Abstract: PURPOSE:To improve the sharpness and resolution by making the device suitable for various video equipments or the like, improving the picture quality through the steep processing of a change part of a waveform to improve the picture quality in a natural form without provision of a sense of incongruity to a viewer. CONSTITUTION:Delay circuits 1-1 to 1-6 extract 7 signals at an interval of a predetermined time from an input signal. In order to approximate a signal characteristic curve linking the three signals to be extracted by a sum of a quadratic function term, a linear function term and a constant term, a synthesizer 1-7 synthesizes the 7 signals at a predetermined ratio to obtain the constant term and synthesizers 1-8, 1-9 obtain coefficients of the quadratic function term and the linear function term. Synthesizers 1-11, 1-12 obtain the amplitude and phase from the two coefficients, the phase is subjected to a nonlinear transformation and an output signal in which a waveform change part of the input signal is made steep is obtained from the phase, the coefficient and the amplitude of the quadratic function term at an adder 1-14.

Title: Processing system for exclusive control instruction
Inventor: YOSHIDA AKIRA
IPC: G06F15/17
Filed: 1985-09-19
Abstract: PURPOSE:To operate a common extended memory device with many processors flexibly and efficiently by using coincidence information between data read out from the extended memory device and previously read data as exclusive control information and updating data of this area. CONSTITUTION:When an extended comparison update instruction is applied from a transfer control part 20 of a transfer controller 11 of one processor, an access control part 12 of an extended memory controller 10 converts the address based on the instruction to access an extended memory device 6. Data from the device 6 is stored in a read data register 17. Meanwhile, a selector 13 is controlled by the control part 12 to store data, which is read out previously from the control part 20, in a collation data register 14, and if contents of registers 14 and 17 coincide with each other, a coincidence signal is generated from a comparing circuit 19, and this signal is exclusive control information, and the control part 12 does not accept instructions from devices 11 of the other processors until the update processing of the device 6 is completed. Thus, the common extended memory device is operated flexibly and efficiently by many processors.

Abstract: PURPOSE:To obtain an expanded image with a good quality from image data read from a scanner by compressing raster data to run length data and executing the affine transformation of the border line of respective images to a natural shape while the data quantity is reduced. CONSTITUTION:An input scanner 1 binarizes an image 2a of an original image 2, reads and accommodates into an image memory 3.

Next, a smoothing processing means 4d executes the new edge processing to the intermediate point of the column width and line width between adjoining changing points to respective changing points to exist at the designated section. Thus, the run length data converted to a natural edge are prepared and a registering means 4e registers them to the image memory 3.

Title: Disk discriminating device
Inventor: YOSHIZAWA AKIHIKO
IPC: G11B19/12
Filed: 1985-09-20
Abstract: PURPOSE:To discriminate with a simple constitution whether the group of the disk is concentric circle or spiral by providing the level detecting means with the lapse of time of the track driving signal in the tracking servo state. CONSTITUTION:While a tracking servo system is operated, tracking error signals ST1 and ST2 sample-held by the different timing return to the original position again after one rotation in case of the disk of the concentric circle group, and therefore, the output of a differential amplifier 33 is sufficiently small, and consequently, the output of a comparing device 34 comes to be L. On the other hand, in case of the disk of the spiral group, a light beam is shifted only for the track pitch after one rotation, and therefore, the tracking error signals St1 and ST2 are different from the concentric circle in the output level, and consequently, the comparing output of a reference voltage V0 set smaller than the different output level comes to be H. When the discriminating output is H a jumping pulse generating circuit 31 is operated by the output.
