Abstract: PROBLEM TO BE SOLVED: To prevent the removal of a dot image or low contrast image by selecting the output of a 1st selecting means in the case of a nondot or selecting the output of a smoothing filter in the case of a dot. SOLUTION: A dot area separating circuit 12 is operated at the time of both a character mode and a character/photographic mode, and image area separate signal is turned to 'H' at the time of 'dot area' or turned to 'L' at the time of not the 'dot area'.

Title: Optical magnetic disk recording and reproducing device
Inventor: SUZUKI HIROSHI
IPC: G11B11/105
Filed: 1985-11-25
Abstract: PURPOSE:To speed up recording and reproducing processing operations for an erased optical magnetic disk by providing a means detecting a direction where a recording surface in an erasure state is magnetized and inverting the direction of a magnetic field at the time of recording and the polarity of a reproduced signal at the time of reproduction according to a signal obtained from the detection means. CONSTITUTION:When a disk 41 is newly set to a device, a head 42 is positioned in the inner-most unused area 52. At that time, an initialization mode instruction signal 44 is inputted to a magnetization direction switching circuit 43, and the magnetization direction of a magnet 53 is set in one direction. At that time, the reproduced signal 54 is amplified through a photodetecting element 45 and an amplifier 46. If the reproduced signal is '1', the magnetization direction of the magnet 53 is inverted, and an SW 47 and an SW 48 are turned off and on, respectively. If the reproduced signal is '1', the magnetization direction of the magnet 53 remains unchanged, and the SW 47 and the SW 48 are turned on and off, respectively. Thus the direction of a magnetic field at the time of recording and the inversion of polarity at the time of reproduction are controlled, and the polarity of the output 55 of the reproduced signal becomes the same even if recording surfaces are different.

IPC: H04N5/232
Filed: 1984-12-12
Abstract: PURPOSE:To select the movement of a video image on an ITV monitor to attain ease of convenient use by controlling so that the camera rotating speed is inversely proportional to the focus in changing the focus of the ITV camera by zooming. CONSTITUTION:When a signal 29 proportional to a focus (f) is outputted from a focus detection section 23, the camera is rotated to the left/right in a pan angular velocity Wpan inversely proportional to the focus by a pan motor control circuit 30. That is, when the focus (f) is larger by zooming up, the pan angular velocity Wpan is smaller in inverse proportion to the increase, and when the focus (f) gets smaller by zooming down conversely, the pan angular velocity Wpan is larger. Thus, even when an optical lens system 22 is zoomed up, it is easy to match the center axis of the camera with the detail of a picture image.
