Patent number: 11985396Abstract: Provided is a system that includes an event-driven vision sensor and an information processing device. The event-driven vision sensor includes a sensor array where a first sensor and a second sensor are arranged in a predetermined pattern. The first sensor generates a first event signal when detecting a change in an intensity of light incident through a first filter. The first filter selectively passes light in a first wavelength band. The second sensor generates a second event signal when detecting a change in an intensity of light incident through a second filter. The second filter selectively passes light in a second wavelength band that is different from the first wavelength band. The information processing device includes a first processing section and a second processing section. The first processing section executes a first process on the basis of the first event signal. The second processing section executes a second process different from the first process on the basis of the second event signal.Type: GrantFiled: June 26, 2019Date of Patent: May 14, 2024Assignee: Sony Interactive Entertainment Inc.Inventor: Tetsugo Inada

Publication number: 20230358892Abstract: Irradiation light from a sensor is separated into transmission light and reflected light through a one-way mirror to reach objects that are present in a plurality of directions. The one-way mirror concentrates the reflected light on the sensor. A position information acquisition device detects a local maximum point in a change in a degree of photons observed by the sensor, thereby acquiring path lengths of light to objects to generate position information on the basis of the position and the posture of the one-way mirror from the sensor.Type: ApplicationFiled: September 24, 2020Publication date: November 9, 2023Applicant: Sony Interactive Entertainment Inc.Inventors: Tetsugo INADA, Akihiro Takano, Yoshihiro Myokan

Publication number: 20230335024Abstract: Pulsed light emitted from a light emitter of a TOF sensor at an intensity is divided into light that is reflected by an object having transmissivity and reaches a light receiver at an intensity and light that passes through the object and reaches an object at an intensity. The latter is reflected by the object at an intensity, partly passing through the object to reach the light receiver at an intensity. A local maximum point is detected in a change in a degree of photons observed by the light receiver, to acquire both distances to the object and the object.Type: ApplicationFiled: September 23, 2020Publication date: October 19, 2023Applicant: Sony Interactive Entertainment Inc.Inventors: Akihiro Takano, Yoshihiro Myokan, Tetsugo INADA

Publication number: 20230316558Abstract: A distance information generation apparatus obtains a measurement depth image that expresses a measurement result for a distance to an object and a color image captured at a corresponding field of view. The measurement depth image is upsampled by a predetermined technique to generate a candidate depth image. On the basis of a result of analyzing the color image, a reflection characteristic for the object, and information regarding a relative motion between an image capturing apparatus and the object, a reliability image, in which a reliability for a distance value expressed by the candidate depth image is set for each pixel, is generated. A distance value having a high reliability is read out for each pixel from the candidate depth image, whereby an output depth image is generated.Type: ApplicationFiled: September 24, 2020Publication date: October 5, 2023Applicant: Sony Interactive Entertainment Inc.Inventors: Akihiro Takano, Yoshihiro Myokan, Tetsugo Inada

Publication number: 20230306676Abstract: An image generation device divides a distorted-image plane into pixel blocks in order to generate a distorted image in consideration of the distortion and chromatic aberration of an eyepiece. In the plane of a source image, the image generation device determines individual RGB sample positions included in the pixel blocks, sets a bounding rectangle containing the individual RGB sample positions, and determines, for example, computation target pixels corresponding to the bounding rectangle. The image generation device calculates the pixel values of, for example, the computation target pixels, interpolates and samples the calculated pixel values, and regards the results of interpolation and sampling as the pixel values of the distorted image.Type: ApplicationFiled: September 29, 2020Publication date: September 28, 2023Applicant: Sony Interactive Entertainment Inc.Inventors: Tetsugo Inada, Akio Ohba, Takayuki Shinohara, Norihide Kaneko

Publication number: 20230289929Abstract: An image generating apparatus directly draws, by using scene data, a distortion image generated by giving common distortion to primary colors of R, G, and B, and transmits the distortion image to a head mounted display in an order of drawn pixel sequences. The head mounted display acquires color information from positions different for each of R, G, and B and dependent on chromatic aberration of an ocular lens in partial data of the distortion image stored in a line buffer. In this manner, the image generating apparatus generates partial data, each having different distortion, for R, G, and B, respectively, and immediately outputs the generated partial data to a display panel.Type: ApplicationFiled: September 8, 2020Publication date: September 14, 2023Applicant: Sony Interactive Entertainment Inc.Inventors: Tetsugo Inada, Akio Ohba
