Abstract
Conventional semiconductor devices disadvantageously failed to sufficiently enlarge a dynamic range. A semiconductor device according to an embodiment includes a plurality of registerstothat sets a gradient of a ramp signal. In the semiconductor device, the values in the registerstothat are reflected in the gradient of the ramp signal are switched at predetermined timings, whereby a ramp signal with a gradient that changes at the predetermined timings is generated, and an analog-to-digital converter uses the ramp signal to convert pixel signals acquired from a pixel area into digital values.
