It would have to be an interpolation algorithm that doesn't add or remove signal information. Everybody uses approximations for efficient hardware utilization. I wouldn't consider that admissible.
Btw, this isn’t a “right wing” issue. Political “liberals”, to their credit, have been saying as much for years, pointing out that closed source software has huge problems in court.
As it stands, the defense has a right to force the prosecution to either get an Apple employee to testify in court, or use a linux machine, gimp and a CS expert to explain what gimp is doing.
EDIT:
sorry I read comment Im replying to as “I wouldn't consider it inadmissible”. I txted this while dozing off.
The prosecutor literally tried to infer an action from a single pixel. That’s BS and everyone in this forum has the technical ability to recognize this. A single pixel from a low light environment (therefore noisy)?
