Abstract: Monitoring target person monitoring device, method, and system according to the present invention sense a predetermined event regarding a monitoring target person to notify the event; acquire an image including at least a video; determine, based on the acquired image, whether or not multiple persons are on the image; and start, in a case where it is determined that the multiple persons are on the image, storing the acquired video to store the video in a video storage.

Abstract: Disclosed is an image forming apparatus that makes it possible to suppress the scale enlargement of the electric circuit, so as to make the apparatus highly flexible. The apparatus forms an image based on image data acquired by applying a rendering operation to depiction commands and includes: a converting section to convert input data to the depiction commands; a first rendering section to apply the rendering operation to a first depiction command; a second rendering section to apply the rendering operation to a second depiction command; a reading section to read out first information from the storage section; a determining section to determine whether the first rendering section or the second rendering section should apply the rendering operation to each of the depiction commands; and a control, section to make either the first rendering section or the second rendering section apply the rendering operation to each of the depiction commands.

Abstract: An image forming system comprising: a controller, provided with a list creation means to create a display list by analyzing PDL data, a decompression means to decompress compressed image data, a drawing means to execute drawing based on the image data, and a print data creation means to create the print data based on the image data, for sending the print data to a printer; and a rasterization accelerator, provided with a second drawing means to execute drawing processing based on the display list, and a compression means to compress the image data drawn by the second drawing unit, for sending the image data to the controller, wherein the rasterization accelerator comprises a determination means for determining, based on the information of the display list, whether to execute or not the compression of the image data, and a compression method in case of executing the compression.

Abstract: Epipolar lines of first and second images are made consistent with each other in a paralleling step, so that it has the advantages (1) and (2) as set forth in the background section. Further, distortions of the first and second images are corrected in a correcting step, and, even if characters conversion is carried out, it can avoid excessively reduction of central portions in the first and second images or excessively enlargement of side edge portions. Thus, while maintaining of the above mentioned advantages (1) and (2), wide angle image acquiring method and a wide angle stereo camera device which make three-dimensional space holding possible can be provided.
