Abstract: An integrated image sensor and lens assembly may include a lens barrel, a collet, and a lens mount. The lens barrel may be coupled to the collet which is coupled to the lens mount. The lens barrel and the collet may each include a fastening structure reciprocal to each other. Alternatively, the collet and the lens mount may each include a fastening structure reciprocal to each other. The optical distance between the set of lenses and the image sensor may be tuned such that the focal plane of the lenses coincides with the image plane. The fastening structures allow the lens barrel to be adjusted relative to the lens mount in order to shift the focal plane in a direction along the optical axis to compensate for focal shifts occurring during assembly/cure and/or temperature cycling.

Abstract: Systems and methods are disclosed that capture and compress frames of pixel data. In an implementation, an image sensor chip converts light into pixel data and generates transform data by applying a transform to a portion of the pixel data associated with a pixel category from a plurality of pixel categories and generates compressed pixel data at a variable compression rate by compressing the transform data. The variable compression rate is within an available bandwidth of an output bus that outputs the compressed pixel data.

Abstract: An opto-acoustic transducer may include a light source, a substrate, a top layer, an interstitial layer, a lens, and a detector array. The light source may generate light beams. The substrate may reflect the light beams generated by the light source. The top layer may modulate responsive to an acoustical wave impingent thereupon and may reflect the light beams generated by the light source. The interstitial layer may be between the substrate and the top layer and may include a cavity which acts as an optical collector. The lens may propagate the light beams reflected by the substrate and the light beams reflected by the top layer. The detector array may reconstruct the acoustical wave impingent on the top layer based on the light beams propagated by the lens.

Abstract: A camera system includes an image sensor assembly and a tunable optical element. The tunable optical element is a doublet prism including one polymer dispersed liquid crystal layer. The doublet prism is tunable by applying an electric field to the optical element via a control element. The control element applies a voltage differential to the optical element inducing an electric field which changes the polarization of the PDLC within the optical element. The refractive index of the doublet prism is dependent on the polarization of the liquid crystals within the optical element. Applying the electric field to the tunable element changes the optical properties of the doublet prism.

Abstract: A camera system includes an image sensor assembly and a tunable optical element. The tunable optical element is a holographic polymer dispersed liquid crystal diffraction grating of alternating PDLC layers. The diffraction grating is tunable by applying an electric field to the optical element via a control element. The control element applies a voltage differential to the optical element inducing an electric field which changes the polarization of the PDLC within the optical element. The refractive index of the holographic grating is dependent on the polarization of the liquid crystals within the optical element. Applying the electric field to the tunable element changes the optical properties of the grating.

Abstract: An image processor adjusts luminance values of pixels in a captured image to compensate for effects on focal quality due to thermal expansion or contraction. Responsivity values for different colors are characterized and a table is generated mapping temperature values to weights for each pixel color based on the relationship between temperature and focal length and the relationship between focal length and focal quality in each different color. Luminance values for one color may be compensated based on the measured luminance values for other colors, the relative responsivity values, and the weights.

Abstract: An audio system encodes and decodes audio captured by a microphone array system in the presence of wind noise. The encoder encodes the audio signal in a way that includes beamformed audio signal and a “hidden” representation of a non-beamformed audio signal. The hidden signal is produced by modulating the low frequency signal to a high frequency above the audible range. A decoder can then either output the beamformed audio signal or can use the hidden signal to generate a reduced wind noise audio signal that includes the non-beamformed audio in the low frequency range.

Abstract: Disclosed is an electronically controlled camera iris device. The camera iris device may include a transparent conductor layer supplying an input voltage controlling the diameter of the aperture, a transparent resistance layer providing different voltages in different regions varying based on the distance from a center point, and a diaphragm layer that can be independently controlled in different regions to block or transmit light incident on the diaphragm layer when corresponding control voltages are applied on the diaphragm layer. The camera iris device can be configured to have a desired diameter by controlling a first region of the diaphragm layer to transmit the light and a second region of the diaphragm layer outside of the first region to block the light. The diaphragm layer may include a Bragg grating layer or an Electrochromic layer.

Abstract: Multiple cameras are arranged in an array at a pitch, roll, and yaw that allow the cameras to have adjacent fields of view such that each camera is pointed inward relative to the array. The read window of an image sensor of each camera in a multi-camera array can be adjusted to minimize the overlap between adjacent fields of view, to maximize the correlation within the overlapping portions of the fields of view, and to correct for manufacturing and assembly tolerances. Images from cameras in a multi-camera array with adjacent fields of view can be manipulated using low-power warping and cropping techniques, and can be taped together to form a final image.
