    摘要: The present technology is directed to determining an accuracy of an infrared (IR) camera, and more particularly, validating a distortion accuracy of an IR camera. The present technology can receive one or more images of a calibration harp captured by the IR camera, wherein the one or more images include a plurality of lines corresponding to a plurality of strings of the calibration harp. The present technology can further determine a degree of distortion of the plurality of lines based on a distortion error coefficient, wherein the distortion error coefficient is computed based on edge points of the plurality of lines on the one or more images.

    摘要: An image sensing assembly includes an enclosure that defines a first viewport aperture in a front wall of the enclosure. The image sensing assembly includes a first image sensor attached within the enclosure, the first image sensor aligned with the first viewport aperture in the front wall of the enclosure to capture image data representative of a scene viewed through the first viewport aperture. The image sensing assembly includes a bracket attached to the enclosure at a first portion of the bracket and attached to a first mounting plate at a second portion of the bracket. The image sensing assembly includes a vibration dampening mount located between the bracket and the first mounting plate to at least partially isolate the enclosure from vibration of the first mounting plate.

    摘要: A focus assist circuit for a viewfinder, including a video amplifier configured to amplify a video signal, a video gain controller configured to adjust gain of the video amplifier to provide peaking headroom, and a peaking processor configured to adjust the amplified video signal. The focus assist circuitry may facilitate focusing a camera lens by proving peaking headroom for a peaking signal that is combined with an amplified signal. The peaking headroom limits the gain applied to a video signal in order to reduce distortions in the peaks. A user interface may include input controls configured to limit the gain of the of a video amplifier.

    摘要: To satisfactorily detect an edge detection signal of a high frequency band from a captured image signal at all times.A filtering unit extracts an edge detection signal of a high frequency band from an image signal obtained from imaging, and a band control unit controls the high frequency band on the basis of lens information. For example, the filtering unit includes a first high-pass filter with a first cutoff frequency, a second high-pass filter with a second cutoff frequency that is lower than the first cutoff frequency, and an a blending unit that performs a blending on output of the first high-pass filter and output of the second high-pass filter. Even if the frequency of the edge detection signal included in the captured image signal varies due to a change in a zoom position, a lens model number, an F value or the like, the edge detection signal can be satisfactorily detected at all times.
