摘要： The invention provides an easy and simple method of converting the resolution of image data, which is capable of generating the high-resolution image data without incongruity, does not make a circuit in the display device complicated and does not increase the power consumption. This invention can include a portable terminal device, such as a mobile telephone or a PDA, that processes and displays image data transmitted from the outside. Image data with a plurality of grayscales can be displayed by controlling the display state of each pixel in a display unit in accordance with grayscale control pulses corresponding to the number of grayscales. For example, when a 64 grayscale display is performed, a grayscale level is defined using sixty four grayscale control pulses. Thus, it is possible to emit light from pixels in the display unit by sixty four grayscale levels. Further, the resolution converting device can generate pseudo-high-resolution image data obtained by increasing the number of pixels of original image data by n multiplication and by reducing the number of grayscales of the original image data to 1/n. When displaying the pseudo-high-resolution image data, the number of grayscale control pulses is changed to 1/n by a halftone controller. That is, in the pseudo-high-resolution image data, the number of grayscales is 1/n. Therefore, the number of grayscale control pulses used for halftone display may be 1/n in accordance with the number of grayscales. Therefore, the low-resolution image data can be displayed without incongruity by converting the resolution, also, it is possible to reduce power consumption of the display unit by the reduced amount of the number of grayscale levels pulses.

摘要翻译： 本发明提供了一种简单且简单的转换图像数据的分辨率的方法，其能够不引起高分辨率图像数据的产生，而不会使显示装置中的电路复杂化，并且不增加功耗。 本发明可以包括处理和显示从外部发送的图像数据的诸如移动电话或PDA的便携式终端设备。 可以通过根据与灰度数对应的灰度级控制脉冲控制显示单元中的每个像素的显示状态来显示具有多个灰度的图像数据。 例如，当执行64灰阶显示时，使用六十六个灰度级控制脉冲来定义灰度级。 因此，可以从显示单元中的像素发射六十六个灰度级的光。 此外，分辨率转换装置可以生成通过相乘乘以原始图像数据的像素数量并将原始图像数据的灰度数减少到1 / n而获得的伪高分辨率图像数据。 当显示伪高分辨率图像数据时，通过半色调控制器将灰度级控制脉冲的数量改变为1 / n。 也就是说，在伪高分辨率图像数据中，灰度数为1 / n。 因此，用于半色调显示的灰度控制脉冲的数量可以是根据灰度数的1 / n。 因此，可以通过转换分辨率来显示低分辨率图像数据而不一致，还可以通过减少灰度级别脉冲数量来减少显示单元的功耗。

摘要： A printing control system controlling a printer performing a printing operation by ejecting a plurality of ink including specific color ink or special ink. An ejection order specifying section specifies an order of ejecting the ink when the plurality of ink including the specific color ink or the special ink is ejected to perform the printing operation. A print data generating section generates print data for controlling the ejection of the ink every rank on the basis of the order specified by the ejection order specifying section. A printing control section allows the plurality of ink to be ejected in the order specified by the ejection order specifying section by sequentially controlling the printer on the basis of the print data sequentially acquired from the first rank among the print data of all the ranks generated by the print data generating section.

摘要： When an N-times density binary image having N+1 tones is compressed, only the tone of each pixel is converted into a compressed code. The compressed code has a number of bits necessary and sufficient to distinguish between the tones. When a triple-density image having 4 tones is compressed, for example, the tone of each pixel is converted into a 2-bit compressed code. When the original N-times density is restored from the compressed code, there is formed a dot pattern in which the number of dots corresponding to the tone, as represented by the compressed code of each pixel, are situated closer to the darker one of the two adjoining pixels.
