Systems, methods, and media for reconstructing a space-time volume from a coded image are provided. In accordance with some embodiments, systems for reconstructing a space-time volume from a coded image are provided, the systems comprising: an image sensor that outputs image data; and at least one processor that: causes a projection of the space-time volume to be captured in a single image of the image data in accordance with a coded shutter function; receives the image data; and performs a reconstruction process on the image data to provide a space-time volume corresponding to the image data.
IMAGING UNIT, IMAGING APPARATUS, AND COMPUTER READABLE MEDIUM STORING THEREON AN IMAGING CONTROL PROGRAM
When the amplification ratio is low and strong incident light causes a large charge, the signal retrieved from regions where the incident light is weak is also weak, but when the amplification ratio is high in regions where the incident light is weak, the signal retrieved from regions where the incident light is strong becomes saturated. Therefore, the dynamic range of the imaging unit is narrow. Provided is an imaging unit comprising an imaging section that includes a first group having one or more pixels and a second group having one or more pixels different from those of the first group; and a control section that, while a single charge accumulation is performed in the first group, causes pixel signals to be output by performing charge accumulation in the second group a number of times differing from a number of times charge accumulation is performed in the first group.

METHOD AND APPARATUS PROVIDING PIXEL ARRAY HAVING AUTOMATIC LIGHT CONTROL PIXELS AND IMAGE CAPTURE PIXELS
A pixel array uses two sets of pixels to provide accurate exposure control. One set of pixels provide continuous output signals for automatic light control (ALC) as the other set integrates and captures an image. ALC pixels allow monitoring of multiple pixels of an array to obtain sample data indicating the amount of light reaching the array, while allowing the other pixels to provide proper image data. A small percentage of the pixels in an array is replaced with ALC pixels and the array has two reset lines for each row; one line controls the reset for the image capture pixels while the other line controls the reset for the ALC pixels. In the columns, at least one extra control signal is used for the sampling of the reset level for the ALC pixels, which happens later than the sampling of the reset level for the image capture pixels.
