An image processing device for controlling a display device to display a plurality of unit images making up a moving image at predetermined intervals, the image processing device comprising:
- 4×N (N:
- an arbitrary integer) quadrant memories, each associated with one of 4×N types of quadrant images into which the unit image is divided;
- a separation section adapted to separate a moving image signal for the moving image into unit image signals, each of which is associated with one of the 4×N unit images to be displayed successively in time;
- a memory output control section adapted to sequentially delay the output start timing of each of the 4×N unit image signals, separated by the separation section, to the quadrant memory by the predetermined interval as output control, the memory output control section also adapted to sequentially output quadrant image signals, each of which is associated with one of the 4×N types of quadrant images, in a predetermined order over a period equal to 4×N times the predetermined interval;
- an assignment section adapted to assign and feed each of the 4×N unit image signals, output under the control of the memory output control section, to one of the quadrant memories which is associated with the type of quadrant image signal output at that point in time;
- and
- an output control section adapted to treat each of the 4×N unit images as an image to be displayed in a display order, the output control section also adapted to read, at the predetermined intervals, the quadrant image signals, each of which is associated with one of the 4 X N types of quadrant images into which the image to be displayed is divided, from the 4×N types of quadrant memories and output the signals to the display device.
An image processing method of an image processing device for controlling a display device to display a plurality of unit images making up a moving image at predetermined intervals, the image processing device including 4×N (N:
- an arbitrary integer) quadrant memories, each associated with one of 4×N types of quadrant images into which the unit image is divided, the image processing method comprising the steps of:
- separating a moving image signal for the moving image into unit image signals, each of which is associated with one of the 4×N unit images to be displayed successively in time;
- sequentially delaying the output start timing of each of the 4×N unit image signals, separated by the separation section, to the quadrant memory by the predetermined interval as output control and sequentially outputting quadrant image signals, each of which is associated with one of the 4×N types of quadrant images, in a predetermined order over a period equal to 4×N times the predetermined interval;
- assigning and feeding each of the 4×N unit image signals, output under the control of the memory output control section, to one of the quadrant memories which is associated with the type of quadrant image signal output at that point in time;
- and
- treating each of the 4×N unit images as an image to be displayed in a display order, reading, at the predetermined intervals, the quadrant image signals, each of which is associated with one of the 4×N types of quadrant images into which the image to be displayed is divided, from the 4×N types of quadrant memories and outputting the signals to the display device.
A program for causing a computer to control an image processing device operable to control a display device to display a plurality of unit images making up a moving image at predetermined intervals, the image processing device including 4×N (N:
- an arbitrary integer) quadrant memories, each associated with one of 4×N types of quadrant images into which the unit image is divided, the program causing the computer to execute a process comprising the steps of:
- separating a moving image signal for the moving image into unit image signals, each of which is associated with one of the 4×N unit images to be displayed successively in time;
- sequentially delaying the output start timing of each of the 4×N unit image signals, separated by the separation section, to the quadrant memory by the predetermined interval as output control and sequentially outputting quadrant image signals, each of which is associated with one of the 4×N types of quadrant images, in a predetermined order over a period equal to 4×N times the predetermined interval;
- assigning and feeding each of the 4×N unit image signals, output under the control of the memory output control section, to one of the quadrant memories which is associated with the type of quadrant image signal output at that point in time;
- and
- treating each of the 4×N unit images as an image to be displayed in a display order, reading, at the predetermined intervals, the quadrant image signals, each of which is associated with one of the 4×N types of quadrant images into which the image to be displayed is divided, from the 4×N types of quadrant memories and outputting the signals to the display device.
