Abstract: A logic LSI has a plurality of modules such as a CPU contained in one chip. Frequency changing conditions, signals for designating modules whose frequencies are changed for each frequency changing condition, and signals for designating frequencies to be changed are stored in a storage device of a frequency controller, software-wise.

Each of the modules generates a plurality of internal clocks in synchronization with the basic clock and selects one out of the internal clocks according to the frequency changing signal.

Abstract: A high resolution solid-state color imaging apparatus having two-dimensionally disposed photoelectric sensors are arranged in rows and columns each having a color spectral responsivity characteristic such as by employing color filters. Each of the photoelectric sensors is scanned so as to obtain an intensity signal with respect to each row of each field, and wherein scanning of each field is for the same number of rows as that of each frame. Intensity signals are obtained only by the scanned output of each row. Additional intensity signals equal to half the number of said first mentioned intensity signals are obtained by a 2:1 subsampling of bandwidth-restricted signals by a filter along the vertical temporal frequency, thereby realizing high vertical resolution by the photoelectric image sensors of conventional row numbers and having compatibility with a conventional NTSC system and, furthermore, eliminating aliasing distortion.

Abstract: According to the present invention, the number of elements of a signal processing circuit or the like can be drastically reduced by conducting a time-multiplex processing. In a transversal filter having a coefficient of symmetry of 16 taps, for example, the prior art requires about 58,000 transistors. In case four signal processing cores (i.e., SPC) having a function of four taps are used, the number of transistors required can be reduced to about 34,000 by a duplexing process. In case two SPCs having a function of eight taps are used, the number can be reduced to about 19,000 by a quadplexing process. In case, moreover, one SPC having a function of sixteen taps is used, the number can be reduced to about 13,000 by an octaplexing process. Here, the reason why the number of elements is not halved even if the number of the SPCs is halved is that the number of elements to be used in control circuits, memories and so on increases.

The solid-state imaging device according to this invention has a transfer MOST provided between a vertical signal output line and a horizontal switch MOST, a resetting MOST connected to the junction between said transfer MOST and the horizontal switch MOST, and a mechanism for setting the vertical signal line at a reference potential just before signal transfer.

Therefore, the charges under the gate of the transfer MOST can be removed for fixed noise to be greatly reduced.
