An audio limiting circuit capable of satisfying frequency dependent limits and time domain constraints, is disclosed. In one illustrative embodiment, an input node receives an unattenuated input signal and a system modeling filter predicts the amount, if any, by which the sound pressure level that would be generated by an acoustic transducer in response to the unattenuated input signal, would exceed one or more predetermined limits. In that embodiment, an energy detector separates the excess predicted sound pressure level into one or more frequency bands and calculates the average acoustic energy associated with each band. A gain logic block determines an attenuation factor based on whether one or more of the predetermined limits has been exceeded and the attenuation factor values are smoothed to minimize abrupt changes to the unattenuated input signal. A delay buffer delays the unattenuated input signal values. Finally, in the embodiment described here, the smoothed attenuation factor values are synchronized with and applied to the delayed input signal values and the resulting attenuated signal is transmitted to an output node and ultimately to one or more acoustic transducers.

The present invention accurately reproduces an image pattern by referring to neighboring pixels upon determining the threshold value of a target pixel so that a delay in dot generation can be prevented while emphasizing an image transition portion so that both graininess and sharpness are improved in the image. To this end, a neighboring pixel density difference detection part obtains an absolute value of the density difference between a target pixel and its neighboring pixels and selects the density of a neighboring pixel with a large absolute value as a reference pixel density. Further, a threshold value quantity determination part determines a threshold value corresponding to the density selected by the neighboring pixel density difference detection part. Then, a quantization part outputs an output value based on a comparison between the threshold value and a corrected value obtained by adding a pre-calculated error value of neighboring pixels to an input value.
