1. In a system for generating an image of at least a portion of an object, a method comprising:
- capturing image data for at least a portion of the object;
identifying a low frequency noise quality in the captured image data for at least a portion of the object; and
using the low frequency noise quality to select a resolution level for generating an image using the captured image data.

Abstract
A method of analyzing image data to determine an appropriate resolution level for image to be generated from the image data. In the method image data can be analyzed to determine a high frequency noise quality and a low frequency noise quality in the image data. These different noise qualities can be used to determine an appropriate resolution for an image to be generated. An apparatus which can execute a method of the invention, is also provided.

11. In an imaging system, a method for evaluating a quality of different resolution levels for viewing at least a portion of an object, the method comprising:
-
using image data to generate an auto-focus curve for a plurality of different resolution levels, wherein the auto-focus curves provide an estimate for a sharpest height in the object;
determining a high frequency noise quality for each of the plurality of resolution levels;
determining a low frequency noise quality for each of the plurality of different resolution levels; and
using the high frequency noise quality for each of the plurality of different resolution levels, and the low frequency noise quality for the plurality of different resolution levels to select a resolution level for generating an image of at least a portion of the object. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
