The present invention provides a surroundings monitoring apparatus and a surroundings monitoring method which can reduce, in a displayed image, distortions caused by camera position displacement in the case where the camera position displacement is present. The surroundings monitoring apparatus includes: a position displacement information obtainment unit which obtains a degree of the position displacement in each camera and outputs it as camera position displacement information; a moving object state detection unit which detects vehicle speed, a shift lever, and a steering angle of a vehicle and outputs them as a moving object state; a coordinate transformation parameter selection unit which selects a coordinate transformation parameter according to the camera position displacement information; an image synthesis parameter selection unit which selects a reference image synthesis parameter and a graphics parameter according to the moving object state; a coordinate transformation unit which performs coordinate transformation on image coordinates of a captured image which are included in the reference image synthesis parameter using the coordinate transformation parameter and outputs the image coordinates as a transformed image synthesis parameter; and an image synthesis unit which generates a synthetic image according to the transformed image synthesis parameter and outputs the generated synthetic image.

An optical scanning device has a light shield plate where a scanning line emitted from a light source passes through a scanning lens, and is reflected by a rotation polygon mirror, and after that, passes through the scanning lens again, and is reflected by the scanning lens at the opposite side of the rotation polygon mirror by nipping the scanning lens, wherein the light shield plate is placed at a position wherein the distance between the rotation polygon mirror and the scanning lens, the thickness in the optical axial direction of the scanning lens, the angle by which the scanning line incident the rotation polygon mirror and the convergent angle of the scanning line satisfies a certain relationship.

A parameter selection section selects one from a plurality of image synthesis parameters stored in a parameter storage section according to an output of a vehicle state detection section. An image synthesis section reads out camera images from frame memories according to the selected image synthesis parameter and generates a synthesized mage showing a state of vehicle surroundings. A moving object detection section detects, in the thus generated synthetic image, a moving object region estimated as a region where a moving object is present.

In an optical transmission node network in which a first optical transmission node is connected with a second optical transmission nodes through an optical fiber cable and automatic optical output (APSD: Automatic Power Shut-Down) control is activated, after the APSD control is brought into an inhibited status, if an optical conduction to the second optical transmission node is detected, the APSD control inhibited status is canceled. In this way, if an optical transmission fiber is resorted (reconnected) after optical output power measurement or the like is carried out, the APSD control inhibition status (invalid status) is canceled for automatically restoring the APSD control activated status. Thus, optical output can be prevented from being inadvertently emitted at a high energy level from the optical fiber cable.

An image forming apparatus includes an image forming section, a page memory for storing at least one page of image data to be transferred to the image forming section, and a DMA (Direct Memory Access) controller. The page memory is implemented by a DRAM (Dynamic Random Access Memory). The DMA controller continuously transfers, in response to a single DMA request received from the image forming section, a plurality of words of image data with the same row address from the DRAM to the image forming section at a time by DMA transfer. The apparatus is capable of transferring image data from the DRAM to the image forming section at a high speed by DMA transfer. This is also true when the image data are rotated by 90 degrees or 270 degrees. Further, the apparatus is capable of accurately setting a position where the image forming section starts recording image data on a line.

Power lines include three or more conductors for transmitting alternating currents. The conductors are arranged in one combination of the conductor arrangement so that the sum of phase differences between the currents flowing through adjacent conductors is maximum, and if there exists a plurality of such combinations, the one combination is selected in which the value of the smallest one of the phase differences between the currents flowing through every adjacent conductor is largest. With this arrangement, power loss is reduced.

A recording apparatus that can implement an endless recording function and a prealert recording function for video and audio data using a single random access recording medium having excellent random accessibility will be provided. The recording apparatus includes: an input section 101 that receives data; a recording section 103 that has a random access recording medium and makes a data recording onto the random access recording medium; and a control section 104 that sequentially records data onto recording sectors by controlling data transfer between the input section and the recording section. By causing the control section to repetitively overwrite data to a recording area, the endless recording function can be implemented.

To implement a system minimizing access to the shared memory, the previous owner number storage module contains the number of a cache memory or the shared memory which was the previous owner of data. When the cache control module expels a copy of data from the snoop cache memory module, it references the previous owner number storage module and, if it contains the number of a cache memory, passes the ownership to the snoop cache memory module with that number.
摘要:
In a CATV-LAN in which a plurality of modems transmit messages asynchronously from respective terminal apparatuses to an upstream transmission path and receives messages from a downstream transmission path, when a modem is transmitting a message, the resultant data which are received by that modem are compared with data of that message which have already been transmitted, and transmission is interrupted if the received data do not correctly match the transmitted data, due to conflict with data transmitted by some other modem. Each message contains information specifying its length, and when a non-transmitting modem receives a set of data whose actual length does not match a length value which is specified within the data, the data are discarded. It thereby becomes unnecessary to provide beat detection circuits in the modems, for detecting data conflict, so that system cost can be reduced.

A dense substrate for a solid oxide fuel cell, comprising: a base portion, support portions and fixing portions all of which project from the base portion so as to be arranged sequentially in one direction; grooves formed between the support portions and the fixing portions or between the support portions; and mount portions which are provided on the support portions between the fixing portions for mounting and affixing at least cell sections thereon. A solid oxide fuel cell is easily manufactured at a reduced cost by arranging a plurality of cell sections and, if required, plate sections, on the mount portions of the above dense substrate; affixing the cell sections and, when used, plate sections, onto the mount portions with an insulating bonding agent; and joining adjacent cell sections together with interconnections.
