Abstract
Provided is an imaging device comprising means for binning by adding up and reading out pixel signals from a plurality of pixels arranged in a first direction and a second direction of a pixel arrangement of an imaging element. The imaging device is provided with first means for changing a combination pattern of added pixel signals on a per-frame basis, and second means for generating image signals for one frame based on added signals from plural frames having different combination patterns.
Claims8
An imaging device comprising a signal readout unit which bins by adding up and reading out pixel signals from a plurality of pixels arranged in a first direction and a second direction of a pixel arrangement of an imaging element, when signals are read out from the imaging element;
- a pattern changing unit wherein there are n different combination patterns of pixel signals to be added by the signal readout unit (n is an integer of not less than 2), which changes the combination patterns of pixel signals to be added by the signal readout unit on a per-frame basis such that each different combination pattern is applied to a sequence of n frames to be read out from the imaging element;
- and
- a video signal generating unit which generates image signals for one frame based on signals from plural frames comprising a sequence of n frames or (n+1) frames to be read out from the imaging element by the signal readout unit.
A video signal generating method employed in an imaging device comprising a signal readout step which bins by adding up and reading out pixel signals from a plurality of pixels arranged in a first direction and a second direction of a pixel arrangement of an imaging element, when signals are read out from the imaging element;
- a pattern changing step wherein there are n different combination patterns of pixel signals to be added by the signal readout step (n is an integer of not less than 2), which changes the combination patterns of pixel signals to be added by the signal readout step on a per-frame basis such that each different combination pattern is applied to a sequence of n frames to be read out from the imaging element;
- and
- a video signal generating step which generates image signals for one frame based on signals from plural frames comprising a sequence of n frames or (n+1) frames to be read out from the imaging element by the signal readout step.
An imaging device comprising
- a signal readout unit which skips pixel signals of one part of all pixels in a pixel arrangement of an imaging element and reads out pixel signals of the other pixels, the signal readout unit skipping both pixel signals in a first and a second directions of the pixel arrangement;
- a pattern changing unit wherein there are n different skipping patterns of pixel signals by the signal readout unit (n is an integer of not less than 2), which changes the skipping patterns of pixel signals by the signal readout unit on a per-frame basis such that each different skipping pattern is applied to a sequence of n frames to be read out from the imaging element;
- and
- a video signal generating unit which generates image signals for one frame based on signals from plural frames comprising a sequence of n frames or (n+1) frames to be read out from the imaging element by the signal readout unit.
