Description

Digital Film Apparatus {Digital Film Apparatus}

The present invention uses a conventional film as it is to add a digital camera function to an existing camera while inserting a film-like micro-digital camera module into an empty space into which a film enters instead of a film used as needed. The present invention relates to a digital film device that adds the function of a digital camera to an existing mechanical camera. In the reality that image processing technologies of almost all fields are being replaced by digitalization, image information is simply stored and added without additional technical components. Its technical characteristics make it possible to process variously.

Mechanical camera devices that cannot perform digital or signal processing of images at present are incompatible with digital devices based on completely new compression software technology, video media technology, semiconductor technology, and interface communication technology. There is an inherent problem that cannot be overcome in grafting digitally.

In order to solve the above problems, the digital film camera module of the present invention has a chipset circuit and a direct semiconductor circuit modularized in an existing film box, and should be configured with the same size as a conventional film, and an imaging sensor and a lens In order to match the focus of the lens, a separate lens must be attached to solve the exact focus problem, and the lens part and the protruding part can be removed if necessary.

In addition, it must be able to control the digital film by detecting the operation of the mechanical camera to precisely adjust the exposure value and to operate correctly with the existing camera.

As shown in FIG. 2, the imaging sensor 6 uses a charge coupled device (CCD) or a CMOS, and is an integrated lens of a phototransistor which receives light from an existing mechanical camera and converts the light into an electrical signal. Reacts according to the intensity and ratio of light incident through it.

The continuous analog signal output from the image pickup sensor continuously receives electrical signals collected according to the intensity and ratio of light output from the image pickup sensor through the ADC chipset 7 and converts them into digital signals. The image compression chipset 8 performs color correction and gamma value correction on the data of the captured image while compressing the size of the data to a certain capacity so that the data can be easily stored.

In addition, the microcomputer chip 9 controls the serial communication and control of the ADC chipset and image compression chipset, and controls the RS232 port and the RS422 port of the Macintosh in general, and the flash memory of the digital film device. The stored image data is transmitted to a computer having respective RS232 and RS422 ports. The serial communication is performed asynchronously through the serial communication unit 10.

The battery unit 11 is located at the bottom of each chipset unit in the digital film device and supplies power to the digital film device.
