    Abstract: A method for detecting a capsule camera entering into or exiting the GI tract, includes (a) taking a first test image under the condition that an illumination system of the capsule camera is disabled; (b) taking a second test image under the same condition as the first test image; (c) comparing selected corresponding pixel values of the first test image and the second test image to determine if a significant change in pixel values has occurred; and (d) upon detecting the significant change in pixel values, determining if the capsule camera has entered or exited the GI tract, and performing operations appropriate to follow such determination. The appropriate operations performed after detecting the capsule camera's exit from the GI tract includes stopping further taking or storing of images and, optionally, activating an audio signal to indicate the capsule camera has exited the GI tract. The appropriate operations performed after detecting the capsule camera's entering into the GI tract includes entering into an imaging mode for a next section of the GI tract, which may be the esophagus.

    Abstract: A capsule camera includes a pixel cell array of pixel cells exposed to light from a field of view, an illuminating system that illuminates the field of view, a signal processor receiving and processing data from the pixel cell array, and a control module that causes the pixel cell array to be read out using an improved scanning method. The scanning method includes pre-charging the pixel cells in the pixel cell array, illuminating a field of view of the pixel cells for a predetermined exposure time, and reading out data and the pixel cells only after the illuminating of the field of view is completed.

    Abstract: A semiconductor memory device and an associated method suitable for use in specific applications with predictable memory access pattern, such as in a capsule camera. The memory device takes advantage of the memory access pattern to simplify address processing circuit to realize savings in power and silicon area. Because random access to the semiconductor device is not required, the interface from external to the semiconductor device is also simplified by eliminating at least the address port that is used to specify the memory locations accessed. The method is applicable not only to non-volatile memory technologies (e.g., flash memory), it is also applicable to volatile memory technologies, such as transient charge storage-based memory circuits (e.g., DRAMs) and metastable states-based memory circuits (e.g., SRAMs).

    Abstract: A swallowable capsule with a camera and a memory for imaging the colon (Figure 4). Standard semiconductor memory (426), or memories made of standard memories processes or processes modified from standard process by adopting comprehensible silicon planar technology process steps, is used. This is made possible by the use of an optimal type of image compression (424) that can be performed with limited processing power and limited memory or without requiring a full size frame buffer. Also, controls on the number of images taken are used in one embodiment.

    Abstract: A method for intraframe image compression of an image is combined with a method for reducing memory requirements for an interframß image compression The intraframe image compression may include dividing the image into blocks, selecting a block according to a predetermined sequence, and processing each selected block The selected block may be compressed by compressing a difference between the selected block and the reference block, where the difference may be offset by a predetermined value The difference is compressed after determining that an activity metric of the difference block exceeds a corresponding activity metric of the selected block The activity metric is calculated for a block by summing a difference between each pixel value within the block and an average of pixel values within the block
