Title: Picture processor
Inventor: IIIZUMI TOMOO
IPC: G06F12/06
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To reduce an access time to a memory for operating 0 clear by simultaneously writing 0 in interleaved memories in the case of 0 clearing a memory to which access is performed in an interleave system. SOLUTION: In the case of 0 clearing an RAM 1 and an RAM 2, a CAS1n signal and a CAS2n signal are simultaneously turned into a low active state so that the CASn of the RAM 1 and the RAM 2 can be simultaneously turned active. At the same time, three state buffers 10 and 11 are simultaneously turned into a buffer state by a write enable signal. In this state, only a CLR signal (0 clear data) is simultaneously written through an invertor 12, AND gate 9, and two three state buffers 10 and 11 in the two RAM 1 and 2 without applying the 0 clear data to a data bus. Thus, a time required for 0 clear can be reduced by simultaneous writing in the RAM 1 and the RAM 2 with only 5 clocks.

Title: Driving method for image sensor
Inventor: SAKASAI KAZUHIRO
IPC: H04N5/3745
Filed: 1994-08-12
Abstract: PURPOSE:To provide a driving method for image sensor which prevents the occurrence of after-image without reducing the read speed by making the conduction time of a thin film transistor TR for reset longer than that or a thin film TR for electric charge transfer. CONSTITUTION:When a MOS TR 19 is turned off, the source potential of a first thin film TR TT is set to the reference potential, and it is detected by an IC 15 for driving; and as the result, the difference from the potential detected by the IC 15 for driving is outputted as the final sensor output when the first thin film TR TT is first turned off. Consequently, the size of a second thin film TR TR for reset is made smaller than that of the first thin film TR TT for electric charge transfer to obtain the constitution where the offset voltage is zero. Meanwhile, the conduction time of the second thin film TR TR is made longer than that of the first thin film TR TT to secure the time sufficient for reset, thereby preventing the occurrence of after-image.

Abstract: PURPOSE:To facilitate the frame constitution in common to various systems, to allow the system to easily cope with frequency design changes, to improve a data transmission efficiency and to reduce power consumption by providing 3 kinds of transmission signals whose level differs. CONSTITUTION:When an NRZ (non return-to-zero) code of binary logic is changed into a ternary logic, a level 2 is used for logic 1 and a level 1 is used for logic 0 and a level 0 is used for 'don't care', that is, a code representing no data change or 'not definite'. Then a data portion not requiring data change for a reception side is sent as a level 0 code from a sender side. Moreover, when a data at the receiver side requires a change, such as change into logic 1 from logic 0 a code of level 2 is sent from the sender side and only the revision part of the data is changed from logic 0 into logic 1. Thus, the data transmission efficiency is improved, low power consumption is attained and the system copes easily with frequency design change and the frame constitution in common to the system is facilitated.
