1. A method for image acquisition, said method comprising:
- obtaining a preview-frame image;
extracting a first image feature from said preview-frame image;
interpreting said first image feature in relation to a first acquisition factor; and
rendering an overlaid preview-frame image comprising a first cue associated with said first acquisition feature.

Abstract
Aspects of the present invention are related to systems and methods for providing real-time feed-back cues in an image acquisition process. An overlaid preview-frame image may be rendered comprising cues associated with acquisition factors. A cue may indicate whether, or not, an acquisition-factor value falls within a range of acceptable values. Image features may be extracted, from a preview-frame image, and interpreted to determine acquisition-factor values and their acceptability.

25. A method for image acquisition, said method comprising:
-
obtaining a preview-frame image; extracting a plurality of image features from said preview-frame image; interpreting said plurality of image features in relation to a plurality of acquisition factors, thereby determining an acquisition-factor value for each of said acquisition factors in said plurality of acquisition factors; determining, for each of said acquisition-factor values, if said acquisition-factor value is satisfactory; when each of said acquisition-factor values is satisfactory, acquiring a first image; and when, at least one of said acquisition-factor values is not satisfactory, rendering an overlaid preview-frame image comprising a plurality of cues associated with said acquisition-factor values. - View Dependent Claims (26)
