  • Publication number: 20240104034
    Abstract: A second memory has n banks accessible in parallel, and stores pixel data. An input DMA controller respectively transfers the pixel data stored in the second memory to n multiply-accumulate units by using n input channels. A sequence controller controls the input DMA controller so as to cause a first input channel to transfer the pixel data in a first pixel space of the input bank to a first multiply-accumulate unit and cause a second input channel to transfer the pixel data in a second pixel space of the same input bank to a second multiply-accumulate unit.

  • Publication number: 20230019982
    Abstract: An information processing apparatus including circuitry. The circuitry receives a question from one of a user terminal apparatus and an administrator terminal apparatus. The circuitry performs determination as to whether the question is transmitted from the user terminal apparatus or transmitted from the administrator terminal apparatus. The circuitry searches for one or more answers including a word included in the question. The circuitry calculates a weighting of each of the one or more answers. When the determination result indicates that the question is transmitted from the user terminal apparatus, the circuitry transmits an answer having a weighting satisfying a predetermined threshold value of the weighting to the user terminal apparatus. When the determination result indicates the question is transmitted from the administrator terminal apparatus, the circuitry generates screen information of a screen for editing at least one of one or more answers.

  • Patent number: 10298892
    Abstract: An image projection apparatus includes processing circuitry that receives, for each surface of a plurality of surfaces in a projection region, an adjustment value to increase or decrease an effective distance from an imaging device to a curved position of the surface. The processing circuitry further determines, for each surface, a curved shape of the surface in accordance with a change of distortion corresponding to the effective distance that was increased or decreased by the received adjustment value. The processing circuitry further calculates, for each surface, correction parameters to correct the distortion of projection images projected onto the surface, in accordance with the determined curved shape of the surface. The processing circuitry further divides an image into a plurality of divided images in accordance with positions and sizes of the each surface of the plurality of surfaces in the projection region.
