Description

The present invention drives a shutter to copy a subject image and an electromagnetic wave / particle beam pattern onto a film, or converts the image or the pattern into an electrical signal by a CCD (Charge Coupled Device) or the like. In particular, the present invention relates to a camera that can reduce camera shake during shooting.

The so-called silver salt camera, which captures the subject image and electromagnetic wave / particle beam pattern on the film, has been widely used for portrait photography and X-ray photography. A so-called digital camera (also referred to as an electronic still camera) for electronic recording has come to be often used due to features such as image processing and ease of distribution.

In the silver halide camera, the release button mechanically drives the shutter, and when the release button is pushed, the shutter is driven to record an image or the like on the film. On the other hand, in a digital camera, the release button drives an electric shutter to
An operation for storing a subject image captured in D in a memory provided in the digital camera is performed. By pressing a release button, the subject image or the like is stored in the memory as image data. Hereinafter, such an operation of recording a subject image or the like by driving a mechanical or electrical shutter is simply referred to as a release.

Conventional silver halide cameras and digital cameras both operate by directing the lens toward the subject and pressing the release button. Since this release button is composed of a mechanical switch, for example, FIG. As shown, when the release button 50 is pressed down, the entire camera 51 may rotate to the right, causing a so-called camera shake. When camera shake occurs, there is a problem that the image is out of focus and the image quality of the photograph is impaired.
In particular, in a silver salt camera with a large film size or a digital camera with a large number of pixels, even a very slight camera shake has a large effect on image quality.

In recent years, since the weight of cameras has been decreasing, recent cameras are in the direction of lack of stability in return for improved portability, and it is also true that camera shake tends to occur. In addition, when using a zoom lens with a small size and a high magnification, it is unavoidable to use a dark lens having a large open F value, and the influence of camera shake is further increased.

In order to prevent this camera shake, it is conceivable to lighten the release button or use a touch sensor as the release button.

Also, when the cameraman turns on / off the zoom function or the image stabilization function or switches the image stabilization control mode according to the purpose of shooting, the TV camera should not be subjected to excessive vibration.
There is an operation command instruction system for a TV camera that can turn on / off a zoom function or an image stabilization function or switch an image stabilization control mode by voice (for example, Patent Document 1).
reference).

Also, when the shutter button can be operated independently in two different directions, the focus lock and exposure can be performed with one shutter button, and when the command voice of a predetermined level or higher is recognized after the focus is locked In addition, there is an autofocus camera that performs exposure (see, for example, Patent Document 2).

A camera system comprising a camera and a camera accessory for attracting children's attention attached to the camera, wherein the start signal for operating the camera accessory is in the form of electric signal, sound wave, radio wave, light, etc. There is a camera system provided with a remote controller for supplying to (see, for example, Patent Document 3).
JP 2003-110922 A JP 11-194392 A Japanese Patent Laid-Open No. 9-244136

However, if the release button is lightened or a touch sensor is used as the release button, the release button is easily pushed, so that the release is performed when the photographer does not intend to shoot. was there.

In addition, the conventional technique described in Patent Document 1 uses a headset instead of operating a mechanical switch such as a push button to perform a tele / wide operation of a zoom function or an ON / OFF of a vibration isolation function in a TV camera. It can be performed by inputting sound into a microphone provided for the above, and does not operate a shutter of a silver salt camera or a digital camera.

Further, the prior art described in Patent Document 2 makes the operation of the shutter button at the time of exposure lighter than the operation of the shutter button at the time of performing exposure with a camera having a focus lock mechanism by pressing the shutter button halfway. Although it is possible to operate the shutter in two directions, it is difficult to understand the procedure unless you are fully used to it.
There was a problem that the operation method was unknown and confused. In addition, when sound of a certain level or higher is input to a sound collecting microphone provided in front of the camera, exposure is performed to reduce camera shake. In some cases, the voice of the photographer instructing the exposure is extinguished by noise and cannot be determined and does not operate, or malfunction may occur depending on noise.

In addition, the prior art described in Patent Document 3 is a camera accessory that is operated by a remote controller or voice so that children's attention is directed to the camera accessory so that camera shake can be concentrated on shooting. The camera shutter is not operated by remote control or voice. Patent Document 3 describes that the camera self-timer is remotely controlled. In this case, a remote controller for remote control is required.

