Abstract

PURPOSE:To record a video image as intended by a photographer itself by bringing a camera main body into the movie mode when no pickup is taken and sending a picked-up video signal as a TV radio wave and displaying the video image onto a TV receiver built in other remote controller provided separately. CONSTITUTION:A TV receiver 12 with a liquid crystal display device built therein and a remote control transmitter 13 are integrated. When no pickup is taken, a system control circuit 7 controls an optical section 1 and an image pickup signal processing circuit 3, which is in the movie mode. The switch 6 is turned off and an object image is not recorded onto a magnetic disk 9 by a recording head 8. On the other hand, a TV radio wave sent by an RF conversion circuit 10 is visualized by the TV receiver 12 in the remote controller and the content of pickup is grasped by an electronic still camera. Thus, the state picked up actually is confirmed by a photographer itself and the video image as intended is formed while being optimized.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a remote-controlled electronic still camera that records captured video signals on a storage medium such as a magnetic disk.

2. Description of the Related Art Conventional remote-controlled electronic still cameras, although not particularly shown in the drawings, are digital still cameras equipped with a receiving section, and a shutter operated by a signal from a separate remote control device to take pictures. be.

Problems to be Solved by the Invention However, with the above configuration, for example, when a user wants to take a photograph of himself or herself, the user cannot look through the finder, so the composition and focus cannot be optimized. In particular, since it is not possible to check the actual shooting conditions, the intended image cannot be recorded, which results in a loss of value.

In view of the above, the present invention provides a remote-controlled electronic still camera that can confirm the actual shooting conditions and record the intended image while optimizing the composition and focus in any case. The purpose is to provide cameras.

! Means for Solving IE1 The present invention is capable of switching between movie operation and still camera operation, and includes an imaging means in the main body and at least a video signal captured by the imaging means during movie operation.
a first transmitting means for transmitting radio waves; a recording means for recording a video signal captured by the imaging means during operation of the still camera; a receiving means for receiving a remote control signal from a separate remote control device; T.
This is a remote-controlled electronic still camera with a built-in V receiver.

Operation The present invention has the above-described configuration, and when not shooting, puts the camera body into the movie mode, transmits the captured image signal as TV radio waves, and projects the image on a TV receiver built in a separate remote control device. In any case, the photographer can check the actual shooting conditions and control the operation of the main unit by signals from this remote control device, making it possible to produce images exactly as the photographer intended. , it is possible to record while optimizing the composition and focus.

Embodiment FIG. 1 shows the main body of a remote control electronic still camera according to an embodiment of the present invention, and FIG. 2 shows a separate remote control device.

In Fig. 1, 1 is an optical section consisting of a lens, a focusing mechanism, an aperture, a zooming mechanism, etc.;
is a CCD that captures a subject image that enters through the optical section 1.
Element 3 is an imaging signal processing circuit that drives this CCD element 2 and processes its signals. 4 is an imaging signal processing circuit 3
5 is a recording amplification circuit. 6 is a switch whose on/off is controlled by a system control circuit 7. 8 is a recording head, and 9 is a magnetic disk. Reference numeral 10 denotes an RF unit that performs RF conversion processing on the video signal obtained from the imaging signal processing circuit 3 and transmits it as a TV radio wave.
It is a conversion circuit, and 11 is a light receiving part for a remote control signal.

This signal is sent to the system control circuit 7.

In FIG. 2, 12 is a TV receiver incorporating a liquid crystal display, and 13 is a remote control transmitter, which are integrally constructed.

The operation of the remote control electronic still camera configured as described above will be described below.

While not photographing, the system control circuit 7 controls the optical section 1 and the imaging signal processing circuit 3 to enter the movie operating state, the switch 6 is off, and the subject image is recorded on the magnetic disk 9 by the recording head 8. It never happens.

On the other hand, the TV radio waves transmitted by the RF conversion circuit 10 are visualized by the TV receiver 12 in the remote control device.
You can understand the content captured by an electronic still camera. Therefore, the photographer can check the actual shooting conditions and create the video as intended while optimizing the composition and focus.

When a photograph is to be taken, a command is issued using the remote control, and the transmitter 13 of the remote control transmits the contents of the command using infrared rays. This is received by the remote control signal light receiving section 11 in the main body, and the system control circuit 7 controls the optical section 1 and the imaging signal processing circuit 3 to enter the still camera operating state, and at the timing specified by the system control circuit 7. The switch 6 is turned on, and the intended subject image is recorded on the magnetic disk 8 by the recording head 8 as a video signal.

When recording is completed, the system control circuit 7 turns off the switch 6 again, returning to the initial state.

As described above, according to the ninth embodiment, it is possible to switch between movie operation and still camera operation by the system control circuit 7, and during the movie operation, the optical section 1,
The video signal captured by the CCD 2 and the imaging signal processing circuit 3 is subjected to RF conversion processing by the RF conversion circuit IO, and is transmitted as TV radio waves, so that the image of the subject can be confirmed using the TV receiver 12 built into a separate remote control device. A remote control signal light receiving section 11 is provided inside the main body to receive command contents from a transmitter 13 of the remote control, and when shooting, the system control circuit 7 puts the camera into operation mode by operating the remote control, and the recording head 8 outputs the magnetic disk. By configuring the camera so that the subject image is recorded in 9, it is possible to always grasp the content of the image taken by the electronic still camera, and it is possible to record the intended image while optimizing the composition and focus.

In this embodiment, the TV receiver 12 has a built-in liquid crystal display, but it may also be configured with a display such as a cathode ray tube. In addition, although infrared rays were used as the remote control signal, other signals such as ultrasonic waves may also be used.
Of course, you can also connect it with a cable. Furthermore, it goes without saying that the recording head 8 and the magnetic disk 9 may be constructed of an optical disk, an IC memory, or the like.

As described in detail, according to the present invention, the photographer can confirm the actual state of the photograph in any case.
Since it is possible to control the operation of the main unit using signals from this remote control device, it is possible to record images as intended by the photographer, while optimizing the composition and focus, making it possible to put it into practical use. The effect is significant.
