1) 2.5 mm audio cable has 2 wires. Which are connected to what? 2) Do you trigger camera from the external source, use camera trigger output or use external signal to log in the camera On Sun, 16 Dec 2018 18:35:17 -0800 Winston Zhang wrote Hi elphel. 1. The 2.5mm audio line connect to the trigger generated cable(can output the 5v pulse voltage). 2. The trigger signal can be controlled by software. So We can stop it. 3. The parameters can not be refresh when I change the trigger page parameter(many many times). But may be it works some time. So I load the parameters which was saved some day. This is a big problem, it waste much time to save parameter. --- Best Regrad!

Hello, In the link you used the internal trigger generator is working and is routed out to the sync cable (which is probably self-looped - input and output wires are connected): Try: *1.* Set TRIG_OUT=0x0 to stop internal pulses at the sync cable output: # old link: http://192.168.0.9/parsedit.php?sensor_port=0_CONDITION=0x9_OUT=0x66555_PERIOD=1=4 # new link: http://192.168.0.9/parsedit.php?sensor_port=0_CONDITION=0x9; > *TRIG_OUT=0x0*_PERIOD=1=4 *or * *2.* If the sync cable inputs and outputs connected. Disconnect the wires from each other and apply your trigger source: signal or "+" - to Black wire, ground or "-" - to Green wire. Please, check the wire colors and pinout here <https://wiki.elphel.com/wiki/103891>. Let us know if that worked. Thanks. I'll update our docs to make them clear.

Hi, Andrey! Thany you for your patience to answer our questions! I have some new questions about external trigger. When I set the trigger parameter as the page http://192.168.0.9/parsedit.php?sensor_port=0_CONDITION=0x9_OUT=0x66555_PERIOD=1000=4,<http://192.168.0.9/parsedit.php?sensor_port=0_CONDITION=0x9_OUT=0x66555_PERIOD=1=4,> and I made the trigger board pulsing out the signal(10HZ), I found we could get 10 images. But I stopped the trigger board signal, I also could update the image(10hz). I wanted to konw that how can I test the external trigger signal work? Because when i stop external source trigger signal, it could receive images too. --- Best Regrad!

Hello Winston, You may try to delete all autocampars*.* files from /etc/elphel393 in the camera and reboot. Your saved settings will be lost - you may first copy autocampars*.xml somewhere else or just use *.backup files if you did not reboot too many times since you've got that problem. If after boot camera will not find those files, it will create default ones. Andrey On Sun, 15 Apr 2018 19:59:09 -0700 Winston Zhang winston.zh...@blacksesame.com.cn wrote Hi Andrey!

Allen, ~/.imagej/Eyesis_Correction.xml is not really needed - it just hides/reveals some experimental buttons on the interface This is the contents of such file: ?xml version="1.0" encoding="UTF-8"? !DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd"; properties commentlast updated Thu Sep 08 14:09:47 MDT 2016/comment entry key="ADVANCED_MODE"False/entry entry key="DCT_MODE"False/entry entry key="MODE_3D"False/entry /properties result.jpg looks correct. It should be super-contrast as it is linear, so it CAN NOT be saved as JPEG - it needs either 16 bits or 32 bit TIFF as when you save it from imageJ (save as tiff). And it is "monochrome" - each pixel corresponds to the sensor pixel value. For you application I would recommend to use just green subchannel (checkerboard pattern, half of all pixels) - in that case you do not need to have aberration correction. Your plots for gamma seem correct too, to be sure I need to look into the code again - I wrote that part several years ago. Gamma is not changed automatically in the camera, but you may change it using one of the interfaces - camvc of just parsedit. In addition to the power (0.57) there is another parameter - dark level - the sensor adjusts its ADC to have output level of 160 (on 4096 scale) or 10(256) for the complete darkness, so-called "fat zero". Gamma is applied inside the FPGA and parameters are saved in the Exif header, so for processing it is possible to "undo" gamma and restore linear scale.

Does gamma value remain unchanged when camera works ? Who realize this gamma mapping, sensor or ISP? 2. When gamma0 = gamma1 = gamma2= gamma3 = 0.57, gamma_scale0 = gamma_scale1 = gamma_scale2 = gamma_scale3 = 1024, gamma mapping is Vout = a*Vin^gamma, a = 2.23 gamma = 0.57 , is it right? If not right, could you tell me the right?

Re: [Elphel-support] 答复: 答复: 答复: 答复: 答复: sync stereo with lidar
Hello Winston, Tomorrow Oleg will try to reproduce your settings - so far we did not have such problems. BTW, you can set same parameters on multiple ports simultaneously, using "Broadcast Mask" (hex number 0..f) Port 0: 1 port 1 - 2 port 2 - 4 port 3 - 8, So broadcast mask 3 will set the same mode on ports 0 and 1. About bits I tried to explain in the previous messages and the "How many bits..." in the article. Sensor provides 12 bits, and each bit is important in the shadows. But not in the bright light because of the shot noise that is caused just by the fact that each pixel can store only integer number of electrons. And so while all bits are important, there are not 4096 meaningful levels for each pixel, but significantly less (see "How many bits..."). Gamma conversion uses non-linear scale to represent pixel values with steps proportional to the shot noise (steps are smaller). The gamma conversion parameters are saved in the Exif header of the JP4 file, and if you open files with ImageJ plugin, it takes care of the Exif data and restores linear data proportional to the pixel raw values, then you can save it as 32-bit Tiff file. Andrey Hi, Andrey I met a new question. I set ‘Color’ parameter with the five(it could get the jp4 format image)on one camera, and this camera image format was converted. But when I set the other one, this camera image format was not converted. Please help me test for it. Another question What is the raw jp4 format image with 100% compression bit wide? I read it and the result show the bit wide is uint8. But you web shows that the bit wide is 12bit. Best Regrad!
