Page 70: Overlap Exposure And Non-Overlap Exposure
Mercury U3V Cameras User’s Manual The implementation process of electronic rolling shutter sensor is as shown in Figure2- 15, different from the global shutter, electronic rolling shutter exposures from the first line, and starts the second line exposure after a row period. And so on, after N-1 line, the N line starts exposing. When the first line exposure ends, it begins to read out the data, and it need a row period time to read out one line (including the line blanking time). - Page 71 Mercury U3V Cameras User’s Manual camera is triggered, it begins to integrate and when the integration is over, the image data will be read out immediately. The MER-U3x series camera supports two exposure modes: overlap exposure and non-overlap exposure. The user cannot assign the overlap exposure or non-overlap exposure directly, it depends on the frequency of trigger signal and the exposure time.

Mercury U3V Cameras User’s Manual Table2- 6: Global Shutter camera models Because all the lines of Electronic rolling shutter camera are exposed not at the same time, it is difficult to use flash light. The strobe is light only during all the lines at the same time exposure and no photons into the sensor at the other time, the camera can get consistent brightness image. -

TestPattern The MER-U3x series camera supports three test images: gray gradient test image, moving diagonal gray gradient test image, and static diagonal gray gradient test image. When the camera captures in 10bit mode, the gray value of test image is: the pixel gray value in 8bit mode multiplies by 4, as the output of pixel gray value in 10bit mode. - Page 83 Mercury U3V Cameras User’s Manual Image rolling direction Figure2- 25: Moving diagonal gray gradient test image SlantLine In the static diagonal gray gradient test image, the first pixel gray value is 0, the first pixel gray value of adjacent row increases by 1, until the last row.
