A method includes receiving statistical image data for a set of image data. The statistical image data includes composite intensity metrics for each of a plurality of color channels for each of a plurality of cells of a subsampling grid. A histogram is generated for each of the color channels based on the composite intensity metrics. A gain for each of the color channels is determined based on the histograms. The gains for each of the color channels are applied to the set of image data. The set of image data is stored after applying the gains to generate an image data file.

Automatic white balance using histograms from subsampled image

A method in a mobile wireless communication device capable of receiving a paging message transmitted in a series of bursts over successive time frames including receiving () not more than one burst of an incoming paging message, determining () whether the incoming paging message corresponds to a known paging message, and () reducing power consumption of radio circuits of the mobile wireless communication device during time frames when other bursts would be received if the incoming paging message corresponds to the known paging message. If the incoming data does not correspond to the known data, additional burst are received and decoded.

A method and apparatus for converting the sampling rate of digital signals including a decimating comprising a low pass filter () and a downsampler (), wherein the input signal is decimated a number of times based on a ratio of an input sampling rate to an output sampling rate. The exemplary apparatus also includes an upsampler () and another decimator () wherein the signal is upsampled after decimating if a ratio of the input sampling rate to an output sampling rate is not a power of an integer number.

A system and method for efficiently upsampling and filtering a signal is provided. The system includes a controllerand an upsamplercapable of upsampling a digitized signal. The upsamplerconverts a digitized signal having a first sampled frequency into a digitized signal having a second sampled frequency by inserting, for example, at least one zero between the samples of the digitized signal. A plurality of filtersis coupled to the upsampler. These filters, which may be band-pass filters, would be suitable for front end encoding in audio-based applications. The controlleradjusts at least one output of the plurality of the filters to zero, either by deactivation or forcing the filter to zero, based upon a predetermined characteristic of the digitized signal. One example of a predetermined characteristic is a maximum frequency of interest.

System and method for efficient upsampled signal processing

In a cellular telephone, a method of reducing background noise of an audio signal resulting from a received signal. Each digital sample of the audio signal is used to calculate an average energy of the audio signal over a number of samples. When the average energy is less than a threshold, a gain factor is calculated using the average energy and the threshold. The amplitude of the audio sample is then adjusted according to the gain factor.
