IPC: B41F33/06
Filed: 1986-07-07
Abstract: PURPOSE:To prevent hunting by adding a control of the tension of a film to a control by a differential mechanism. CONSTITUTION:The titled apparatus comprises an infeed roll 5 for giving a tension to a film 2, a printing unit 6, a detector 22 for detecting a printing by said unit, and differential mechanisms DF1 and DF2 provided in a drive mechanism for driving printing members 6a and 6b of the printing unit 6. A signal 23 of the detector 22 is inputted to these differential mechanisms DF1 and DF2 to control the printing. The apparatus is so designed that the signal 23 of the detector 22 is inputted also to a speed change gear 27 provided in the drive mechanism for the infeed roll 5 so as to control the tension of the film 2. Such a control by the tension of the film as described above is a slow control (integral control). Therefore it tends to delay the control by the differential mechanisms, and thus hunting of the control is prevented.

Title: Noise removing device
Inventor: NAGASHIMA YOSHITAKE
IPC: H04N5/21
Filed: 1988-06-30
Abstract: PURPOSE:To obtain a still picture in which noise is effectively removed by executing noise removal through a time low-pass filter when a change quantity in a time base direction is equal to or below a normal value V1, through a space low-pass filter when it is equal to or above a normal value V2, and in mixing and fetching outputs from both filters when a change quantity V is between the V1 and V2. CONSTITUTION:By a movement detecting part 2, a movement quantity in each picture element unit is detected. When the movement quantity V of an image is smaller than the lower limit V1, only the output signal of a time low-pass filter 3 is sent and stored to a frame memory 9. To the contrary, only the output signal of a space low-pass filter 4, in which the movement quantity V of the image is larger than a rise V2, is sent and stored to the frame memory 9. When the movement quantity V is in a medium degree, the output, in which both outputs of the time low-pass filter 3 and space low-pass filter 4 are multiplied with coefficients K and 1-K, is stored in to the frame memory 9. Thus, to any image, the still picture can be obtained in which the noise is effectively removed from a video signal without omitting a signal.
