摘要： A method for intraframe image compression of an image is combined with a method for reducing memory requirements for an interframe image compression. The intraframe image compression includes (a) dividing the image into blocks; (b) selecting a block according to a predetermined sequence; and (c) processing each selected block by: (1) identifying a reference block from previously processed blocks in the image according to an activity metric; and (2) using the reference block, compressing the 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. The activity metric depends on elements of a difference block, which is a block in which elements are each a difference between an element of the current image frame and a corresponding element of the reference frame. The activity metric is a function of the sum of (a) the sum over all rows of all differences between two successive consecutive elements of each row of the difference block; and (b) the sum over all columns of all differences between two consecutive elements of each column of the difference block. The reference block is identified by minimizing a cost function based on the activity metric and either a sum of absolute differences function or a sum of square differences function. The cost function may be a weighted sum of the activity metric and either a sum of absolute differences function or a sum of square differences function, or a weighted sum of the activity function and either a sum of absolute differences function or a sum of square differences function.

摘要： A capsule camera with on-board storage to archive the captured images in on-board non-volatile memory is disclosed. The capsule camera with on-board storage comprises multiple chips including a system processing chip and one or more non-volatile memory chips, where the system processing chip includes a compression module to compress images captured. If the multiple chips use individual chip packages and are disposed on respective printed circuit boards according to a conventional approach, it would require too much space to fit the multiple chips into the capsule camera housing. Accordingly, a capsule camera embodying the present invention is disclosed where the capsule camera integrates an image sensor, a light source, at least one system processing chip comprising compression module, one or more non-volatile memory chips and a battery into a housing, wherein the at least one system processing chip and said one or more non-volatile memory chips are disposed vertically in a multiple chip assembly.

摘要： Systems and methods are provided for environment change sensing corresponding to the capsule camera entering the colon from the small intestine. In the environment change sensing mode, the capsule camera is operated in a very low power mode by configuring the image sensor to use a small region of interest or a high sub-sampling ratio. Image data is processed to estimate the light level. The variation of light level is used to detect environment change corresponding to entering the colon from the small intestine. Alternatively, the motion metric for a current frame and a reference frame is evaluated. The characteristic of the motion metric is extracted and used to detect environment change. In another configuration, the system determines environment change based on a combination of the variation of light intensity and the characteristic of the motion metric. Upon the detection of capsule camera entrance into the colon from the small intestine, control signals are provided to the image sensor and the light source.

In one embodiment, such a camera system includes: (a) optical components that create multiple images in close physical proximity of each other (e.g., within a few millimeters or centimeters); and (b) a single sensor substrate (“chip”) containing multiple 2-dimensional pixel arrays that are aligned to capture these multiple images, so as to convert the multiple images into electrical signal. The pixel arrays can be manufactured using a CCD or a CMOS compatible process. For manufacturing reasons, such a chip is typically two centimeters or less on a side.

摘要： A method for transmitting data to a camera without requiring in the camera a conventional wireless transmission capability includes (a) in the camera's field of view, providing an object which forms an image on which the data is encoded; (b) capturing an image of the object using optics of the camera; and (c) recovering the data from the image of the object. The data is encoded by an optically detectable quantity (e.g., light intensity or color) or a pattern in one or more portions of the object. The data can be carried by the distribution of the optically detectable quantity within the image or its derivative. The field of view of the camera may be divided into multiple sub-areas to allow providing multiple data-bearing images. A sequence of such images may be used to increase the amount of data that can be transmitted in this manner. In addition, the time domain can be used to create one further dimension of data encoding. In addition, communication in the opposite direction may be provided using one or more lighting devices in the camera. One use is to provide a response (e.g., acknowledgement or non-acknowledgement to the data transmission based on the data recovered). The camera's response may be detected by one or more light detectors outside of the camera. Communication can be carried out using an interactive communication protocol. By providing multiple lighting devices in the camera and multiple light detectors in the outside, the system provides a parallel data bus, which may include a clock signal to govern timing on the bus. The data may be represented as quantized values.

摘要： 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 from the pixel cells only after the illuminating of the field of view is completed. The pre-charging of the pixel cells is carried out over a predetermined time period prior to the field of view being illuminated. The rows of the pixel may be precharged at different times. The time interval between the precharging and the reading out of the pixel cells in each row may be substantially the same. In one instance, the reading out of the pixel cell array is spread out to substantially the time between capturing successive frames of image data. As a result, a transmitter may transmit the processed image data at an average data rate falling substantially within the allowable bandwidth of transmission under the FCC MISC band. In one instance, each row of pixel cells is exposed for the entire duration the illumination system is turned on. A group of pixel cells may be provided outside of the field of view (e.g., at the outer edge of the pixel cell or sensor array. The data that is read from this group of pixels outside the field of view may be used to compensate for thermal and system noise in the data within the field of view.
