  • Patent number: 10237520
    Abstract: The present invention discloses an imaging system, including an optical lens, where a spectroscopical module that can split a light wave transmitted from the optical lens into three light waves in different wavelength ranges is disposed on an imaging side of the optical lens; and the imaging system further includes three photosensitive chips configured to receive corresponding light waves, where the three photosensitive chips are correspondingly distributed at three light waves emitted by the spectroscopical module, and the spectroscopical module is a prism. In the present invention, a spectroscopical module is used to separate light whose wavelengths are different, and therefore light waves that are output from the spectroscopical module are three light waves in different wavelength ranges. These light waves in the different wavelength ranges are separately received by three different photosensitive chips.

Based on lens design values, chromatic aberration of magnification in each area is calculated as the amount of lens chromatic aberration of magnification. By using the amount of area chromatic aberration of magnification and the amount of lens chromatic aberration of magnification in adjacent areas next to an indefinite area matching predetermined conditions, the amount of lens chromatic aberration of magnification relating to the indefinite area is corrected to determine the amount of area chromatic aberration of magnification relating to the indefinite area.

  • Patent number: 8520138
    Abstract: A digital panoramic camera generally comprises a lens dependently secured to a body. The body comprises a power side, control side and rear compartment wherein the internal components of the digital panoramic camera are distributed such that their weight is uniformly placed about the axis of rotation for the camera. Because the axis of rotation for the camera passes through the nodal point of the lens, a slotted aperture is provided in the body in order that the camera may nonetheless have a nearly 180° vertical field of view. A novel lens cover, having a slotted aperture therein, is provided for reduction or elimination of flare, thereby improving image quality. Provisions are also made for elimination of fringe effects and blooming as well as for improved user interface with the camera. A novel interface permits operation of the camera as either a stand-alone or peripheral device.

  • Patent number: 8514321
    Abstract: A wavelength detecting apparatus capable of detecting the main wavelength of the light coming into an image capture apparatus and a focus detecting apparatus using the same are disclosed. The wavelength detecting apparatus may include a spectral unit which separates the incoming light according to the respective wavelengths, and may focus the separated light onto a sensor. The main wavelength can be determined based on the wavelength distribution sensed by the sensor. The determined wavelength can be used to further determine amount of adjustment to be made to the defocus amount to compensate for the chromatic aberration associated with the wavelength of the light illuminating the source.

    Abstract: Snapshot spectral imagers comprise an imaging lens, a dispersed image sensor and a restricted isometry property (RIP) diffuser inserted in the optical path between the source image and the image sensor. The imagers are used to obtain a plurality of spectral images of the source object in different spectral bands in a single shot. In some embodiments, the RIP diffuser is one dimensional. An optional disperser may be added in the optical path, to provide further dispersion at the image sensor. In some embodiments, all imager components except the RIP diffuser may be part of a digital camera, with the RIP diffuser added externally. In some embodiments, the RIP diffuser may be included internally in a digital camera.
