Claim Text:
1. An A/D converter comprising: a comparison section that compares a reference voltage with an input voltage, the reference voltage having a ramp waveform whose voltage value varies with time; a storage section that holds a count value in a predetermined count pattern, based on an output signal from the comparison section; a conversion section that converts the count value held by the storage section into binary data; and a supply section that supplies a pulse signal corresponding to the binary data obtained by conversion in the conversion section to a first counter, wherein the storage section supplies, to a second counter, a most significant bit signal representing a most significant bit of the count value in the count pattern until the output signal from the comparison section is reversed, and holds lower bits that are lower than the most significant bit of the count value in the count pattern when the output signal from the comparison section is reversed.
