  • Patent number: 11946780
    Abstract: A scale includes a diffraction grating configured to condense diffracted light in a periodic direction of the diffraction grating in order to detect a reference position. A light receiving element array is configured to receive light from the diffraction grating. The light receiving element array includes first to fourth light receiving elements configured to output signals having phases different from each other. The first light receiving element and the second light receiving element are adjacent to each other and are arranged between the third light receiving element and the fourth light receiving element. The processing unit generates a signal representing the reference position based on a differential signal between a signal from the first light receiving element and a signal from the third light receiving element and a differential signal between a signal from the second light receiving element and a signal from the fourth light receiving element.

  • Patent number: 11948282
    Abstract: An image processing apparatus generates a normal image, when lighting correction of an image is performed using three-dimensional shape data. Three-dimensional shape data of a predetermined object is adjusted with a subject in position, based on a feature pattern detected in image data, and lighting processing for correcting a pixel value of the image data is performed based on the adjusted three-dimensional shape data, distance information of the subject, and a position of a virtual light source. When the three-dimensional shape data is adjusted with the image data in position, a region having a large irregularity in the three-dimensional shape data is preferentially adjusted in position.
