Abstract: There is provided a print control device that causes a printing device to perform printing, the print control device including: a specifying section that specifies a print target from a captured image captured by an image capturing sensor; a display section that displays, on a display, a screen in which a trimmed image is superimposed on the captured image, the trimmed image being obtained by trimming a preview image of original print data in accordance with the print target; a setting receiving section that receives a setting of a relative position of the preview image with respect to the print target; a print instruction receiving section that receives a print instruction at the relative position; and a control section that causes the printing device to perform printing on the print target based on the original print data and the relative position according to the print instruction.

Abstract: A display driver comprises drop amount calculation circuitry and digital gamma correction circuitry. The drop amount calculation circuitry is configured to calculate a drop amount of a power source voltage supplied to a display panel from a setting value. The digital gamma correction circuitry is configured to perform digital gamma correction on an input image data based on the drop amount.

Abstract: Provided is a display driver which can be used in common in any of COF mounting and COG mounting. In the display driver, a position (or write/output position) of display data output by an output circuit can be changed along a direction of an array of external output terminals S1 to S540 according to mode data, whereby an array of external output terminals to use for output can be selected from more than one kind of arrays different in layout pitch. Therefore, the display driver can be used in display panels with signals lines having different pitches serving to receive drive signals from the display driver and in addition, used in common in any of COF mounting and COG mounting which are different from each other in the pitch of mounting wiring lines.

Abstract: Low power consumption is realized focusing on the refresh interval of a low leakage display panel. Display systems and microcomputers are described herein. One embodiment of a display system includes a display driver. The driver receives an enable signal from the outside, stops the display operation of an internal circuit in an inactive state of the enable signal, and resumes the display operation of the internal circuit in an active state. Instead of the enable signal, a command supplied from the outside may be used. When resuming the display operation, the display driver performs control to make the start timing of the display operation earlier for a circuit that requires a long time for activation. A microcomputer that outputs an enable signal or a command controls the output or the output stop of display data according to the state of the enable signal or the command.
