An image processing apparatus comprises: a division unit that divides input data on a predetermined basis; a generation unit that generates, from the input data divided by the division unit, intermediate data on the predetermined basis; an updating unit that updates the intermediate data by converting rendering contents of the intermediate data generated by the generation unit into image data; a transfer unit that transfers, each time the generation unit generates the intermediate data, the generated intermediate data to a raster image processing unit; and a determination unit that determines, before the transfer unit transfers first intermediate data generated from the input data, whether to perform updating for each intermediate data corresponding to the input data by the updating unit based on a rendering command of the input data or the first intermediate data.

In a case where it is determined that image processing on image data is executed not in parallel with other image processing different from the image processing and printing of an image of the document is started after reading of an image of a first page of the document is completed, a transfer rate of image data from an image reading unit to an image processing unit is set to a predetermined transfer rate. Whereas in a case where it is determined that the image processing on image data is executed not in parallel with the other image processing different from the image processing and printing of the image of the document is started without waiting for the reading of the image of the first page of the document to be completed, the transfer rate is set to a transfer rate lower than the predetermined transfer rate.

An image processing apparatus capable of performing a plurality of pieces of image processing including scan processing of a document in parallel with a scanner unit. In the scan processing, when the document is conveyed, the scanner unit receives a first instruction for setting a transfer rate and sets the transfer rate based on the first instruction, and when the image data is transferred, the scanner unit receives a second instruction for setting the transfer rate. When the transfer rate indicated by the first instruction and the transfer rate indicated by the second instruction are different, the image data is transmitted after changing the transfer rate, based on the second instruction. When the transfer rate indicated by the first instruction and the transfer rate indicated by the second instruction are identical, the image data is transmitted without changing the transfer rate set based on the first instruction.

A liquid discharging apparatus includes: a head having nozzles; and a controller. The controller executes: a first recording processing of discharging liquid from the nozzles with respect to a first area of a recording medium, based on first image data, and a second recording processing of discharging the liquid from the nozzles with respect to a second area, of the recording medium, which overlaps with or is adjacent to the first area based on second image data, after a predetermined time has elapsed since the first recording processing. The controller further executes a determining processing of determining the predetermined time based on color information of the first image data.
