A device for capturing a biometric print of a user, the user compartment including a frontal opening designed for the passage of part of a hand into said user compartment and a lateral opening allowing the passage of the thumb of the user's hand, the lateral opening extending as far as the frontal opening to form a continuous open space, the lateral opening being delimited in a direction of insertion of the user's hand into the user compartment by a user hand positioning stop.

Ergonomic biometric print capture device

A method for determining a point spread function of an imaging system. The method includes: for each position in a plurality of positions of a target in an optical field of the imaging system: acquiring an image of the target, referred to as the real image; obtaining a synthetic image of the target representing a digital model of the target adjusted to a zone of the real image corresponding to the target so that the model coincides with the zone; estimating the point spread function using the real image and the synthetic image; and calculating an optical transfer function by applying a Fourier transform to the point spread function; calculating an average optical transfer function from the optical transfer functions calculated for each position in the plurality of positions; and obtaining an average point spread function by applying an inverse Fourier transform to the average optical transfer function.

Method for determining a point spread function of an imaging system

The invention relates to a method, for determining a distance between an object with respect to an imaging system, improving the reconstruction of images of objects imaged by an imaging system and improving the resolution of the images obtained.
