Abstract: In an aspect of the disclosure, a method, a computer program product, and an apparatus are provided. An apparatus determines whether a vision-altering object is present between the apparatus and at least one eye of a user. The apparatus identifies the vision-altering object as corresponding to a previously characterized object in response to determining that the vision-altering object is present between the device and the at least one eye of the user. The apparatus adjusts an image displayed at the apparatus based on one or more characteristics of the previously characterized object. Accordingly, the presence of the vision-altering object is compensated to allow the user to perceive an image that is closer to the image despite the presence of the vision-altering object.

Abstract: A printing system includes a first module configured for capturing an image of a target printer test page including a plurality of color patches and configured to provide color data for each color patch; and a second module configured for generating a color modification based on the color data for each color patch of the target printer test page and color data for a reference printer, wherein the target printer is configured to print images converted using the color modification such that an output of the target printer substantially matches an output of the reference printer.
