摘要： A DC-DC converter includes a series circuit including a primary transformer coil and a main switch element connected between a power input terminal and a ground terminal. A secondary transformer coil is connected to a rectifying/smoothing circuit including rectification-side and commutation-side synchronous rectifiers, a smoothing capacitor, and a choke coil. The output voltage from the rectifying/smoothing circuit is supplied to a load connected to a power output terminal. An input voltage detection circuit detects the voltage between the power input terminal and the ground terminal, and supplies a detection signal to a VIN terminal of a switching control circuit. The switching control circuit performs PWM control to maintain a constant output voltage output to the load, reduces the switching frequency when the input voltage input to the VIN terminal is low, and increases the switching frequency in accordance with an increase in the input voltage.

摘要： A problem in conventional electrical color deviation correction is that an awkward step is generated at a border where a pixel is offset by one-pixel-basis correction. Although such a step can be cancelled by less-than-one-pixel-basis correction, this smoothing process in turn generates unevenness in density. To solve these problems, in electrical color deviation correction, a draw command is analyzed to specify a draw position for color deviation correction for each of draw objects. Then, the object is drawn at the specified draw position, and an offset for color deviation correction is performed on an object basis.

摘要： The present invention relates to a device that, in printing of controlling the amount of color materials applied, changes a screen ruling for image formation according to the relationship between luminance and saturation. A first component obtains color component data of a plurality of colors so that the total amount of controlled variable in each pixel does not exceed a first limit amount. A second component obtains color component data of a plurality of colors so that the total amount of controlled variable in each pixel does not exceed a second limit amount by performing color conversion processing different from the color conversion processing with the first component. A third component performs pseudo halftone processing by changing a screen ruling to be applied to the color component data of a plurality of colors obtained by the color conversion processing with the second component from chromaticity of color image data.

摘要： If a larger number of pieces of attribute information are prepared so as to attain advanced input image processing and output image processing, the number of bits of each attribute signal increases, thus increasing the data size of the signal. For this reason, the storage capacity consumed by a storage unit that holds attribute signals may increase, and generation, write, and read speeds of attribute signals may decrease. To solve such problems, attribute regions included in a drawing command are discriminated, the number of types of attribute regions is counted to determine the bitwidth of attribute information based on the number of types of attribute regions, and the attribute information is generated by creating an attribute information table.
