This invention is to decrease the sensor pitch, prevent saturation by external light, accurately determine skimming, simplify skimming determination, and prevent any difference in influence of the transfer efficiency between the ON and OFF states. For this purpose, a distance measuring apparatus includes a light projection section for projecting light to an object, a sensor array for receiving reflected light from the object, a first transfer section for transferring charges from the sensor array, and a ring-shaped second charge transfer section for integrating the charges from the first transfer section, wherein the first charge transfer section transfers charges in a light projection ON state and charges in a light projection OFF state at a timing, the transfer frequency of the second charge transfer section is twice that of the first charge transfer section, and the timing of the first charge transfer section has a phase different from that of the second charge transfer section.
