- W4387300003 abstract "This work presents an imager architecture capable of forming frames with varying exposure time and focus from event-based imager data, in post processing. Conventional photography dictates that once a frame has been captured the information associated with the frame is controlled by the aperture/depth-of-field, the exposure time, and the ISO. The advent of technologies such as integral photography and plenoptic cameras made it possible to change the depth-of-field and plane-of-focus in post-processing. Recently, the concept of the digital coded exposure for event-based imagery was introduced, which allowed the formation of frames from event-data that respected a per-pixel, digitally specified, exposure-vs-time function. The digitally coded exposure allowed the formation of frames with different exposure time characteristics, on a per-pixel basis, in post-processing, from event-based imager data. In this work we present an imager architecture that leverages both plenoptic imager principles, and digital coded exposure principles, to result in an imager that allows regeneration of frames in post processing, in such a way that modification of two sides of the standard exposure triangle is possible. The proposed architecture could potentially also work with alternative imaging modalities such as a photon counting imager." @default.
