摘要： A method of adaptively displaying images captured using a camera according to quality of image matching. The system utilizes the quality of image matching to guide whether to stitch underlying images or not. The quality of image matching is measured between two images to be matched. The image is declared as a high-confidence image or a low-confidence image according to the quality of image matching. The high-confidence images are stitched into one or more larger composite pictures and displayed on a display device. On the other hand, the low-confidence images are displayed as individual images without stitching.

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 earned 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.

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.
摘要翻译：胶囊相机包括从视场曝光于光的像素单元的像素单元阵列，照亮视场的照明系统，接收和处理来自像素单元阵列的数据的信号处理器，以及控制模块，像素单元阵列使用改进的扫描方法读出。扫描方法包括对像素单元阵列中的像素单元进行预充电，在预定的曝光时间内照亮像素单元的视野，并且仅在完成了视场的照明之后从像素单元读出数据。像素单元的预充电在视野被照亮之前的预定时间段内进行。像素的行可以在不同的时间预充电。每行中的像素单元的预充电和读出之间的时间间隔可以是基本相同的。在一个实例中，将像素单元阵列的读出扩展到基本上在捕获连续的图像数据帧之间的时间。结果，发射机可以以基本上落在FCC MISC频带下的允许传输带宽内的平均数据速率来发送处理后的图像数据。在一个实例中，每行像素单元在照明系统接通的整个持续时间内被曝光。可以在视场外部（例如，在像素单元或传感器阵列的外边缘处）提供一组像素单元，从视场外的该组像素读取的数据可用于补偿热量和系统噪声在数据范围内。

摘要： 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).

摘要： A method and apparatus of processing and displaying images captured using an in vivo capsule camera are disclosed. One or more overlapped areas between a target image and each image in a neighboring image group are determined, which comprises at least two neighboring images around the target image. Marked pixels in the target image are then determined, where a pixel in the target image is designated as a marked pixel if the pixel is within an overlapped area between the target image and at least one neighboring image. If the total number of the marked pixels in the target image exceeds a threshold and the number of the marked pixels associated with the overlapped area(s) between the target image and any image in the neighboring image group is below the threshold, the target image is excluded from a set of images to be displayed on a display device.
