Abstract: A range finding device includes a light-emitting unit including light-emitting regions; an optical element to guide light emitted from the light-emitting unit; a light-receiving unit including light receiving regions to receive light reflected from an object; and circuitry to control light emission amount of the light-emitting regions; measure an amount of light received at the light receiving regions; measure a distance to the object by measuring a time difference between a start time when the light is emitted from the light-emitting unit and a time when the light reflected from the object is received by the light receiving regions; cause the light-emitting regions to emit the same light amount as a preliminary light emission stage; control the light emission amount of the light-emitting regions for a main light emission stage based on the amount of light measured at the preliminary light emission stage; and measure the distance to the object.

Abstract: An image processing apparatus for processing images captured by an image capturing apparatus includes an image input unit to receive a plurality of image frames of a subject captured by the image capturing apparatus along the time line; a tracking area setting unit to set a target tracking area on the plurality of image frames; a tracking unit to track the target tracking area on the plurality image frames; a subject condition prediction unit to predict a condition of the subject at a time point delayed from a time point when the most recent image frame of the plurality of image frames is captured based on a tracking result of the target tracking area; and a parameter setting unit to set a parameter to be used for an image capturing of the subject based on the predicted condition of the subject to the image capturing apparatus.

Abstract: An image signal processing unit partitions a frame image into a plurality of partitioned blocks and calculates for each partitioned block luminance information, color information, contrast information, and a motion vector quantity. A grouping unit groups the partitioned blocks into an image area of the same object based on the luminance information and the color information of each partitioned block. A moving amount calculating unit calculates a moving amount of an object contained in a grouped image area based on the motion vector quantity of each partitioned block, a detection value of a motion detection sensor, and a focal length calculated by a focal length calculating unit. A tracking object selecting unit selects an object in the image area of the highest contrast value as a tracking target object out of objects each having a moving amount exceeding a threshold value.

Abstract: An imaging apparatus includes an imaging device configured to image an object, a sound receiving device configured to receive an ambient sound, a phonation determining device configured to determine whether the object imaged by the imaging device is producing a sound or not, an object characteristic determining device configured to determine a characteristic of the object if the phonation determining device determines that the object is producing the sound, a band determining device configured to determine a band of the ambient sound which suits the characteristic of the object and emphasize the band in the ambient sound, and a recording device configured to record the ambient sound in which the band is emphasized.
