A sphygmomanometer according to the present invention includes an air leakage testing unit that performs air leakage testing on an air system to obtain an air leakage testing result, and a storage unit that stores the air leakage testing result. The air leakage testing result stored in the storage unit is displayed, on a display device, in a first display mode during a transition from a power-off state to a standby state or a non-blood pressure measurement state where a measurement start operation is disabled, or during a transition from the standby state to the power off state or the non-blood pressure measurement state where the measurement start operation is disabled, whereas, in the standby state or during blood pressure measurement, the air leakage testing result is not displayed or is displayed in a second display mode lower in degree of enhancement than the first display mode.

A pressure sensor for detecting a pulse wave, a digital conversion unit for converting a pressure signal from the pressure sensor into a digital signal, and a fourth derivative filter having an adjustable frequency characteristic for obtaining a fourth derivative wave of an original waveform based on the digital signal generated by the conversion by the digital conversion unit are provided. Local extrema of the fourth derivative wave in a section of the pulse wave corresponding to one beat are calculated. Based on the calculated local extrema, an early systolic component and a late systolic component are calculated.

A circuit board with lead-free solder is inspected by using light sources with different colors at different angles to obtain an image having a plurality of color components. For each pixel within an area in the obtained image, the brightness of a white component generated by mixing all of the color components is extracted. The brightness of each of the color components of each pixel is reduced by an amount corresponding to the extracted brightness of the white component and is adjusted such that the brightest of the color components becomes more strongly emphasized compared to the others, than the brightness before the brightness-reducing process was carried out and the loss in total brightness caused by the brightness-reducing process is restored. The image with restored brightness is displayed and the surface condition of the solder is judged on the basis of the distributions of the color components of this image.
