  • Patent number: 10296130
    Abstract: An information processing apparatus includes an operation unit equipped with a touch screen disposed on a display device. Coordinate information indicating a detected touch position is output from the touch screen to a CPU. The CPU sequentially stores coordinate information about respective touch positions in a memory. The CPU determines whether there is any change in a moving direction of the touch position, with reference to a history of the touch positions. If it is determined that the moving direction of the touch position has changed, the CPU invalidates the touch position detected after determination of the change until action of a touch-up operation.

  • Patent number: 10295924
    Abstract: An image forming apparatus is capable of switching thresholds for deciding a color registration amount from a pattern image. A controller controls image forming units to form first and second color patterns of different colors on a rotational image bearing member. The second color pattern is formed at an upstream side of the first color pattern in a rotational direction of the image bearing member. The controller controls a sensor to detect the color patterns. A comparator compares a detection result by the sensor with a threshold, and outputs an output value according to a comparison result. The controller controls the color registration according to the output value. The controller sets a second threshold for the second color pattern based on an edge timing of the output value from the comparator according to the comparison result between the detection result about the first color pattern and a first threshold.
