Notes on the Camera Operations
1. If a Frame rate decrease.
Frame rate may decrease depending on your shutter settings.
a.When a series of images is output, the instant when the exposure time is shorter than one frame, and the exposure time setting is shortened using the shutter.

b. When the shutter is set to Auto, the instant when the exposure time decreases to match the light coming in. (Dark tLight)
In either cases, the camera tends to skip 1 frame image, resulting in a decrease in the frame rate. Keep this in mind when using an application that switches exposure time frequently.
c.With a long exposure
In long exposure mode, the exposure time is set longer than the image transmission cycle. In this case, frame rate decreases according to the exposure time.
2.When using Trigger mode
When this camera is set to accept a trigger at the fastest possible timing, it can accept overlap of the next trigger signal in the midst of video transmission. For this reason, a trigger inhibition period is not available. Thus, if a trigger signal is input before the CCD can change to the state where it can accept exposures, multiple exposures can occur, and it cannot capture the correct image. Make sure that the following conditions are met when the trigger is activated.
(However, partial activation can be used if the following conditions are exceeded. Refer to the table on pages 35 and 36.)
TT
Mode 0: timing after the exposure set by the parameter is finished
Mode 1: at the trailing edge of the trigger pulse
: T≥1/30 sec |
3. When AE is not available.
The camera loads the AE function that controls Gain and Shutter automatically. However, the function works properly in the Normal mode only.
When other modes are set, activating the AE function is possible, however, normal operation of the function is not guaranteed.
In Trigger
4. On the sensitivity in Binning mode
In the Binning mode, the vertical signal is factored in, so the sensitivity is doubled. The frame rate is also doubled (the frame cycle is halved), but if the shutter is set to off, the exposure time is halved, and so this effect is canceled out. On the other hand, when the shutter is on, the effect of this inclusion appears, and the sensitivity increases. So when setting the exposure time in the Binning mode, take this into consideration.
