  • Patent number: 10309528
    Abstract: The present invention is configured such that: in a stopped state of an electric oil pump (M/O/P), control of the electric oil pump (M/O/P) is started such that, when a driver has the intention of demanding drive force, a discharge pressure takes on a target hydraulic pressure (PTh) determined in accordance with the demanded drive force from the driver; and a pressure regulation target value of a line pressure regulation valve (101) is set to a value that is higher than or equal to the target hydraulic pressure (PTh). Thus, it is possible to provide a vehicular hydraulic control device capable of suppressing hunting in line pressure (PL) when the line pressure (PL) is regulated so as to take on the target hydraulic pressure (PTh).

  • Patent number: 10063788
    Abstract: An image processing apparatus includes an image acquirement section, a correction section, and an image production section. The image acquirement section acquires an image signal representing an image, the image signal is generated by light receiving elements that receive lights from a specific space preliminarily defined in a vicinity of a vehicle via a near infrared passing filter mainly transmitting near infrared lights and a visible light passing filter transmitting visible lights and near infrared lights, respectively. The image includes multiple areas and indicates the specific space projected onto a plane. The correction section corrects each area of the image by amplifying intensity of near infrared lights with an increasing amplification factor when a difference between the intensity of near infrared lights and intensity of visible lights and near infrared lights becomes smaller. The image production section produces a new image based on the corrected areas of the image.

  • Patent number: 9497395
    Abstract: A night-vision device is provided with a projection unit, an image pickup unit, a luminance ratio determining unit, and a projection control unit. The luminance ratio determining unit determines whether a determination luminance ratio in a set region is within a predetermined luminance range as a luminance ratio at which a subject to be detected forms an emphasized image, said set region having been set at least in a part of an image obtained by means of the image pickup unit. In the cases where the determination luminance ratio is out of the predetermined luminance range, the projection control unit controls the intensity of near-infrared light emitted from the projection unit such that the determination luminance ratio is within the predetermined luminance range.

    Abstract: The present invention relates to an information processing device, an information processing method, and a program capable of easily adding an annotation to content. A feature amount extracting unit 21 extracts an image feature amount of each frame of an image of learning content and extracts word frequency information regarding frequency of appearance of each word in a description text describing a content of the image of the learning content (for example, a text of a caption) as a text feature amount of the description text. A model learning unit 22 learns an annotation model, which is a multi-stream HMM, by using an annotation sequence for annotation, which is a multi-stream including the image feature amount of each frame and the text feature amount. The present invention may be applied when adding the annotation to the content such as a television broadcast program, for example.
