Abstract: A welding control device includes an actual position determination part configured to determine an actual position of the position control target on the basis of a weld characteristic amount detected from a captured image captured so as to include at least the position control target, the welding characteristic amount including at least one of a wire position of the weld wire or an electrode position of the electrode; a target position determination part configured to determine a target position being a target of the actual position corresponding to a weld condition for welding the weld target; and a position control part configured to execute a position control of the position control target to bring the actual position to the target position.

Abstract: A presentation device comprises an image capture portion for capturing an image of a subject and generating a raw image thereof; a detection portion adapted to analyze whether a first marker is present in the raw image, and if the first marker is present in the raw image, to detect an existing position of the first marker within the raw image; a storage portion for storing a positional relationship of a synthesis position at which a mask image for masking at least a portion of the raw image is synthesized with the raw image relative to the existing position of the first marker; a synthesized image generation portion adapted to determine the synthesis position according to the positional relationship with the detected existing position, and to synthesize the mask image at the determined synthesis position within the raw image to generate a synthesized image; and an output portion for outputting the synthesized image.

Abstract: An information providing system includes an information providing device and a tablet terminal. The information providing device wirelessly sends first information including a taken image, to the tablet terminal; wirelessly receives second information including information regarding a user's drawing operation on the table terminal, from the table terminal; and displays a drawn image corresponding to the user's drawing operation to be superimposed on the taken image, as a displayed image on a display, based on the second information. The tablet terminal includes an operation unit having an operating surface, on which the user performs the drawing operation.

Abstract: An information providing apparatus equipped with a camera includes: an imaging unit configured to take an image of a preset area with the camera and obtain the taken image; a display output module configured to display the taken image as a displayed image on an image display device; a receiver configured to wirelessly receive operating information, which regards a user's operation performed via a pointing device and includes at least coordinates-related information, from the pointing device; and an operating information processor configured to perform processing based on the received operating information and display result of the processing to be superimposed on the displayed image, wherein the imaging unit, the display output module, the receiver and the operating information processor are all accommodated in a single housing.

Abstract: An information providing device takes an image of a predetermined area and obtains the taken image in the form of image data, while externally obtaining voice data representing speech. The information providing device obtains text in a preset language corresponding to the speech in the form of text data, based on the obtained voice data, generates a composite image including the taken image and the text in the form of composite image data, based on the image data and the text data, and outputs the composite image data.

Abstract: A presentation device 100 comprises an image capture portion for capturing a subject at prescribed time intervals to generate successive raw images; a first storage portion to which the generated raw images are successively saved; a second storage portion to which one of the generated raw images is saved as a still image; a detection portion adapted to analyze raw images stored in the first storage portion to ascertain if a prescribed indicator member is included therein, and if the indicator member is included in the raw images, to detect the location and direction of pointing of the indicator member; a pointer image generation portion adapted to generate a pointer image showing the detected location and direction; a synthesized image generation portions adapted to read out the still image from the second storage portion and synthesize the pointer image with the still image to generate a synthesized image; and an output portion for outputting the synthesized image.
