Abstract: Edges of layers are detected from an input image to create a boundary line candidate image that represents the detected edges. A luminance value of the input image is differentiated to create a luminance value-differentiated image that represents luminance gradient of the layers. An evaluation score image is created which is obtained by weighting calculation at an optimum ratio between a boundary line position probability image and the luminance value-differentiated image. The boundary line position probability image is obtained from the boundary line candidate image and an existence probability image that represents existence of a boundary line to be extracted. A route having the highest total evaluation score is extracted as the boundary line. According to such an image processing apparatus and image processing method, boundary lines of layers can be extracted with a high degree of accuracy from a captured image of a target object composed of a plurality of layers.

Abstract: A bioinformation acquiring apparatus includes at least one processor and a memory configured to store a program to be executed in the processor. The processor acquires a waveform signal representing vibrations of a target, the vibrations resulting from heartbeats of the target; extracts provisional heartbeat timings from the acquired waveform signal based on a first time window; the provisional heartbeat timings indicating provisional values of heartbeat timings being timings at which the heartbeats of the target occur; acquires corrective peak timings from the acquired waveform signal based on a second time window having a shorter time length than the first time window, each of the corrective peak timings serving as a discrete correction unit for correction of the provisional heartbeat timings; corrects the extracted provisional heartbeat timings into definitive heartbeat timings based on the acquired corrective peak timings; and acquires bioinformation on the heartbeats of the target based on the corrected heartbeat timings.

Abstract: An image processing apparatus of the present invention acquires a photographed image of an object on which indicators have been arranged, detects the indicators from the photographed image with use of a comparison reference image for pattern matching prepared in advance, and instructs to perform predetermined processing based on the detected indicators. The indicators each have a pattern where influence of geometrical image distortion generated corresponding to a photographing distance or a photographing angle with respect to the object is restrained by a central portion of the photographed image, and the comparison reference image is a partial image corresponding to a central portion of the indicator. The indicators are detected from the photographed image by comparing the comparison reference image with the acquired photographed image.

Abstract: An autonomous mobile apparatus includes a controller, an image acquirer, an inertia measurer, a distance measurer, and a storage. The controller updates environment map information stored in the storage. The controller estimates a height from a reference surface, based on an image obtained by the image acquirer. The inertia measurer detects an amount of fluctuation of the height. The distance measurer detects whether or not the bottom portion of the autonomous mobile apparatus is in contact with an object. The controller, if having detected a change in height equal to or larger than a reference from information obtained from the image acquirer, the inertia measurer, or the distance measurer, stops updating the environment map information or deletes the environment map information.
