Abstract: An information-processing apparatus includes a nonvolatile memory device configured to store firmware. The information-processing apparatus has a first unit for issuing an instruction to make an operating system execute a shutdown process, and to update the firmware, stored in the nonvolatile memory device, after the operating system has completed the shutdown process. The information-processing apparatus also has a second unit, responsive to the instruction to update the firmware, for updating the firmware only after the operating system has completed the shutdown process.

Abstract: Color data is converted into specific number of gradation data. A table is provided storing a correspondence between gradation data and color data. The gradation data is computed based on Gradation data=K SIN (.alpha.x+.beta.) 0.ltoreq.x.ltoreq.n wherein K is a constant, x is a color data, .beta. defines phase and contributes to modify the gradation data for the color data, and .alpha. defines frequency and contributes to modify a degree of the modification. Two color data having large luminance levels are converted into gradation data having a large difference in gradation level. Control data for changing the values of .alpha. and .beta. in the above equation is input from a keyboard. A user can arbitrarily change the gradation data to be set in the conversion table from the keyboard.
