Method And Apparatus For Compressive Imaging Device Having Startle Reflex
First Claim
1. A method for power management in an imaging device having a low sampling rate and a high sampling rate, the method comprising the steps of:
- collecting a training set of samples while operating said imaging device at said low sampling rate;
computing an empirical probability distribution of said training set of samples;
collecting a testing set of samples while operating said imaging device at said low sampling rate;
computing an empirical probability distribution of said testing set of samples;
computing an empirical test statistic; and
capturing an image at said high sampling rate in response to said computed empirical test statistic exceeding a threshold.

Abstract
A method and apparatus for new digital image/video camera that directly acquires random projections of the incident light field without first collecting the pixels/voxels and has a startle reflex. The startle reflex is achieved by collecting a training set of samples while operating the imaging device at the low sampling rate, computing an empirical probability distribution of the training set of samples, collecting a testing set of samples while operating the imaging device at the low sampling rate, computing an empirical probability distribution of the testing set of samples, computing an empirical entropy test statistic, and capturing an image at the high sampling rate in response to the computed empirical entropy statistic exceeding a threshold.
