Abstract: Audio capture based on logarithmic conversion. At least some of the illustrative embodiments are methods including capturing audio represented by an electrical signal, the electrical signal having both positive voltage portions and negative voltage portions. In some cases, the capture is by: performing logarithmic analog-to-digital conversion on the positive voltage portions to create a first plurality of digital values; and performing logarithmic analog-to-digital conversion on the negative voltage portions to create a second plurality of digital values; and storing representations of the first and second plurality of digital values to a storage medium.

Abstract: Image capture based on logarithmic conversion. At least some of the illustrative embodiments are methods including capturing an image by: reading a plurality of analog signals from an array of light sensitive elements; performing logarithmic analog-to-digital conversion on the plurality of analog signals which creates a corresponding plurality of digital values; calculating a dynamic range of the image, the calculating by a processor executing a program; adjusting at least one of a brightness and contrast of the image based on the dynamic range; further adjusting at least one of the brightness and contrast by a user by way of an interface device; and storing representations of the plurality of digital values to a storage medium wherein the representations of the digital values include the image brightness and contrast adjustments.
