IPC: G02F1/133
Filed: 1994-01-17
Abstract: PURPOSE:To improve efficiency in a battery-using voltage region by controlling the set control output voltage of a liquid crystal backlight inverter to a predetermined value via a converter which works to raise and lower voltage. CONSTITUTION:A lamp 22 is driven via a DC power source 21, a voltage raising/lowering DC-DC converter 14, and an inverter 13.

Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To make it possible to change a secondary battery built in a portable apparatus with good efficiency even in a state that a commercial power supply is not supplied. SOLUTION: When it is detected that the terminal of a portable apparatus is brought into contact with a charging terminal 5, a main control part 8 controls a data transmission-reception part 6 so as to communicate with the portable apparatus. Data which expresses the consumption energy of a secondary battery built in the portable apparatus is received. A charging amount required for completely charging the secondary battery built in the portable apparatus is found on the basis of the consumption energy. A current amount Ia and the charging time Ta which correspond to the charging amount are computed. A second charging control part 4 is controlled. Eelectric power in the current amount Ia is taken out from a secondary battery 3 so as to be supplied to the charging terminal 5. Thereby, a charging operation to the secondary battery built in the portable apparatus is started.  Then, when the computed charging time Ta elapses after the start of a charging operation by the secondary battery 3, the main control part 8 controls the second charging control part 4 so as to prohibit electric power from being taken out from the secondary battery 3, and the charging operation to the secondary battery built in the portable apparatus is finished.

Title: Feature extraction device
Inventor: RYU TSUGUAKI
IPC: G06K9/46
Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a feature extraction device capable of improving the accuracy of sorting characters into a similar characters category. SOLUTION: A character image of one character is read out from an external storage device 1 and stored in memories 2, 3. A horizontal division part 5 in an area division part 4 divides the character image stored in the memory 2 into M sections in a horizontal direction. A longitudinal division part 6 divides the character image stored in the memory 3 into N sections in a longitudinal direction. On the other hand, a scanning range limitation part 7 sets up a scanning range to 1/P of the width of the character and 1/Q of the height of the character. A feature extraction part 8 scans each section divided by the division part 4 within a range limited by the limitation part 7, counts up the number of pixels reached up to an initial character and outputs a feature value based on the count value.  Since the scanning range is limited, a feature value independent of the internal structure of a character can be obtained and the sorting of the character into a category of similar characters can be accurately executed.

Title: Focus detector
Inventor: AKASHI AKIRA
IPC: H04N5/335
Filed: 1987-01-12
Abstract: PURPOSE:To perform invariably correct focus detection by preparing plural AGC areas of a sensor array end setting the AGC area of the best sensor when the range of a sensor output as an object of focus detection processing is varied. CONSTITUTION:In a figure, ST1, ST2, and ST3 are light measuring elements for AGC and signals AGC are outputted through a converter amplifier AAMP. A light image formed on the sensor array SAA is formed on the ST1, ST2, and ST3 as well. Then MOS1 and MOS2 are MOS transistors (TR) for switching the outputs of the light measuring elements ST1 and ST3 to enable entire-area AGC when a signal CAGC is at 'H' or center part AGC when at 'C'. If the signal output has a maximum value outside the center AGC range, the signal CAGC is held at 'H' and if the signal output has the maximum value in the center AGC range, the signal CAGC is held at 'L'. Consequently, a proper photoelectric conversion signal is obtained.

Filed: 1983-01-14
Abstract: PURPOSE:To prolong the life of whole device by providing a temperature sensor a little to the wind inlet side from the center of a fluorescent lamp. CONSTITUTION:A micro-light shutter array 1 consisting of a liquid crystal device etc. is illuminated by a fluorescent lamp 2. A luminance sensor 3 feeds back brightness of the fluorescent lamp to a luminance controller 4. A blasting fan 5 can make hot air by a heater 6. A sealing section 9 restricts the extent of air flow and serves as heat insulator. A temperature sensor 7 is placed a little to the wind inlet side from the center of the fluorescent lamp. Accordingly, the wind inlet side can be kept at initially set temperature even when aging of the fluorescent lamp 2 advances and self-heat generation of the lamp 2 increases. The wind outlet side becomes high temperature due to addition of self generated heat. However, the drop of light emitting efficiency of the fluorescent lamp is slower when the temperature is above optimum tube wall temperature than the case when it is below the said temperature.
