  • Publication number: 20220147731
    Abstract: To provide an imaging device capable of reducing discomfort caused by visible light. A light source can emit the visible light and invisible light as irradiation light. An imaging unit captures an image of an irradiation region irradiated with the irradiation light to acquire an image. A processor causes the imaging unit to acquire a detection image in a first irradiation mode in which the invisible light is emitted from the light source, and determines whether a biometric object is presented in the irradiation region based on the detection image. When the biometric object is presented, the processor causes the imaging unit to acquire the biometric image obtained by copying the biometric object as the image in a second irradiation mode in which the visible light and the invisible light are emitted from the light source.

  • Publication number: 20200167003
    Abstract: A head-mounted display (HMD) 1, which is operated by a gesture operation performed by a user 3, is provided with a distance image acquisition unit 106 that detects a gesture operation, a position information acquisition unit 103 that acquires position information of the HMD 1, and a communication unit 2 that performs communication with another HMD 1?. A control unit 205 sets and displays an operating space 600 where a gesture operation performed by the user 3 is valid, exchanges position information and operating space information of the host HMD 1 and the other HMD 1 therebetween by the communication unit 2, and adjusts the operating space of the host HMD so that the operating space 600 and an operating space 600? of the other HMD 1 do not overlap each other.

  • Publication number: 20170090887
    Abstract: There has been a demand for a technology capable of more efficiently arranging each variable used within a program because the storage capacity of a memory area is limited. A programming language processing program oriented to a microcomputer having a plurality of memory areas is provided. Based on a source program or an object code generated from the source program, information for determining which memory area of the memory areas the variable used within the source program should be arranged in is outputted as arrangement determination information. As to each aggregate variable used within the source program, the arrangement determination information includes information for each element of the corresponding aggregate variable.

  • Patent number: 6263428
    Abstract: A branch predictor for predicting an instruction to be executed next to a conditional branch instruction in a program to read the predicted instruction beforehand. The branch predictor includes a hint acquisition section for acquiring a hint when a specified instruction controlling acquisition of the hint is executed wherein said hint indicates whether a branch is to be taken by execution of a conditional branch instruction with which termination of a loop is judged. The branch predictor further includes a hint store section for storing the hint acquired by the hint acquisition section, and an instruction read section for reading an instruction predicted as executed next to a conditional branch instruction in accordance with the hint stored in the hint store section. According to the invention it is possible to accurately predict a branch at the time of loop termination of the loop termination judging conditional branch instruction.
