Abstract: A camera system includes two or more sensor arrays and an optical path. The sensor arrays are on the same sensor chip. Each sensor array includes the same field of view (FOV) as each other sensor array. The optical path includes a main lens and a metalens that are shared by each sensor array, and a microlens associated with each sensor array. The metalens splits incident light into different spectrums of light and directs each respective spectrum to a corresponding sensor array. The different spectrums of light include at least two of visible light, near infrared light, shortwave infrared and longwave infrared, and at least one sensor array includes single-photon avalanche diodes. The image processor that provides image processing, object recognition and object tracking and/or image fusion functionality may be on the same sensor chip as the sensor arrays.

Abstract: A system and a method are disclosed to approximately calculate a mathematical function using a digital processing device. An acceleration function is performed on at least one operand for a mathematical function. The acceleration function includes a predetermined sequence of addition operations that approximate the mathematical function in which the mathematical function may be a base-2 logarithm, a power of 2, a multiplication, an inverse square root, an inverse, a division, a square root, and an arctangent. The predetermined sequence of addition operations may include a first predetermined number of additions of integer-formatted operands and a second predetermined number of additions of floating-point-formatted operands in which the additions of integer-formatted operands and additions of floating-point-formatted operands can occur in any order.

Abstract: A pixel for an image sensor includes a microbolometer sensor portion, a visible image sensor portion and an output path. The microbolometer sensor portion outputs a signal corresponding to an infrared (IR) image sensed by the microbolometer sensor portion. The visible image sensor portion outputs a signal corresponding to a visible image sensed by the visible image sensor portion. The output path is shared by the microbolometer and the visible image sensor portions, and is controlled to selectively output the signal corresponding to the IR image or the signal corresponding to the visible image. The output path may be further shared with a visible image sensor portion of an additional pixel, in which case the output path may be controlled to selectively to also output the signal corresponding to a visible image of the additional pixel.

Abstract: An imaging unit includes a light source and a pixel array. The light source projects a line of light that is scanned in a first direction across a field of view of the light source. The line of light oriented in a second direction that is substantially perpendicular to the first direction. The pixel array is arranged in at least one row of pixels that extends in a direction that is substantially parallel to the second direction. At least one pixel in a row is capable of generating two-dimensional color information of an object in the field of view based on a first light reflected from the object and is capable of generating three-dimensional (3D) depth information of the object based on the line of light reflecting from the object. The 3D-depth information includes time-of-flight information.

Abstract: A computing device includes a system that authenticates a user of the computing device. A first sensor obtains a first representation of a physical characteristic of the user that is compared to a registered representation of the physical characteristic of the user. A first level of access to the computing device is enabled based on the first representation of the physical characteristic matching the second representation of the physical characteristic. A second sensor obtains a first representation of a liveness characteristic of the user that indicates that the user is alive. The first representation of the liveness characteristic is compared to a registered representation of the liveness characteristic of the user. A second level of access to the computing device is enabled based on the first representation of the liveness characteristic of the user matching the second representation of the liveness characteristic of the user.
