Filed: 1986-08-15
Abstract: PURPOSE:To enable driving of many display segments under matrix type electrode display by interposing a thin film consisting of a 2nd oxidation-reducing material between an electrode substrate and electrochromic thin film. CONSTITUTION:The oxidation-reduction reaction of a display device utilizing the discoloration arising from the oxidation-reduction reaction of oxidation reducing materials is induced by the transfer and acceptance of electrons which take place with the 2nd oxidation reducing material. More specifically, the thin film of said 2nd oxidation reducing material is required to have two oxidation-reduction levels above and below the oxidation-reduction electron level relating to the discoloration of the electrochromic material film provided in contact with one surface thereof. The electrons are injected into the upper electron level when the potential impressed to the electrode substrate is swept in a negative direction and attains said electron level. As a result, the 2nd oxidation reducing thin film is subjected to the reduction to reduce and discolor the electrochromic material. The restoration of the colored state to the original state is executed by sweeping the potential impressed to the electrode substrate backward in the positive direction so that the potential lowers below the lower level of the 2nd oxidation reducing thin film.

Filed: 1992-07-20
Abstract: PURPOSE:To quickly detect a moving quantity of a camera by sending a control signal representing a direction of camera movement and its amplitude to a picture coding section and suppressing a picture data output when the signal is received. CONSTITUTION:When the direction of a camera 10 is changed, a camera control section 1 sends a control signal representing a direction of camera movement and its amplitude, the direction is changed by the amplitude and the control signal is inputted to a control section 3-1 of a picture coding section 2. Then a picture signal from the camera 10 is sampled by a sampling section of a coding section 2 implementing coding in matching with a characteristic of picture data. Furthermore, the sampled picture data are quantized by a quantization section 8, and a coding section 9 finds out the characteristic of picture data and encodes the data by an optimum method and outputs the result. In this case, the control section 3-1 suppresses the picture data output while the section 3-1 receives the control signal from the control section 1 and reduce the size of the picture data sampled by the sampling section 7 by increasing the quantization step of the quantization section 8. Then the moving quantity is quickly detected even when the direction of the camera 10 is changed.
