Abstract:
1. A system for determining optimal timing for capturing an image of at least one face having facial sub object, upon fulfillment of predefined capturing requirements, the system comprising: an interface module; and a processing module, wherein the interface module obtains from a user, a plurality of capturing requirements, wherein the processing module repeatedly obtains over time, a sequence of images of the at least one face, from an imaging apparatus, wherein the capturing requirements comprise both static characteristics relating to facial expression and head orientation of the at least one face, and dynamic characteristics relating to changes in a position of the at least one face the facial sub objects thereof, wherein the processing module repeatedly compares the static characteristics relating to facial expression and head orientation of the at least one face in a particular obtained image with corresponding static characteristics relating to facial expression and head orientation of the at least one face in the capturing requirements, and instruct the imaging apparatus to instantly capture the particular image of the at least one face, if the comparing of the static characteristics detects fulfillment of the capturing requirements beyond a predefined threshold, wherein the processing module repeatedly compares, over time, the dynamic characteristics relating to changes in a position of the at least one face the facial sub objects thereof derived from the sequence of obtained images with corresponding dynamic characteristics relating to changes in a position of the at least one face and the facial sub objects thereof in the capturing requirements, and instruct the imaging apparatus to instantly capture an image of the at least one face if the comparing of the dynamic characteristics detects fulfillment of the capturing requirements beyond a predefined threshold, wherein the interface module is further arranged to allow the user to weight the static characteristics and the dynamic characteristics for a calculation of a total image grade, and wherein a particular percentage of a maximum total image grade is determined as a threshold indicator according to a default value.
