Abstract: A visual servo system includes a robot that handles an object, an irradiation device that irradiates light onto the object, and a camera that captures an image of the object and outputs a current image. The visual servo system reads, from a storage medium, a target image that is assumed to be captured by the camera when the object is in target position and attitude, and the light irradiated from the irradiation device is striking the object. The visual servo system calculates control input to be inputted to the robot based on a difference in luminance value between the current image and the target image, and inputs the control input to the robot. The light that is irradiated by the irradiation device is light that has a luminance distribution based on a reference image in winch a luminance value changes along a predetermined direction.

Abstract: A storage device relating to one aspect of the present invention has a storage controller and multiple memory devices. The memory devices manage capacity equivalent to the size of a memory space provided to the storage controller among regions of a non-volatile storage medium as logical capacity and manage the remaining regions as reserve capacity. When a device controller determines that a portion of the memory regions in the non-volatile storage medium is in an unusable state, the device controller notifies the storage controller of the size of the memory regions in the unusable state. On the basis of a policy set by the memory device, the storage controller determines the reduction amount of the logical capacity and the reserve capacity and notifies the memory device of the determined reduction amount of the logical capacity.
