Abstract: A traffic sign recognition device includes a storage device configured to store a camera image from a movable body and pieces of three-dimensional point group data, and a processor. The processor is configured to: estimate a relative position of the traffic sign candidate to the movable body; specify a set of three-dimensional point group data; and specify an image region of an object corresponding to a set region indicative of a region where the set is specified, the object including the traffic sign candidate. The processor is configured to calculate a percentage of a predetermined color component constituting a guide sign among color components constituting an image of the object. In a case where the percentage of the predetermined color component is equal to or more than a threshold, the processor recognizes the object including the traffic sign candidate to be the guide sign.

Abstract: Providing a medical image storage unit that stores a medical image, an image processing unit that performs image processing on a medical image to be stored in the medical image storage unit and stores the result of the image processing in association with the medical image, and a past medical image identification unit that identifies, at a storage time point of a new storage target medical image in the medical image storage unit or at a time point before the storage time point, a past medical image related to the new storage target medical image from the medical images stored in the medical image storage unit, wherein the image processing unit performs the same image processing as that for the new storage target medical image on the identified past medical image and stores the result of the image processing in association with the past medical image.
