    Abstract: It is provided an image processing apparatus comprising: reception means for receiving image date sent from a transmission-side apparatus; discrimination means for discriminating whether the image data received by the reception means is a character image or a halftone image; and processing means for performing segmentation processing of the reception data, wherein when the discrimination means discrimitaes that the reception image data is a character image, the processing means performs interpolation processing on the basis of reception image data in a predetermined area to perform segmentation processing of image data of a pixel of interest, so that the apparatus can perform segmentation processing of input data by simple control at high speed and low cost.

    Abstract: An image recording apparatus includes a FAX unit (1) and a printer unit (2). The printer unit (2) has an ink-jet printing head (205), and records an image in accordance with image data received by the FAX unit (1). In this apparatus, when the power supply is turned on, the printer unit (2) performs a hard power-ON initialization process to initialize a watch-dog timer, registers, the work area of a RAM, and the like, and also initializes the RAM to erase data left in buffers. Thereafter, the printer unit transfers to a standby state. When a print request or a printer setting request is generated in the standby state, a soft power supply initialization process is executed to perform checking of the RAM, initialization of the work area, and initialization of carriage control and paper feed control, and the like. In the standby state, LEDs and the like of the printer unit are kept OFF. An operation error of the printer unit caused by remaining data can be prevented, and reliability of the apparatus can be improved. In addition, unnecessary power consumption can be prevented.
