A terminal apparatus includes a display device; a first sensor configured to detect a proximity state of being in proximity to an object different from the terminal apparatus; a second sensor configured to detect vibrations; and a processor, wherein the processor determines whether or not a first detection value acquired from the first sensor indicates that the terminal apparatus is in the proximity state, turns off a backlight of the display device in accordance with the first detection value, and acquires, when it is determined that the first detection value does not indicate that the terminal apparatus is in the proximity state, a second detection value from the second sensor, determines whether or not the second detection value, which has been acquired, indicates that the terminal apparatus is vibrating, and turns off the backlight of the display device in accordance with the second detection value.

Terminal apparatus, backlight control method, and backlight control program

An information processing apparatus is disclosed, including a detection part, a change part, and a determination part. The detection part detects a change of a first color temperature of an external environment. The change part changes a second color temperature of a display part at a predetermined speed to a targeted value corresponding to the first color temperature after the change in response to a detected change of the first color temperature. The determination part determines whether brightness of an image is changed, in response to a switch of the image on the display part. When it is determined that the brightness of the image on the display part is changed during the change of the second color temperature of the display part, the change part changes the second color temperature of the display part at a different speed from the predetermined speed.

Information processing apparatus and display control method

A tele-inventory system for inventorying various kinds of commodities in a shop by an operator from a remote management apparatus installed remotely from the shop, includes, at shop, a camera for taking images of object commodities to be inventoried, a image-transmitter for transmitting the taken images of the object commodities to the remote management apparatus, and, at the remote management apparatus, an image-receiver for receiving the taken images of the object commodities from the image-transmitter and display for displaying the taken images of the object commodities, whereby the operator can make an inventory of the object commodities at the remote management apparatus with consulting the taken images of the object commodities which images have been displayed on the display. With this system, it is possible to inventory commodities sold and stocked in a department store or a convenience store from a remote place.

Tele-inventory system, and in-shop terminal and remote management apparatus for the system

A robot for freely moving about in an environment where there is an obstacle. The robot includes a communication section transmitting by wireless an image taken by a camera to a base station, and via the base station to a communication terminal making a radio communication with the base station, and receiving by wireless movement target position information specified on the image by an operation of the communication terminal via the base station, and a motion control section that moves the robot up to a movement target position specified by the movement target position information acquired in the communication section.

Robot

A remotely controlled robot comprises a unit storing the layout plan of a building, a unit receiving a position remotely designated in the layout plan from a remote location and a unit controlling the travel of the robot to the designated position. A self-position identification method is implemented by a robot with a camera whose shooting direction can be changed. The robot takes in advance a panoramic picture of a room where the robot may travel, generates a reference picture by extracting a plurality of block pictures from the panoramic picture and identifies a room where the robot is located, by applying correlation and DP matching, using both a picture taken in the room where the robot is located and the reference picture.

Remote-controlled robot and robot self-position identification method

In an image processing unit for performing an arithmetic operation between a reference image and a search image, a product-sum operation section comprises systoric array, a normalization and accumulation processing section and a correlation value memory control section. The product-sum operation section is used on a common basis for an operation for the addition of a square of a pixel value of a search image over a plurality of pixels and an operation for the addition of a multiplication of pixel values of pixels associated with the search image and the reference image over a plurality of pixels. An operation for a norm of the reference image is performed on a path (a reference image norm computing section) which is different from that of the product-sum operation section.

Image processing unit

A local region image tracking apparatus continuously tracks an arbitrary local region within a search image which is described by search image data by comparing the search image data and reference image data related to the arbitrary local region having a size of am pixels by bn pixels with respect to input image data, where the search image has a size larger than am pixels by bn pixels, and,, b, m and n are natural numbers. The local region image tracking apparatus includes correlation computing circuit for computing a correlation between reference image data related to a reference image having a size of m pixels by n pixels and the search image data a plurality of times while moving a position of the reference image with respect to the search image, and for outputting correlation values respectively indicating a computed correlation, and a correlation value accumulating circuit for accumulating the correlation values output from the correlation computing circuit, and for outputting a correlation value indicative of a correlation between the search image data and reference image data related to an equivalent of a reference image having a size of am pixels by bn pixels.

Image tracking apparatus for tracking an image within a local region to continuously track a moving object

A local region image tracking apparatus continuously tracks an arbitrary local region within a search image that is described by search image data by comparing the search image data to be subjected to a tracking process out of input image data picked up by image pickup means with reference image data related to the arbitrary local region. The local region image tracking apparatus includes an image data bus transferring the input image data from the image pickup means, and a plurality of correlation tracking processors coupled in parallel to the image data bus and respectively capable of independently carrying out the tracking process with respect to at least one search image, where the tracking process with respect to one or a plurality of search images is distributively carried out by the correlation tracking processors.

Tracking apparatus for tracking image in local region

A system for and a method of recognizing and tracking a target mark with a video camera is disclosed. The system includes a target mark (10) disposed on an object (1) and composed of a black circle and a white triangle mounted centrally on the black circle and three-dimensionally shifted from the black circle, a video camera (20) for imaging the target mark (10), a robot (30) supporting the video camera (20) and movable in directions with six degrees of freedom, an image processor (40) for processing image data of the target mark which is produced by the video camera (20), a shift calculating unit (50) for detecting a shift of the target mark (10) from projected histogram information of the target mark (10) which is produced by the image processor (40), and a robot controller (60) for controlling movement of the robot depending on the shift to enable the video camera (20) to track the target mark (10). The system is capable of tracking the target mark (20) attached to the object (1) on a real-time basis. Mark recognizing apparatus capable of accurately recognizing target marks of other shapes is also disclosed.
