METHOD OF CONTROLLING SENSITIVITY OF A TELEVISION CAMERA ON A CCD MATRIX AND REPRODUCING ITS VIDEO SIGNAL IN A MOBILE DEVICE IN CONDITIONS OF HIGH ILLUMINATION AND / OR COMPLEX BRIGHTNESS OF OBJECTS

摘要

FIELD: television technology.;SUBSTANCE: invention relates to television equipment and is intended for use in television cameras made on the basis of matrix television sensors based on the technology of charge coupled devices (CCD), in which electronic sensitivity adjustment is provided by changing intraframe accumulation time. Sensor accumulation section is divided horizontally into n targets isolated from each other with the same format, which have parallel control of photo reception and scanning processes, wherein the output register is made in the form of two adjacent linear registers acting alternately on the first two-channel DCCD in one direction or on the second two-channel DCCD in the opposite direction, wherein each of these linear registers comprises half the elements of the number of pixels for each photodetector row, and in interval τ_o.h.c. loaded with charge packets of current information line both linear registers in series in time and separately for odd and even pixels of this line, and number of phase electrodes for separate pixel in both linear registers shall be even, making indicator 2 or 4. Playback of video signal of television camera is carried out on video monitor, which together with camera is integrated into mobile device, for example, as it is made in mobile telephone.;EFFECT: technical result is arrangement in mobile device of automatic mode of increasing sensitivity for fragments of television frame, which are observed at low illumination (brightness) of corresponding objects by increasing accumulation time for them and with possibility of correct selection of their spatial position, as well as simultaneous implementation of saving power consumption of photodetector.;1 cl, 10 dwg
