    摘要： An image forming apparatus which varies the blending ratio by which color-seperated image signals are blended together to form a monochromatic image. The apparatus inputs a plurality of image signals which have been color-separated, and synthesizes the plurality of image signals by blending to form a monochromatic image. A density regulating mechanism regulates the density of the monochromatic image to a predetermined density level, and the apparatus varies the blending ratio of the synthesized plurality of image signals based on the predetermined density level.

    摘要： An image processing apparatus having a first mode for processing electrical signals by a pre-scan operation and a second mode for processing electrical signals by a main scan operation. The first mode forms a histogram on the basis of electrical signals obtained by the pre-scan operation, and detects predetermined feature points from the formed histogram. A table is formed for converting signal levels of the electrical signals according to the detected predetermined feature points of the histogram based on the image type of the original. The second mode generates reproduction signals from electrical signals obtained by the main scan operation in accordance with the table.

    摘要： The invention is directed to an arrangement for controlling a braking force applied to each of front and rear road wheels of a four-wheel drive vehicle depending upon a braking condition, with a hydraulic braking pressure supplied to each of the wheel brake cylinders through an actuator. The actuator is controlled by a braking force controller into which output signals of wheel speed sensors are fed. On the basis of the wheel speeds detected by the sensors, a wheel acceleration of each road wheel is calculated. Also, an oscillation of a relative movement between the front and rear road wheels is determined. And, a coefficient of friction of a road is estimated in accordance with the wheel acceleration and the oscillation. For example, it is estimated that the road is of a relatively low coefficient of friction, when a mean wheel acceleration of all road wheels becomes less than a predetermined standard acceleration, and when the oscillation is caused to exceed a predetermined level. Then, the hydraulic braking pressure applied to each of the wheel brake cylinders is controlled by the braking force controller in accordance with the estimated coefficient of friction and in response to each wheel speed.
