摘要： A motor control device is used for controlling a DC motor for secondary paper feeding in, for example, a copying machine. Secondary paper feeding of paper to a transfer drum is achieved by the dedicated DC motor. The DC motor is rotated at a high speed at the time of starting the secondary paper feeding and is decelerated up to a process speed after a constant time. At the time of the deceleration, the control device applies a short-circuiting brake to the motor. In the short-circuiting brake, there is no variation in braking, thereby to make it possible to reliably decrease the speed of the motor. The braking is released at the timing at which an FG clock corresponding to the rotation of the motor is synchronized with a command clock representing the process speed. Consequently, a braking operation is reliably released the instant the speed of the motor reaches a desired process speed.

摘要： An image processing apparatus is provided which performs image restoration as necessary while a computing processing burden based on an image restoration algorithm is reduced. RAW data of a blurred image is input to an RGB interpolation section. The RGB interpolation section generates an R component image, a G component image, and a B component image based on the RAW data. The G component image is input to an image restoration processing section and the R and B component images are input to an RGB to YCC section. The image restoration processing section performs an image restoration process based on a predetermined image restoration algorithm by using a PSF image representing a predetermined point spread function. The RGB to YCC section generates a brightness component image Y and color difference component images CR and CB based on the G component image having been subjected to the image restoration process and the R and B component images which was not subjected to any image restoration process.

摘要： An image processing apparatus is provided which executes image restoration processing by performing a iterative computation on a degradation image. The image processing apparatus is capable of maintaining the quality of a restored image and completing the iterative computation sufficiently quickly. The first image restoration processor creates a first restored image f1 for a degradation image g by calculating an inverse filter H−1 based on Fourier transform H of a deterioration function h, multiplying the inverse filter H−1 and Fourier transform G of the degradation image g, and performing inverse Fourier transform on the result of the multiplication. The second image restoration processor creates a second restored image f2 by a iterative computation using the first restored image f1 and the deterioration function h.

摘要： Upon initiation of a initiation processing by a task management, reference is made to a initiation table for processing of initiation, and processing of measurement is performed by an input measurement processing in response to the preset timing. Then the input value is stored in a input value storage buffer. When an application program is acquired, an input value acquisition processing is initiated, the input value is from the buffer, and is transferred to the application program. When the application program is set, an output value updating is initiated, the output value having been transferred from the application program is updated, and the result is stored in an output value storage buffer. Further, output processing means is initiated in response to the timing preset on the initiation table and an output value is outputted from the output value storage buffer.
