Patent number: 5321509Abstract: Apparatus and method for controlling a charge coupled device (CCD) image sensor provides, in accordance with a television standard, horizontal and vertical CCD control signals to obtain a purely sequential mode of operation on the one hand, and alternatively a modified mode of operation to permit image signals to be viewed directly on a standard viewfinder display. The apparatus includes a frequency generator, a standard timing generator, a pixel clock generator, and a small number of additional timers and logic units which are driven by signals from the generators to selectably generate the vertical and horizontal CCD control signals for the alternate modes of operation. The method includes generating a plurality of precisely timed pulses referenced to television standard synchronizing and control signals, and logically combining these pulses and standard signals to generate the vertical and horizontal CCD control signals.Type: GrantFiled: January 15, 1993Date of Patent: June 14, 1994Assignee: Eastman Kodak CompanyInventor: Ram Kannegundla

Patent number: 5315387Abstract: A horizontal synchronization circuit uses a standard decoder to generate a stable first signal locked in frequency and phase to horizontal synchronizing pulses in a composite video signal. A waveshaping circuit reshapes the first signal to generate a second signal for input to a synchronizing circuit. The synchronizing circuit generates a higher-frequency third signal. A timing generator divides the frequency of the third signal to generate a fourth signal having the same frequency as the first and second signals, and a fifth signal having a higher frequency. The fourth signal is fed back to the synchronizing circuit, and can also be used for synchronization of video signal processing. The fifth signal can be used for horizontal scanning at a rate higher than the standard horizontal frequency.Type: GrantFiled: January 21, 1993Date of Patent: May 24, 1994Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Miyuki Tachibana
