    • This invention efficiently implements encoding processes corresponding to respective image processing functions while minimizing the memory use size in the apparatus in an image processing apparatus having many image processing functions. A data processing apparatus of this invention includes a data reception unit for receiving at least data of a first format for respective pages, a data conversion unit for converting the data of the first format into data of a second format, a page data management unit for managing the data of the first and second formats in first and second page data in association with each other, and a control unit for monitoring a storage state of the data of the first format in the memory, and permitting a predetermined process for the data of the first format in accordance with the storage state. When the control unit determines that storage of the data of the first format in the memory is complete, the control unit permits the data conversion unit to start a data conversion operation from the first format to the second format. Also, the control unit monitors completion of the conversion operation of the data conversion unit and a storage state of the data of the second format in the memory, and permits a predetermined process for the data of the second format in accordance with the storage state.
    • 本发明在具有许多图像处理功能的图像处理装置中有效地实现与各个图像处理功能相对应的编码处理,同时最小化装置中的存储器使用大小。 本发明的数据处理装置包括数据接收单元,用于至少接收用于各页的第一格式的数据;数据转换单元,用于将第一格式的数据转换为第二格式的数据;页数据管理单元,用于 相互关联地管理第一和第二页数据中的第一和第二格式的数据;以及控制单元,用于监视存储器中的第一格式的数据的存储状态,并且允许对数据的预定处理 第一种格式按照存储状态。 当控制单元确定存储器中的第一格式的数据的存储完成时,控制单元允许数据转换单元从第一格式开始到第二格式的数据转换操作。 此外,控制单元监视数据转换单元的转换操作的完成和存储器中的第二格式的数据的存储状态,并且根据存储状态允许针对第二格式的数据的预定处理。

    • Disclosed is an image processing apparatus having a large number of image processing functions, in which resources necessary for code processing units can be suppressed while a large-scale decline in performance is prevented. The apparatus includes a plurality of code processing unit (310) for executing coding and decoding of image data, and a plurality of request-source task units (301 to 308) (print function, scanner function and FAX transceive function). The request-source task units request any ones of the plurality of code converters to perform a code conversion of image data. The number of request-source task units is greater than the number of code converters and a degree of priority has been set for each one. A code-processing acquisition determination unit (309) always assigns the plurality of code converting units to processing requests from request-source task units (301 to 304) having a high priority and, if there is an idle code converting unit among the plurality of code converting units, assigns the code converting unit to a processing request from request-source task unit (305 to 308) having a low priority.
    • 公开了一种具有大量图像处理功能的图像处理装置,其中可以抑制代码处理单元所需的资源,同时防止性能的大幅下降。 该装置包括用于执行图像数据的编码和解码的多个代码处理单元(310)和多个请求源任务单元(301至308)(打印功能,扫描仪功能和传真收发功能)。 请求源任务单元请求多个代码转换器中的任一个执行图像数据的代码转换。 请求源任务单元的数量大于代码转换器的数量,并且为每个单元设置了优先级。 代码处理获取确定单元(309)总是将多个代码转换单元分配给具有高优先级的请求源任务单元(301至304)的处理请求,并且如果在多个代码转换单元中存在空闲代码转换单元 代码转换单元,将代码转换单元分配给具有低优先级的请求源任务单元(305至308)的处理请求。
