Description

Field of application

The invention relates to a method and apparatus for recording and reproducing sound on and from a photographic image on paper or other material, which will find application in everyday life and in photography with conventional and digital cameras.

BACKGROUND OF THE INVENTION

There is a known method for recording and reproducing sound, in which, during the capture of a given image, the sound relating to the respective image is input from a microphone through an amplifier block of a recording device into an analog-to-digital converter. The signal is converted to a digital signal and stored in removable and removable audio memory. When shooting a camera, the recorder always records a specific digital code to identify the information corresponding to each camera. Sound reproduction is achieved by passing the stored audio information into a digital-to-analog converter, after which the transmitted signal is transmitted through the amplifier block of the sound reproducing device to the loudspeaker.

A sound recording and reproducing apparatus consisting of a recording and sound reproducing device is also known. The sound recorder consists of a microphone connected in series through an amplifier block of the recorder and an analog-to-digital converter to a movable and replaceable block of sound memory. A control unit of the recording device is connected to the analog-to-digital converter and to the mobile and removable unit of the recording memory. The audio device is composed of a digital-to-analog converter connected through an amplifier block of the audio device to the speaker. The digital-to-analog converter and the amplifier unit of the audio player are connected to its control unit. All elements of the sound recording and reproducing device are connected to a power supply unit.

With the known method and apparatus, it is not possible to record and reproduce sound on and from a photographic image on paper or other material. It is also not possible for the method and device to be applied to all types of cameras.

SUMMARY OF THE INVENTION

It is an object of the invention to provide a method whereby sound can be recorded and reproduced on and off a photographic image on paper or other material.

It is an object of the invention to provide a device for carrying out the method.

This task is solved by a method whereby, during a photographic image taken with a digital or conventional camera, a microphone records the sound propagating at the time the subject is captured. The sound received through the microphone is amplified by an amplifier of a recording device (PSU) and then passed through an analog-to-digital converter, where the analog signal is converted to digital and recorded in audio memory. This memory is removable and removable as it has a certain capacity that is exhaustive and requires replacement.

When capturing a still image, the RAM encodes the received signal so that there is a correspondence between a particular still image and the associated sound recorded during the capture of the photographic image.

The information from the removable and removable memory is transferred by means of a copier onto the sound memory of the photographic image on paper or other material medium, so that the sound memory medium becomes an integral part of the photographic image.

When viewing photos, the sound is played back3

65493 Bl produces from a sound reproducing device (IUU) in which the photographic memory of the photographic image is inserted. It is a digital signal that passes through a digital-to-analog converter. The signal is converted from digital to analog, then passed through an amplifier block and played back by a loudspeaker.

The device for carrying out this method is combined and consists of a sound recording device (PA) and a sound reproducing device (SOA) that can operate both independently and independently of one another.

The memory is made up of a microphone that receives the sound recorded during the shooting of the camera and is connected to an amplifier block. This block, which is used to amplify the received signal, is connected to an analog-to-digital converter, which converts the analog signal to digital and sends it to removable and removable recording memory. The analog-to-digital converter and the audio memory are connected to the RAM control unit.

The removable and removable memory is transferred by a copier to the photographic image audio memory carrier, which is an integral part of the photographic image itself.

The LAS is composed of a digital-to-analog converter, which converts the digital signal into an analog signal and sends it to an amplifier block, where the signal is amplified to the appropriate level and sent to the speaker connected to the amplifier block. The sound is output from the speaker. The ZVU control unit is connected to the photographic image audio memory carrier and to a digital-to-analog converter.

All elements of the sound recorder and playback device are connected to a power unit and are self-powered.

According to one variant, applicable to snapshot cameras, the analog-to-digital converter of the memory is connected directly to the sound memory of the photographic image. When a photo is taken, the sound is recorded directly on the photographic image memory.

Advantages of the invention are the ability to perform synchronized recording and reproduction of sound on and from paper or other material media of a photographic image, as well as its applicability to all types of cameras.
