PURPOSE:To smoothly perform processing of picture effects in the case of transferring image data in the still picture reproducing device. CONSTITUTION:A control host processor (master) 2, image processing processor (slave) 5, picture effect processor (slave) 6 and I/O controller (sub slave) 12 are connected to a main bus 1 so that the I/O control 12 can become the bus mater of the main bus 1, after non-compressed image data inputted from the I/O controller 12 are transferred to a transfer buffer memory 8 by an image extension co-processor 7 connected to an I/O, a control command for transferring the image data in the transfer buffer memory 8 to the designated area of an image memory 4 is issued by the I/O controller 12 as a bus master and at the time of transferring the image data, the control command is issued to the picture effect processor 6 at any arbitrary time by the control host processor 2. |