The present invention has been made to solve the above-described problems, and provides a camera capable of reliably releasing a camera when a photographer intends to shoot and reducing camera shake during shooting. With the goal.

According to this configuration, when the shooting mode is the normal mode, the control unit compares the second voice signal from the second A / D converter with the keyword voice signal registered in the keyword registration unit, and the same. A release signal is given to the release means when it is recognized. On the other hand, when the shooting mode is the self-timer mode, the control unit compares the first audio signal from the first A / D converter with the keyword audio signal registered in the keyword registration unit and finds that they are the same. A release signal is given to the release means a predetermined time after the recognition. Then, the release means to which the release signal is given gives the subject image formed through the photographing lens at that time to the recording means for recording.

According to a fourth aspect of the present invention, in the second or third aspect of the present invention, the subject image is formed and photoelectric conversion means for converting an optical signal into an electric signal is provided, and the release means is given a release signal.

The means records the image data in the image memory.

In the invention of claim 5, in the invention of claim 4, the photoelectric conversion means is a CCD, the release means is a release circuit for converting an electrical signal from the CCD into image data, and the keyword registration means is a keyword. It is a registration memory, wherein the photographing mode switching means is a photographing mode switching key, and the control means is a CPU.

According to this configuration, when the shooting mode switched by the shooting mode switching key is the normal mode, the CPU uses the second voice signal from the second A / D converter and the keyword voice registered in the keyword registration memory. The release signal is given to the release circuit when the signals are compared and recognized as the same. On the other hand, if the shooting mode is self-timer mode,

The release circuit to which the release signal is given is
Image data of the subject image formed on the CCD at that time is generated from the electrical signal from the CCD and applied to the CPU, and the CPU records the image data in the image memory.

As described above, according to the present invention, since the subject image can be recorded by the keyword voice, when the photographing mode is the normal mode, the photographer presses the release button when holding the camera toward the subject. Instead, the subject image can be recorded by uttering the keyword voice. That is, since the camera can be released without pressing the release button, the occurrence of camera shake during shooting can be reduced.

In this normal mode, the microphone that receives the keyword voice from the photographer is
Since the microphone is provided on the back of the camera body facing the photographer, even if there is a noise source on the subject side, it is difficult for noise from the noise source to be input to the microphone on the back. The voice uttered by the photographer is easily input. Therefore, the voice produced by the photographer is not drowned out by the noise from the noise source, and the keyword voice produced by the photographer can be reliably discriminated, so that the release can be ensured when the keyword is produced. Can be done. Further, the noise does not cause a malfunction that the release is erroneously performed.

When the shooting mode is the self-timer mode, instead of pressing the release button, the photographer who is the subject speaks by speaking the keyword voice toward the front of the camera body facing the photographer. The release can be performed after a predetermined time from the time. In other words, the camera can start the self-timer countdown from a remote location without pressing the release button and without using a remote controller, etc., improving convenience without increasing the cost of the camera Can be made.

In addition, in the self-timer mode, the microphone to which the keyword voice generated by the photographer is input is a microphone provided in front of the camera body facing the subject.
It is easy for a voice uttered by a photographer located on the subject side to be input. Accordingly, it is easy to determine the keyword issued by the photographer, and it is possible to easily start the countdown of the self-timer when the keyword is issued.

The image forming apparatus further includes a photoelectric conversion unit that forms a subject image and converts an optical signal into an electrical signal, and the release unit converts the image data of the subject image from the electrical signal from the photoelectric conversion unit when a release signal is given. Since the generated image data is recorded in an image memory as a recording means, the subject image can be recorded as digitized image data.

The photoelectric conversion means is a CCD, the release means is a release circuit for converting an electrical signal from the CCD into image data, the keyword registration means is a keyword registration memory, and the shooting mode switching means is a shooting mode switching key. Since the recording means is an image memory and the control means is a CPU, it is possible to realize a digital camera that reduces camera shake by releasing with sound and records a subject image as digitized image data.

Further, the digital camera 1 shown in FIG. 1 includes a release button 9 at the upper end portion.

FIG. 2 is a block diagram showing the configuration of the digital camera shown in FIG. For convenience of explanation, the same parts as those in FIG. In FIG. 2, 10 is a CPU and CP.
When the power of the digital camera 1 is turned on, the U 10 reads this firmware from a firmware ROM 14 such as a flash memory in which firmware that is a control program of the CPU 10 is written, and the digital camera 1 based on the read firmware.
Take overall control.

