摘要:
According to the present invention, when image data are subjected to a quantization processing by an error diffusion method, the generation of a striped pattern which is a cause for the deterioration of picture quality in the error diffusion method is prevented. In the present invention, an original image is read and image data are generated. The image data obtained by reading the original image are quantized by an error diffusion method, and the quantized image data are output and recorded by a thermal-head printer. Furthermore, according to the present invention, an error between the density of an input image and the density of an output image after subjected to a quantization processing by an error diffusion method is perfectly preserved. In an image processing apparatus for performing a quantization by dispersing an error between input image data and output image data when the input image data are quantized to image data of surrounding picture elements, an error between the input image data and the output image data is operated, the operated error is subjected to a predetermined weighing processing, the error subjected to the weighing processing is dispersed to surrounding picture elements, and a surplus of the error generated at the weighing processing is corrected.
摘要:
There is disclosed a thermal transfer printer for image recording by ink transfer from an ink sheet (14) onto a recording sheet (11), capable of stable sheet transportation and improvement in image quality. The printer has transport mechanisms (17,18) for the ink sheet and the recording sheet (12,16), a thermal head (13) for heating the ink sheet, and a controller. If a next recording operation is instructed at the end of a preceding recording operation, the controller starts the transportation of the sheets and at the same time activates the thermal head (13) with an energy smaller than in the ordinary image recording, thus effecting pre-heating of the thermal head, prior to the start of next recording operation.

The present invention provides a thermal printer which can perform both a heat-sensitive recording operation and a heat-transfer recording operation, comprises a recording medium loading portion for removably receiving a recording medium (11) for the heat-sensitive recording operation and a recording medium for the heat-transfer recording operation; an ink sheet loading portion (70) for removably receiving an ink sheet (14) used with the heat-transfer recording operation; a recording means for recording an image on the recording medium (11); and a control means (101) for energizing the recording means to heat a predetermined number of dots when the image is recorded on the recording medium for the heat-transfer recording operation by means of the recording means and for energizing the recording means to heat a number of dots larger than the predetermined number of dots when the image is recorded on the recording medium for the heat-sensitive recording operation. The present invention also provides a facsimile system comprising the above-mentioned thermal printer, a reading means for reading an original image, and a transmission/reception means for transmitting and receiving an image signal.
