Pixels output a first signal based on signal charge of a part of photoelectric conversion units of multiple photoelectric conversion units, and a second signal based on signal charge of multiple photoelectric conversion units. An imaging apparatus outputs signals based on the first signals and signals based on the second signals by reducing the number of signals based on the first signals as compared to the number of signals based on the second signals.

Imaging apparatus, and imaging system having a plurality of pixels for outputting a signal based on a generated signal charge

A semiconductor apparatus includes a stack of a first chip having a plurality of pixel circuits arranged in a matrix form and a second chip having a plurality of electric circuit arranged in a matrix form. A wiring path between a semiconductor element configuring the pixel circuit and a semiconductor element configuring the electric circuit or a positional relationship between a semiconductor element configuring the pixel circuit and a semiconductor element configuring the electric circuit is differentiated among the electric circuits.

Semiconductor apparatus and equipment

In a line sensor including color filters that are periodically disposed in a light-receiving-element row, a problem called a 'mixture of colors' occurs. A 'mixture of colors' occurs when light that has been transmitted through a color filter differing from a color filter corresponding to a light receiving element is incident upon the light receiving element. In a CMOS sensorincluding a light-receiving-element row in which a plurality of photodiodesare disposed side by side in a main scanning direction and a plurality of color filtersthat are disposed in correspondence with the plurality of photodiodes, the center of each color filteris displaced in a direction of the center of the light-receiving-element row from the center of the photodiodecorresponding to the color filter.
