Abstract

PURPOSE:To reflect feeling of a photographer onto a picked up picture by providing a sensor measuring the feeling to a grip. CONSTITUTION:A sensor 24 outputs a signal corresponding to the degree of feeling of a photographer such as tension-relax based on a temperature or humidity of a hand or an electric resistance of the skin surface. Moreover, in general, when a human being hightens the tension, he is in a sweat, resulting that the humidity of the hand is increased, the resistance of the skin surface is decreased and the temperature of the hand is decreased due to contraction of capillary vessels. A color tone decision section 18 decides a color tone of the picture so that the color is red when the tension is high and the color is blue when the degree of relax is high based on a signal from the sensor 24 and outputs a signal representing the decided color tone to a signal processing section 14, in which the color balance of R, G, B signals is changed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a video camera, and more particularly to a video camera capable of expressing the emotions of a photographer.

[Conventional technology]

Conventionally, in order to express the photographer's emotions using a camera, it is necessary to make full use of framing, filter work, etc.

[Problem to be solved by the invention]

However, there is a problem in that experience and intuition are required to reflect emotions in a photographed image as described above, and it is troublesome even for an expert to carry out this type of photographing.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a video camera that can automatically reflect the emotions of a photographer in a photographed image.

[Means to solve problems]

In order to achieve the above object, the present invention disposes at least one of a temperature sensor, a humidity sensor, and a resistance sensor on a grip portion that holds a video camera, and based on the output of the disposed sensor, The camera is characterized in that the emotions of the photographer are reflected in the photographed image.

[Effect]

The present invention focuses on the fact that emotions in response to various psychological stimuli can be measured from the perspective of psychoelectric reflexes by utilizing sweating caused by excitement, tension, etc., and a decrease in hand temperature caused by constriction of capillaries, etc., and uses a video camera. A sensor for measuring the above-mentioned emotion is provided in the grip portion of the device. Based on the output of this sensor, the photographer's emotions are reflected in the captured image.

〔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 an external view showing an embodiment of a video camera according to the present invention. In the figure, 10 is a video camera body, and 20 is a grip attached to the bottom of the video camera 10.

A recording button 22 for instructing start/stop of recording is disposed on the grip 20, and a sensor 24 is disposed at a portion that is always in contact with the hand. This sensor 24 detects one or more of the temperature, humidity, or electrical resistance of the skin surface of the hand.

FIG. 2 is a block diagram of essential parts of the video camera shown in FIG. 1. In the same figure, light indicating a subject is photoelectrically converted by an imaging unit 12, and photoelectrically converted red (R), green (G), and blue (B) signals are sent from the imaging unit 12 to a signal processing unit 14.
is output to.

The signal processing unit 14 includes a sample hold circuit, a white balance circuit, an rM positive path encoder, etc.
The R, G, and B signals inputted from 2 are appropriately processed to generate a color video signal, and this is output to the recording/reproducing section 16. The recording/reproducing unit 16 converts the color video signal inputted from the signal processing unit 14 into a signal suitable for magnetic recording and magnetically records it on a video tape, and also reads the recorded signal from the video tape during playback and demodulates it into a color video signal. do.

Now, the sensor 24 outputs a signal corresponding to the photographer's emotion, ie, the degree of tension to relaxation, based on the temperature and humidity of the hand or the electrical resistance of the skin surface. Generally, when humans are nervous, they sweat, which increases the humidity of their hands, lowers the resistance value of the skin surface, and lowers the temperature of their hands due to the contraction of capillaries.

Based on the signal from the sensor 24, the color tone determination unit 18 determines the color tone of the image so that it becomes reddish when the degree of tension is high, and bluish when the degree of relaxation is high, and indicates the determined color tone. The signal is output to the signal processing section 14 to change the color balance of the R, G, B signals in the signal processing section 14.

FIG. 3 is a block diagram of main parts showing another embodiment of the video camera according to the present invention. Note that parts common to those in FIG. 2 are given the same reference numerals, and detailed explanation thereof will be omitted.

In FIG. 3, a photographic lens 12A and an image sensor 12B
A filter 25 is disposed on the front surface of the photographing section 12, which is comprised of the following. This filter 25 is a color filter that continuously changes between red and blue as shown in FIG.

The controller 26 drives the motor 28 via the driver 27 based on the signal input from the color tone determining section 18, and controls the rotational position of the filter 250 so as to achieve the desired color balance with respect to the signal input from the color tone determining section 18.

In the above embodiment, the color balance of the color image is changed according to the photographer's emotions, but the invention is not limited to this, and the brightness level or chroma level may be changed.

FIG. 4 is a block diagram showing a main part of still another embodiment of the video camera according to the present invention, and shows the case where the emotional level is displayed as a bar. Note that parts common to those in FIG. 2 are given the same reference numerals, and detailed explanation thereof will be omitted.

In FIG. 4, the power determining unit 3o determines the power according to the degree of tension of the photographer, so that the power increases as the degree of tension of the photographer increases, based on the signal from the sensor 24,
A signal indicating the determined frequency is output to the controller 32.

The controller 32 reads character information for displaying the degree as a bar from the character generator 34 based on the signal applied from the degree determining section 3o, and superimposes a bar display 36 indicating the emotional degree on the screen as shown in FIG. pose.

Note that the display of the emotional level is not limited to the bar display of this embodiment, and various display methods such as displaying with numbers can be considered.

Furthermore, the mounting position of the sensor 24 is not limited to the undergrip attached to the bottom of the video camera body 10, but may also be a side grip provided on the side of the video camera body.

〔Effect of the invention〕

As explained above, according to the video camera according to the present invention, the emotions of the photographer can be automatically reflected in the captured image, and even people without special training can express their emotions using the video camera. becomes.
