  • Publication number: 20230097715
    Abstract: In a camera system, a captured image of a rear of a vehicle is acquired, an optical image having a high-resolution region and a low-resolution region is formed on an imaging unit, a first image is generated by cutting out a first region from an image region corresponding to the high-resolution region in an image read from the imaging unit, a second image is generated by cutting out a second region from an image region different from the first region, the first image and the second image are generated such that at least a portion of a lower end of the second region is positioned below a lower end of the first region, and at least a portion of an upper end of the second region is positioned below an upper end of the first region, and at least one of the first image and the second image is output for display.

  • Publication number: 20230096414
    Abstract: A method of installing a camera unit including an imaging device and an optical system that forms an optical image on a light receiving surface of the imaging device, wherein the light receiving surface includes a first area and a second area on a peripheral side of the first area, wherein an increase in an image height with respect to a unit half angle of view in the first area is larger than an increase in an image height with respect to a unit half angle of view in the second area, wherein the optical system and the imaging device are disposed such that the gravity center of the first area deviates in a first direction from the center of the light receiving surface, and wherein the method includes installing the camera unit such that the first direction is directed to an area other than a predetermined targeted area.

  • Publication number: 20230100249
    Abstract: An information processing device includes one or more memories and one or more processors. The one or more processors and the one or more memories are configured to receive control information and data that contains three-dimensional position information generated by a three-dimensional range sensor and convert, based on the received control information, the three-dimensional position information contained in the data received from the three-dimensional range sensor into two-dimensional image data containing information on a distance from a predetermined viewpoint.

  • Patent number: 10475402
    Abstract: A liquid crystal driving apparatus includes a driver configured to form a gradation in the pixel based on each gradation value in the plurality of sub-frame image data by sequentially controlling an application of a first voltage and an application of a second voltage lower than the first voltage for the plurality of pixels in each of a plurality of sub-field periods contained in one frame period. Where an input gradation value is defined as the gradation value of the input frame image data, the image data generator generates a first sub-frame image data having a first gradation value higher than the input gradation value and a second sub-frame image data having a second gradation value lower than the input gradation value as at least the plurality of sub-frame image data.
