  • Publication number: 20220321796
    Abstract: An image processing system includes a generating unit and a storing unit. The generating unit determines a subject included in a wide-angle image and generate a partial image including the subject from the wide-angle image. The storing unit stores the partial image in association with the wide-angle image from which the partial image is extracted.

  • Publication number: 20210250500
    Abstract: An information processing method is performed by an information processing apparatus including a communication interface and an imaging device. The method includes acquiring a wide-angle image from an external imaging device via the communication interface; invoking an imaging function implemented by the imaging device; acquiring a captured image imaged by the imaging device; and associating the acquired wide-angle image with the acquired captured image.

  • Patent number: 9516287
    Abstract: The present invention is concerning an imaging device comprising: a photoelectric conversion unit that generates imaging signals corresponding to imaging light received from an imaging object; a summation unit that performs summation of the imaging signals generated by the photoelectric conversion unit; a summation controller that controls the summation unit such that the summation unit performs, per line, an operation of summation of imaging signals acquired from the photoelectric conversion unit during the time period of one line for the number of plural times in periods that are twice as much as that of the spatial frequency of the imaging object or more; and a signal generator that generates and outputs an imaging signal of each line from plural sum outputs generated per line.

  • Patent number: 9118873
    Abstract: An imaging device includes photoelectric conversion elements arranged unidirectionally for each color of light to be received, and performing photoelectric conversion of reflected light from an approximately same position of an object for the each color sequentially pixel by pixel; and a black correction unit that corrects a black level of the object with respect to a pixel group including some photoelectric conversion elements in a way that an output result of the photoelectric conversion of reflected light by a photoelectric conversion element for a pixel, independent of the reflected light, is subtracted from another output result of photoelectric conversion of reflected light by the photoelectric conversion element for the same pixel.
