Abstract

See full text

An imaging apparatus and an electronic device with reduced size are disclosed. In one example, an imaging apparatus includes pixel circuits, an AD converter, an encoding unit, a holding unit, and an output unit. The pixel circuits output an electric charge signal generated from incident light. The AD converter compares the electric charge signal with a reference signal for each of the pixel circuits, and outputs, as a conversion result, a code input signal at a time when a comparison result has been inverted. The encoding unit encodes the conversion result from the AD converter. The holding unit holds an encoding result. The output unit outputs the encoding result held by the holding unit. The pixel circuits are disposed in a first substrate. The AD converter is disposed in a second substrate that is stacked in a lower layer of the first substrate.
