    Abstract: Provided is an optical displacement meter capable of enlarging an output signal region with respect to a region in which a light-receiving amount needs to be measured, a method for adjusting an optical displacement meter, and an optical displacement measuring method. The optical displacement meter includes a light-receiving element in which a maximum value of an output signal is set with respect to a boundary value, which is a maximum value of a region in which the light-receiving amount needs to be measured. The entire region of the output signal of the light-receiving element can be assigned to the valid region, in which the light-receiving amount needs to be measured with an optical displacement meter, and the optical displacement meter can have an enlarged output signal region with respect to the region in which the light-receiving amount needs to be measured.

  • Patent number: 10419689
    Abstract: To enable better encoding of the currently starting to appear high dynamic range images for use in full high dynamic range technical systems (containing an HDR display, and e.g. in an HDR grading application), we invented a method of constructing a code allocation function for allocating pixel colors having pixel luminances to codes encoding such pixel luminances, in which the step of determining the code allocation function to be applied to at least one color coordinate of the pixel to obtain a code value, comprises constructing that function out of at least two partial functions, and similar methods at a receiving side, and apparatuses, and signals for communicating between the two sites. This method allows—in line with applicant's technical approach that HDR images should actually be communicated as a spectrum of differently regraded different dynamic range images of the same scene, e.g.

  • Patent number: 10366125
    Abstract: An object display system for a relationship graph includes an object information reception unit that receives object information from a terminal device. A node conversion unit converts the object information into a corresponding node and sets the node as a reference point node. A relationship graph extraction unit extracts a relationship graph containing the reference point node from a relationship graph database. A node relationship evaluation unit evaluates the relationship of each node to a reference point node by scores of two types of evaluation indexes. An object arrangement unit converts each node into a corresponding object and arranges each object converted from each node while making scores of two types of evaluation indexes by the node relationship evaluation unit that correspond to a two-dimensional coordinate. An object output unit outputs each object to the terminal device.