Further, the CPU 10 has a key operation signal of the release button 9 and the operation key 8, a front sound signal obtained by digitally converting the sound input from the front microphone 3 by the A / D converter 12,
In addition, the back audio signal obtained by digitally converting the audio input from the back microphone 6 by the A / D converter 13 is input.

In addition, the digital camera 1 is provided with a CCD 11 for converting reflected light from a subject incident through an imaging optical system including an imaging lens 2a inside the lens barrel 2 shown in FIG. A release circuit 1 that generates image data of a subject image formed on the CCD 11 from an electrical signal from the CCD 11 and supplies the generated image data to the CPU 10.
7 is provided. That is, the release circuit 17 has an electrical shutter function.

When the release is performed, the CPU 10 gives the release signal to the release circuit 17 and stores the image data sent from the release circuit 17 in the image memory 16. C
The PU 10 reads out the image data stored in the image memory 16 and displays it on the liquid crystal display 5 in accordance with the operation of the operation key 8 or the like.

The image data stored in the image memory 16 is subjected to predetermined signal processing such as compression by the CPU 10. The image memory 16 is a compact flash (registered trademark) or SD.
A removable external memory such as a card may be used. In that case, the external memory is mounted, and a memory reader / writer for reading / writing to the external memory is required.

The digital camera 1 has a nonvolatile keyword registration memory 15 composed of an EEPROM or a flash memory, and the CPU 10 registers in the keyword registration memory 15 a keyword voice signal obtained by digitally converting a keyword voice used for voice release. (save.

Next, the operation at the time of shooting of the digital camera 1 having such a configuration will be described with reference to FIGS. 3 and 4 are flowcharts for explaining the operation of the digital camera 1.

When the power source of the digital camera 1 is turned on, first, the CPU 10 executes the firmware ROM 1
After the firmware necessary for control is read from 4 (step S1), it is confirmed whether or not a keyword voice signal for starting release by voice is registered in the keyword registration memory 15 (step S2).

If the keyword audio signal is not registered, the keyword registration process is started.
The PU 10 waits for voice input from the rear microphone 6 (step S3). Next, CPU
Reference numeral 10 denotes a back face audio signal obtained by digitally converting the voice of the photographer input from the back microphone 6, for example, a keyword sound such as “yes, cheese” or “start” by the A / D converter 13. And temporarily stores the input back surface audio signal (step S).
4). The CPU 10 determines that the keyword input has ended when the sound from the back microphone 6 is interrupted (step S5), and registers the temporarily stored back sound signal as the keyword sound signal in the keyword registration memory 15. (Step S6).

In this way, keyword registration is performed. At this time, the rear audio signal obtained by digitally converting the audio input while the setting / decision key of the operation key 8 is pressed is registered as the keyword audio signal. good. Further, the keyword voice may be input from the front microphone 4 instead of the rear microphone 6.

Then, after the keyword voice signal is registered in the keyword registration memory 15 or when it is confirmed in step S2 that the keyword voice signal has already been registered in the keyword registration memory 15, the shooting mode, shooting conditions, etc. are set. (Step S7), and if there is such a request, setting change processing such as the shooting mode and shooting conditions is performed (step S8). The shooting mode, shooting conditions, and the like are set by the photographer operating each key of the operation keys 8 while referring to the setting display on the liquid crystal display 5.
The PU 10 can confirm whether there is a setting change request from the key operation signal of the operation key 8.

This shooting mode includes a still mode for shooting a still image, a moving image mode for shooting a movie, a normal mode in which the photographer holds the digital camera 1 facing the subject, and the photographer himself becomes the subject. For this reason, there is a self-timer mode in which the release is performed after a predetermined time, and either the still mode or the moving image mode, and either the normal mode or the self-timer mode are always selected. .

When the release is performed in the moving image mode, the image data from the release circuit 17 is stored in the image memory 16 for a preset recording time. At the same time, an audio signal obtained by digitally converting audio input to the front microphone 3 by the A / D converter 12 is also stored in the image memory 1.
6 is stored. Note that the image data or audio signal stored in the image memory 16 includes CP
Predetermined signal processing such as compression is performed by U10.

The shooting conditions include various conditions that can be set with a general camera, such as white balance, exposure, aperture, strobe setting, etc. Omitted.

