Time Domain Continuous Imaging (TDCI) is a new model for photography that allows exposure timing to be freely manipulated after capture. This is done by creating, and operating on, a continuous waveform representation of how the value of each pixel changes over time. However, at this
writing, there are no sensors that directly implement TDCI capture. The FourSee multi-camera prototype enables temporally-skewed exposures to be captured using the four component cameras and then later post-processed to create a TDCI representation, but the postprocessing is awkward and requires
upload of image data to a separate computer. In contrast, this paper reports on a method whereby a single, conventional, Canon PowerShot camera can be used as a stand-alone TDCI platform. The camera programming is enhanced by custom code which is loaded into the camera using the Canon Hack
Development Kit (CHDK). Thus, using code that should be portable to most camera models supported by CHDK, an inexpensive Canon PowerShot camera is able to internally capture and manipulate TDCI streams in the new .tik (Temporal Image Kontainer) file format.

For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.
Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
