Analysis

Video Waveform Display GeneratorModel 303

This unit generates a waveform displayof the intensity underlying a white verticalcursor within a video image . The wave-form is superimposed on the left side ofthe video image . Positions along thedisplay's vertical axis correspond to posi-tions along the cursor. Positions along thedisplay's horizontal axis represent inten-sity increasing from left to right . The cur-sor is shown as a white vertical line andcan be positioned throughout 90% ofthe image .

Video Analyzer Model 321The Model 321 adds several capa-

bilities to the Model 303's intensityanalysis function (described above) . Thisinstrument dis-plays both verti-cal and hori-zontal cursorsand provides agrating for thewaveform dis-play. The horizontal cursor is useful to more accuratelydetermine precisely which image featurecorresponds to points along the wave-form display . The vertical cursor can beslanted, left or right, to better analyze aparticular object . Additionally, the 321generates DC voltages proportional tothe image intensity at the cursors' inter-section and the X and Y positions of theirintersection . A scan function can moveeither cursor at a controlled rate enabl-ing a chart recorder to produce a copyof the intensity profile along either cursor.The 321 has many applications . It is

used in biological research for measure-ment of growth and size of tissue and asa real time video densitometer It mea-sures light level uniformity and concen-tricity in fiber optics . Manufacturing usesinclude quality control of video cameratubes, light emitting diodes, and laserbeam energy profiles .

Video Integrator Model 310AThis unit produces a DC output voltage

proportional to the overall intensity withina selected region of the input video signal .The analyzed region is rectangular, var-iable in both size and position . The DCoutput voltage may be displayed on ameter or used to directly control aprocess .Applications include environmental

or process monitoring of activities involv-ing fog, smoke, dust, or other diffusedsubjects .

The Video Contrast Enhancer Model 605. An originalimage is at left. Shading correction, contrast stretch-ing, and inversion produced the more useful imageat right.

Video Motion Analyzer Model 633The Model 633 produces a DC voltage

proportional to the horizontal position ofa high contrast object in a selectable por-tion of a video signal . As the edge of anobject of interest tends toward the rightside of a video image, the 633's outputvoltage increases . Researchers havefound the 633 useful for monitoring indi-vidual heart cell motion .

Video Position Analyzer Model 635The Model 635 provides a digital

horizontal position readout of a high con-trast object in a selectable region of avideo image. The region is variable inwidth and position and its height can beselected at 4 or 8 lines of the raster.

Video Micrometer Model 305The Video Micrometer provides a

means to measure dimensions of objectsseen by a video camera . It includessignificant con-trast expansioncapability to im-prove the visibil-ity of the edgesof low contrastfeatures .

To take ameasurement, the user positions two ver-tical cursors about the feature of interest .A front panel display indicates thedistance between the cursors . The 305'swaveform display, similar to that of theModel 321 (see page 3), significantlyassists the user in precisely positioningthe cursors for accurate, repeatable mea-surements . The 305 is used extensivelyin video microscopy systems for semicon-ductor research, development, manufac-turing, and quality control .

Video Caliper Model 306The Model 306 provides a means to

take horizontal and vertical measurementssimultaneously.

To take ameasurement,the user posi-tions a rec-tangular boxabout the fea-ture of intereston the video monitor. Two front paneldisplays indicate the dimensions of thebox . The box may be positioned over andencompass up to 80% of the image .

Video Contrast Enhancer Model 605This instrument provides contrast ex-

pansion, shading correction, and inver-sion . The contrast enhancement functionimproves visibility of low contrast featuresby stretching a portion of the input video'sgrayscale to fill a larger grayscale rangeat the output . Shading correction can im-prove an unevenly illuminated image. Theinversion function, by creating a negativeimage, can improve visibility of cracks,pits, scratches, and defects on highlyreflective surfaces .

Video Quantizer Model 606HThe Quantizer synthesizes a color pic-

ture based on different shades of gray ina monochrome input signal . Sixteenthreshold controls can be set to ''slice''the input video signal, and sixteen setsof color controls vary the color assignedto each ''slice'' level . An eight level ver-sion, the 606G, is also available .

Video Digitizer Model 270AThis instrument digitizes high resolution

images of primarily non-moving subjects .

