Learn English – Term to express a range of fluctuation

technicalterminologyword-choice

I am trying to make a term for a function equipped on an image sensor.
The term is to express "the upper limit of fluctuation allowance in image size which is specified in %"

The value of percentage does not express the ratio of the enlarged image size compared to the original image size, so for example, 150% does not mean that the sensor will only detect a 150% bigger image to the original image.

Instead, it is to express the range of percentage of size fluctuation for sensor to accept to detect the shape (image) which makes 150% to mean that the sensor will detect an upscaled original image in all upscaling rate from 101% to 150%, such as a 102%, 117%, or 142% bigger image to the original image.

Does any of the followings describe the concept well?
If not, what is the problem?

  • Maximum size fluctuation allowance percentage
  • Maximum size volatility allowance percentage

Or,

  • Size fluctuation allowance percentage upper limit
  • Size volatility allowance percentage upper limit

Or, maybe "percentage" better be "rate"?
Also, all of the candidates seem redundant. Any term to combine some words?

Thank you in advance.

Generally there is an argot associated with items of a technical nsture. You're not the first, I'd suggest, who has come up with an image sensor. A useful port of call is to look at the technical reports that go along with image sensors to see how manufacturers are already referring to such 'fluctuation' ranges ...
