摘要:
A display controller of a flat display apparatus which performs multiple color display and variable color display for display data read out of a lookup table. The lookup table comprises a parallel lookup table which has n (n.gtoreq.2) registers for storing color information and m selectors which receive n pieces of color information independently from the n registers, each select one of n pieces of color information, and deliver m pieces of color information simultaneously. The controller further comprises a data selector which selectively delivers the output of other register in the parallel lookup table in place of the register which has been made the read access.

A data processing apparatus which includes a display unit and a power supply controller for supplying power to the display unit. The display unit has a display screen and a back light controller. The power supply controller comprises a switch, at least one output line for receiving the power from the switch and for supplying therethrough the power to electronic devices, a delay circuit for receiving the power from the switch and when the switch is turned ON to start supply of the power, for outputting the power after passage of a predetermined time from the start of the power supply, and a second output line for supplying the power from the delay circuit to the back light controller therethrough. The display unit has a memory means for storing therein a luminance data on the display screen through the back light controller when the power supply is turned OFF and for determining an output state of the display unit through the back light controller on the basis of the luminance data read out from the memory means when the power supply is turned ON. Further, the data processing apparatus has a means for invalidating output of a display data to be output onto the display screen and a means, after the display data is invalidated, for reducing a frequency of a timing signal or invalidating output of the timing signal for the display unit.

An information processing apparatus includes in its body at least a power supply unit, a disk type storage and a printed circuit board arranged in a predetermined order and further has a keyboard unit which can be sandwiched between the display unit and a keyboard unit supporting portion extending from the body by pivotally moving the display unit. A detector for detecting the detachment of the keyboard unit from the body may be provided to restrict the range of pivotal movement of the display unit in accordance with a detection signal of the detector. Further, the display unit may be provided with pilot light emitting portions, thereby making it possible to recognize a condition of the information processing apparatus.

A one-dimensional image sensor comprising a solid image pick-up element takes images in sequence, and generates an image signal. Clock pulses from a frequency variable type clock pulse generator having a frequency which varies in correspondence to a control signal are supplied to a one-dimensional image sensor, thereby image signals are outputted in sequence. The image signal is amplified by an amplifier and inputted to a comparator and compared with a reference signal. A frequency variable range of the frequency variable type clock pulse generator is set higher than the cut-off frequency of the amplifier, and the binary level output by the comparator is substantially the same as the image inputted to the one-dimensional image sensor and control is effected by the variable frequency of the clock pulses.

An optical signal receiver comprising an opto-electric converter for converting an optical signal transmitted from a remotely opposed transmitter into an electric signal, a reproduction circuit for reproducing a data signal from an output of the opto-electric converter, a fixed signal generation circuit for generating a fixed signal having a logic level fixed to 0 or 1, a switch for selectively outputting either the data signal reproduced by the reproduction circuit or the fixed signal generated by the fixed signal generation circuit, and a control circuit for detecting an abnormal state of optical signal transmission and controlling the switch. The control circuit is adapted to output the fixed signal from the switch, when it detects the abnormal state while outputting the data signal from the switch. The optical signal receiver constitutes an optical space transmission system with transmitter for transmitting an optical signal.
