89). If no information is input (# 87: N
O), the data read in # 55 is written as it is to the magnetic tape 41 of the frame, or writing is not performed.

Next, it is judged whether or not the frame of the reproduced image is the final frame of the film 4 (# 91). Since the F1 frame is not the final frame (NO in # 91), both the variable F and the variable J are incremented. (# 93). Next, if the tip of the F2 frame has not reached the imaging area A (N in # 95
2), the drive motor 810a is normally rotated (# 97), and
As shown in 0, when the front end of the F2 frame reaches image pickup area A (YES in # 95), drive motor 810a is stopped (# 99).

Thereafter, the process returns to # 63 and the drive motor 810
When a is rotated in the normal direction, the film 4 is fed in the arrow direction (feeding direction) of FIG. 21, and the image pickup of the F2 frame image is started (# 65). At the same time, the magnetic head 821 reads the data of the magnetic tape J3 corresponding to the F3 frame, and the magnetic head 822 writes the data such as the reproducing method for the F1 frame to the magnetic tape J1 (# 69, # 71). . After this, as in the previous time, # 73- #
Processing of 99 is performed. However, in # 81, the process waits until the data writing to the magnetic tape J1 is completed.

On the other hand, if the frame currently being imaged is the final frame in # 67, there is no frame to be reproduced next, and therefore # 6.
The processing of 9 and # 79 is skipped, and the data writing to the magnetic tape 41 corresponding to the frame immediately before the last frame is performed. And in the case of the last frame (YE in # 91
S), the drive motor 810a is normally rotated (# 101), data is written to the magnetic tape 41 corresponding to the final frame (# 103), and when this data writing is completed (YES in # 105), the drive motor 810a is stopped (# 107), and the processing of this flowchart ends.

Thus, the magnetic head is composed of the read-only magnetic head 821 and the write-only magnetic head 822, and the image pickup start position of one frame is the image pickup area A of the image pickup section 86.
The magnetic head 821 is located at the reading start position of the magnetic tape 41 corresponding to the next frame, and the magnetic head 822 is located at the recording start position of the magnetic tape 41 for the previous frame. Therefore, it is possible to simultaneously capture a film image by the image capturing unit 86 and read and write data on the magnetic tape 41 corresponding to the front and rear frames thereof. Therefore, the processing time required for data reading, imaging, and data writing can be shortened. In this embodiment, data reading and data writing were performed on the magnetic tape 41 corresponding to the front and rear frames of the frame being imaged.
It is also possible to dispose two or more frames upstream of the frame in which the image is picked up, and to arrange two or more frames downstream of the frame in which the magnetic head 822 is imaged, in the downstream direction.
In this case, the data read by the magnetic head 821 is stored until the frame corresponding to the read magnetic tape 41 is imaged.

Next, a third embodiment of the film image reproducing apparatus 1 will be described with reference to FIG. The same reference numerals as those in FIG. 15 have the same functions. In the third embodiment, an image pickup section 860 including an area image sensor is used instead of the image pickup section 86. Further, as the light source 83, one having a shape capable of enlarging the illumination range and giving an appropriate amount of light to the entire image pickup frame is adopted.

The image variable power unit 850 comprises a taking lens 851, a prism 852, and a diaphragm (not shown). Shooting lens 8
Reference numeral 51 serves to form an image of the film 4 on the image pickup section 860 and to perform zooming according to an operation of the data input section 7 such as a zooming knob (not shown). The prism 852 is for rotating the image on the film 4 so that the image is taken in an upright state with the camera oriented vertically. The imaging unit 860 is a CCD (solid-state imaging device)
Etc. arranged in a matrix form, 1 of film 4
The whole image of the frame is picked up.

Further, as shown in FIG. 26, the magnetic head 821 has the film 4 in the image pickup area B of the image pickup section 860.
The magnetic head 822 is arranged at the leading end position of the frame on the upstream side in the feeding direction, and the magnetic head 822 is arranged at the rear end position of the frame on the downstream side in the feeding direction of the film 4 with respect to the imaging area B.

Next, the operation of the film image reproducing apparatus 1 according to the third embodiment will be described with reference to the flowchart of FIG. 23 and FIG.
This will be described with reference to the operation explanatory diagrams of FIGS. The first piece will be described as F1 and the second piece as F2.

