Description

Digital photography camera

The present invention relates to a digital photographing camera, and more particularly, to a digital photographing camera that photographs a scene for a predetermined time and digitally stores the selected scene, and selects a desired scene from the stored images and outputs the selected scene as a photograph.

As known, various technologies such as a camera, a projector, and a camcoder have been developed to photograph a desired scene for a long time.

The conventional camera is a method of photographing a still cut by adjusting the exposure time at various speeds by a shutter method, and a projector is a method of photographing a scene to be photographed on a film with at least about 20 continuous cuts per second, The camcorder stores images on a magnetic tape approximately 30 frames per second.

The scene photographed by the above-described conventional photographing method is divided into about 30 shots per second even if the camcorder is used, and it is impossible to further store the divided images per second.

Of course, a speed of about 1/8000 seconds is possible with the camera, but the speed is limited to only one cut. It is impossible to take high-speed continuous shooting (specifically 400 shots per second at 1/400 second intervals).

Therefore, there has been a problem that it is difficult to accurately capture a desired scene in a conventional photographing apparatus in a field of measurement requiring a high-speed robot or high-speed special photographing.

Even if an image photographed using a conventional camcorder is outputted as a photograph, there is a problem that an image is deteriorated by a processor such as signal compensation, which is indispensable to an analog signal processing system, and it is difficult to obtain a high-quality image as a photograph.

Therefore, conventionally, there has been a problem that it is difficult to develop a photograph satisfying exactly a desired image and a high-quality image at the same time by using photographing devices such as a camera or a camcorder due to factors such as a problem on the apparatus, .

An object of the present invention is to provide a digital photographing camera for photographing a scene for a predetermined time and storing it in a digital manner, and outputting a high-definition image of a desired extremely minute instant with a photograph.

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

In addition, a digital / analog signal output unit for converting the digital signal output from the central control unit into the analog signal may be further provided.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, an image sensor (also referred to as a "photographing device") 10 is connected to an encoder and a compression unit 12 for inputting a digital signal obtained by photographing a specific scene, (12) is connected to digitally code and compress the input photographing signal to apply it to the memory (14).

The central control unit 18 connected to the operation switch 16 having a plurality of keys for function setting and execution is connected to control the image sensor 10, the encoder and the compression unit 12 and the memory 14 have. The memory 14 reads the image data output from the encoder and the compression unit 12 to a designated area and stores the image data stored in the designated area by the control for reading / And reads and outputs the data.

The central control unit 18 converts the image data read out from the memory 14 into a digital / analog (D / A) converter 20, a digital output unit 22 and a photograph unit 24, M, and the digital / analog converter 20 converts the input digital video signal into an analog video signal and outputs the analog video signal to an externally connectable analog recording device (not shown) or a display device (not shown) And the digital output unit 22 is configured to decode the input digital video signal and output it to an externally connectable digital recording device (not shown) or a display device (not shown).

The operation and effect of the embodiment according to the present invention constructed as described above will be described.

The operation switch 16 is basically provided with switches for setting various functions for photographing, and may be further provided with various switches according to a function to be set as an auxiliary for photographing.

When a switch for photographing is operated among a plurality of switches formed on the operation switch 16, the image sensor 10 is driven under the control of the central processing unit 18 to sense a desired scene, and a digital signal The central control unit 14 outputs a signal processing control signal to the encoder and the compression unit 12 during the predetermined period of time and outputs the signal processing control signal to the encoder and the compression unit 12 12 and controls the coding and compression of the digital image signal processed by the controller 12 and applies the control signal for the storage to the memory 14 to store the digital image data input from the encoder and the compression unit 12 in the designated address sequentially .

A scene for a predetermined time to be sensed by the image sensor 10 is converted into a digital image signal and stored in the memory 14 via the encoder and the compression unit 12. [ Here, the video signal is transmitted, coded, compressed and stored in a digital manner.

The photographing is performed for a predetermined time as the photographer operates the operation switch 16 by the above-described method, and the photographing time can be determined according to the capacity of the memory 14 and the operation of the operation switch 16 of the photographer.

Then, the central control unit 18 can control signal processing in the encoder, the compression unit 18, and the memory 14 so as to change the degree of image storage per second.

That is, the image data from the encoder and the compression unit 12 is divided into output signals in the order of 1/8 second, 1/16 second, 1/32 second, 1/64 second, The storage of the image data may be controlled so as to store the split screen, and the encoder and the compression unit 12 may transmit the image data by the basic seconds division (for example, 1/64 second) 14) can be controlled so that the storage of the image data can be controlled at a different second division speed (for example, 1/8 second or 1/16 second).

Also, the central control unit 18 can also control the output of the video data so as to output a desired scene by reading out the screen stored in the memory 14 in seconds. That is, the image data stored in the memory 14 is basically changed into 1/8 second, 1/16 second, 1/32 second, 1/64 second, and the like by the digital / analog converter 20, the digital output section 22, and the photograph section 24, respectively.

As described above, the photographic unit 24 outputs image data stored in a digital state and output in a digital state as a photograph, and there is no damage to image data due to signal deterioration during the intermediate signal processing process. And a scene photographed at a desired speed can be obtained as a photograph according to the storage control and the output control of the digital image data.

By using high-speed microprocessor control technology and high-capacity memory, it is possible to easily store and output images over a photograph speed equal to 1/8000 second.

As described above, according to the present invention, the restriction of the reduction in the photographing time, which is stored at a time interval of about 1/30 per second by the image recording by the conventional analog image processing method, is solved, There is an advantage to be able to.

Since digital signal processing does not require a process such as signal degradation compensation, a digital photographing camera according to the present invention can obtain a high-quality photograph.

Therefore, according to the present invention, it is possible to easily acquire a photograph of a desired exact point-in-time and to reproduce a scene at a precise point in time with a high-quality photograph.

And it can be widely used in automation field and measurement field as well as in general photographing because it is applied to special high-speed measurement and photographing device, or to capture the movement of a robot driven at high speed.
