摘要： Disclosed is a solid-state imaging device wherein optical information of a number of photo-electric conversion elements arranged in a matrix is read into vertical signal lines by a vertical shift register and then the optical information on the vertical signal lines is horizontally scanned by a horizontal register of a charge transfer device. Bias charge storage means and quasi-signal sweep-out drains are disposed between the horizontal register and the vertical signal lines, and a bias charge input means is arranged in the horizontal register. In order to ensure high efficiency in transferring signals between the vertical lines to the storage means, the sweep-out drains and the charge transfer device, it is arranged for bias charges to be provided at each stage of transfer. Thus, bias charges supplied from the storage means are used to transfer charges from the vertical lines to the storage means. Similarly bias charges directly injected from the quasi-signal sweep-out drains are used to sweep out quasi-signals from the storage means to the quasi-signal sweep-out drains. Finally bias charges supplied from the bias charge input means of the charge transfer device are used to read signals from the storage means into the charge transfer device. By virtue of this, the sweep-out efficiency of the quasi-signals from the capacitances which supply the bias charges and a read-out efficiency of the signal charges are enhanced and a high quality of video signal is produced.

摘要： A picture-in-picture television receiver is disclosed in which a television picture to be inset is compressed at a compression rate of 1/n and inset as a small-picture in part of a main television picture or large picture, and a single field memory for small-picture reproduction is provided therein in or from which a video signal can be randomly read and written line by line as a unit. In the single field memory is stored the small-picture video signal line by line by the application of a writing clock in which case the time taken in the writing is less than 1/(n+1) of a horizontal period. Then, from the memory is read the stored small-picture information by the application of a reading clock of n times the frequency of the writing clock during the time that writing is not performed, and supplied to be inset in the main television picture. A small-capacity buffer memory is provided at the prestage or following stage of the field memory to prevent the read/write timing overlap in the field memory irrespective of whether the small-picture and the main television picture are synchronized or not in the transmission systems. Thus, the capacity of the field memory essential for the small-picture is about a half of the conventional one.