When the film cartridge KT is loaded in the cartridge loading portion 5, the variable F indicating the frame number of the film 4 and the variable J indicating the number of the magnetic tape 41 are both set to "1"(# 111).

Then, the drive motor 810a is normally rotated,
The magnetic head 821 starts reading the data stored in the magnetic tape J1 corresponding to the F1 frame (# 1
13, # 115), when the data reading from the magnetic tape J1 is completed (YES in # 117), it is determined whether or not the F1 frame has reached the image pickup area B based on the detection result of the film position detection unit 13. (# 119). Then, as shown in FIG. 24, when the F1 frame reaches the image capturing area B (YES in # 119), the drive motor 810a is stopped, the image of the F1 frame is captured by the image capturing section 860, and the image of the F1 frame is the magnetic field. It is processed based on the data read from the tape J1 and reproduced on the screen 3 of the monitor TV 2 (# 121 to # 127).

Subsequently, it is determined whether or not the information on the reproduction method of the F1 frame has been input (# 129). If the information has been input (YES at # 129), the reproduction method is selected according to the information. It is changed (# 131).

Next, it is judged from the value of the variable F whether or not the frame of the reproduced image is the last frame of the film 4 (# 13).
3), F1 piece is not the last piece (N in # 133
O), the drive motor 810a is rotated in the normal direction, and the film 4 is fed in the arrow direction (feeding direction) of FIG. next,
Data writing on the F1 frame to the magnetic tape J1 is started, and at the same time, data reading on the magnetic tape J2 corresponding to the F2 frame is started (# 135 to # 139).
If no information is input (NO in # 129),
The data read in # 115 is written as it is to the magnetic tape J1 or is not written.

Next, when the data writing to the magnetic tape J1 is completed (YES in # 141), it is determined whether the data reading of the magnetic tape J2 corresponding to the F2 frame is completed (# 143). The magnetic tape J2
When the data reading of is completed (YES in # 143),
It is determined whether or not the F2 frame has reached the imaging area B (# 1
45), as shown in FIG. 26, when the F2 frame is fed to the imaging area B (YES in # 145), the drive motor 810
a is stopped, the variables F and J are both incremented (# 147, # 149), and the process returns to # 123 to reproduce the F2 frame.

On the other hand, when the image reproduction processing up to the final frame is completed (YES in # 133), the drive motor 810a is rotated in the normal direction, and data is written to the magnetic tape 41 corresponding to the final frame (# 151, # 151). # 153). continue,
It is determined whether or not the data writing to the magnetic tape 41 corresponding to the last frame is completed (# 155), and when the data writing to the magnetic tape 41 corresponding to the last frame is completed (YES in # 155), this flowchart The process ends.

In this way, the data can be written on the magnetic tape 41 corresponding to the frame of the reproduced image by the magnetic head 822 at the same time when the data is read from the magnetic tape 41 corresponding to the next frame by the magnetic head 821. The time required for reading and writing data can be shortened. In this embodiment, the magnetic head 821 reads the data on the magnetic tape 41 corresponding to the next frame and the magnetic head 822 writes the data on the magnetic tape 41 corresponding to the frame of the reproduced image. As in the second embodiment, the gap between the magnetic head 822 and the magnetic head 821 may be two or more frames.

In the third embodiment, the magnetic head 821
May be arranged, for example, so as to be located below the tip of the imaging region B, and the magnetic head 821 and the magnetic head 822 may have a space for one frame. In this case, since the magnetic head 821 is interposed between the light source 83 and the film 4, it is necessary to arrange the magnetic head 821 so as not to block the light from the light source 83.

In each of the above embodiments, the magnetic tape 41 is used as a data recording medium. However, the recording medium is not limited to this. For example, data is written on the edge of the film 4 by an optical means to write the data. As you do
The imprinted data may be optically read. Further, in each of the above embodiments, the magnetic tape 41 as a recording medium is arranged on the film 4, but the recording medium (magnetic tape 41) may be configured separately from the film 4.

[0074]

According to the present invention, the reading of data from the recording medium by the data reading means and the writing of data to the recording medium corresponding to the reproduced frame by the data recording means can be performed at the same time. The processing time for reading and writing data can be shortened.