It is available with 512 x 480, 2048 x 480,or 1024 x 1024 visible pixel resolution . Allhave 256 shades of gray.The Model 270A displays a cursor to

show the location of pixels being en-coded . A waveform, displayed on themonitor screen, shows a brightness pro-file, facilitating quick and accurate grayscale level setting without additionalequipment . The unit interfaces with mostmini or micro computers .

Sync Stripper Model 302-2Given a video input, this unit provides

video synchronization pulses . Compositesync, composite blanking, horizontaldrive, and vertical drive outputs are de-rived from the loop-through video input .The Model 302-2 is a very cost effectivealternative to a genlockable syncgenerator.

Video Test Generator Model 615The Model 615 generates video test

signals for evaluating geometric, gray-scale, and resolution characteristics ofvideo equipment . Available in two ver-sions, the 615 requires external sync,blanking, and drive inputs, the 615Agenerates these pulses and providesthem as outputs .

Digital Display GeneratorModel 109A/13The Model 109A superimposes a

number on a video display correspond-ing to the value of an analog input volt-age. Designedprimarily for usewith ColoradoVideo Models310A, 321, 635A,it may also dis-play voltagesfrom -5 to +5

' --VDC derived from other sources .The Model 109B superimposes a

number on a video display correspond-ing to the value of 3 1/2 or 4 1/2 digit BCDinput . Designed primarily for use withColorado Video Models 305, 305A, 635,it may also display values from otherequipment providing BCD ports .

Asynchronous Frame StoreModel 495

This "wrap around'' grabber capturesevents that cannot be synchronized witha video camera . After it is triggered, a

typical frame store waits for the camerato start scanning a new frame before com-mencing storage . This delay means thatas much as 33 milliseconds can elapsebetween trigger and storage commence-ment . Upon trigger, the Model 495 com-mences storage when the camera startsa new horizontal line . It continues storageuntil an entire frame is captured . The max-imum delay is 63 microseconds .

Video Multimemory Model 499The Model 499 sequentially freezes,

stores, and reproduces 16, 32, or 64 im-ages . Each frame may be selected forviewing, or images may be sequencedforward or backward at normal speed.Slow motion playback and time lapserecording are also featured .

FREQUENCY FOLLOWER MODEL FF-1

HIGHLY ACCURATE FREQUENCY FOLLOWINGHIGHLY ACCURATE ENVELOPE FOLLOWINGWIDE VARIETY OF REMOTE CONTROLLED PERFORMANCE FEATURESAUTO-LOCK MODE FOR EXACT SOURCE/VCO PITCH MATCHINGRACK MOUNTABLE CABINET WITH REMOVABLE BRACKETS

The POLYFUSION model FF-1 Frequency Followeris one of the most significant developments in thefield of synthesizer controllers in recent years . Thisinstrument enables you to accurately control asynthesizer with your flute, your voice, or anymonophonic instrument you choose. Unlike otherfrequency followers, the FF-1 is not committed foruse with only one specific instrument . This meansthat you can use the instrument pick-up you alreadyhave (without modification) or even sing into amicrophone and obtain accurate pitch control voltagesevery time . That's right, it can follow the mostcomplex waveform and reliably extract the funda-mental frequency without being confused by over-tones . The FF-1 also contains an envelope followerwhich supplies an additional control voltage for asynthesizer VCA, one which is proportional to theloudness and articulation of the input signal . In thisway, the envelope of an acoustic instrument can bematched by the synthesizer sound . Also, gate out-puts are provided to activate a synthesizer envelopegenerator each time the input signal exceeds a pre-determined loudness level . This level, called GATETHRESHOLD can be varied with a panel control .

In short, the instrument you now play becomes acomplete synthesizer controller -- a controller withmore flexibility, range, and responsiveness than thekeyboard which the synthesizer has relied on forso long .

The FF-1 Frequency Follower has several specialperformance features which enhance its alreadyformidable capabilities :

The AUTO-LOCK function compares the pitch ofthe audio signal with that of the VCO which is beingcontrolled by the FF-1 . Based on this comparison,the AUTO-LOCK corrects the pitch control voltagefrom the FF-1 to cause the VCO to exactly matchthe pitch of the input signal . The AUTO-LOCKwill even correct for small errors in the VCO scaling!

The INTERVAL feature allows you, at any time, toinstantly change the musical interval between yourinput signal and the VCO being controlled by theFF-1 . This interval is tuned with the INTERVALcontrol and is selected by means of a footswitch .
