摘要:
The image processing device comprises a first function block section formed of functional blocks which require a supply of power so as to maintain the image processing device in an operating state when the power supply is on, and a second function block section formed of functional blocks which need not be supplied with the power so as to maintain the image processing device in an operating state even when the power supply is on. The supply of power to the second function block section can be stopped when desired, while continuing the supply of power to the first function block section, thereby saving the power.

An image processing apparatus implements appropriate image processing on image data stored in a storage unit of the image processing apparatus easily and efficiently, and distributes the image data to an external apparatus. An image format conversion unit implements image processing such as resolution conversion processing, filter processing, γ correction processing, and halftone processing on image data stored in an HDD serving as an image data storage unit so that the image data conform to conditions, such as image quality and format, specified by an external client apparatus. The image-processed image data are then distributed to the external client apparatus.

摘要:
When first image data, which is in a first color space, is converted into second image data, which is in a second color space corresponding to an image output unit. Upon converting the image data, if the first image data is color data, background removal process is switched OFF. Otherwise, the background removal process is switched ON. Thus, it is possible to obtain an image desired by a user.

摘要:
The image processing apparatus comprises an image data control section and a system controller. The image data control section is connected to any one or more of a sensor board unit, an image-memory access control section, an image processor, a video data control section, and a facsimile control unit. The system controller switches, when the image data to be transmitted to the image data control section conflicts with one another, a transmission mode of the image data in conflict with one another. Further, the image-memory access control section and the image processor share jobs of performing image processing on the image data.
摘要:
An image processor has a controller unit connected to at least one of functional units such as an image reading unit, detects a source of input of image data according to a network I/F or a parallel bus I/F. An image-memory access control section transmits the image data input from each of the functional units to a memory group and also transmits the image data stored in the memory group to the functional unit. A system controller controls the overall apparatus and also controls the image-memory access control section according to the input source of the image data to determine an order of transmitting the image data to the memory group.
