  • Patent number: 10551535
    Abstract: An image pickup apparatus that is capable of preventing degradation of quality of an image obtained. An insertion-extraction unit inserts and extracts a filter of which transmittance for infrared light is higher than the transmittance for visible light. A computation unit computes an object distance between the image pickup apparatus and an object. An evaluation unit evaluates an image quality based on at least a sharpness in an image including a picked up object image. A control unit controls the insertion-extraction unit so as to insert or extract the filter based on at least one of the image quality and the object distance.

  • Patent number: 10534116
    Abstract: The present disclosure generally relates to hyperspectral spectroscopy, and in particular, to systems, methods and devices enabling a single-sensor hyperspectral imaging device. Hyperspectral (also known as “multispectral”) spectroscopy is an imaging technique that integrates multiples images of an object resolved at different narrow spectral bands (i.e., narrow ranges of wavelengths) into a single data structure, referred to as a three-dimensional hyperspectral data cube. Data provided by hyperspectral spectroscopy allow for the identification of individual components of a complex composition through the recognition of spectral signatures of individual components within the three-dimensional hyperspectral data cube.

  • Patent number: 10380717
    Abstract: An image processing method is provided. The image sensor outputs a merged image and a color-block image in a same scene. A preset target region is identified in the merged image. A part of the color-block image corresponding to a part of the merged image beyond the preset target region is converted into a first image using a first interpolation algorithm, and a part of the merged image within the preset target region is converted into a second image using a second interpolation algorithm. The first image and the second image are merged into a simulation image. An image processing apparatus and an electronic device are provided. With the image processing method and apparatus, and the electronic device the situation that the image sensor needs to take a long work to output a high quality image can be avoided, thus reducing the work time and improving the work efficiency.
