I am trying to make a term for a function equipped on an image sensor.(adsbygoogle = window.adsbygoogle || []).push({});

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.

Is 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.
