Solid-state pickup apparatus, its driving method and camera system

摘要

There is used an XY address type solid-state image pickup element (for example, a MOS type image sensor) in which two rows and two columns are made a unit, and color filters having a color coding of repetition of the unit (repetition of two verticals (two horizontals) are arranged, and when a thinning-out read mode is specified, a clock frequency of a system is changed to 1/9, and on the basis of the changed clock frequency, a pixel is selected every three pixels in both a row direction and a column direction to successively read out a pixel signal.

主权项

1. An imaging device, comprising:
a plurality of pixels arranged in a matrix;a plurality of color filters individually formed at respective pixels; and
a driving unit configured to select the pixels and read out pixel signals based on a read mode,whereinthe driving unit is configured to read out pixel signals of selected pixels in a thinning-out read mode such that the selected pixels are read out based on a predetermined color pattern and non-selected pixels are not read out,a pixel unit is made of pixels of two rows and two columns, and
the driving unit is configured to read out an addition signal of lower left pixels corresponding to the units, an addition signal of lower right pixels, an addition signal of upper left pixels, and an addition signal of upper right pixels.
