Abstract: To realize a simplified image display apparatus that prevents electrical connection between an external monitor and a receiving device when an electric signal generated by the receiving device is transmitted to the external monitor. The simplified image display apparatus includes a photocoupler 23 formed of a light emitting unit 21 electrically connected only to an input terminal 10 and a light receiving unit 22 that receives light output from the light emitting unit 21, a demodulator 24 that demodulates a received radio signal, a switching unit 25 that outputs either one of electric signals from the photocoupler 23 and from the demodulator 24, and a data generator 26 that applies predetermined signal processing to the electric signal input from the switching unit 25 to generate image data, and outputs the image data to a display unit 9 and an output terminal 11.

Abstract: Each of detecting circuits 36a, 36d, 36f, and 36h detects a key signal such as a horizontal synchronization signal, a vertical synchronization signal, a capsule ID, a WB coefficient, and error information, i.e., a key signal superposed on RF signals received by an RF receiving unit 33. Each of determining units 36b, 36c, 36e, 36g, and 36i determines whether an image is valid or invalid based on the result of detection. A recording deciding unit 36k decides whether to record the image information in a storage unit 35 or not based on the result of determination. Thus, a receiving apparatus 3 can stop recording the image information received when a trouble occurs, thereby preventing defective images from mixing into the recorded image information, and preventing a recorded image size from becoming large, whereby necessary images can be recorded within a predetermined examination time.

Abstract: A fast accurate multi-channel frequency dependent scheme for analyzing noise in a signal processing system is described herein. Noise is decomposed within each channel into frequency bands and sub-band noise is propagated. To avoid the computational complexity of a convolution, traditional methods either assume the noise to be white, at any point in the signal processing pipeline, or they just ignore spatial operations. By assuming the noise to be white within each frequency band, it is possible to propagate any type of noise (white, colored, Gaussian, non-Gaussian and others) across a spatial transformation in a very fast and accurate manner. To demonstrate the efficacy of this technique, noise propagation is considered across various spatial operations in an image processing pipeline. Furthermore, the computational complexity is a very small fraction of the computational cost of propagating an image through a signal processing system.

Abstract: An object of the present invention is to enable clearly identifying whether a body-cavity image displayed on a display unit is based on data which is directly received by a viewer itself, or whether the body-cavity image displayed on the display unit is based on data received by another receiving device. An identification notifying unit presents different identification modes such as a capsule mark and a cable mark 41 which are sensory recognizable between the case where a body-cavity image based on body-cavity image data which a first receiving unit has received directly from a capsule endoscope is displayed, and the case where a body-cavity image 40 based on body-cavity image data which a second receiving unit has received via another receiving device is displayed. Thus, it is possible to clearly identify which receiver has received the body-cavity image data based on which the body-cavity image is displayed.

Abstract: A receiving apparatus that can prevent beforehand that a portable recording medium is erroneously ejected during examination, and can prevent body cavity image data from being lost and the portable recording medium from being damaged is provided. When an ejection operation of the portable recording medium is detected (step S103: Yes) during a recording operation (step S101: Yes), a warning unit is operated before the portable recording medium is ejected to give a warning to a user so as not to perform the ejection operation (step S105). Accordingly, the portable recording medium can be prevented beforehand from being ejected during the recording operation, thereby preventing body cavity image data from being lost and the portable recording medium from being damaged.

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.

Thus, unnecessary power consumption is prevented and the completion of the examination by the body insertable device is recognized.
