`
`Why should a computer camera cost more than the computer???
`
`The EDC-lOOO, built by ELECTRIM (ELECTRonic IMaging) Corporation, is a compact,
`digitally controlled/digital output television-like monochrome camera designed and built in the
`United States specifically for the computer technology market. The EDC-lOOO (see Figure l) is an
`inexpensive alternative to a standard TV camera attached to special analog—to—digital (A/D) and
`frame—grabber circuitry. The result is the most cost effective way to put image data into a computer
`and let your computer go to work directly on the data.

`
`The EDC-lOOO has applications wherever the power of the computer can be applied to
`image data:
`.
`
`security (surveillance);
`telecommunications (picture phones);
`office automation (document imaging);
`desk top publishing;
`factory automation (robot/machine vision);
`industrial inspection (pattern recognition);
`education; computer—based commercial and graphic art;
`picture databases; and
`astronomy.

`
`The main features of the EDC—1000 are summarized in Table 1, The unit operates fully
`under computer control, and is totally computer compatible. No additional AID, D/A, or other
`hardware is required. The BBC 1000 significantly reduces the complexity of digitizing stationary
`or moving images. A single half-size plug-in card will permit any IBM PC, XT, AT, PS/S Model
`25 or 30 or compatible computer to control the camera with simple commands. The camera uses a
`charged—coupled device (CCD) detector for the utmost in reliability, ruggedness, high sensitivity,
`and geometric fidelity.
`
`Everything about the EDC-lOOO is easy. Power is derived from the computer bus itself._
`All timing and video signals as well as power are carried on a single multiconductor cable which
`connects the camera to the computer. The computer controls exposure time and frame scanning
`time. Under computer control, multiple images can be integrated to impr0ve the signal-to—noise
`ratio where low light level conditions are encountered. The EDC-lOOO incorporates asynchronous
`scanning techniques, making it possible to trigger the frame reset and scanning to an external
`event. Output from the camera system is an 8—bit digital signal corresponding to the quantized
`value of brightness at serially sampled spatial data points (256 gray levels).
`
`The camera requires an IBM-PC or compatible computer with only a single floppy disc
`drive, 256K RAM, a free expansion slot to install a half size card, and either PC-DOS or MS-DOS
`version 2.1 or higher. Either color or monochrome monitors can be used. Software furnished
`with the EDC—lOOO on a 5.25-inch diskette supports CGA, EGA, MCGA, VGA and Hercules
`adaptors.
`Images can be saved in either TIFF or PCX (PC Paintbrush) format for compatibility
`with desktop publishing software. The software to read and control the camera is written in ”C"
`and assembly language; linkable routines that are compatible with C, Pascal and BASIC are also
`provided. The EDC-lOOO continuously acquires gray scale images at up to 30 frames per second.
`Speed will vary depending on exposure time, graphic display mode, and computer clock speed.
`Featuring a solid state image sensor, the camera has the following properties:
`
`The ECD- 1000 digital camera is shipped with: lens, cable, interface hardware, software on
`a 5 1/4 inch diskette, owner's manual and one year warranty. The unit can be purchased direct
`from ELECTRIM at the address above (or phone us at 609-799—7248) for $400.00, plus $6.00
`shipping and handling charge. New Jersey residents must add 6% sales tax. Please mention this
