摘要： An image processing device includes circuitry to segment an image corresponding to input image data into a black text area including black text and a non-black text area of the image data other than the black text area, perform a first type of color correction on pixel data items in the black text area and a second type of color correction on pixel data items in the non-black text area to generate a processed image, and determine whether or not the image is a color image using the processed image. The second type of color correction is different from the first type of color correction.

摘要： In a drive control apparatus for an electric actuator to be activated under control of a changeover switch, the drive control apparatus including a power transistor arranged to supply therethrough the power to the electric actuator from an electric power source in response to operation of the changeover switch, a presumptive temperature of the power transistor is previously memorized and renewed in consideration with an increment of temperature change caused by consumption of the power when the electric actuator has been activated. The presumptive temperature is further renewed in consideration with a decrement of temperature change caused by lapse of time after the electric actuator has been deactivated. The power supply to the electric actuator is permitted only when the presumptive temperature is lower than a predetermined value. When the presumptive temperature becomes higher than the predetermined value, the power supply to the electric actuator is prohibited.

摘要： In an electric control apparatus for a clutch mechanism provided therein with a reversible electric motor which is activated under control of a changeover switch to engage the clutch mechanism in its forward rotation and to disengage the clutch mechanism in its reverse rotation, a first period of time is set when the changeover switch has been operated to engage the clutch mechanism, and a second period of time is set when the changeover switch has been operated to disengage the clutch mechanism. The first period of time represents a power supply time during which the electric motor is activated to cause full engagement of the clutch mechanism. The second period of time is defined to be longer than the first period of time and represents a power supply time during which the electric motor is activated to cause full disengagement of the clutch mechanism.
