AI Technical Summary

Technical Problem

Capturing high-quality group photographs where all participants are in focus remains a challenge due to varying distances from the image capture device, leading to inconsistent clarity, as conventional approaches rely on post-capture image processing that requires computational resources and user intervention.

Method used

An electronic device and method that estimates volumetric parameters for each object in a group, determines relative depths, and optimizes photographic parameters such as focal length, focus, resolution, exposure, and aperture in real-time to ensure all participants in a group photograph are in focus, using a combination of hardware settings and machine learning for image processing.

Benefits of technology

Achieves consistent image quality across varying depths within a single frame by optimizing photographic parameters in real-time, eliminating the need for post-capture processing and user intervention, resulting in a focused group photograph.

Abstract

According to an embodiment of the disclosure, the method for optimizing photographic parameters may be provided. The method may include obtaining an image data, associated with a plurality of objects, wherein each of the plurality of objects comprises a face. The method may include estimating a plurality of volumetric parameters corresponding to each of the plurality of objects. The method may include determining, with respect to a reference object of the plurality of objects, relative depths corresponding to each of non-reference objects, based on the estimated plurality of volumetric parameters. The method may include determining sets of photographic parameters corresponding to each of the non-reference objects, based on the determined relative depths. Each set of photographic parameters may be hardware settings determined to focus on at least one of the reference object and each of the non-reference objects.
