Title: Camera capable of detecting difference in posture
Inventor: TSUKAHARA DAIKI
IPC: G03B5/00
Filed: 1993-12-28
Abstract: PURPOSE:To simplify the structure of a posture difference detecting device and to miniaturize a camera by providing a posture difference calculating means calculating the posture of a camera main body for every interval at a unit-time and calculating a difference in the posture of the camera main body. CONSTITUTION:A horizontal direction sensor 12A detecting a change in the posture in a horizontal direction and a posture detecting sensor 12B detecting the change in the posture in a vertical direction are incorporated and when the camera 24 is inclined by an inclination angle theta1, the posture detecting sensor 12 incorporated in the camera 24 is inclined by the inclination angle theta1 as well. Therefore, reaction force generated on a pressure sensitive sheet 22 becomes reaction force N1' at a contact point 14 and reaction force N2' at a contact point 15 and the reaction force corresponding to the inclination angle is generated on the pressure sensitive sheet 22 at respective contact points 14 and 15. The reaction forces generated at respective contact points 14 and 15 are sequentially inputted to a CPU from the sheet 22 of the posture detecting sensor 12B every specified time and the inclination angle theta1 of the camera is calculated based on the inputted reaction forces N1' and N2'. The inclination angle alpha1 can be easily obtained from the difference between the reaction forces N1' and N2' by a proportional calculation.

Title: Transmission circuit
Inventor: KIRISAWA AKIHIRO
IPC: H04B1/04
Filed: 1998-12-11
Abstract: PROBLEM TO BE SOLVED: To provide a transmission circuit from which an ON/OFF ratio higher than that of a conventional circuit can be obtained without increasing the size and the cost. SOLUTION: A modulator 1 modulates a data signal, a mixer 2 mixes the modulated signal with a local signal from a synthesizer 7, a band-pass filter 3 eliminates a local leak component and an image signal, the resulting signal passes through an RF switch 4 and amplified by a power amplifier 5. The amplified signal is emitted to space through an antenna 6. In the case of usual transmission, a selector 8 selects a data signal ϕ1 for the modulator 1. In this case, the RF switch 4 is closed. In the case of burst-off, the modulator 1 receives the data signal ϕ2 selected by the selector 8. This signal is far higher in speed than actual transmission data. Furthermore, in this case, the RF switch 4 is controlled open.

Abstract: PROBLEM TO BE SOLVED: To provide a color picture processing method which can remove an offset from a color original which is perfect-pressed by using only picture information on one face of paper without depending on a special input device. SOLUTION: The resolution of an input color picture is reduced (S2) and a color coordinate system is converted into that with high independence (S3). Edge strength is calculated (S4) and an edge is detected by a binarization processing (S5).

An edge difference picture is generated from the edge strength of an original picture and the offset removal picture (S9) and a part where the picture is deteriorated due to an inappropriate processing is detected. A processing scale (window size) is reduced and the processing is executed again at the periphery of the part (S11 and S12).  The offset part is identified by the difference calculation of the offset removal picture and the reduced original picture (S13), the offset part in the original picture with original resolution is removed (S14) and the picture is outputted (S15).
