  • Publication number: 20240142628
    Abstract: An object detection device includes: a light emitter that emits light; a sensor that generates a first pixel signal by exposure to reflected light according to a combination of emission by the light emitter and first exposure and a second pixel signal by exposure to reflected light according to a combination of the emission and second exposure; and a distance calculator that generates a distance image by ratio operation using the first pixel signal and the second pixel signal. Timing of the first exposure is set to timing during which the sensor is not exposed to reflected waves from an object included in a first section in which a distance from the object detection device is from 0 to a predetermined value. A time difference between the emission and the second exposure is greater than a time difference between the emission and the first exposure.

  • Publication number: 20240112478
    Abstract: An object detecting device includes: a first luminance obtainer and a distance obtainer that obtain a first luminance image and a depth image, respectively; a first clustering unit that generates a group that is a set of pixels taken as the same object in the depth image, and determines that the group is a cluster when a total number of pixels included in the group is at least a first threshold; a second clustering unit that determines that the group is a cluster, when (i) the total number of pixels included in the group is less than the first threshold and (ii) luminance of a pixel group in the first luminance image which corresponds to the group is at least a second threshold; and a 3D object detector that generates 3D object information indicating an object in the depth image which is detected based on the cluster.

  • Patent number: 9407804
    Abstract: An image processing apparatus includes: a specific sound detecting section detecting a specific sound generated during motion in a specific motion of a target object included in an image group including a plurality of images which continues in a time-series manner; a valid sound range setting section setting, as a valid sound range, a range in the time axis for determination of whether the specific sound is valid on the basis of a user manipulation; and a selecting section selecting a predetermined number of motion transition images representing transitions of the specific motion from a selection range of the image group in the time axis, with reference to a detection position of the specific sound in the time axis, in a case where the specific sound is detected in the set valid sound range.

  • Patent number: 8896626
    Abstract: An image processing apparatus includes: a specific sound detecting section which detects a specific sound generated during motion of a specific motion conducted by a target object included in an image group including a plurality of images which continues in a time-series manner; a synthetic image generating section which generates a synthetic image representing transitions of the specific motion; a determination range setting section which sets, as a determination range, a range in the time axis for determination on the generation of the synthetic image on the basis of a user manipulation; and a control section which controls the synthetic image generating section to generate the synthetic image in a case where the specific sound is detected in the set determination range, and not to generate the synthetic image in a case where the specific sound is not detected in the set determination range.
