The medical manipulator according to claim 1, wherein: when two of the plurality of input units are defined as a first input unit and a second input unit, the first input unit and the second input unit include a common input mechanism, andtwo of the plurality of process conditions which correspond to the first input unit and the second input unit include a type of a function exhibited in the operating unit by an input to the common input mechanism. 10. A method of controlling a medical manipulator including a plurality of input units selectively used by an operator and a plurality of slave arms, each of the plurality of slave units corresponding to one of the plurality of input units, of the input units is used at a time by the operator, each of a plurality of process conditions corresponding to one of the plurality of input units being prepared in advance so that the process conditions are different from each other, the method comprising: capturing image data of one of the plurality of input units which is currently used by the operator;detecting the one of the plurality of input units which is currently used by the operator as a currently used input unit based on the captured image data;generating a manipulation signal by processing an input with respect to the currently used input unit based on one of the plurality of process conditions which corresponds to the currently used input unit; andoperating one of the slave arms which corresponds to the currently used input unit by using the manipulation signal. 11. A medical manipulator comprising: a manipulation unit configured to have a first input unit and a second input unit that are exchangeable and manipulated by an operator;an image sensor configured to capture an image of at least one of the first input unit and the second input unit;a processor comprising hardware, the processor being configured to: discriminate between the first input unit and the second input unit, recognize the first input unit and the second input unit, and acquire coordinates of the first input unit and the second input unit in a visual field of the capturing unit, from an image captured by the image sensor;output the coordinates as coordinate information; andperform a process based on a predetermined process condition using the coordinate information to generate a manipulation signal; andan operating unit mounted on a treatment tool and configured to be operated by the manipulation signal,wherein the process condition corresponding to the first input unit and the process condition corresponding to the second input unit differ from each other, andthe processor is further configured to generate the manipulation signal based on the process condition corresponding to the recognized one of the first and second input units. 12. The medical manipulator according to claim 11, wherein the first input unit has a first marker having a visual feature specific to the first input unit,the second input unit has a second marker specific to the second input unit, the second marker being capable of being visually discriminated from the first marker, andthe processor discriminates between the first marker and the second marker, recognizes the first marker and the second marker, and acquires coordinates of the first marker and the second marker in the visual field of the image sensor, from the image captured by the image sensor. 13. The medical manipulator according to claim 11, wherein the process condition includes a setting aspect of a coordinate system in the input unit. 14. The medical manipulator according to claim 11, wherein the process condition includes an origin position of a coordinate system in the input unit. 15.
