An image processing apparatus comprising: a plurality of graphics processors for processing image processing in parallel, wherein each of said plurality of graphics processors comprises a load calculator for calculating a load of processing placed on its own geometry engine on the basis of inputted graphics commands and outputting a high-load signal indicating that the load is excessive if the load exceeds a present specified threshold value, and wherein each of said plurality of graphics processors comprising: an input memory for temporarily holding the graphics commands distributed from said command distributor: a computing unit for processing image processing for the graphics command inputted from said input memory; a first decoder for determining kinds of the graphics commands used for an operation processed by the graphics processor and notifying said load calculator of the determining kinds; and a second decoder for determining kinds of entered graphics commands and notifying said load calculator of the determining kinds, wherein said load calculator calculates the load placed on the graphics processor on the basis of notification from said first and second decoders. 4. The image processing apparatus according to claim 3, said load calculator comprising: a load data table for recording a load value corresponding to each of the graphics commands: and a processor for calculating the load calculation, wherein said processor receives notification from said first and second decoders, and executes load calculation by referring to the load data table. 5. The image processing apparatus according to claim 4, said load calculator further comprising: a threshold value memory for storing a threshold value, wherein said processor asserts the high-load signal if a load value obtained by the load calculation exceeds the threshold value, and deasserts the high-load signal if the calculated load value is equal to the threshold value, alternatively lower. 6. The image processing apparatus according to claim 5, said load calculator further comprising: a buffer for holding the calculated load value, wherein said processor receives notification from said first and second decoders, obtains a load value corresponding to a notified kind of a graphics command by referring to the load data table, subtracts the obtained load value from the load value held in the buffer if the notification is from the first decoder, adds the obtained load value to the load value held in the buffer if the notification is from the second decoder, and then updates the value in the buffer. 7. The image processing apparatus according to claim 4, said load calculator further comprising: a first threshold value memory for storing a preset first threshold value; and a second threshold value memory for storing a preset second threshold value, wherein said processor asserts the high-load signal if a load value calculated by keeping the high-load signal in a deasserted state exceeds the first threshold value, and deasserts the high-load signal if the load value calculated by keeping the high-load signal in an asserted state is equal to the second threshold value, alternatively lower. 8. The image processing apparatus according to claim 4, said load calculator further comprising: a threshold value memory for storing a preset threshold value, and a timer for counting specified time, wherein said processor asserts the high-load signal and said timer starts counting time if a load value obtained by calculation exceeds the threshold value, and said processor deasserts the high-load signal after fixed time is counted by said timer. 9. The image processing apparatus according to claim 4, said load calculator further comprising: a temporary memory for te
