A point which requires visual attention is added to map data. A map data generation device acquires image data in which the outside is captured from a vehicle by an input device and a point data of the vehicle, associates both data, and generates a visual saliency map acquired by estimating fluctuation of visual saliency based on the image data by the visual saliency extraction unit. Then, whether or not a point or a section indicated by position information corresponding to the visual saliency map is a point or a section which requires visual attention is analyzed based on the visual saliency map by an analysis unit, and the point or the section which requires the visual attention is added to the map data based on an analysis result of the analysis unit by an addition device.

Map data generation device

Power transmitting apparatus

Disclosed is an image data processing method capable of reducing visual discomfort perceived by users in the recovery from a receive error in a receiver. According to the image data processing method, in recovery processing of a video motion damper system in an image data processing circuit, a frequency of occurrence of the receive error before and after the time of recovery from the receive error is judged. According to the judgment result, the time period for switching of the output tap in recovery processing is adjusted. When the frequency of occurrence of the receive error is high, the recovery processing is halted until the selected tap position during the recovery is returned to the output tape position of the first FIFO of a frame memory.

Image data processing circuit

A broadcast receiver which detects the reception status of radio waves from other stations without deteriorating the reception status of a currently-receiving station, in digital broadcasting where consecutive time series data is transmitted. The amount of time-based interleave applied to the currently-receiving data is determined so that the reception status of the radio waves from other stations is detected while the reception of the currently-receiving broadcast station is interrupted within the extent where missing data can be recovered by such interleave and error correction processing on demodulation.

Broadcast receiver

An S/N ratio measuring method of a video signal which is suitable for the formation of an IC and can precisely detect a fluctuation of an S/N ratio of a video signal at high response speed while suppressing the total cost and a system based on this method. In operation, a composite video signal is received, a noise density in a predetermined period of the composite video signal is detected, and an S/N ratio of a video signal included in the composite video signal is recognized basis on the detected noise density. The S/N ratio measuring system has a demodulator for demodulating the composite video signal from the reception signal and a counter for counting noises which are generated in a predetermined period of time of the composite video signal and recognizes the S/N ratio of the video signal included in the composite video signal based on a count value obtained.
