit 30.
When a zoom signal is input by operating A and 32B, the zoom mechanism 24 is controlled according to the zoom signal, thereby performing zooming of the zoom lens 12, and zooming in and out of the film image. The focus mechanism 25 focuses the zoom lens 12.

When a scan signal is input by operating the scan switches 33A, 33B, 33C and 33D of the operation unit 30, the control circuit 42 controls the scan mechanism 26 in accordance with the scan signal, thereby controlling the up and down movement of the film image. Scanning in the left-right direction is performed. The scanning of the film image in the left-right direction (X direction) is performed by winding or rewinding the film 10, and the scanning in the up-down direction (Y direction) is performed by moving the zoom lens 12 up and down.

Further, when the control circuit 42 inputs a frame feed signal by operating the frame feed switches 31A and 31B of the operation section 30, the scanning mechanism 2 receives the frame feed signal.
6, the film 10 is fed in the X direction by a pitch amount of one frame, and the rotation command switches 34A, 34B, 34
When a rotation command is input by operating C, the CCD rotation mechanism 28 is controlled in accordance with the rotation command, and the CCD 14 is controlled by ± 9.
Can be rotated 0 °. This makes it possible to cope with the case where the film image is vertically projected on the film 10.

When the frame switch 36 is in the OFF state, no frame signal is generated from the frame generating circuit 18 and the image synthesizing circuit 16 outputs the image signal input from the CCD 14 to the monitor TV 20 as it is. Thereby, the monitor T
As shown in FIG. 3A, an image having an aspect ratio of 3: 4 is displayed on the screen of V20. On the other hand, when the frame switch 36 of the operation unit 30 is turned on and a frame synthesis command is input, the frame generation circuit 18 outputs a frame signal to the image synthesis circuit 16. An image signal indicating a film image is added to the image synthesizing circuit 16 from the CCD 14, and the image synthesizing circuit 16 synthesizes these signals, and outputs an image signal indicating the frame-synthesized film image to the monitor TV 20. . This allows
On the screen of the monitor TV 20, an image in which the film image is incorporated in the frame 19 is displayed as shown in FIG.

Here, the frame 19 is preset so that the aspect ratio of the film image in the frame matches the aspect ratio (2: 3) of the photograph of the service size. That is, the frame generation circuit 18 outputs a frame signal indicating a frame having the same aspect ratio as the photograph to the image composition circuit 16. 3 (A) and FIG.
As is clear from the comparison with (B), the image with the frame is smaller than the image without the frame, so that the image in the same range can be seen. That is, the frame switch 36
Is turned on, the control circuit 22 automatically controls the zoom mechanism 24 so that the photographing magnification becomes α times (α <1), and the image with the frame becomes α times the image without the frame. To shrink. Note that α is determined in advance by the width of the frame 19.

The type of the frame 19 is not limited to a rectangular frame, but may be a frame shown by oblique lines in FIGS. 4A to 4D. In short, the aspect ratio of the film image is made to match the aspect ratio of the photograph. Any frame may be used as long as it is in such a frame. In the above embodiment, the horizontal frame of a horizontal photo has been described. However, in the case of a vertical photo, the frame generation circuit 18 generates a vertical frame signal as shown in FIG. The horizontal or vertical photo is C
It can be automatically determined from the rotational position of the CD 14. Further, the frame generation circuit 18 generates a frame signal for setting the aspect ratio to 1: 3 when the photograph has a panoramic size (FIG. 5B), and sets the aspect ratio to 9 when the photograph is a half size. : 16 can be generated (FIG. 5C).

Next, the operation of the film image input device will be described with reference to the flowchart of FIG. First,
It is determined whether or not to display a frame based on whether the frame switch 36 is ON or OFF (step 100). When displaying a frame, the frame type (service size, panorama size, half size) is determined by key input from a frame type selection switch (not shown) of the operation unit 30 (step 102). Subsequently, the vertical and horizontal directions of the photograph are determined from the rotational position of the CCD, and a vertical frame or a horizontal frame is selected (step 10).
4).

Next, it is determined whether or not a frame is currently being displayed (step 106). If no frame is being displayed, the screen is muted (step 108). During this muting, the zoom mechanism is controlled so that the image before displaying the frame enters the frame (step 110), and then the mute is released (step 112). Then, after the zoom mechanism and the scanning mechanism are manually controlled as necessary (step 114), the selected frame and the currently photographed image are combined and displayed on the monitor TV (step 106).

In steps 108 to 112, the image is muted once before the frame is displayed, and then the screen is displayed after controlling the zoom mechanism so that the image before the frame is displayed in the frame. However, the present invention is not limited to this.For example, when displaying a new frame, mute once before displaying the frame, then cancel the current zoom position and the scan position, and set a zoom mechanism and a zoom mechanism so that the entire photo falls within the frame. The screen may be displayed after controlling the scanning mechanism, or the frame may be overwritten on the current image without muting. Further, the zoom-out may be performed so that the image before the frame is displayed, and at the same time, the frame may gradually appear from around, or the zoom-out may be performed after the frame is displayed.

On the other hand, if it is determined in step 106 that the frame is currently being displayed, the process proceeds to step 114, where the zoom mechanism and the scanning mechanism are manually controlled as necessary while the frame is being displayed. Can be trimmed. Note that the zoom and scan ranges are restricted so that parts other than photos are not displayed on the screen. However, the limited range differs between when displaying a frame and when not displaying a frame. However, the limited range differs depending on whether the frame is a vertical frame or a horizontal frame, and also depending on the type of the frame.

If it is determined in step 100 that the frame switch 36 is in the OFF state, that is, the frame is not displayed, the process proceeds to step 118, where it is determined whether the frame is currently being displayed. When the frame is displayed, the processing in steps 120 to 124 is the reverse of the processing in steps 108 to 112. That is, the frame is muted once before the frame is erased, and then the zoom mechanism is controlled so that the image in the frame fills the entire screen, and then the screen is displayed.

Thereafter, if necessary, the zoom mechanism and the scanning mechanism are manually controlled (step 12).
6) Only the image currently being photographed is displayed on the monitor TV (step 128). On the other hand, if it is determined in step 118 that the frame is not currently being displayed, the process proceeds to step 126, and the desired trimming is performed by manually controlling the zoom mechanism and the scanning mechanism as necessary without displaying the frame as in the related art. Is available.

When frame advance is performed while the frame is displayed, the current zoom position and scan position are released, the zoom mechanism and the scan mechanism are controlled so that the entire photograph is within the frame, and then the next frame is scanned. Or release the current zoom position, scan position and frame display, and control the zoom mechanism and scan mechanism so that the entire picture fills the screen of the monitor TV, and then display the image of the next frame. Can be considered.

The screen is muted during frame advance until the next frame image is displayed. The frame color is set so that the frame color matches the muting background color at this time.

[0024]

As described above, according to the film image input device according to the present invention, the image is displayed such that the aspect ratio of the film image displayed on the monitor TV is the same as the aspect ratio of the photograph. The monitor image can be viewed in the same image as the actual print. Further, since the film image is bordered by the frame, there is an effect that the film image is enhanced.
