    摘要： 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.

    摘要： 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.

    摘要： An image capture accelerator performs accelerated processing of image data. In one embodiment, the image capture accelerator includes accelerator circuitry including a pre- processing engine and a compression engine. The pre-processing engine is configured to perform accelerated processing on received image data, and the compression engine is configured to compress processed image data received from the pre-processing engine. In one embodiment, the image capture accelerator further includes a demultiplexer configured to receive image data captured by an image sensor array implemented within, for example, an image sensor chip. The demultiplexer may output the received image data to an image signal processor when the image data is captured by the image sensor array in a standard capture mode, and may output the received image data to the accelerator circuitry when the image data is captured by the image sensor array in an accelerated capture mode.

    摘要： To compensate for a focal plane shifting away from an image plane due to a temperature change, an integrated image sensor and lens assembly includes an optical component and an optics compensator including passively actuating elements. The passively actuating elements couple the optical component to the inner surface of the lens mount. The passively actuating elements and the optics component are configured such that the focal plane is maintained to coincide with or substantially coincide with the image plane. The passively actuating elements and the optics component adjust the distance an incident ray travels in the optics compensator when the temperature changes to thereby maintaining the focal plane to coincide with or substantially coincide with the image plane.
