摘要： A method and digital camera module is provided for taking a digital picture of an image. The digital camera module includes a plurality of light sensitive pixel elements, a first memory buffer, a second memory buffer and a controller. The controller is coupled to the plurality of light sensitive pixel elements and the first and second memory buffers and records a first plurality of pixel values representing an image by activating the plurality of light sensitive pixel elements in a first predetermined manner and stores the first plurality of pixel values in the first buffer. The controller then records a second plurality of pixel values representing the image by activating the plurality of light sensitive pixel elements in a second predetermined manner and stores the second plurality of pixel values in the second buffer. The controller further processes the first and second plurality of pixel values in a compressed domain to generate a third plurality of pixel values representative of the image.

摘要： A light sensing circuit (400) and image sensor array includes at least one light sensing element (402), such as a photodiode, and at least one ferroelectric element (404), such as a CMOS ferroelectric gate field effect transistor (FET), that is operatively coupled to the light sensing element to form a photo cell. The ferroelectric element provides charge storage as a non-volatile analog memory element. As such, a type of photo cell serves as a ferroelectric memory that can store the charge from the light sensing element and be programmed to provide electronic shutter operation.

摘要： A circuit for use in an image sensor as well as an image sensing system using the circuit are set forth. The circuit comprises a floating gate semiconductor device having a floating gate, a control gate, a drain and a source. The circuit also employs a photosensitive semiconductor device that is positioned for exposure to electromagnetic radiation from an image. A pixel control circuit is connected to these components to direct the floating gate semiconductor device and the photosensitive semiconductor device to a plurality of controlled modes. The controlled modes may include an erase mode and an exposure mode. In the erase mode, at least a portion of an electric charge is removed from the floating gate to place the floating gate semiconductor device in an initialized state. In the exposure mode, the floating gate is charged at least partially in response to a voltage at a terminal of the photosensitive semiconductor device. The voltage at the terminal of the photosensitive semiconductor device corresponds to exposure of the photosensitive semiconductor device to the electromagnetic radiation from the image. The pixel control circuit may also direct the floating gate semiconductor device and the photosensitive semiconductor device to further modes including a read mode and a data retention mode. In the read mode, current flow between the source and drain of the floating gate semiconductor device is detected as an indicator of the charge on the floating gate. In the data retention mode, the charge on the floating gate of the floating gate semiconductor device that was acquired during the exposure mode is maintained notwithstanding further exposure of the photosensitive semiconductor device to the electromagnetic radiation from the image. The circuit, and one or more peripheral support circuits, may be implemented in a monolithic substrate using, for example, conventional CMOS manufacturing processes.

摘要： A method for receiving a broadcast message in a wireless communication device is disclosed. The device receives a broadcast message that has associated therewith a unique message grouping identifier and determines whether the unique message grouping identifier of the received message is equal to a unique message grouping identifier of a previously received message. The device ignores the received broadcast message when the unique message grouping identifier of the received message is equal to the unique message grouping identifier of the previously received message and in some implementations enters sleep mode.
