  • Patent number: 8792033
    Abstract: An image pickup apparatus capable of ensuring a dynamic range suitable for an image shooting condition and capable of reducing noise. The image pickup apparatus includes an image sensing device having floating diffusion units that are provided corresponding to pixels and that convert electrical charges accumulated in the pixels into voltage signals, which are output as pixel signals from pixel amplifiers. At that time, according to an image shooting condition, at least parts of connection switches corresponding to the floating diffusion units are sequentially turned on or all the connection switches are turned off, whereby the connection switches are connected to or disconnected from connection lines to thereby change capacity components connected to pixel amplifiers. This contributes to dynamic range expansion or noise reduction.
