Assignee: nan
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A system comprising
a camera array,
wherein the camera array comprises multiple cameras with each camera configured to capture images of a portion of a sample,

an illumination source,
wherein the illumination source comprises one or more radiation sources configured to provide one or more illumination patterns to the sample,

a moving mechanism,
wherein the moving mechanism is configured to move the camera array, the sample, or an element of at least a camera of the multiple cameras,

a processing module comprising a processor,
wherein the processing module is configured to process the images captured by the multiple cameras,
wherein processing the captured images comprises detecting features of interest on the captured images based on an input,
wherein processing the captured images further comprises calculating focus measures for the detected features of interest, with each focus measure calculated based on a degree of image focus of a detected feature of interest,
wherein processing the captured images further comprises determining individual cameras in the camera array for image capturing after a refocusing process, with the individual cameras determined based on numbers of detected features of interest per camera in the camera array,
wherein processing the captured images further comprises determining a focus distance for the moving mechanism in the refocusing process, with the focus distance determined based on the focus measures of the detected features of interest,
wherein the focus distance and the individual cameras are determined by an optimization process configured to maximize a number of the detected features of interest that are in-focused after the refocusing process while minimizing a number of the individual cameras used to generate the in-focused features of interest after the refocusing process,
wherein the processing module is configured to communicate with the moving mechanism for refocusing at least the minimized number of the individual cameras on the sample to bring into focus the maximized number of the detected features of interest,
wherein the processing module is configured to analyze new images captured by the at least the minimized number of the individual cameras after refocusing for generating a statistical characterization of the sample based on the analysis of the features.
