In-vivo image acquiring apparatus, in-vivo image receiving apparatus, in-vivo image displaying apparatus, and noise eliminating method

摘要

An in-vivo image acquiring apparatus includes an operation control unit which controls a black image acquiring operation, in which the operation control unit controls an imaging unit and an illuminating unit in such a manner the imaging unit conducts an image acquiring operation in a state the illuminating unit does not conduct an illuminating operation. The in-vivo image acquiring apparatus also includes an average calculating unit which calculates the average value of pixel value in a predetermined determining area, and a black image determining unit, which determines whether the image information acquired by the image acquiring operation is the black image by comparing the average value with a predetermined threshold value. The image information determined as the black image by the black image determining unit is transmitted, as the black image information, to an external apparatus by radio.

主权项

1. An in-vivo image acquiring apparatus to be taken into a body of a subject, comprising:
an imaging sensor that acquires in-vivo image information; an illuminating device that illuminates imaging regions of which images are taken by the imaging sensor; a radio transmitting circuit that transmits the image information acquired by the imaging sensor to an external apparatus by radio; an operation controller that controls operations of the imaging sensor and the illuminating device so as to control a black image acquiring operation in which the imaging sensor conducts an imaging operation with the illuminating device not conducting an illuminating operation; a processor that:
detects a peak value of pixel values of pixels that constitute a predetermined determining area among the image information acquired by the black image acquiring operation; anddetermines whether the image information acquired by the black image acquiring operation indicates a black image by comparing the peak value with a predetermined threshold value, the black image being the image information that is compared with the image information acquired by the imaging sensor in an illuminating state and that is used for eliminating fixed pattern noises in the image information acquired by the imaging sensor in the illuminating state, wherein the radio transmitting circuit transmits to the external apparatus by radio the image information which is determined as the black image, as black image information.
