Abstract: The object detection device according to the present invention includes: an image obtainer configured to obtain, from a camera for taking images of a predetermined image sensed area, the images of the predetermined image sensed area at a predetermined time interval sequentially; a difference image creator configured to calculate a difference image between images obtained sequentially by the image obtainer; and a determiner configured to determine whether each of a plurality of blocks obtained by dividing the difference image in a horizontal direction and a vertical direction is a motion region in which a detection target in motion is present or a rest region in which an object at rest is present. The determiner is configured to determine, with regard to each of the plurality of blocks, whether a block is the motion region or the rest region, based on pixel values of a plurality of pixels constituting this block.

Abstract: A tool system is used for a plurality of tools. Each of the plurality of tools is a portable tool and includes: a driving unit to be activated with power supplied from a power source; and an image capturing unit. The tool system includes a reference image generating unit and an output unit. The reference image generating unit generates, based on a second captured image, a reference image to be compared with a first captured image. The first captured image is shot, while a current work target is being identified, by the image capturing unit. The second captured image is also shot by the image capturing unit. The output unit makes a display unit display the second captured image while the reference image generating unit is generating the reference image.
