1. PRODUCT DESCRIPTION Model CS3720F is a separated-type (two-body) B/W CCD camera with an EIA all-pixel-data readout CCD. This model has twice greater driving frequency of CS3710 to achieve fast-speed data-processing. The video output interface of CS3720F conforms to the serial digital bus standard IEEE 1394. 2. FEATURES (1) 1/2 type, EIA, all pixel's data readout square-array CCD In CS3720F, a square-grid-array, all-pixel-data-readout CCD is integrated. This model reads out image-data twice as fast as conventional cameras do. (2) Random trigger shutter function With a built-in RTS (Random Trigger Shutter), the inner CCD starts light-exposure in synchronization with external trigger signal inputs. This function enables this model to capture fast-moving subjects at constant position for precise image processing. (3) IEEE 1394 video output The CS3720F outputs video signal via the serial digital bus standard IEEE1394. The data transfer is made in 40OMbps. Non-compressed VGA format video data (640 x 480) are output in 60fps. (4) Scalable readout segment This camera is fitted with the "scaling" function. With this function, you can specify its readout area in terms of segmental rectangular blocks. As necessary area only is read out, further faster operation is ensured. (5) PC control Basic operational parameters can be manipulated via PC. The camera control interface conforms to IEEE 1394 digital camera protocol standard. (6) Ultra-compact & light-weight camera head The model features its ultra-compact and light-weight camera head, freeing you from your integration-space-problem. In addition, it has an excellent shock and vibration resistance. 3.

6. OPERATION 6-1. GAIN The gain of CS3720F is manually adjustable. The initial factory setting is in 0dB (= rated shooting condition). By manipulating the command status register setting value via IEEE1394 serial bus, you can change the gain value in 256 steps within the range from -10dB through +18dB. Due to the level variation characteristics of the gain control amplifier, incremental gain change amount per step is not uniform. 6-2. Electronic shutter The shutter-speed of CS3720F is also manually adjustable. The initial factory setting is in 1/120s. By manipulating the command status register setting value via IEEE1394 serial bus, you can change the shutter-speed in 8 steps, including 1/120, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/8000, and 1/20000s. 6-3. Random trigger shutter- Under the RTS mode, the camera's inner CCD starts light-exposure in synchronization with external trigger signal inputs, so you can let the camera capture image at any userdefined timing. The RTS is effective in shooting any fast-moving object, or when you are operating more than one camera at the same capture timing. The input pulse under the RTS mode should be as follows; Model CS3720F supports both Trigger Mode 0 and Trigger Mode 1. In addition to the command status register settings as shown above, the RTS mode shutter-speed can be controlled via trigger signal pulse width as well. 4
6-4. Scalable function Model CS3720F is equipped with the sixteen-way split scalable mode function. In this mode, the camera reads out only the user-selected segment of data (= block readout). A screen is composed of horizontal 4 lines and vertical 4 columns, and each unit cell has a 160 x 120 size. You can set the readout segment only in a rectangular block outline. No convex or concave outline selection is acceptable. The scalable mode works only under the RTS operation mode. Under the scalable mode, the user-selected necessary segment only is read out at normal speed, while other unnecessary portion is skipped through at fast speed. If the vertical length of user-cutout segment is short, the trigger width is also short. In contrast, due to CCD operational characteristics, you can't shorten the trigger width even if you cut out the readout segment in a short horizontal length. 6-5. Timing chart (1) Normal shutter mode 5
(2) Random trigger shutter mode TRIG (EXTERNAL INPUT) CCD EXPOSURE (CAMERA INTERNAL) VIDEO DATA (VIDEO OUTPUT) *The camera processing delay time after trigger input signal is approximately 80ns. (3) Random trigger shutter mode (Pulse width control) TRIG (EXTERNAL INPUT) CCD EXPOSURE (CAMERA INTERNAL) VIDEO DATA (CAMERA OUTPUT) *The camera processing delay time after trigger input signal is approximately 80ns. 6
(4) Scalable Each of A, B, C time below is determined by the vertical user-selected cutout position and cutout length. Please refer to the timing chart below. TRIG CCD EXPOSURE VIDEO DATA *The camera processing delay time after trigger input signal is approximately 80ns. *The actual bus output data is B time only. (5) Scalable (Pulse width control) Like (4) above, even when the exposure time is controlled through the width of pulse, A, B, C time each is determined by the vertical user-selected cutout position and cutout length. Each of A, B, C time is same as (4). TRIG CCD EXPOSURE VIDEO DATA *The camera processing delay time after trigger input signal is approximately 80ns. *The actual bus output data is B time only. 7
The interval A, which is the time from the completion of CCD exposure through image output, is determined by the readout start line above. The cutout length has no impact on this time. Table 1: Time from the completion of CCD exposure through video output From 1 st line From 2 nd line From 3 rd line From 4 th line Approx. 1ms Approx. 1.2ms Approx. 1.4ms Approx. 1.6ms The interval B is determined by the cutout length. The cutout position has no impact on this time. Table 2: Video output time 1 st line 2 nd line 3 rd line Approx. 3.75ms Approx. 7.5ms Approx. 11.25ms Trigger disabled time (= No trigger signal input acceptable) after scalable is as shown in table 3 below. The cutout length has no impact on this time.
