AI Technical Summary
【0012】 本発明によれば、画像処理の前段において各ブロック内の画素数に対応する値を取得するため、用紙搬送が進行する前の定着温度の制御が可能になる。また、画像処理の前段における分割により予め生成されたブロックを利用して画素数に対応する値を取得するため、ブロックごとに設けられるカウンタ以外の、ブロックの位置情報等の取得のための追加のハードウェアを新たに必要としない。その結果、ハードウェアリソースを増大させることなく、短い印刷時間で、適切に定着温度制御を行うことができる。

Abstract
Claims
1. An image forming unit that forms a toner image on paper based on image data, A fixing unit that heats and pressurizes the paper on which the toner image is formed, A transport unit that transports the aforementioned paper to the image forming unit and the fixing unit, The system includes a control unit that performs image processing on the image data and paper transport operations by the transport unit in parallel. The control unit, A predetermined first process is performed before the image processing that enables the acquisition of the number of pixels in the image data, and a predetermined second process, different from the first process, is performed after the image processing. In the preceding stage of the image processing, the image data is divided into blocks of a predetermined size that serve as image processing units, and a value corresponding to the number of pixels in each block is obtained. An image forming apparatus that controls the fixing temperature of the fixing unit based on a value corresponding to the acquired number of pixels.
2. The image forming apparatus according to claim 1, wherein the control unit performs a color conversion process as the first process.
3. The image forming apparatus according to claim 1, wherein the control unit classifies the acquired number of pixels into one of several groups by dividing them by at least one threshold, acquires a value corresponding to the classified group as a converted value, and controls the fixing temperature of the fixing unit based on the acquired converted value.
