Dwight D. Poplin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7333145
    Abstract: A camera module comprising an image sensor array, a gain amplifier, an indicator set to indicate whether a first flash device or a second flash device is present, and a plurality of storage locations. The plurality of storage locations is configured to store an exposure time and a gain. The exposure time and the gain are associated with the first flash device in response to the indicator indicating the presence of the first flash device, and the exposure time and the gain are associated with the second flash device in response to the indicator indicating the presence of the second flash device. The image sensor array is configured to capture an image using the exposure time, and the gain amplifier is configured to perform processing on the image using the gain.

  • Patent number: 7071456
    Abstract: A camera module forms digital images and measures an ambient light level. A device such as a digital camera, a telephone, or a PDA containing the camera module can set lighting levels of I/O systems such as keypads or displays according to the ambient light level to thereby save power or optimize functionality of the I/O systems. A dedicated sensor in the camera module or one or more selected sensors in the imaging array of the camera module can measure the ambient light level.

  • Patent number: 5329260
    Abstract: A numerically-controlled modulated oscillator and modulation method which selectively provides frequency modulation, phase modulation or amplitude modulation with minimal circuitry. A numerically-controlled modulated oscillator is provided having a tuning register for receiving a center frequency parameter, an adder for receiving at one input the frequency parameter, a phase accumulator for receiving a phase increment number from the adder and producing a waveform phase number, a waveform memory for producing a waveform amplitude number in response to the phase number, and a digital-to-analog converter for producing an analog signal in response to the waveform amplitude number. Another input is provided to the adder from an angle modulation register which provides an angle modulation parameter. This parameter can perform either phase or frequency modulation.
