An influence on object expression performed at a transmission destination is reduced. A position information reception unitof an information integration devicereceives, regarding objects which are measured by a plurality of sensors from a plurality of locations and overlap in any of the locations, position information for each location on areas of the objects. A position information integration unitcalculates smallest rectangles or largest rectangles surrounding the objects by using the position information for each location.

Information integration method, information integration device, and information integration program

The present invention is to improve accuracy of position information of an object. A labeling unitof an information integration deviceassociates a label included in tracking data with an object area having a largest ratio of overlapping areas overlapping label areas included in the tracking data with regard to the object area or an object area having a largest size of overlapping areas overlapping label areas included in the tracking data, among a plurality of object areas included in a Depth map.

Performance of an encoding process and a decoding process for a sound signal is enhanced. A representative value calculating partcalculates, for each frequency section by a plurality of samples fewer than the number of frequency samples of a sample sequence of a frequency domain signal corresponding to an input acoustic signal, from the sample sequence of the frequency domain signal, a representative value of the frequency section from sample values of samples included in the frequency section, for each of predetermined time sections. A signal companding partobtains, for each of the predetermined time sections, a frequency domain sample sequence obtained by multiplying a weight according to a function value of the representative value by a companding function for which an inverse function can be defined and each of the samples corresponding to the representative value in the sample sequence of the frequency domain signal, as a sample sequence of a weighted frequency domain signal.

Matching timings of transmitting pieces of information for reproducing video and audio with presence and handling loss are provided. An information synchronization device is configured to synchronize, to a reference timestamp, data in which one or more labels for identifying respective one or more subjects on a video and one or more pieces of location information for identifying respective locations of the one or more subjects are respectively associated. The information synchronization device includes a reception unit for receiving the data at each time, a buffer for storing the received data, and a location information interpolation unit for generating, when pieces of the location information at times before and after the reference timestamp is stored into the buffer for any of the labels, location information of the label at the reference timestamp by interpolation using the pieces of the location information.

A developing sleeve used in a developing device of an electrophotographic apparatus is composed of a sleeve base and an electrodeposition coating formed on the surface of the sleeve base. The electrodeposition coating contains an electrodepositable resin and an electroconductivity-controlling powdery matter, which can be a powdery ceramic, with or without a powdery metal. A developing device for developing an electrostatic latent image and an image-forming apparatus including this developing sleeve are disclosed.

Disclosed is an image heating device for a fixing device in image forming apparatus. The image heating device is provided with two heaters and an image fixing roller. The image fixing roller is heated by the two heaters, one having the heat distribution in the center and the other having the heat distribution in the end portion of the fixing roller. The heaters are alternately energized so that the power requirement is maintained limited. The energization time ratio of the heaters is suitably varied according to the sheet size in order to compensate the temperature loss in the end portions when the heating is conducted in the central portion only, or to reduce the temperature rise in the end portions, encountered when narrow sheets are consecutively passed, thereby preventing various drawbacks resulting from uneven temperature distribution on the fixing roller.

Disclosed is an image forming apparatus capable of preventing the offset phenomenon and an electrostatic adhesion jam. The surface of a photosensitive body is uniformly charged by a corona charge device, and then an image of the reflected light from an original is projected on the photosensitive body to obtain an electrostatic latent image. Subsequently, a developer develops the latent image into a visible image with toner. The visible image is, then, electrostatically transferred onto a transfer medium by a charge means. After that, static electricity in the transfer medium is removed by a separation means so as to be separated from the photosensitive body and to be sent to a fixing device.
