The parameter setting module 43 is connected to the image recognition module 42 and the equalizer EQ signal, and the parameter setting module 43 is configured to generate a parameter setting command according to the correction processing parameter obtained by the image recognition module 42 to control the equalizer EQ adjustment. Set the gain value of the sound at different frequencies. For example, the different processing digits of the correction processing parameter from left to right respectively represent values to be adjusted by the gain values at different frequencies. Therefore, if the corresponding correction processing parameter is “0000011650”, the parameter generated according to the parameter is generated. The setting command can be used to set the gain value of 1 decibel (dB) at 1KHz and 2 KHz, the gain value of 6 dB at 4KHz, and the gain value of 5 dB at 8KHz.

After the parameter setting module 30 completes the adjustment operation, the gain value in each mode of the equalizer EQ is synchronously set to a new gain value, as in the above example, that is, the gain value of the sound at a frequency of 4 kHz in each mode. The gain value is increased by 6dB compared with the original (as shown in Figure 6 and Figure 7), and the gain values at the other different frequencies are also adjusted.
