Title: Stereoscopic display device
Inventor: OSAWA HIROSHI
IPC: G03B35/26
Filed: 1987-10-05
Abstract: PURPOSE:To attain simultaneous observation with a number of persons by synthesizing the display of right and left images to be arranged on the same display screen with a reflecting mirror and executing the stereoscopic vision of the synthesized display through a glasses to have a polarizing characteristic. CONSTITUTION:The left image is reflected by a half transmitting mirror 7 and reaches a polarizing filter 8 to be set in front of an observer. Then, for the right image, the image is reflected by a full-reflecting mirror 6 and enlarged by a lens 9. For the lens 9, since the sizes of the right and left images are different by the difference of the optical path length of the right and left images at the time of reaching to the observer, this difference is corrected and the right image, which passes through this lens 9, passes through the half transmitting mirror 7 and reaches the polarizing filter 8. The left image passes through a polarizing filter 5 and a filter 11 which has the same polarizing characteristic as the polarizing filter 5, and reaches the eye of the observer. On the other hand, the right image passes through filters 4 and 8 and reaches the eye in the same way as the left image, however, it can not pass through the filter 11. Thus, the right and left images are synthesized and observed by the full- reflecting mirror 6 and the half reflecting mirror 7.

Title: Signal transmitting means between camera body and accessory
Inventor: ANDO HIROKAZU
IPC: G03B17/02
Filed: 1984-11-27
Abstract: PURPOSE:To eliminate the need for a metallic contact by providing a light emitting element at a desired position of a camera body, and providing accessaries such as a data back and a winder with a photodetecting element which faces said light emitting element when they are attached to the camera body. CONSTITUTION:A light emitting element L1 such as an LED which emits light associatively with the operation of an X contact is provided at a data back fitting position of the camera body 1, and a photodetecting element L2 such as a phototransistor is arranged at the data back side opposite said light emitting element L1. When the accessary needs to be driven, the light emitting element of the camera body side is turned on and its light is received as a driving signal by the photodetecting element of the accessary side to drive the accessary. This constitution eliminates the need to set the light emitting element and photodetecting element precisely opposite each other as compared with the use of metallic contacts, so the fitting precision may be rough; and the use of the light emitting element and photodetecting element eliminates the need for a contact, so it is not necessary to consider an increase in contact resistance and the staining of contact surfaces which are caused frequently when metallic contacts are used.

Title: Automatic hue correction circuit
Inventor: MIYAMOTO YOSHITOSHI
IPC: H04N9/64
Filed: 1991-09-30
Abstract: PURPOSE:To attain stable skin color correction by fixing a correction operation range. CONSTITUTION:An output +I of an I demodulator 1 is given to a comparator 32, outputs +Q, -Q from a Q demodulator 6 are rectified at their full waves by a full wave rectifier circuit 35 and then a rectified output is given to the comparator 32. The comparator 32 compares the modulated output I with the full wave rectified output ¦Q¦. When the output I is larger than the output ¦Q¦, a phase is included within the range of I axis + or -45 deg. independently of the level of an input chroma signal. In this case, the comparator 32 drives a buffer circuit 37 and turns an output terminal to low impedance. The output terminal of the Q demodulator 6 is connected to the output terminal of the circuit 37 through resistors R11, R12, and when the output terminal of the circuit 37 is turned to the low impedance, attenuated demodulation output +Q appears on the node between the resistors R11, R12 and supplied to a color difference matrix circuit 5. Thus the fixed correction operation range can be obtained independently of the level of an input chroma signal.
