August 30, 2001 TM-250 Miniature CCD Camera Operation Manual 1 Introduction 1.1 Product Description The TM-250 is an inexpensive, high-quality camera that meets a variety of application requirements. Featuring an advanced Hyper-HAD1 interline transfer 1/2" CCD imager, this miniaturized highresolution camera offers many standard and optional features at a very affordable price. A CCIR-format model, the TM-260, is also available. 1.
PAGE 8
Page 2 Introduction Because the CCD is highly resistant to image burning, the camera may be exposed to bright objects for a long period of time. Because a “smear” phenomenon may occur when shooting a very bright object, we recommend an infrared cutoff filter to obtain a clear picture (optional). • AGC/MGC selection, manual gain control and gamma adjustment These adjustments, which are particularly important in vision system applications, are externally adjustable via switches on the rear plate.
PAGE 9
Page 3 Introduction 1.4 Applications The miniature size of the TM-250 camera eliminates the need for a remoted imager camera in all but the most confined spaces. This camera fits easily, both physically and functionally, into all types of machine vision, automated inspection, and related applications. Other uses include remotely piloted vehicles, miniature inspection devices, surveillance, microscopes, and medical equipment. 1.

Connect the output from the camera to the input of your monitor, VCR, or switching device. The input of the monitor should be balanced for 75Ω termination. Standard RG-59 type coaxial cable should carry a full video signal for up to 500 feet.

Page 11 Operation 3.1.3 Field and Frame Modes The standard factory setting for the TM-250 camera is FRAME MODE. The field and frame integration mode is selectable using the switch on the rear panel of the camera. The frame integration is used to separate all CCD pixels. The exposure of Odd and Even fields generates the full frame image shown in the figure below.

Page 12 Operation 3.2 External Sync The TM-250 can accept external sync from an external sync generator or frame grabber. Its input specifications are: Internal/External auto switch fH=15.734 KHz ±5%, fV=59.95 Hz ±5% Note: FIGURE 3. The TM-250 has a one (1) horizontal line delay between the input VD signal and the output video. If external vertical drive (VD) is applied to the camera, it may cause the video output to be delayed 1 HD (1 HD = ~64.0 µs).

Page 15 Operation The following four asynchronous shutter modes are available: • Strobe Asynchronous Shutter Mode • Pre-Reset Asynchronous Shutter Mode • Post-Reset Asynchronous Shutter Mode • Pulse Width Asynchronous Shutter Mode Please contact PULNiX for timing charts of various asynchronous shutter modes. 3.3.4 External Sync Mode TM-250 accepts standard RS-170 external sync, which is defined as horizontal sync (HD) and vertical sync (VD).

Page 16 TM-250 External Signals 4 TM-250 External Signals This section explains how the external signals (VD and HD) and shutter trigger signal (VINIT or TRIG) must be fed in Async Mode operation, Integration Mode operation, and Reset-Restart operation. 4.1 External VD The TM-250 I/F circuit intentionally delays the external VD for two pixel clock period.
PAGE 23
Page 17 TM-250 External Signals 4.3 Width Mode Reset-Restart Operation In Width Mode Reset-Restart operation, the leading edge and trailing edge of TRIG must both be synchronized with external HD. In addition, the duration must be 1 line or longer in one-line step. If the TRIG does not meet these conditions, the exposure time may vary from the position and the field. Figure 7 below illustrates the proper operation with constant 2-line exposure period.

Page 20 Operation Mode FIGURE 11. High-Speed Cyclic Shutter Mode Timing Internal VD DSUB pulse Transfer Exposure Video Out 5.1.3 Trigger Position Reset/Restart Shutter Mode The shutter trigger pulse (TRIG) needs to synchronize with Reset-Restart (EXT VD) pulse. It should be 2 lines or more in width. The leading edge of TRIG pulse produces DSUB (discharge) pulse and starts the exposure. The transfer (read-out) occurs at the 11th line after EXT VD pulse is fed.

Strobe Asynchronous Shutter Mode Timing External HD VINIT Reset Reset Internal VD Strobe Transfer (CCD) Transfer (EVEN) Video Out F2 = OFF F2 = ON 5.2.2 Post-Reset Asynchronous Shutter Mode The operation of this shutter is similar to Cyclic Fast mode. But the exposure starts in sync with an external pulse called VINIT pulse. On the leading edge of VINIT, single discharge pulse occurs and all the photo-charge is damped.

PAGE 31
Page 25 Operation Mode 5.2.3 Pulse Width Asynchronous Shutter Mode Pulse Width Mode Async Shutter enables exposure time to be controlled by the duration of VINIT. The camera operates in the same way as it does Fast Mode Async Shutter or Pulse Width Mode Integration. Unlike Pulse Width Mode Integration, the single pulse of discharge occurs only when the falling edge of VINIT pulse is detected.
PAGE 32
Page 26 Operation Mode time can be less than 11 lines for the TM-250 and 16 lines for the TM-260. If the F2 switch is Up (ON), VSYNC is continuously generated and the camera behaves the same as in High-speed Cyclic shutter operation. When F2 is OFF, VSYNC appears in only the field right after VINIT when F2 is down (OFF). FIGURE 17. Pre-Reset Asynchronous Shutter Mode VINIT Reset Reset Internal VD DSUB pulse Transfer Exposure Video Out TABLE 11.
PAGE 33
Page 27 Operation Mode 5.2.5 Double Pulse Integration Mode Double Pulse Integration mode enables exposure times to be longer than one field. It also works for strobe applications. The camera operates in the same way as it does in Asynchronous Strobe Shutter mode. The transfer occurs only at one field in Field Accumulation mode, or at two fields in Frame Accumulation mode after the leading edge of VINIT pulse is detected.
