Title: Recording device and recording and reproducing device for information signal
Inventor: FURUHATA TAKASHI
IPC: H04N9/815
Filed: 1994-11-21
Abstract: PURPOSE:To make the size and weight of the device small and light and to reduce the cost by minimizing the redundancy of a broad band video signal and recording the signal separately on plural channels at a minimum occupancy band so as to reduce the recording density per channel. CONSTITUTION:Three primary color video signals R, G, B are inputted respectively to terminals 1a, 1b, 1c as video signals. They are given to an encoder 10 respectively, in which matrix arithmetic operation is conducted and the signals are converted into a luminance signal Y0 and two chrominance signals C01, C02. Filters 12, 13 are used to apply band limit to the signals as required in horizontal and vertical directions. A time axis conversion circuit 100 eliminates either or both of a vertical redundant period tau1 in a vertical blanking period and a horizontal redundant period tau2 in a horizontal blanking period included in the original video signal to reduce the required band. The luminance signal YO is divided into two channels and an information signal including the narrow band chrominance signals C01, C02 of two channels is converted into a single channel signal C0, resulting in decreasing number of channels to a half.

Title: Solid-state camera
Inventor: TAKAOKA TETSUYA
IPC: H04N5/359
Filed: 1989-11-02
Abstract: PURPOSE:To prevent a control failure to transmit charges induced by excess charges by shallowing the depth of a second conductivity type well in a photodiode region and directly under its channel respectively. CONSTITUTION:P-type impurities are introduced into an N-type silicon substrate 8 selectively so that a P-type well 2 having shallow parts 7-1 and 7-2 may be formed. Then, an N-type buried channel in a photodiode region and a vertical shift register is formed thereon by introducing N-type impurities. A charge transfer electrode 4r and a charge readable and transmission electrode 3j are alternately installed on the vertical shift register. When a positive voltage is applied to the electrode 3j, the charge generated in the photodiode is read out to the vertical shift. When the amount of electric charge exceeds the capacity of the vertical shift register, the amount of electric charge which exceeds the capacity of the vertical shift register is attracted to the substrate 8 so that it may drop effectively. This construction makes it possible to prevent the generation of a transmission control failure induced by the flooded change in the vertical shift register.
