| 摘要 |
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.
