Page 7: Operating Instructions Hardware
3 OPERATING INSTRUCTIONS HARDWARE 3.1 Set up hardware Connect the power cord to the power supply on the side of LED-Panel V4. Connect the power supply to electricity. Switch on LED-Panel V4 by setting the power switch to “I”. The power switch is located beside the power supply. -
Page 8: Trigger Mode
The LED-Panel V4 can be operated manually or via software (USB interface). The downside of using USB with the LED-Panel V4 is that due to controller limitations the maximum speed is limited to 200 μs (5 kHz). Therefore the device provides a switch that allows switching the USB connection on and off. -

Page 12: Shutter Lag With Autofocus Time
Measurement methods Example LED-Panel settings: Operating mode TRIGGER EXT Exposure time (1/x s) 1/10 s LED No. 2 is lit up (Figure 2): Shutter lag is 0.2 seconds (2 * 1/10 s) 4.2 Shutter lag with autofocus time The LED-Panel is used in TRIGGER EXT operating mode and a micro switch is connected. Two pictures are taken and the shutter lag is calculated. -
Page 13: Exposure Time
Measurement methods Example LED-Panel settings: Operating mode TRIGGER EXT Exposure time (1/x s) 1/10 sec Shutter lag without autofocus time: LED No. 2 lights up → 0.2 s Shutter lag with autofocus time: LED No. 32 lights up → 3.2 s Autofocus time = 3.2 s - 0.2 s = 3 s 4.3 Exposure Time Exposure times of cameras can be measured with the aid of the LED-Panel. -

Measurement methods Figure 6 Figure 5 The frequency of the LED-Panel does not match The frequency of the LED-Panel matches the the frame rate of the camera (flickering LEDs) frame rate of the camera (LEDs glow permanently) 4.5 Speed of multi shot mode The speed of the multi shot mode of cameras can also be measured with the aid of the LED- Panel. -
Page 15: Rolling Shutter Speed
Measurement methods Example Camera exposure time: 1/250 s LED-Panel settings: CONTINUOUS, exposure time 1/10 s Each time the LED has moved three places forwards between the consecutive images. With LED-Panel’s frequency set to 0.1s this means the multi shot mode has the speed of 0.3 s per picture (i.e. - Page 16 Measurement methods For software based rolling shutter analysis we recommend two LED-Panels in “Exposure Time” mode, one in the top left corner and one in the bottom right corner. For detailed information on how to set up two LED-Panels with you device under test, please see the following two infographics.

Figure 17 In the “Analysis tab” (Figure 17) you can choose the measurement method and the frequency. The set frequency is used to calculate the time shown by the LED-Panel in your images. For further details on how to measure different camera timings please refer to chapter 5 and ISO 15781. -
Page 21: Iq-Trigger
Operating instructions software The slider Display brightness adjusts the display brightness. This might be helpful to adjust the exposure time of the camera correctly for specific testing conditions. For example if you perform test under low light conditions and use the automatic exposure mode of your camera. Without dimming the display of LED-Panel the bright display light can influence the exposure of your camera. -
