  • Patent number: 11922307
    Abstract: With respect to an inference method performed by at least one processor, the method includes inputting, by the at least one processor, into a learned model, non-processed object image data of a second object and data related to a second process for the second object, and inferring, by the at least one processor using the learned model, processed object image data of the second object on which the second process has been performed. The learned model has been trained so that an output obtained in response to non-processed object image data of a first object and data related to a first process for the first object being input approaches processed object image data of the first object on which the first process has been performed.

  • Patent number: 11543095
    Abstract: A lens holder which supports a projection lens is screwed and fixed to a bracket which supports a spatial light modulator. A positioning pin configured to position the lens holder in a left-right direction with respect to the bracket is inserted into a long hole which is formed in the bracket and extends in a lamp front-rear direction. The screwing and fixing is performed in a state where the positioning pin is inserted into the long hole and is appropriately moved in the lamp front-rear direction, so that the lens holder is restricted from being displaced in a left-right direction with respect to the bracket, and it is possible to finely adjust a positional relationship between the projection lens and the spatial light modulator in the lamp front-rear direction.

  • Patent number: 10895357
    Abstract: A vehicle lamp forms an additional high-beam light distribution pattern with light emitted though a projection lens from a plurality of light emitting elements. The plurality of light emitting elements are disposed to be aligned in a transverse direction below a rear focal point of the projection lens and can be lit individually. The vehicle lamp forms an additional light distribution pattern by lighting the plurality of light emitting elements at the same time to form a high-beam light distribution pattern. In addition, the vehicle lamp forms another additional light distribution pattern where a part of the additional light distribution pattern is omitted by selectively lighting a part of the plurality of light emitting elements so as to form an intermediate light distribution pattern.
