Patent number: 8983185Abstract: Disclosed is a method of compressing an image to be stored in a memory to satisfy a memory requirement. A size of a region having a uniform colour in the image is determined. The determined size of the region is compared with the candidate values of the region size threshold. A value is selected from the candidate values as the region size threshold based on the comparison between the estimated data amounts to satisfy the region size threshold and the memory requirement. The edges constituting the region which satisfy the selected value of the region size threshold are compressed losslessly.Type: GrantFiled: March 14, 2013Date of Patent: March 17, 2015Assignee: Canon Kabushiki KaishaInventors: Dixon De Sheng Deng, Wen Tao Lu

Publication number: 20150036160Abstract: A method for combining layers of an image represented using an intermediate format receives at least two layers from the plurality of layers to be combined and estimates resources required to combine the received layers using a first combining operation. The first combining operation comprises at least rasterising data of the received layers. The method attempts to combine the received layers using a second combining operation to produce an output in the intermediate format. In response, the method generates a combined layer for the image by combining the received layers in accordance with a selected one of the first combining operation (merge & flatten) and the second combining operation (merge). The selected combining operation is based on success of the attempt. Desirably the method is performed within a printer apparatus where limited memory and/or computing resources are available for image rendering which could otherwise limit the rendering of complex pages.Type: ApplicationFiled: July 28, 2014Publication date: February 5, 2015Inventors: DIXON DE SHENG DENG, JOSEPH LEIGH BELBIN
