An obstacle detection device () is provided with a distance measurement sensor () which measures a detection distance to an object to be detected, a detection image generation unit () which generates a detection image indicating a presence of the object to be detected in a detection range, based on a result of measurement by the distance measurement sensor (), a rainfall determination unit () which performs a rainfall determination of whether or not a region in the detection range is in a rainfall state, a rain removal processing unit () which executes a rain removal process for removing the isolated points from the detection image, and an obstacle determination unit () which performs an obstacle determination of whether or not the object to be detected is an obstacle. The obstacle determination unit () performs the obstacle determination, based on the detection image on which the rain removal process is performed by the rain removal processing unit (), in a case where a region is determined to be in the rainfall state by the rainfall determination unit ().

Obstacle detection device, moving body, and obstacle detection method

A moving body () according to the invention includes: a drive unit (); a control unit (exemplified by a drive control unit () and a speed instruction unit ()) that controls driving by the drive unit (); an object recognition unit () that recognizes an object; and a determination unit (exemplified by a degree-of-risk determination unit ()) that, in accordance with a recognition result by the object recognition unit (), determines a degree of risk of collision with the object. In a case where determination is made as being risky by the determination unit, the control unit performs control of reducing a target speed of the moving body (), and returns the target speed of the moving body () to the original one, in a case where determination is made as being safe by the determination unit for a predetermined period in a state where the target speed has been reduced.

Each liquid crystal display device of a multi-display system includes a light intensity correcting section, which performs a light intensity correction in which backlight intensity of each of light intensity control areas belonging to a liquid crystal display device including the light intensity correcting section is corrected in accordance with backlight intensities of adjacent areas which are adjacent to the light intensity control area. In a case where another liquid crystal display device which is adjacent to the liquid crystal display device including the light intensity correcting section includes one of the adjacent areas, the light intensity correcting section accesses to the another liquid crystal display device via the communication section so as to obtain the backlight intensity of the one of the adjacent areas, in order to perform the light intensity correction in accordance with the obtained backlight intensity of the adjacent area.

Multi-display system with backlight intensity correction

It is expected to provide a display system, display control method and computer program for effectively outputting sound with plural display apparatuses in a two dimensional array. A control apparatusis connected to a two dimensional array display apparatus unit made with display apparatuses, . . . configuring a multivision system. A controlling unitof the control apparatusobtains position information for the display apparatus unit in the two dimensional array. Based on the position of each display apparatusin the two dimensional array display apparatus unit, the controlling unitdecides the presence or absence of output sound and selects the channel for the output sound.
