Abstract
An image forming apparatus includes circuitry that binarizes image data, a memory, and a print engine unit that forms an image of the binarized image data. When the image data is low in resolution, the circuitry has the image data stored in the memory and thereafter performs on the image data, detection processing for detecting whether or not the image data includes a predetermined pattern before binarization processing. When the image data is high in resolution, the circuitry binarizes the image data, thereafter has the image data stored in the memory, thereafter further performs multivalue converting processing on the image data, and thereafter performs detection processing.
Claims18
An image forming apparatus comprising:
- circuitry that binarizes image data;
- a memory;
- and
- a print engine unit that forms an image of the binarized image data, wherein
- when the image data is low in resolution, the circuitry has the image data stored in the memory and thereafter performs, on the image data low in resolution, detection processing for detecting whether the image data low in resolution includes a predetermined pattern before binarization processing, and
- when the image data is high in resolution, the circuitry binarizes the image data high in resolution, thereafter has the image data high in resolution stored in the memory, thereafter further performs multivalue converting processing on the image data high in resolution, and thereafter performs the detection processing on the image data high in resolution for detecting whether the image data includes the predetermined pattern.
A method of controlling an image forming apparatus, comprising:
- determining whether image data to be processed is high or low in resolution;
- when the image data is low in resolution, storing the image data low in resolution in a memory and thereafter performing on the image data low in resolution, detection processing for detecting whether the image data low in resolution includes a predetermined pattern before binarization processing;
- when the image data is high in resolution, binarizing the image data high in resolution and thereafter storing the image data high in resolution in the memory;
- and
- when the image data is high in resolution, reading the image data high in resolution from the memory, performing multivalue converting processing on the image data high in resolution, and thereafter performing the detection processing on the image data high in resolution for detecting whether the image data includes the predetermined pattern.
