How to get image in PNG format (or other but without any compression)?

[EuroFlock]

Is our Tessel camera module (camera-vc0706) support any other picture formats instead JPG? If yes - how to?

[jon]

The Tessel camera module only supports JPEG images but you can run a remote server that converts to PNG using this Node library. Depending on your use case, I don't recommend running that library directly on Tessel because it will be really slow.

Do you really think that the distorted image by compression makes sense to convert to another format? After all, the quality did not improve! Am I wrong?

No, converting a JPEG to PNG will not improve its quality. You can, however, adjust the compression level.

As I see my Windows 8.1 can open pictures ONLY with default (0.2) compression in 'vga' resolution. Pictures are bad! And why this bad pictures are flipped? Did you not know what you sell? Other pictures with different compression are broken. What I did wrong?

@EuroFlock, if you're getting corrupted images from the camera module then the most likely issue is a flaw in the camera unit we sourced. Please email support@technical.io and we'll get a new module to you.

No, I think all you camera modules are same)) Pictures are bad because have small resolution and included compression! I can not switch off this compression... And I think (like in forum written) nobody can it. Can you change Tessel firmware for possibility get RAW picture without compression (bmp, png, etc.)?

It's not the Tessel firmware, it's another chip (VC0702), that we do not have the ability to change. Yes, it's a low-res camera with a very small sensor; don't expect results like your DSLR.

We are addressing this on Tessel 2 by using off-the-shelf USB webcams so you can choose one that meets your image quality needs.
