Abstract:
An image processing apparatus comprising storage means for storing pixel data arranged in a matrix manner to form screen data, whereinsaid pixel data represents a corresponding pixel with one set of bits per pixel,said screen data includes at least two sets of field data, each being subjected to a predetermined processing by each of a plurality of data blocks including a first number of said pixel data in n rows (n is an integer), said storage leans includesa plurality of banks, each storing at least said first number of said pixel data successively without a precharging operation while one row address is being designated,each of said banks including n.times.1 memory planes, (where 1 is an interger) each having an address space with identical addresses, andprecharging means for precharging each of said plurality of banks individually;said storage means stores said each of the plurality of data blocks belonging to one of said sets of field data in a bank different from a bank corresponding to another of said sets of field data and assigns an identical address to pixel data corresponding to n pixels adjacent in the column direction of said each data block,said precharging means precharges one of said plurality of banks while another of said plurality of banks is being subjected to a write operation.
