    摘要: An image sensor may include an array of image pixels formed in rows and columns. Each image pixel in the array may include a photodiode and multiple signal readout paths connected to the photodiode. Each readout path may include a separate floating diffusion node and source follower transistor. The number of signal readout paths simultaneously enabled during an image capture operation may be determined by the exposure level such that the pixel operates with either high or low conversion gain. Several such image pixels of like color in the pixel array may be connected via a shared photodiode interconnection line such that image signals from interconnected pixels may either be binned and read out on a single readout path or read out individual on separate readout paths.

    摘要: To solve the problem of conventional image sensing devices that require much time for reading pixel signals, an image sensing device according to an embodiment includes a first pixel unit coupled to a first vertical read line, a second pixel unit coupled to a second vertical read line and placed in the column of the first pixel unit, a first transfer switch provided at an end of the first read line, and a second transfer switch provided at an end of the second read line. When the first transfer switch is controlled to be closed and the second transfer switch is controlled to be conductive, the image sensing device performs a reset process of the vertical read line by a dark level signal output from the second pixel unit, and a conversion process of the dark level read from the first pixel unit, and the pixel signal into digital values.

    摘要: Disclosed is an imaging device and method capable of obtaining an image with exposure appropriate for each sample when a plurality of samples are collectively imaged. For performing imaging using an imaging device configured to divide an imaging area into a plurality of partial areas, to perform imaging for each partial area, a proper exposure time is calculated for each partial area based on an image signal, a positive integer multiple of the maximum value among the calculated proper exposure times is set as a total imaging time, an imaging frequency is set for each partial area using a value obtained by dividing the total imaging time by the calculated proper exposure time, imaging with the calculated proper exposure time of the partial area is successively and repeatedly performed by the set imaging frequency, and each image successively imaged is simply added or is added and averaged.
