Title: Fifo read control circuit
Inventor: KOZU YUHEI
IPC: G06F5/14
Filed: 1985-08-19
Abstract: PURPOSE:To decrease the quantity of hardware by counting number of stages of data written in a data register and starting consecutive read of a data from the data register when the number reaches a preset value not causing overrun. CONSTITUTION:A data number l-bit stored in a mask bit register 8 until read is started from a read terminal is set to '0' and the remaining n-l-bit is set to '1'. While a data from a FIFO write circuit 4 is being transferred to a data register 2, a read ready signal control circuit 9 detects always a use bit of each stage and a value of a mask bit corresponding thereto. When the product as to all stages of FIFO 1 for the OR of the both goes to '1', a read ready signal 7 is made active and the presence of n-set of read data in the FIFO 1 is informed to a FIFO read circuit 5 to read sequentially the data. Even when a data is sent to the FIFO 1 at a constant transfer speed, no overrun takes pace and the consecutive read of the n-set of data is realized by n-set of FIFOs.

Title: White balance adjuster
Inventor: OSAWA IKUO
IPC: H04N9/73
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To reduce the number of elements of an input circuit and a decision circuit and to reduce the number of IC pins by generating a control signal for white balance adjustment on the basis of an output signal of a comparator and adjusting a DC level and an AC level of each primary color signal of RGB. SOLUTION: A comparator 8 performs level comparison between a voltage which is voltage converted by a first and a second resistances 1 and 5 and a generation voltage. Thus, the comparator 8 can perform precise discrimination and generates a decision output signal at an 'H' level or an 'L' level. Also, in this case, signals are latched by latch circuits 70 to 72 in the same way as at the time of cutoff adjustment and are impressed to a microcomputer 5 through a bus interface circuit 74. The microcomputer 75 decides and adjusts a gain (an alternating current level) of AC adjustment circuits 18 to 20. Thus, it is possible to process the cutoff adjustment and drive adjustment at an input circuit and a discrimination circuit by using the comparator 8 or the like.
