no. 1 Embodiment approach

[0032]First, the reception system of the first embodiment will be described. Next, the method of use of the receiving system of the first embodiment will be described first, and then the structure, function, etc. of the receiving system will be described.

[0033] FIG. 1 is a schematic diagram showing how the receiving system according to the first embodiment is used. As shown in FIG. 1 , a receiving system 1 according to the first embodiment is used to receive and process a wireless signal transmitted from a capsule endoscope 3 introduced into a subject 2 . Specifically, the receiving system 1 according to the first embodiment includes: a receiving device 4 that is used while being carried by the subject 2, and performs receiving processing on wireless signals received via the receiving antennas 7a to 7h; 4, and a simple image display device 5 that displays images captured by the capsule endoscope 3 and outputs data to an external monitor 6 based on the electrical signal out...

no. 2 Embodiment approach

[0063] Next, a receiving system according to the second embodiment will be described. In this receiving system in the second embodiment, a configuration is employed in which information transfer between the nonlinear output unit and the nonlinear input unit is performed by wireless communication.

[0064] FIG. 4 is a schematic block diagram showing the configuration of a receiving system according to the second embodiment. As shown in FIG. 4 , in the receiving system of the second embodiment, the receiving device 4 has the same configuration as that of the first embodiment, while the simple image display device 31 is configured to include a wireless transmitting unit 32 and a wireless receiving unit 33. Instead of the light emitting unit 21 and the light receiving unit 22 . Moreover, in the second embodiment, the simple image display device 31 is externally configured as a transmission unit 34 with the input terminal 10 and the wireless transmission unit 32 built in; A simpl...

no. 3 Embodiment approach

[0070] Next, a receiving system according to the third embodiment will be described. The simple image display device included in the receiving system according to the third embodiment has a structure in which a transmission unit including a non-linear output unit and a non-linear input unit can be separated from the main body of the simple image display device. A structure that can be electrically connected to an external monitor only when it is mounted on the main body of a simple image display device.

[0071] FIG. 5 is a schematic block diagram showing the configuration of a simple image display device 38 constituting the receiving system according to the third embodiment. In addition, in this third embodiment, since the configuration of the receiving device constituting the receiving system is the same as that in the first and second embodiments, illustration thereof is omitted.

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.

Description

technical field [0001] The present invention relates to a simple image display device capable of generating image data based on an electrical signal generated by a receiving device, displaying an image based on the generated image data, and outputting the above image data to an external device, and a device equipped with a simple image display device. A receiving system, wherein the receiving device receives a predetermined wireless signal while being carried by a subject. Background technique [0002] In the field of endoscopes in recent years, swallowing capsule endoscopes have been proposed. The capsule endoscope is provided with an imaging function and a wireless communication function. The capsule endoscope has the function of accompanying the peristalsis of internal organs such as the stomach and small intestine in the body cavity after being swallowed from the subject's mouth for observation (examination) and until it is naturally discharged. These internal organs a...
