IPC: H04N5/44
Filed: 1990-03-29
Abstract: PURPOSE:To improve the quality of the screen by detecting production of ghost disturbance so as to display a video image before the occurrence of disturbance. CONSTITUTION:A ghost fluctuation detection circuit 8 compares a phase of a horizontal synchronizing signal separated from a received video signal with a phase of a reference signal of a horizontal period, obtains a phase error and outputs a ghost fluctuation signal representing the fluctuation of a time axis of the horizontal synchronizing signal. A control means 7 discriminates it as the production of a picture fluctuation of a picture and disturbance due to ghost to output a display control signal when the ghost fluctuation signal reaches a prescribed threshold level or over. A video signal before a display control signal is outputted is stored in a memory means of the display control means 3 and the display control means 3 reads the video signal stored in the memory means by the input of the display control signal and gives it to a display device. Thus, an excellent picture is displayed and the quality of the pattern is improved.

Abstract: PURPOSE:To make it possible to perform high-sensitivity detection of long- wavelength infrared light, by providing a same-conducting-type mixed crystal film, which is formed on a one-conducting type Si crystal substrate, and providing a conducting film, which is formed on said mixed crystal film. CONSTITUTION:An n-type Ge crystal film 2 is formed on an n-type Si crystal substrate 1. An n-type Si crystal film 3 is formed on the n-type Ge crystal film 2. A specified forward bias voltage is applied between the substrate 1 and the crystal film 3 for only a specified time so that the substrate 1 or the crystal film 3 becomes the positive side with respect to the crystal layer 2. Electrons of specified amount are injected in a potential well, which is formed in the conduction band of the crystal film 2. Thereafter, a reverse bias voltage is applied between the substrate 1 and the crystal film 3. Then the elections, which are injected in the potential well formed in the conduction band of the crystal film 2, are confined. When infrared light is projected on the confined electrons, the electrons absorb the light and the excited state is obtained. When the energy of the quantum of the infrared light is larger than a discontinous energy value EC, the energy moves to the conduction band of the crystal film 3. Thus the detection of the long-wavelength infrared rays can be carried out.
