  • Patent number: 10918465
    Abstract: The invention provides a three-dimensional object scanning device using structured lights and method using the same. A combination of specific monochrome light sources is used to construct the content of the structured lights to form a predetermined image, which is projected to the three-dimensional object such as an intraoral object. The combination of blue and green lights effectively eliminates reflective interference of the red or white environment within the intraoral space. Default patterns of the predetermined image are distinguished from one another by using well designed arrangement of color blocks so that specific coding information of location may be embedded and exploited.

  • Patent number: 10853909
    Abstract: The present invention relates to an image processing apparatus which determines an order for calculating output image pixels that maximally reuses data in a local memory for computing all relevant output image pixels. Thus, the same set of data is re-used until it is no longer necessary. Output image pixel locations are browsed to determine pixel values in an order imposed by available input data, rather than in an order imposed by pixel positions in the output image. Consequently, the amount of storage required for local memory as well as the number of input image read requests and data read from memory containing the input image is minimized.

Each of the multiple hyperspectral prototype components comprises multiple component values associated with respective wavelengths and each of the multiple component values is based on multiple points of training image data associated with the wavelength of that component value. Since the component values are based on multiple points of the training image, relationships between points in the training image, such as texture, can be used to reconstruct the hyperspectral image data, which leads to a more robust and more accurate reconstruction.

  • Patent number: 10387743
    Abstract: A method for image reconstruction includes defining a dictionary including a set of atoms selected such that patches of natural images can be represented as linear combinations of the atoms. A binary input image, including a single bit of input image data per input pixel, is captured using an image sensor. A maximum-likelihood (ML) estimator is applied, subject to a sparse synthesis prior derived from the dictionary, to the input image data so as to reconstruct an output image comprising multiple bits per output pixel of output image data.

  • Patent number: 10339631
    Abstract: A hybrid optical sensor array includes a first and second set of pixels having differing spectral sensitivities. A first set of data for a scene is captured by the first set of pixels at a first resolution, and a second set of data for the scene is captured by a second set of pixels at a second resolution. The first set of data is demosaiced based on at least the second set of data. A third set of data for the scene is output at a third resolution, greater than the first resolution. This allows high resolution matching images to be produced without perspective or timing discrepancies inherent in multi-camera machine vision systems.

  • Patent number: 10290079
    Abstract: An image processing method and apparatus, and an electronic device are provided. The image sensor is controlled to output the compositing image. The merged image and the color-block image can be output respectively under different scenes requiring different imaging effect. Then the preset target region is identified in the merged image. Finally, the processed merged image (i.e. the merged true-color image) corresponding to the preset target region is composited with the processed color-block image (i.e. the simulation true-color image). Therefore, the signal-to-noise ratio, the resolution and distinguishability are improved. The placed location in the simulation true-color image can be manually adjusted, thereby enhancing user experience.

    Abstract: An imaging device comprises a hybrid optical sensor array including a first and second set of pixels that comprise different numbers of pixels. The first set of pixels is sensitive to infrared light, while the second set of pixels comprises three subsets of pixels sensitive to RGB light. A first set of data for a scene is captured by the first set of pixels and a second set of data for the scene is captured by a second set of pixels. The first and second sets of data are jointly demosaiced, such that the higher resolution data set is utilized to increase the resolution of a lower resolution data set. This allows for high-resolution infrared and RGB images to be produced for a scene without perspective or timing discrepancies inherent in multi-camera machine vision systems.
