I would be very grateful for futher information
From the beginning... the i3 Stores the CSV file after the IR and Visual Snapshot. The "don’t move" popup disappears after saving the Visual image. So a few seconds after the popup is gone, the Smartphone is storing the CSV image. If you get Images in less than 5 Seconds its possible, that your image data will be truncated.
Previously the Camera stores in the CSV file a 4x4 "low Res" Temperature map. This was 384x288 temperature Values, but in 4x4 blocks the temperature was the same. After the Temperature Map a byte map follows, there was 384x288 intensity Values in byte range (0-255).
In Version 1.3.x the Temperature map was read to acquire the highest and lowest temperature. The following Byte map was used to create the full image. The translation was simple... min byte = min Temperature and max byte = max temperature.
If the following byte map was missed, the Temperature map was used to create the image.
Since android app version 17 (it was December or November if I remember right) the Temperature map was stored in 1x1 instead of 4x4. The Thermovision 1.3 still gets the Byte map if found. So if you remove the byte map in your CSV File, you get the same image as you get in the 1.4.x Version.
Now in the Version 1.4.x you have the option: "read only TempMap" and this was enabled by default. Just uncheck this Option, and you get the image from Byte Map.
Your image is a nice sample... I never get differences like that before.
Anyway, I just can work with the values I get from the Camera. So if you camera stores a "strange distortion", I can just show you that.
Additional, as noted before, the byte map was translated in relation to the temperature Map. Because this, min and max are the same, but values between can be different. So better use the "read only TempMap" for accurate temperatures.
But the "strange distortion" is interesting, I never noted with my camera before, but I also don’t try to save while moving the camera. For me it looks like the App stores while the live stream delivers new data from the Camera.
I think we should tell i3 about this issue...
If you want to compare the 2 Image frames, you should uncheck Menu->Options->"Use Settings from File".
This will not remove all measurements if you read the next image.
I should improve this next time.
Anyway, thank you for your sample pictures.
Joe-C is a manual temp range possible ?
I guess you mean while USB Streaming right?
Each of the Stream Cameras (Seek Thermal, DIY-Thermocam and Thermal Expert) has a normally checked option "Autorange" or "Autoscale". Just uncheck this option and the Scale will not be affected by a new frame and you can set it yourself.
