Abstract: PROBLEM TO BE SOLVED: To simultaneously display a picked-up image of a variable frame rate and an image whose frame rate is different from that of the picked-up image.
SOLUTION: An image signal DVb of a variable frame rate picked-up image is generated by an image signal generating unit 11 of an imaging apparatus, and a synchronizing signal to be used for generating the image signal DVb is generated by a synchronizing signal generating unit 18. When an image signal DVr is supplied from control equipment or the like, the synchronizing signal generating unit 18 is brought into self-running state. Even when the frame rate of the image signal DVr is different from the frame rate of the image signal DVb, the image signal DVb and the image signal DVr of the different frame rates can be output from the imaging apparatus as monitor image signals VFout, MTout. When a reference synchronizing signal SYref is supplied in place of the image signal DVr, the synchronizing signal generating unit 18 of the imaging apparatus operates synchronously with the reference synchronizing signal SYref, thereby outputting the image signal DVb synchronized to the reference synchronizing signal SYref.

Abstract: PURPOSE:To prevent image distortion without using any expensive lens by storing an output from a CCD when there is no deviation in the arrangement when the light of a film image is optically deviated or not deviated by a selecting means. CONSTITUTION:Under the control of a CPU 34, a film driving circuit 37 intermittently scrapes off a film 14. On the other hand, a shutter driving circuit 38 drives a shutter 17 under the control of the CPU 34. During a telecine converting term after the film 14 is scraped off, a shutter 27 is twice opened, and CCD 23r, 25g and 27b are twice exposed. During the latter half of this term, an optical axis is shifted for a 1/2 pitch. Therefore, the respective outputs of the CCD become the output for which the optical axis is not shifted and the output for which the optical axis is shifted. Those outputs are written in a frame memory 29 and continuously written in a frame 30. Then, while it is written in one frame memory, the output is read from the other frame memory.

Abstract: PURPOSE:To process a video signal and a fluctuated black level signal separately by subtracting a low frequency fluctuation component from an input signal, converting the result into a digital signal and then adding the fluctuating component to the converted signal. CONSTITUTION:An input signal comprising a video signal and a black level signal is fed from an input terminal 1 to a subtractor 5/ the subtractor 5 subtracts the black level fluctuation component to provide an output of the video signal only. The video signal is fed to a 10-bit A/D converter 7 via a buffer 6 and converted into a digital video signal. Then a nonlinear processing circuit 11 executes stable nonlinear processing. Furthermore, the black level fluctuation component is subtracted by the subtractor 5 of an analog region and added in the digital region. Thus, the video signal and the black level fluctuation component are processed separately and since the converter 7 converts only the video signal into a digital signal, the input signal is processed with simple configuration.

Abstract: PROBLEM TO BE SOLVED: To remove any fixed pattern noise without being affected by any signal component due to photoelectric conversion.
SOLUTION: Charge acquired by photoelectric conversion with two-dimensionally arranged photoelectric conversion elements 121 is transferred to a vertical direction by a vertical transfer part 122. A horizontal transfer part 124 successively transfers charge transferred in the vertical direction by the vertical transfer part 122 to a horizontal direction, and converts it into an imaging signal. A correction signal is generated by using an imaging signal Sa generated by the horizontal transfer part 124, and the imaging signal to be output from the horizontal transfer part 124 is corrected according to the correction signal. A driving part 125 stops the transfer of charge from the vertical transfer part 122 to the horizontal transfer part 124 by a transfer control gate part 123. The correction signal is generated by using the imaging signal Sa to be output from the horizontal transfer part 124 when the charge transfer from the vertical transfer part 122 to the horizontal transfer part 124 is stopped.

Abstract: PROBLEM TO BE SOLVED: To display an imaged image with a variable frame rate and an image whose frame rate differs from that of the imaged image, at the same time. SOLUTION: An image signal generating section 11 of the imaging apparatus generates an image signal DVb of a variable speed frame rate imaged image, and a synchronizing signal generating section 18 generates a synchronizing signal used for production of the image signal DVb. When the imaging apparatus receives an image signal DVr from a control apparatus or the like, the imaging apparatus brings the synchronizing signal generating section 18 into a self-running state. Even when a frame rate of the image signal DVr differs from a frame rate of the image signal DVb, the imaging apparatus outputs the image signals DVb and DVr whose frame rates differ from each other as monitor image signals VFout and MTout. When the imaging apparatus receives a reference synchronizing signal SYref in place of the image signal DVr, since the synchronizing signal generating section 18 of the imaging apparatus is operated synchronously with the reference synchronizing signal SYref, the imaging apparatus outputs the image signal DVb synchronously with the reference synchronizing signal SYref.
