Abstract

PURPOSE:To stably record successively by recording an image signal for each one picture successively at prescribed intervals, and preventing the change of a recording mode meanwhile. CONSTITUTION:First, by a switch group 121, whether a mode setting entrance such as a successive photographing mode field/frame, etc., exists or not is inspected, next, whether the input of a SW 1 is executed or not is discriminated, a motor 109 is started when it is executed, and a video floppy 108 is rotated. Thereafter, a head 107 is moved to a next track position, and at such a time, when a SW 2 is pushed, whether the switch is turned on or not is discriminated, and when it is not turned on, a transfer is re-executed. Here, in the middle of the successive photographing, a control part does not accept the inputs of all mode switches except for the switch to decide whether the successive photographing is continued or not among the switch group 121. Consequently, in the middle of the successive photographing, the change of the recording mode is executed, the speed of a successive recording is stabilized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording device for recording image signals in storage means.

[Prior Art] An example of a conventional device for recording an image signal in a storage means is a recording device called a still video recording device, which performs recording by forming concentric tracks on a magnetic disk.

[Problems to be Solved by the Invention] The above-mentioned device has a function called a continuous recording function, that is, a function of recording image signals on a disk at a rate of, for example, two or five screens per second. There is a device that

In such recording devices, it is important to maintain the aforementioned speed constant and to be able to perform continuous recording at high speed, thereby stabilizing and improving the recording characteristics of the device.

Further, in the above-mentioned apparatus, there are cases where the recording modes are various. For example, there is a mode called field recording mode in which one screen worth of image signals is recorded on one concentric track on a magnetic disk, and a mode called frame recording mode in which one screen worth of image signals is recorded on two concentric circles on a magnetic disk. There is.

Here, there is a problem in that if the recording mode is switched while the above-mentioned continuous recording is being performed, it is difficult to keep the continuous recording speed sufficiently stable.

In view of this point, it is an object of the present invention to provide a recording device that can stably perform continuous recording.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides a recording device that has a plurality of recording modes when recording image signals on a recording means, and that continuously records image signals for each screen at predetermined intervals. and a control means for preventing the recording mode from being changed during continuous recording by the means.

[Operation] The control means does not change the recording mode during continuous recording by the continuous recording means.

[Embodiments] In the embodiments of the present invention described below, an electronic still camera that records on a magnetic disk is shown, but the present invention is not limited to such a device, but is applicable to recording that records on an optical disk or tape-shaped medium fixed memory. Of course, it may be a device or a device without an imaging section.

According to the embodiment of the present invention described below, an electronic still camera is provided with a means for detecting whether or not it is in quick shooting mode or in self-mode operation. With the exception of the switch that determines whether or not to continue continuous recording, all mode switches, including the switch that sets the recording mode, do not accept input, so that continuous recording can be performed stably. A device is disclosed. In addition, in this embodiment, when the self mode is operating, all the switches except for the switch that determines whether to continue the self mode and the switch that allows you to set the mode with a -degree operation. The mode switch does not require manual input.

In other words, in a device that allows one switch to have multiple functions to reduce the number of switches, the operation becomes somewhat complicated, so for example, it is difficult to operate the switch during self-mode operation. However, according to this embodiment, which will be explained below, this inconvenience is solved by doing the above-mentioned method. You can.

Embodiments of the present invention will be described in detail below with reference to the drawings.

is a group of switches.

In the switch group 121, SWI and SW2 are the first release switch. A second switch, FI/FR, is a switch for switching between field recording mode and frame recording mode, and SET is a switch for switching various modes, and 5ELECT, UP, and DOWN are used to set the mode.

In the above configuration, the operation in continuous shooting mode will be explained according to the flowchart of FIG.

First, if it is checked from the switch group 121 whether there is a mode setting entrance for continuous shooting mode field/frame, etc., the state is set accordingly (S200, 5200-1).

Here, during continuous shooting (i.e., when repeating steps 5205 to 5209), the control unit selects the switch group 121 at 5209, 5209-1) to determine whether or not to continue quick shooting. is SW2. C0NT, 5ING
Except for LE and 5ELF, all mode switch inputs are not connected. Therefore, the recording mode is not changed during continuous shooting, and the speed of continuous recording is stabilized.

Next, the operation in self mode will be explained according to the flowchart of FIG. In the figure, the same parts as in Figure 2-a are designated by the same numbers.

This flow is executed when the self-timer mode is set in advance by the 5ELF switch.

First, it is checked from the switch group 121 whether there is a mode setting such as field/frame (S200), and if there is, the status is set (S200-1).

Next, in the switch group 121, it is checked whether there is manual power for SW2 (S210-1). If there is an input, the self-mode is started (3210), and at this time, the self-timer is reset. That is, the AF circuit 112, the AE circuit 113,

), the flow branches to 5202. While the self-timer is measuring time, all mode switches except those detected at 5240 and 5250 do not receive input.

As explained above, according to this embodiment, in an electronic still camera, when a snapshot is being taken, all mode switches are not operated manually except for the switch that determines whether or not to continue the snapshot. By doing so, it is possible to reduce the time required for key scanning to check whether there is a switch input during rapid shooting, and furthermore, there is no need for manual switch processing, so the CPU can exclusively control continuous shooting. This makes it possible to take high-speed snapshots.

Also, if self mode is operating, all mode switches will not be operated manually except for the switch that determines whether to continue self mode and the switch that allows you to set the mode with a single operation. By doing so, it is possible to avoid the inconvenience of recording an unnecessary image on a video floppy due to a timeout while operating a switch during self-mode operation.

Furthermore, in the above-described embodiment, two recording modes, field recording mode and frame recording mode, are shown as recording modes of the recording apparatus, but the present invention is not limited to these, and other recording modes, such as skip recording, are also possible. Similarly, in a device that is capable of switching to a recording mode, that is, a mode in which the head 107 is moved by one track so that an empty track is created every time an image signal is recorded on one track, this recording mode is similarly disabled during continuous recording. It may also be possible not to accept mode changes.

In such a case, as shown in FIG. 4, 5200 shown in FIG.
Instead, a step is provided to determine whether or not a skip mode setting switch is turned on, and if the skip mode is set in step 5208, the head is moved so that one empty track is formed. You can do it like this.

[Effects of the Invention] As explained above, according to the present invention, it is a block diagram showing the configuration of an example of continuous recording.
