An approaching-object detection system detects an approaching object based on images captured by an imaging device. The approaching-object detection system comprises an extraction unit, a distortion correction unit, an object detection unit, and an approaching-object classification unit. The extraction unit extracts a partial image of one far side and a partial image of the other far side from each of the images. The distortion correction unit corrects distortion of the partial images. The object detection unit detects an object from the corrected partial images through pattern matching with reference to preinstalled image information on the object. The approaching-object classification unit classifies the detection result of the object detection unit as an approaching object or not.

It is possible to consider an image as a composite wave that is the result of layering waves having differing periods and amplitudes. An image captured via a lens having a water droplet attached thereto has a higher occurrence of changes such as image blur than an image that does not have a water droplet attached thereto, which means that this type of change in an image results in changes in the composite wave thereof as well. Provided is a lens dirtiness detection device that suitably determines whether a lens is dirty without being affected by a background image by: focusing on the occurrence of large changes in the composite wave of an image that accompany an increase in the dirtiness of a camera lens; extracting each of the image frequency components that constitute the composite wave; and analyzing changes in the magnitude relation between the frequency components.

Video displaying apparatus and video displaying method

In a cellular phone terminal, a bit error rate measurement section measures a bit error rate of broadcast data received by a broadcast reception section for receiving a digital broadcast to output broadcast data while a transmission operation of a communication transmission section for wirelessly communicating with a broadcasting communication network is performed. When the measured bit error rate is equal to or higher than a predetermined threshold, stopping of the transmission operation of the communication transmission section is instructed. Thus, a failure such as interruption of television broadcasting reproduction can preliminarily be prevented by avoiding error occurrence in reception of the 1 segment broadcasting service due to an influence of a transmission electric wave in data communication. As a result, stable reception of the 1 segment broadcasting service can be executed.

A radio line is easily influenced in its nature by attenuation or reflection of an electromagnetic wave or the like and the surrounding environment. Due to this fact, a variation of the data transfer speed frequently occurs at the time of image streaming so as to become a hindrance to reproduction of an image at the receiving terminal. A distribution server is provided with a multiplexer for multiplexing information indicating the transmission start time for the image data and a switching unit for switching an image bit rate in response to a request from the receiving terminal. The receiving terminal uses information indicating a transmission start time for the image data, monitors the receiving bit rate and sends out a request for transmission of the most-suitable image bit rate in response to a comparison thereof.
