Abstract: A condition for determining that an examination by a capsule endoscope 3 (body insertable device) completes is set in advance. When a predetermined time period has passed since the examination starts, and when received electric-field strength of receiving antennas A1 to An detected during a predetermined time period is not higher than a predetermined value, the examination is determined to have been completed. An examination completion determining unit C1 determines whether the condition is satisfied or not. According to the result of determination, a notification controller C2 makes a notifying unit 15 notify that the examination completes, and a power supply controller C3 stop power supply to a radio unit 2a. Thus, unnecessary power consumption is prevented and the completion of the examination by the body insertable device is recognized.

Abstract: A method of adaptive local image similarity measurement based on the L1 distance measure is described. A relationship between distance measures is used to estimate appropriate thresholds for various patch sizes. The choice of patch size depends on the degradations contained in the image and the application. The relation between the similarity measures is established using the distribution of L1 distances for various patch sizes. For larger degradations, similarity measure with a bigger patch size is employed. For lesser imperfections, a smaller patch size produces acceptable results. To keep the computational overhead manageable, the smallest patch size that gives the desired image quality is employed.

Abstract: Noise reduction is performed on the basis of characteristics of an image in a detection range. A noise reduction block 4′ performs a second-order differentiation process and a symmetry process to decide adjacent pixels with which noise reduction is preformed for an attention pixel. With the pixel level of the attention pixel in the detection range and the pixel levels of adjacent pixels used for noise reduction, an arithmetic mean processing section 16 calculates a mean value. A median filter 17 selects a median value. With the number of pixels used for noise reduction, it is determined whether the image in the detection range contains a flat portion, a ramp portion, or an edge. The mean value and the median value are weight-added with a weighted coefficient that are changed on the basis of characteristics of the image. The result is substituted for the level of the attention pixel. When the attention pixel is an isolated point, an all-pixel median filter section 31 selects a medium value of the levels of all the pixels in the detection range including the attention pixel and substitutes the median value for the level of the attention pixel.
