Image processing apparatus that performs different processes in parallel, method, and program

A method performed in an image processing apparatus, comprising:

• executing a first process of outputting raster data obtained by developing print data;
• generating image determination-purpose data on the basis of divided data obtained by dividing the raster data, and executing a second process of storing the generated image determination-purpose data in a buffer;
• executing a third process of determining whether or not an image presented by the image determination-purpose data stored in the buffer contains a specific image;
• generating schedule information indicating a time schedule of the first, second, and third processes, determining each set of raster data on whether or not the time schedule indicated by the schedule information satisfies an overflow condition;
• and
• upon having determined that the time schedule satisfies the overflow condition, extending the buffer,
• wherein the overflow condition is a condition that at least part of a period of the second process overlaps with at least part of a period during which the image determination-purpose data for which the third process has not been completed occupies an entire area of the buffer.

A non-transitory recording medium storing a computer readable program causing a computer of an image processing apparatus to execute an information processing method comprising:

• executing a first process of outputting raster data obtained by developing print data;
• generating image determination-purpose data on the basis of divided data obtained by dividing the raster data, and executing a second process of storing the generated image determination-purpose data in a buffer;
• executing a third process of determining whether or not an image presented by the image determination-purpose data stored in the buffer contains a specific image;
• generating schedule information indicating a time schedule of the first, second, and third processes,
• determining each set of raster data on whether or not the time schedule indicated by the schedule information satisfies an overflow condition;
• and
• upon having determined that the time schedule satisfies the overflow condition, extending the buffer,
• wherein the overflow condition is a condition that at least part of a period of the second process overlaps with at least part of a period during which the image determination-purpose data for which the third process has not been completed occupies an entire area of the buffer.
