Abstract: A photoacoustic microscope includes a light source, an objective lens, a light scanner, a photoacoustic wave detector, and a calculation unit. The light source emits excitation light. The objective lens focuses the excitation light within a specimen. The light scanner scans the specimen with the excitation light. The photoacoustic wave detector detects photoacoustic waves. The calculation unit uses a correlation coefficient to calculate a shift in waveform due to a change over time in photoacoustic waves between a standard position and a calculation position. The calculation unit calculates the depth from the standard position at the calculation position based on the shift.

Abstract: An inkjet printing apparatus uses a printing head including a plurality of nozzle arrays each including a plurality of nozzles arrayed in a first direction, the nozzle arrays being arranged in a second direction. A compensating unit compensates for an ejection failure of a defective nozzle by causing a compensating nozzle to eject ink to a predetermined pixel area in a case where the print data corresponding to the defective nozzle indicates ink ejection to the predetermined pixel area. The compensating unit determines the compensating nozzle such that the compensating nozzle satisfies both a first condition that the compensating nozzle is not a defective nozzle and a second condition that the print data indicates that nozzles belonging to the nozzle array including the compensating nozzle do not eject ink to a pixel area corresponding to N pixels (N is a positive integer) around the predetermined pixel area in the first direction.
