Abstract: An image sensing apparatus includes a pixel array, a first color filter, a second color filter, and a light shielding portion. The amount of electric charges generated in a first pixel after light of a first wavelength enters the first pixel is larger than that of electric charges generated in a second pixel after light of a second wavelength enters the second pixel. The light shielding portion defines the aperture regions of the first and second pixels so as to set the aperture area of the first pixel larger than that of the second pixel.

Abstract: An apparatus includes a pixel region having disposed therein in a matrix form a plurality of conversion components, an amplifier transistor which amplifies a signal from the plurality of conversion components, a reset transistor which sets the potential of an input portion of the amplifier transistor to a reset potential, and a select transistor which is connected in series to the amplifier transistor and selects and reads the amplified signal, and well contact regions which are provided within the pixel region. Each of the well contact regions is neighboring to a drain region of the reset transistor, and the drain region of the reset transistor has a lower impurity concentration than the impurity concentration in the source and drain regions of the select transistor.

Abstract: An imaging system includes an image sensor and a mechanical shutter which controls the termination of exposure of the image sensor. The image sensor includes a pixel array in which a plurality of pixels are arrayed in a matrix, and a vertical scanning unit which scans the pixel array for each row. The vertical scanning unit parallelly executes some of the reset operations of pixels on at least two adjacent rows of the pixel array. The charge accumulation operation of pixels starts upon completion of the reset operation and terminates in response to light shielding by the mechanical shutter.
