Abstract

PURPOSE:To recognize circumstances of photographing at the time of reproducing by measuring circumstances of photographing by a measuring means incorporating a camera at the time of photographing to record information indicating the measured result on a video tape. CONSTITUTION:A temperature sensor 30 and a humidity sensor 32 are arranged, and a button 34 or the like to selectively display the weather is provided, and outputs of sensors 30 and 32 and the button 34 are applied to a controller 36. The controller 36 controls a character generator 38 to inprint numerical values or symbols indicating the temperature and the humidity onto a picture based on detection outputs of the temperature sensor 30 and the humidity sensor 32 and controls the character generator 38 to inprint the symbol mark indicating the weather for photographing onto the picture in accordance with the operation of the button 34. Thus, information indicating the circumstances like the temperature of photographing is inprinted on the picture, and the atmospheric condition or the like for photographing is recognized at the time of reproducing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a video camera, and particularly to a video camera capable of recording various information.

[Conventional technology]

Some conventional video cameras of this type are capable of directly imprinting the date, time, or stopwatch display on the video. This allows the date and other information at the time of shooting to be displayed during playback, which has the advantage of immediately reviving the fun of the movie, and is an essential feature, especially for recording children's growth.

Some also have a title function that allows text or illustrations to be imprinted on the video as appropriate.

[Problem to be solved by the invention]

By the way, as mentioned above, being able to know the date of shooting and adding a title to the video is one way to enjoy the recorded video.
Conventionally, there has been no video camera capable of recording information other than the above, ie, information indicating the shooting environment such as the temperature and weather at the time of shooting.

Furthermore, if you can record information indicating the shooting environment mentioned above, you will be able to enjoy the video recorded from a different perspective than the date, etc., and if the video records the experiment, you will be able to check the experimental data along with the video. This is significant in that it allows for

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a video camera that can imprint information indicating the shooting environment on a video.

[Means to solve problems]

In order to achieve the above object, the present invention is characterized by comprising a measuring means for measuring a photographing environment, and a means for recording information indicating the measurement results of the measuring means on a videotape during recording.

[Effect]

According to the present invention, at the time of photographing, the photographing environment is measured by a measuring means built into the camera, and information indicating the measurement results is recorded on a videotape. As a result, information indicating the shooting environment is imprinted on the video, and the shooting environment can be 1RXIIk during playback.

〔Example〕

Preferred embodiments of the video camera according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of a video camera according to the present invention.

In the figure, the light incident through the photographic lens 10 is
An image is formed on the light receiving surface of the CCD solid-state image sensor 12, and each sensor converts the light into an amount of signal charge corresponding to the intensity of the light. This one
The No. 1 charges are sequentially read out and output to the signal processing circuit 14.

The signal processing circuit 14 includes a white balance circuit, a T correction circuit, a masking circuit, an encoder circuit, etc. After performing predetermined signal processing using these circuits, N T
Outputs one word of SC format video.

The video signal is applied to an electronic viewfinder (EVF) 18 and a recording signal processing circuit 20 via a summing point 16. EVF l 8 includes a small CRT display,
Displays the video being shot based on the manually input video signal.

Further, the recording signal processing circuit 20 converts the input video signal into a recording signal suitable for magnetic recording, and this recording signal is recorded on a video tape 26 via a recording amplifier and a rotary head 24.

On the other hand, this video camera is provided with a temperature sensor 30, a humidity sensor 32, and a button 34 for selectively displaying the weather.
The outputs of button 2 and button 34 are applied to controller 36.

The controller 36 controls the character generator 38 to imprint various information on the image, and imprints numerical values and symbols indicating temperature and humidity on the image based on the detection outputs of the temperature sensor 30 and the humidity sensor 32. Further, a character generator 38 is installed so that a symbol mark indicating the weather at the time of photographing is imprinted on the video in accordance with the operation of the button 34.

The character generator 38 generates data for displaying predetermined numbers, symbols, symbol marks, etc. on the screen, and reads the data as appropriate based on the control signal from the controller 36 and outputs it to the addition point 16.

At the addition point 16, the video signal applied from the signal processing circuit 14 and the signal indicating the photographing environment such as temperature added from the character generator 38 are added, and the EVF 18
and is output to the recording processing circuit 20.

As a result, information indicating the shooting environment such as temperature is displayed on the screen displayed on the EVF 18, and this video signal is transmitted to the video tape via the recording processing circuit 20, the recording amplifier, and the rotating head 24. It is recorded on 26.

FIG. 2 is a diagram showing an example of a screen on which information indicating the above-mentioned photographing environment is displayed. As shown in the figure, a symbol mark indicating sunny weather, temperature of 21° C., humidity of 30%, etc. are displayed.

In addition, in FIG. 2, the date, time, stopwatch, etc. are also displayed. These dates and the like can be recorded by providing the controller 36 with a timer function. Further, among the various types of information described above, only necessary information may be selectively recorded by button operations.

[Effects of the Invention] As explained above, according to the video camera according to the present invention, information indicating the shooting environment such as temperature can be imprinted on the video. This has the advantage that the weather conditions at the time of shooting can be recognized, the video can be enjoyed even more, and when an experiment is photographed, experimental data can be recorded along with the video.
