The present invention relates biometric authentication using an optical biometric arrangement comprising an image sensor comprising a photodetector pixel array configured to capture an image of an object, the image sensor being arranged under a controllable light source comprising light source units, the method comprising: providing a light pattern comprising portions of different light intensity for illuminating the object; acquiring an image of the object, the image comprising image portions corresponding to the portions of different light intensity of the light pattern illuminating the object, at least one image portion being captured by pixels in he photodetector pixel array arranged directly under a light source unit being active during image acquisition, and at least one image portion being captured by pixels in the photodetector pixel array arranged under an at least partly in-active illumination area of the controllable light source during image acquisition, performing biometric authentication at least partly based on metrics extracted from the image portions.

To provide an electronic device capable of suppressing a decrease in resolution when the distance between an object to be imaged and an imaging unit is decreased. This electronic device includes a plurality of pixels, each of at least two pixels of the plurality of pixels including: a first lens that collects incident light; a first light shielding film portion having a first hole through which a part of the incident light that has been collected passes; and a photoelectric conversion unit configured to photoelectrically convert the incident light having passed through the first hole. The shape of the first hole with respect to the first light shielding film portion is different between a first pixel among the at least two pixels and a second pixel different from the first pixel among the at least two pixels.

An interval between a pinhole and a pinhole is set to a first interval at which a degree of superimposition of subject images captured through the corresponding pinholes falls within a predetermined range when an image of a subject located at a distance less than a predetermined distance from the multi-pinhole camera is captured. An interval between the pinhole and a pinhole is set to a second interval narrower than the first interval at which a degree of superimposition of subject images captured through the corresponding pinholes falls within a predetermined range when an image of the subject located at a distance equal to or more than the predetermined distance from the multi-pinhole camera is captured.

Scanners, methods, and computer storage media having computer-executable instructions embodied thereon that process variable sized objects with high package pitch on a moving conveyor belt are provided. The scanners include a substrate and a plurality of sensors attached to the substrate. The plurality of sensors forms an array of sensors having at least two or more rows of off-axis sensors. The sensors may include a one or more area array sensors. The arrays of sensors captures moving objects row by row and are optimized reduce object spacing on the conveyor belt. Additionally, the scanner having the array of sensor may process different objects having different heights at the same time. Accordingly, object throughput on the conveyor belt is increased by reducing minimum object gap (e.g., processing of “no gap” or non-singulated objects).