Next, it is confirmed whether or not the shooting mode is the self-timer mode (step S9).
In the self-timer mode, first, it is confirmed whether or not the release button 9 has been pressed (step S10). If not, it is determined whether or not a keyword has been input to the front microphone 3. When a keyword is input, the self-timer counts down (step S11). When the count reaches 0, a release is performed (step S12). After the release is performed, step S7 is performed. Return to.
At this time, the CPU 10 determines that a keyword has been input by recognizing that the front audio signal from the A / D converter 12 is the same as the keyword audio signal registered in the keyword registration memory 15. Is called.

On the other hand, when there is no keyword input (step S13), it returns to step S7 as it is. If the release button 9 is pressed (step S10), the self-timer counts down (step S11), and release is performed when the count reaches zero (step S11).
Step S12).

On the other hand, when the self-timer mode is not set, that is, in the normal mode (step S9), first, it is confirmed whether or not the release button 9 is pressed (step S14).
If not, it is determined whether or not a keyword has been input to the rear microphone 6 (
Step S15) If a keyword is input, release is performed (Step S12).
After the release, the process returns to step S7. On the other hand, if there is no keyword input (step S15), the process directly returns to step S7. Further, when the release button 9 is pressed (step S14), the release is performed (step S12), and after the release is performed, the process returns to step S7. At this time, the CPU 1 determines that a keyword has been input.
0 is performed by recognizing that the back audio signal from the A / D converter 13 is the same as the keyword audio signal registered in the keyword registration memory 15.

As described above, according to the present embodiment, release by voice can be performed. Accordingly, when the photographer is not in the self-timer mode, instead of pressing the release button 9 when holding the digital camera 1 toward the subject, the photographer can select “Yes, cheese” or “
By uttering a keyword registered in the keyword registration memory 15 such as “Start”, the digital camera 1 can be released. That is, the release button 9
Since the digital camera 1 can be released without pressing, the occurrence of camera shake can be reduced.

In the case of not being in the self-timer mode, the microphone to which the keyword issued by the photographer is input is the rear microphone 6 provided on the back surface of the digital camera 1 facing the photographer. Even if there is a source, noise from the noise source is less likely to be input to the rear microphone 6, and voice generated by the photographer is likely to be input. Therefore, the voice that the photographer utters is not drowned out by the noise from the noise source,
Since the keyword issued by the photographer can be reliably determined, the release can be surely performed when the keyword is issued. Further, the noise does not cause a malfunction that the release is erroneously performed.

In the self-timer mode, instead of pressing the release button 9, the photographer who is the subject faces the front of the digital camera 1 facing the photographer, “yes, cheese” or “start”. By uttering the keyword registered in the keyword registration memory 15 as described above, the digital camera 1 can start to count down the self-timer and release when the count reaches zero. That is, since the digital camera 1 can start the countdown of the self-timer from a remote position without pressing the release button 9 and without using a remote controller or the like, the cost of the digital camera 1 is increased. The convenience can be improved.

In the self-timer mode, the microphone to which the keyword issued by the photographer is input is the front microphone 3 provided on the front surface of the digital camera 1 facing the subject.
Therefore, it is easy to input the voice uttered by the photographer located on the subject side. Accordingly, it is easy to determine the keyword issued by the photographer, and it is possible to easily start the countdown of the self-timer when the keyword is issued.

The digital camera 1 of the present embodiment is provided with a release button 9 so that it can be handled in the same manner as a conventional camera release operation. However, as described above, the digital camera 1 has a voice release function. Since the release button 9 is provided, the release button 9 is not always necessary and can be an option. If the structure does not include the release button 9, the cost can be reduced accordingly.

Also, even when releasing with voice, no complicated operation is required, so when you ask someone else to shoot, instead of pressing the release button when shooting, `` Yes, cheese Just by asking them to say a keyword such as “Start” or “Start”, others who do not know the operation can easily shoot with reduced camera shake.

The camera of the present embodiment is a digital camera that digitizes a subject image and records it in a memory as image data. However, the present invention can also be applied to a silver salt camera. In this case, the CCD 11 of the digital camera 1 of this embodiment corresponds to a mechanical shutter, the release circuit 17 corresponds to a shutter drive circuit that drives the mechanical shutter, and the image memory 16 corresponds to a silver salt film. Further, the present invention is not limited to the above-described embodiment, and the configuration of each part can be appropriately changed and implemented without departing from the spirit of the present invention.
