摘要： A total-focus imaging apparatus comprises a variable-focus lens unit with a focal position thereof changeable at high speeds, a CCD element, a microcomputer and a liquid-crystal display unit. The microcomputer includes an image memory, an image processing circuit and a control circuit. The variable-focus lens unit and the CCD element allow an object of observation to be photographed to generate a number of images with the focal positions thereof slightly different from each other and the image to be stored in the image memory. Pixels each brought to a focus are selected by the image processing circuit from pixels of the images to generate an image of the observation object comprising only pixels each brought to a focus. Such an image is then displayed on the liquid-crystal display unit. Thus, an image of the observation object which is all but completely brought to a focus can be presented in a semi-real-time manner. An image of an observation object all but completely brought to a focus is an image with all portions of the observation object brought to a focus.

摘要： In a pulse wave analyzer, an ECG signal and a pulse wave signal are detected from an object to be analyzed. A plurality of feature points are extracting from the acquired ECG signal, the feature points appearing in a waveform of the ECG signal. The acquired pulse wave signal is segmented into a plurality of pulse wave signal pieces based on times at which the feature points appear. Each of the pulse wave signal pieces is segmented every heart beat. A reference pulse wave is calculated based on the plurality of pulse wave signal pieces, by multiplying the pulse wave signal pieces by coefficients and averaging the pulse wave signal pieces multiplied by the coefficients. The reference pulse wave is used to estimate the blood pressure of the object.
