The signal processing system according to claim 1, wherein the control section controls the setting value changing section based on the control command to initialize the setting value. 3. The signal processing system according to claim 1, wherein the signal processing unit includes an identification display section for enabling a user to identify a setting item of which setting value is to be changed, andthe control section controls a manner of indication of the identification display section based on the control command. 4. The signal processing system according to claim 3, wherein the manner of indication of the identification display section is a manner of light emission of a light emission section provided near a setting change switch which is operable to control the setting value changing section. 5. The signal processing system according to claim 4, wherein the light emission section is an LED and the manner of light emission is one of turning on, blinking, and turning off the LED. 6. The signal processing system according to claim 1, wherein the control command when the log data has exceeded a predetermined threshold value is an initialization command for initializing the setting value related to the setting data. 7. The signal processing system according to claim 1, wherein the control section controls displaying of control information which is based on the control command on the display section. 8. The signal processing system according to claim 1, further comprising: a power-off moment setting value storing section for storing the setting value when power is turned off; anda comparing section for comparing the setting value when power is turned on and the setting value stored in the power-off moment setting value storing section,wherein the log recording section records a comparison result of the comparing section. 9. The signal processing system according to claim 8, wherein the data sending section sends the comparison result recorded in the log recording section to the external instrument via the network. 10. The signal processing system according to claim 1, wherein the log recording section records a last setting value which was set when recording the log data as a current value, records a last setting value recorded before recording the log data as a previous value, and generates bit data that indicates presence or absence of a difference between the current value and the previous value based on a result of comparison between the current value and the previous value and writes the generated bit data into the log data. 11. A signal processing system comprising, an endoscope for picking up an image of an inner body cavity by an image-pickup section; a light source for supplying illumination light to the endoscope; anda signal processing device including a plurality of signal processing sections for processing image-pickup signals from the endoscope,wherein the signal processing device includes: a control section for controlling, based on a setting value, operation of at least one of an internal circuit of the endoscope, an internal circuit of the signal processing section, and an internal circuit of the light source;a setting value changing section for changing the setting value;a log recording section for recording change history of the setting value as log data;a data sending section for sending the log data to an external instrument via a network; anda command receiving section for receiving a control command which is based on the log data from the external instrument via the network, andwherein the control section controls the setting value changing section based on the control command received from the external instrument. 12. The signal processing system according to claim 11, wherein the signal processing device processes image-pickup signals picked up with a plurality of different observation lights, based on the setting value for each of the plurality of different observation lights, which is changed by the setting value changing section. 13. The signal processing system according to claim 11, wherein the log recording section records a last setting value which was set when recording the log data as a current value, records a last setting value recorded before recording the log data as a previous value, and generates bit data that indicates presence or absence of a difference between the current value and the previous value based on a result of comparison between the current value and the previous value and writes the generated bit data into the log data.
