IPC: G06T1/00
Filed: 1983-12-05
Abstract: PURPOSE:To find a deflection in a short time with a picture processor using an one-dimensional image sensor even when the image forming position repeatedly fluctuates in the vicinity of the reference picture element position by using a detected image forming address.

Title: Yc separator circuit
Inventor: KAMOGAWA KOJI
IPC: H03H15/00
Filed: 1989-09-06
Abstract: PURPOSE:To improve the picture quality to a black white video signal and a special video signal by using a color killer detection output signal of a video/ chroma IC so as to control a switch provided to a color signal addition line for luminance signal separation in a YC separation circuit. CONSTITUTION:When a video signal without a burst reference signal is inputted to a video/chroma IC 8, a color killer circuit in the IC is operated and non- execution of color signal band amplification ia ensured. Since a switch 7 provided to an addition line of a color signal for luminance signal separation of YC separation is controlled by a color killer detection output signal, mis-addition of a luminance signal component in a chrominance sub-carrier band to an input video signal without a burst reference signal is avoided. Thus, the picture quality to a black-and-white video signal and a special video signal is improved.

Inventor: TAKANO MISAO
IPC: H04N1/393
Filed: 1991-09-10
Abstract: PURPOSE:To reduce the deterioration of a picture with comparatively simple constitution while a reduced picture is generated. CONSTITUTION:A frequency-dividing circuit into N-number 51 outputs one first pulse whenever N-number of clocks (b) are inputted. A frequency-dividing circuit into M-number 53 outputs one second pulse whenever M-number of line pulses (c) are inputted. A first data synthesis means outputs a prescribed value as first synthesis data when at least one of picture data fetched in one period of the first pulse takes the prescribed threshold. A second data synthesis means outputs the prescribed value as second synthesis data in respective addresses when at least one first synthesis data fetched into the respective addresses corresponding to a main scan direction position in one period of the second pulse takes the prescribed threshold. Thus, the picture can be reduced at the reduction factor of 1/N in a main scan direction and of 1/M in an auxiliary scan direction.
