摘要： There is provided an image processing apparatus for applying an adjusting process to an image including multicolor image signals. An image area including a pixel to be processed is extracted, and one representative signal value is generated from signal values corresponding to a plurality of colors of pixels included in the image area (S2501). A feature amount associated with the image area is calculated based on the representative signal value (S2503, S2505, S2511), and a substitute candidate pixel common to the plurality of colors is selected from the image area based on the calculated feature amount (S2512). Signal values of the pixel to be processed are substituted by new pixel values, which are calculated from the signal values of the pixel to be processed and signal values of the substitute candidate pixel.

摘要： There is provided an image processing apparatus which enables high-speed processing with simplified multiplications and divisions even in the case of error diffusion comprised of a combination of processes of two or more colors. The image processing apparatus performs error diffusion on multivalued image data composed of a plurality of density components and outputs the result of the error diffusion. A plurality of error tables are stored in a storage device. One error table is selected from the plurality of error tables according to a density value of a first density component among the plurality of density components and a density value of at least one other density component when performing the error diffusion on the first density component. A CPU performs the error diffusion on the multivalued image data using the selected error table.

摘要： Upon outputting halftone image data to an output device, density transformation is prevalently done to improve image quality. Density transformation corresponds to linear gamma correction, and cannot correct any color fog and the like of a photo image. Hence, lightness/color difference information of halftone image data is acquired on the basis of low-frequency components of frequency data obtained by transforming halftone image data into spatial frequency components, and a lightness/color difference transform amount of the halftone image data is set on the basis of the acquired lightness/color difference information.

摘要： An adapter capable of communicating with an image supply device and an image output device and allowing direct printing even when a plurality of images are transferred at the same time from image supply devices. The adapter transmits a print request associated with a first image to the image output device. If acquisition of a second image is completed before acquisition of the first image completed, the adapter transfers the second image instead of the first image as the image to be printed.

摘要： A plurality of scan electrodes and data electrodes, and a self-emission layer disposed between the two electrodes are provided, wherein a scan voltage is supplied sequentially to the scan electrodes, and data voltage that corresponds to the display signal data is supplied to the data electrodes. The emission layer of the portions at the intersection between the two electrodes defines pixels in two-dimensional arrangement. A single frame period is divided into a plurality of sub-fields, and the weight of emission luminance is set so that gradation is expressed by a combination of emission luminance in the sub-fields. The scan voltage has a waveform that corresponds to the weight in each sub-field, and the data electrodes are selectively put into on state by the data voltage in accordance with the display signal data. An emission luminance that corresponds to the weight is obtained with a voltage applied to the emission layer of each pixel between the scan electrodes and the data electrodes.

摘要： An object of this invention is to prevent an increase in energy applied to a heating element and prolong the service life of a printhead even when the temperature of the printing element having a negative temperature coefficient rises and the resistance of the heating element decreases upon controlling a switching element for controlling a current flowing through the heating element so as to make energy as constant as possible. For this purpose, a printhead having a plurality of heating elements connected to a common power supply comprises: a switching element which is series-connected to the heating element and controls driving of the heating element at a voltage applied to a control terminal; a constant voltage source using a common power supply as a reference; a wiring resistance generated at a connection wiring line serial-connected to the heating element; and a voltage control circuit which controls to make the potential difference between both ends of the wiring resistance equal to the voltage of the constant voltage source when driving the heating element. Then, a current flowing through the heating element is made constant without any influence of the temperature of the heating element.
