Filed: 1989-06-14
Abstract: PURPOSE:To improve the visual picture of an object picture by providing at least one filter, a selector and a frequency analyzer, analyzing a frequency component of an input signal and eliminating the frequency component not almost included in the input signal. CONSTITUTION:An input signal 1 is converted into a filter output 3 subject to frequency conversion and inputted also to a frequency analyzer 4. The frequency analyzer 4 measures the local frequency distribution of the input signal 1 and outputs a control signal 5 commanding a selector 6 to select the filter output 3 when a frequency having a large distribution passes and a frequency with a small distribution is blocked. Means when the band of the local frequency of the input signal 1 is sufficiently large, the selector 6 is switched to output the input signal 1 as it is. The frequency having a small frequency distribution is almost quantized distortion and coded distortion and the deterioration in the picture quality by the adaptive filter is not almost caused.

Title: Rapid start type fluorescent lamp
Inventor: YAMAMOTO RIKIO
IPC: H01J61/35
Filed: 1996-06-13
Abstract: PROBLEM TO BE SOLVED: To provide a rapid start type fluorescent lamp, which can remarkably restrict the generation of black dots, by including yttrium (Y) in a transparent conductive film, which is formed in the inner surface of a glass tube and which is mainly composed of tin (Sn). SOLUTION: In this rapid start type fluorescent lamp, a transparent conductive coating film 2 mainly composed of tin (Sn), a metal oxide coating film 3 and a phosphor coating film 4 are formed in order on the inner surface of a glass tube 1. Two or more kinds of dopant, which include yttrium (Y), are added in the transparent conductive coating film 2. Concentration of yttrium (Y) in the transparent conductive coating film 2 is preferably set at 0.20-0.97 (mol%) in relation to tin (Sn). Since Y has a high affinity with sodium (Na), when Na in the glass tube 1 is passing through the transparent conductive coating film 2, Y traps Na, and Na is hard to be diffused to a phosphor layer.

IPC: H04N5/341
Filed: 1989-06-15
Abstract: PURPOSE:To prevent the deterioration of a video signal by taking an exposure time of an image pickup element longer than that at usual state in the case of deficient illuminance and sending the obtained video signal. CONSTITUTION:When a microcomputer 6 judges it that the illuminance at pickup location is not sufficient, a control signal is sent to a CCD drier circuit 5, and the CCD driver circuit 5 sends a control signal to the CCD 1 so that the charge is not transferred from an exposure section to a vertical transfer section in the cycle of succeeding 1/60sec after the end of a cycle of 1/60, but transferred from the vertical transfer section to the horizontal transfer section. Light is kept radiating to the exposure section, which accumulates the charge. Then the control signal is sent so that the similar video signal is sent to that at normal state in the cycle of succeeding 1/60sec. The video signal sent from the CCD 1 is stored in a memory 8. A selector circuit 4 selects a video signal in the encoder 3 in an odd number field and a storage signal of a memory 8 in an even number field.

Abstract: PURPOSE:To automatically perform a due operation at the highest speed by selecting the optimum number of weights in response to the working conditions of a microprocessor application circuit. CONSTITUTION:Some of address signals 2 supplied from a microprocessor 1 are applied to a storage 3 with other signals 2 applied to an address decoder 4 respectively. Some of outputs of the decoder 4 are applied to the storage 3 for selection of necessary devices.

Thus a weight number counter circuit 6 works in parallel to above process of the decoder 4 and counts the weights set from the weight request detecting timing of the processor 1. The selected storage 3 outputs the data into a bus 9 after its proper timing, and a data decision detecting circuit 8 monitors the bus 9 to detect the decision of data. A weight control circuit 5 outputs the weight requests to the processor 1 until the detection output of the circuit 8 is obtained. The circuit 6 stores the counting result in the circuit 7. In such a constitution, a due operation is automatically carried out at the highest speed.
