Abstract
Abstract AIn information processing apparatus, transfer scan line addresses are monitored within a graphic microprocessor partial update routine to continuously transfer image information of addresses of the same scan line when a two-line simultaneous drive waveform is used to increase a frame frequency. The information processing system comprising an image indormation memory for storing received image information first control means for controlling driving of a display memory, and second control means for controlling the image information memory so that storage of the image information in the image information memory and transfer of the image information stored in the memory to a drive control circuit are synchronized with each other.

A system according to claim 50, wherein said second control means comprises means for controlling said image information memory to inhibit said image information memory to store image information which is being received when a display priority of a graphic event of the image information transferred to said first control means is higher than that of the image information which is being received, and for controlling said image information memory to interrupt transfer of the image information to said first control means and to store the image information which is being received in said image information memory when a display priority of a graphic event of the image information transferred to said first control means is lower than that of the image information which is being received.

An information processing apparatus comprising: a. first means for controlling an image information memory so that received image information is stored in said image information memory and scan line address information for designating a scan line and image information corresponding to the designated scan line are output from said image information memory; b. second means for controlling said image information memory and a drive control circuit so that an output from said image information memory is transferred to said drive control circuit; and c. third means for storing first scan line address information for designating a last scan line obtained when previous scan line scan is interrupted, comparing the first scan line address information with second scan line address information for designating a start scan line for new scan line scan, and decrementing or incrementing the second scan line address information when the first scan line address information is equal to the second scan line address information as a result of comparison.
Claim 68
Dependent Claim
162 words
An information processing apparatus comprising: a. first means for controlling an image information memory so that received image information is stored in said image information memory and scan line address information for designating a scan line and image information corresponding to the designated scan line are output from said image information memory; b. second means for controlling said image information memory and a drive control circuit so that an output from said image information memory is transferred to said drive control circuit; and c. third means for storing first scan line address information for designating a last scan line obtained when previous scan line scan is interrupted, comparing the first scan line address information with second scan line address information for designating a start scan line for new scan line scan, and decrementing or incrementing the second scan line address information when the first scan line address information is equal to the second scan line address information as a result of comparison.
Claim 69
Dependent Claim
173 words
An information processing apparatus comprising: a. first means for controlling an image information memory so that received image information is stored in said image information memory and scan line address information for designating a scan line and image information corresponding to the designated scan line are output from said image information memory; b. second means for controlling said image information memory and a drive control circuit so that an output from said image information memory is transferred to said drive control circuit; and c. third means for storing first scan line address information for designating a last scan line of scan line scan for a predetermined number of scan lines for partial update scan, comparing the first scan line address information with second scan line address information for designating a start scan line of subsequent scan line scan for a new display, and decrementing or incrementing the second scan line address information when the first scan line address information is equal to the second scan line address information as a result of comparison.
Claim 70
Dependent Claim
173 words
An information processing apparatus comprising: a. first means for controlling an image information memory so that received image information is stored in said image information memory and scan line address information for designating a scan line and image information corresponding to the designated scan line are output from said image information memory; b. second means for controlling said image information memory and a drive control circuit so that an output from said image information memory is transferred to said drive control circuit; and c. third means for storing first scan line address information for designating a last scan line of scan line scan for a predetermined number of scan lines for partial update scan, comparing the first scan line address information with second scan line address information for designating a start scan line of subsequent scan line scan for a new display, and decrementing or incrementing the second scan line address information when the first scan line address information is equal to the second scan line address information as a result of comparison.
