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 for sharpening gastrointestinal (GI) images are disclosed. A target distance between the target region and the imaging apparatus is determined for a target region in the regular image. One or more filter parameters of a de-blurring filter are selected from stored filter parameters according to the target distance. A processed target region is generated by applying the de-blurring filter to the target region to improve sharpness of the target region. A method for characterizing an imaging apparatus is also disclosed. The imaging apparatus is placed under a controlled environment. Test pictures for one or more test patterns are captured at multiple test distances in a range including a focus distance using the imaging apparatus. One or more parameters associated a target point spread function are determined from each test picture for characterizing image formation of the imaging apparatus at the selected distance.

摘要： A method of automatic allocation of processing power and system resource for an image viewing and processing application is disclosed. The usage of a processing unit or system resources consumed by other computing-processes on the computer is determined. The usage required by the image viewing and processing application is determined. Then, based on the usage consumed by other computing-processes and the usage required by the image viewing and processing application, the adequacy of the processing unit or system resources for executing the image viewing and processing application is assessed. If the adequacy of the processing unit or system resources for executing the image viewing and processing application is not satisfied, the usage of the processing unit or system resources consumed by other computing-processes associated with other applications is displayed. Also, options to select one or more other applications for termination via a user interface are displayed. The selected applications selected are terminated to reduce the usage of the processing unit or system resources.

摘要： A method for determining an object's size based on calibration data is disclosed. The calibration data is measured by capturing images with an image sensor and a lens module, having at least one objective, of the capsule camera at a plurality of object distances and/or back focal distances and deriving from the images characterizing a focus of each objective for at least one color plane. Images of lumen walls of gastrointestinal (GI) tract are captured using the capsule camera. Object distance for at least one region in the current image is estimated based on the camera calibration data and relative sharpness of the current image in at least two color planes. The size of the object is estimated based on the object distance estimated for one or more regions overlapping with an object image of the object and the size of the object image.

摘要： An integrated image sensor circuit with multiple power modes is disclosed. The integrated circuit comprises a pixel array, an analog block to process analog signal associated with the pixel array, where the analog block comprises an analog to digital convertor (ADC), and a first control circuit to enable/disable the analog block or to configure the analog block to a high/low-power mode depending on whether the pixel array is in a readout frame or in a reset frame with no active readout. The integrated image sensor circuit may further comprise a post-processing block and a second control circuit to enable/disable the post-processing block or to configure the post-processing block to the high-power mode or the low-power mode depending on whether the pixel array is in the readout frame or in the reset frame with no active readout.
