Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an image forming apparatus such as a still video player that reproduces image information recorded on a magnetic recording medium by an electronic still camera or the like.

(Prior Art) In recent years, electronic still cameras, which record still images by miniaturizing magnetic disk recording devices and combining them with imaging means, have been in the spotlight. Image information recorded on a magnetic recording medium by this electronic still camera is played back by a still video player.

A conventional still video player has a built-in video floppy disk containing a magnetic recording medium.

(Problems to be Solved by the Invention) However, in the still video player configured as described above, while the magnetic head is moved to reproduce one screen image to the next,
There was a problem that the displayed screen was disordered and difficult to see.

Here, in order to avoid displaying a distorted screen,
Make the screen black while the magnetic head moves, or store one screen as it is in the frame memory,
The image signal from the memory may be displayed until the next screen is played.

However, if the screen is black while the magnetic head is moving, depending on the length of the head movement period,
The screen becomes discontinuous with the next screen, making the screen difficult to view. Furthermore, those that use frame memory are more expensive.

The present invention has been made in view of these problems, and its purpose is to provide an image reproducing device that has a simple configuration, has no image breaks or disturbances, can quickly switch between screens, and can reproduce continuous screens that are easy to view. The aim is to realize this.

(Means for Solving the Problems) The present invention, which solves the above-mentioned problems, includes a first drive that handles a first disk on which a screening program is recorded, and a first drive that is capable of writing and reading a plurality of tracks. a second drive that handles two disks, a control unit that inputs video signals from each of the first and second drives, and a display unit that displays the video signal output from the control unit, The heads of the first drive and the second drive are movable heads, and the control section includes a means for reading a screening program and reading the screening program recorded therein from the first disk at intervals of a predetermined number of screens. a dubbing means for dubbing video signals from the first and second drives to the second disk in sequence before the playback of the screening program starts; The screening programs read out alternately from the first and second disks are sequentially reproduced without image breaks and in the same order as the first disk, and one of the first and second drives is played back. The video signal is switched so that the image read by the movable head of the other drive is displayed until the movable head of the other drive finishes tracking.

(Function) In the image reproducing apparatus of the present invention, the screening program recorded on the first disk is previously dubbed onto the second disk at intervals of a certain number of screens, and dubbing is not performed during image reproduction. Therefore, there are no breaks or disturbances in the image when playing back the image.
Additionally, the time required to switch from one image to the next is greatly reduced.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to screens.

FIG. 1 is a configuration diagram showing an embodiment of the present invention, and FIG. 2 is a perspective view showing the external appearance of the device. In these figures, 1 represents the first video floppy.
, 2 is a second drive of the video floppy, and 3 is a control unit to which video signals from the first and second drives 1 and 2 are input. This control section 3 includes a screening program reading means 31,
Dubbing means 32 between the first and second drives 1 and 2, and video output switching and compositing means 33 from the first and second drives 1 and 2 are provided. 4
is a display means for displaying the video output output from the control section 3. For example, this display means
An NTSC television monitor is used.

The operation of the apparatus configured as described above will be explained as follows.

FIG. 3 does not explain the operation of the above embodiment.
First, screen A, B, recorded on the first video floppy set in the first drive.
Every other screen B, D, F among C, D, E...
The image signals of... are successively dubbed onto the second video floppy set in the second drive 2. After dubbing is completed, the first drive 1 and the second
screen A, screen B, screen C alternately from drive 2 of
...and playback. While one drive is tracking, the other drive is reproducing, and the display means 4 has no image breaks or disturbances, and easy-to-see screens A, B, C, etc. are successively reproduced.

FIG. 4 is an explanatory diagram showing the movement of the heads on the first and second video floppy disks when dubbing is performed every other fixed number of screens (every other screen in the case of FIG. 3) as in the above operation example. It is. Note that since a double gear head is used here, dubbing is performed every second. First drive 1
The image signals of every second screen C, D, G, H, etc. of the screens A, B, C, D, E, etc. recorded on the first video floppy set to Dubbing is performed one after another onto the second video floppy set to 2. After dubbing is complete, first start from the head of the first drive to screen A,
Image signals of screens C and D are sequentially output from the head of the second drive. The head of the first drive moves to the position shown by the dashed line while the image signal is being output from the second drive, and the head of the second drive moves to the position shown by the dashed line while the image signal is being output from the first drive. While there, move to the position indicated by the dashed line. Screen A,
By quickly switching the display of B, C, D, etc., a moving image-like display can be performed.

(Effects of the Invention) As explained above, in the present invention, before the playback of the screening program starts, the screening program recorded here is sequentially transferred from the first disk to the second disk at intervals of a certain number of screens. Dubbing is performed in advance, and dubbing is not performed while the image is being played.
When the screens are sequentially reproduced from the first screen, no breaks or disturbances occur in the images, and in addition, the time required to switch from one screen to the next is greatly reduced. Therefore, when the operator desires a high-speed search, in order to avoid dubbing one by one, it is functionally possible to make the playback time of each screen very short and play the screens one after another. It becomes possible to perform high-speed searches to find a desired screen by switching screens one after another without any breaks or disturbances.
