Here's an analysis of the most relevant prior art for US patent 12250452, based on the citations provided in its "BACKGROUND" section. The claims of US12250452 are referred to as "Embodiments" as presented in the patent's "SUMMARY" section.

Most Relevant Prior Art for US12250452

The patent US12250452 itself highlights several prior art documents in its background section, providing a brief description of their relevance. These are considered highly relevant due to their direct discussion by the patent's inventors.

1. US Patent Application Publication US 2013/0155474 A1

  • Full Citation: US 2013/0155474 A1, "Method and System for Capturing Quality Images of Documents," published June 20, 2013.
  • Publication/Filing Date: Published: 2013-06-20; Filed: 2011-12-16.
  • Brief Description (from US12250452 background): This publication describes providing feedback to a user of a mobile device before capturing an image of a paper document. The feedback includes instructions for adjusting measured parameters. Parameter values can be combined into a group threshold or a total overall quality score. An image is captured by the camera only when this overall quality score exceeds a defined threshold. The system can provide detailed information to help the user take a better-quality image, such as suggesting the user hold the camera steadier if blurriness is detected due to motion blur.
  • Potential Anticipation under 35 U.S.C. § 102:
    • Embodiment 1: This document potentially anticipates the core elements of Embodiment 1, as it describes "computing at least one total quality indicator based on at least two quality indicators" (e.g., combined parameter values into an overall quality score) to "determine whether the photo quality is acceptable" (exceeds a threshold) and "providing a corresponding detailed photo quality feedback" (detailed information and suggestions).
    • Embodiment 2: The concept of "automatically activating the capturing apparatus, once a logical criterion based on said quality indicators is met" is anticipated, as the image is captured when the overall quality score "exceeds a defined threshold value".
    • Embodiment 3: This document explicitly anticipates Embodiment 3 by stating, "The user can be provided detailed information to assist the user in taking a better quality image... The test result messages can suggest that the user hold the camera steadier when retaking the image." This directly aligns with providing "at least one appropriate suggestion from a pre-stored table of suggestions".
    • Embodiment 8: The description of capturing an image when a total quality score reaches a threshold implies "automatic image capturing... once a configured total quality indicator meets a minimum threshold," even if not explicitly stating "without the user pressing a shutter button".

2. International Publication WO 2006/040761 A1 / US Patent Application Publication US 2007/0195174 A1

  • Full Citation: WO 2006/040761 A1, "Image Grade Evaluation," published April 20, 2006.
    • Corresponding US Publication: US 2007/0195174 A1, "System and Method for Image Grade Evaluation," published August 23, 2007.
  • Publication/Filing Date:
    • WO 2006/040761 A1: Published: 2006-04-20; Filed: 2005-10-14.
    • US 2007/0195174 A1: Published: 2007-08-23; Filed: 2005-10-14.
  • Brief Description (from US12250452 background): This describes a system where an interface module allows defining the "scene dynamics" of a captured image, including "image motion speed and motion speed of the subjects." It also enables setting "relative weights" for "captured image attributes" in the computation of a "total image grade."
  • Potential Anticipation under 35 U.S.C. § 102:
    • Embodiment 1: This document anticipates the generation of a "total quality indicator" based on multiple quality indicators (e.g., "scene dynamics," "image motion speed," "motion speed of the subjects") and the use of "relative weights" in its computation.
    • Embodiment 5: The focus on "scene dynamics," "image motion speed," and "motion speed of the subjects," along with using "relative weights" for a "total image grade," is relevant to "quantify video quality" by leveraging quality indicators and their importance.
    • Embodiment 9: By explicitly mentioning "image motion speed and motion speed of the subjects," this document introduces the concept of detecting movement that could lead to blur, anticipating the use of "blur type detection for alerting the user of object movement in a region."

3. US Patent Application Publication US 2009/0278958 A1

  • Full Citation: US 2009/0278958 A1, "System and Method for Auto-Capturing Digital Images," published November 12, 2009.
  • Publication/Filing Date: Published: 2009-11-12; Filed: 2008-05-09.
  • Brief Description (from US12250452 background): This publication describes that "The scoring of a current base image may be based on scores which have been given to previously captured base images. In such a manner, redundant calculation may be avoided."
  • Potential Anticipation under 35 U.S.C. § 102:
    • Embodiment 1: This document anticipates the aspect of "computing at least one total quality indicator based on... its previous image frames" by explicitly stating that "scoring of a current base image may be based on scores which have been given to previously captured base images." This directly relates to using historical data for current image quality assessment.

Due to the broad descriptions of these "other systems" provided in US12250452 and the need for a detailed claim-by-claim comparison for anticipation under 35 U.S.C. § 102, a more in-depth analysis of each patent document would be required to identify specific claim anticipations beyond the general scope. However, based on their titles and typical scope of such patents, they broadly relate to aspects of image quality assessment and processing, which are foundational to the claims of US12250452.
