Patent Images
1. A method for reduced transmission of an image stream captured in-vivo, the method comprising:
- performing processing in an autonomous in-vivo imaging device, the processing comprising;
determining similarity between captured image data and image data previously transmitted in a communication channel, by comparing sub-samples of image pixels from the captured image data and the image data previously transmitted;
determining a quality level of the communication channel; and
if the captured image data is substantially similar to the image data previously transmitted, and if the quality level of the communication channel is above a pre-defined threshold value, reducing transmission of the captured image data.

Abstract
An in-vivo device, system, and method are described where an in-vivo device may transmit an image stream to an external receiving device. Reducing the size of the image data necessary for transmission may conserve energy consumed by the in-vivo device during transmission. An image data comparator unit incorporated within the in-vivo device may compare a captured image to a previously transmitted image and transmit, for example, only captured images that are substantially dissimilar to a previously captured image.
