Abstract: A fire detection device luminance data over a time period longer than a repetition period of movement of a flame, to generate resampled data, and a device that calculates an average value of N (natural number equal to or larger than 2) items of the resampled data, and determines that the input image is an image of a flame, by comparing a count of sampled data items larger than the average value, or a count of sampled data items smaller than the average value, with a predetermined value.

Abstract: An image processing device having an improved image processing speed and capable of detecting an object at high speed. Where frames are thinned out for real-time processing during frame processing of an image signal, line interval expanding unit expands the interval between lines of the image signal by an amount corresponding to the number of the frames thinned out. Image processing unit performs line processing of the lines whose interval has been expanded, according to pipeline control.

Abstract: A fire detection device that is inexpensive, capable of monitoring a wide range of area, and efficiently detecting a fire with high accuracy without necessitating a complicated image processing. Luminance data extraction means extracts luminance data from an input image. Resampling means carries out resampling of the luminance data over a time period longer than a repetition period of swaying of a flame, to generate resampled data. Fire detection means calculates an average value of N (natural number equal to or larger than 2) items of the resampled data, and determines that the input image is an image of a flame, by comparison between a count of sampled data items larger than the average value or a count of sampled data items smaller than the average value and a predetermined value.

Abstract: A detecting device for road monitoring which detects traveling states of vehicles on a road (traffic stagnation, stopping of vehicles, etc.) or fallen objects on a road is provided. Luminance change detecting unit prepares background image data by taking a time average of luminance for each picture element, and detects image portions where inputted image data is different in luminance from the prepared background image data. Hue change detecting unit prepares background image data by taking a time average of hue for each picture element, and detects image portions where inputted image data is different in hue from the prepared background image data.
