A monitoring system includes an arithmetic processor. The arithmetic processor receives captured image information representing a captured image obtained by capturing an image of a subject and generates notification information representing a particular notification content depending on a condition of the subject. The arithmetic processor includes a first arithmetic processor and a second arithmetic processor. The first arithmetic processor obtains a condition quantity by quantifying the condition of the subject by reference to the captured image information and based on a parameter about a human activity status. The second arithmetic processor selects, according to the condition quantity, the particular notification content from contents of notification classified into N stages, where N is an integer equal to or greater than three.

A waveform equalization control device includes a waveform equalizer that has a filter provided with a plurality of taps, updates the tap coefficient of each of the plurality of taps in accordance with a tap coefficient signal inputted thereto, causes the plurality of taps to respectively receive a plurality of values sampled at different time points from an input signal, performs waveform equalization with respect to the input signal, and outputs the signal after the waveform equalization, an equalization target value generation unit for determining an equalization target value, an error estimation unit for obtaining the error between the equalization target value and the signal after the waveform equalization, and a coefficient update unit for determining an amount of updating the coefficient of each of the taps of the filter of the waveform equalizer based on the error signal and on the input value to each of the taps and outputting the amount of updating the tap coefficient as the tap coefficient signal. The equalization target value generation unit obtains sign signals each showing whether the signal after the waveform equalization has a positive value or a negative value for first to fifth time points and determines a value corresponding to a total sum which is a sum of respective results of multiplying the sign signals for the first to fifth time points by &#x3b8;, &#x3b2;, &#x3b1;, &#x3b2;, and &#x3b8; (where each of &#x3b1;, &#x3b2;, and &#x3b8; is a predetermined real number) as the equalization target value.
