    摘要： A broadband imager, which is able to image both IR and visible light, is disclosed. In one embodiment, an IR sensitive region of an IR pixel underlies the R, G, B sensitive regions of R, G, and B visible pixels. Therefore, the IR pixel receives IR light through a same surface area of the photosensor through which the R, G, and B pixels receive visible light. However, the IR light generates electron-hole pairs deeper below the common surface area shared by the RGB and IR pixels, than visible light. The photosensor also has a charge accumulation region for accumulating charges generated in the IR sensitive region and an electrode above the charge accumulation region for providing a voltage to accumulate the charges generated in the IR pixel.

    摘要： An illumination system having a refractive optical element that compensates for dependence in irradiance of images of objects captured by a photosensor is provided. The refractive optical element may structure the light such that similar objects in the same spherical surface in the field of view of the camera have the same irradiance on the camera photosensor. The illumination system may have an image sensor, a light source, and a refractive optical element. The image sensor has a photosensor that captures images of objects in a field of view. The irradiance of images of objects having a given exitance that are captured by the photosensor may depend on angular displacement from an optical axis of the image sensor. The refractive optical structures light from the light source to illuminate the field of view to compensate for the dependence of irradiance on angular displacement from the optical axis.

    摘要： An imaging system includes first and second imaging arrays separated by a fixed distance, first and second drivers, and a modulated light source. The first imaging array includes a plurality of phase-responsive pixels distributed among a plurality of intensity-responsive pixels; the modulated light source is configured to emit modulated light in a field of view of the first imaging array. The first driver is configured to modulate the light output from the modulated light source and synchronously control charge collection from the phase-responsive pixels. The second driver is configured to recognize positional disparity between the intensity-responsive pixels of the first imaging array and corresponding intensity-responsive pixels of the second imaging array.

    摘要： A depth-sensing method for a time-of-flight depth camera includes irradiating a subject with pulsed light of spatially alternating bright and dark features, and receiving the pulsed light reflected back from the subject onto an array of pixels. At each pixel of the array, a signal is presented that depends on distance from the depth camera to the subject locus imaged onto that pixel. In this method, the subject is mapped based on the signal from pixels that image subject loci directly irradiated by the bright features, while omitting or weighting negatively the signal from pixels that image subject loci under the dark features.

    摘要： An image camera component and its method of operation are disclosed. The image camera component detects when ambient light within a field of view of the camera component interferes with operation of the camera component to correctly identify distances to objects within the field of view of the camera component. Upon detecting a problematic ambient light source, the image camera component may cause an alert to be generated so that a user can ameliorate the problematic ambient light source.
