Abstract: An image processing apparatus includes a dense-light color decomposition unit that decomposes, into dense and light color components, elementary color components out of elementary color components in first print image data in a color space of a printer, in order to generate dense-light color decomposed second print image data, a converter unit that converts the color value represented by the combination of the elementary color components in the color space of the printer into a color value represented by a combination of elementary color components in a color space of a display, and supplies the color value as a conversion result to the display, and a supplying unit that extracts, from the print image data, a color component selected as a target of composite display from among the color components and supplies the extracted color component to the converter unit.

Abstract: To include a comparison circuit that generates comparison results by comparing plural pieces of data simultaneously read via data lines with expected values, an AND gate that activates a first determination signal in response to a fact that at least one of the comparison results indicates a mismatch, and an OR gate that activates a second determination signal in response to a fact that all the comparison results indicate a mismatch. With this arrangement, when a detection test of a defective address is performed in a wafer state, a defect of a column selection line can be detected.

Abstract: The disclosed invention provides a device for driving a piezoelectric element, making it possible to make an output voltage follow a control voltage during a discharging action. A charging circuit charges a piezo element through a first node. A discharging circuit discharges electric charge charged in the piezo element through the first node. A control circuit makes switching to cause the discharging circuit to perform a discharging action or cause the charging circuit to perform a charging action, based on a comparison between the magnitude of a voltage being applied to the piezo element and the magnitude of a control voltage.
