Abstract
It is possible to perform power control of a printer apparatus for each function module without increasing the circuit scale. A printer apparatus including: a printer unit configured to print an image on a printing medium; a printer control unit configured to control an operation of the printer unit; and a semiconductor integrated circuit performing image processing for input image data and having a first image processing module that performs image processing based on characteristics of the printer unit and a second image processing module that performs image processing independent of characteristics of the printer unit, and power control of the first image processing module of the semiconductor integrated circuit is performed by the printer control unit.
Claims19
A printer apparatus comprising:
- a printer which includes a plurality of devices and prints an image on a printing medium;
- a first processor which controls the plurality of devices of the printer, and sends one or more parameters corresponding to characteristics of at least one device of the plurality of devices;
- and
- a semiconductor integrated circuit which has a first image processing module that performs image data processing using the one or more parameters and sends image data that has been subjected to the image data processing to the first processor, a second image processing module that performs image data processing without using the one or more parameters and a second processor that controls both the image data processing by the first image processing module and the image data processing by the second image processing module,
- wherein the first processor performs a power control of the first image processing module of the semiconductor integrated circuit, and the second processor of the semiconductor integrated circuit performs a power control of the second image processing module of the semiconductor integrated circuit.
