Abstract: A reproducing apparatus for a recording medium recorded with compressed image data, audio data relating to musical accompaniment, character data relating to musical accompaniment, data showing the musical accompaniment scale, scale data for a scale change position and a position after a scale change and data showing a time passage relating to an audio signal relating to the musical accompaniment has an image reproducing unit, a reproducing unit, a signal generating unit and a mixer. The image reproducing unit decodes and reproduces image data read-out from the recording medium. The reproducing unit reproduces audio signals relating to musical accompaniment, character data and data displaying a scale from the recording medium. The signal generating unit generates a harmony signal for the audio signal outputted from the microphone based on data displaying the scale played back by the playback part. The mixer mixes and outputs the audio signal outputted from the microphone, the audio signal reproduced by the reproducing unit and the harmony signal from the signal generating unit.

Abstract: A projection-type display device for producing a synthesized symmetrical projected image. The device includes three liquid crystal light valves associated with the three primary colors producing three separate images. One of the light valves is horizontally scanned in a direction opposite to the horizontal scanning direction of the other two light valves. The two images produced by the light valves which scan in the same horizontal direction are mirror images of the image produced by the third light valve.

Abstract: A projection-type display device for producing a well balanced color image without the use of a neutral density filter. The device includes three liquid crystal light valves associated with the three primary colors and two dichroic mirrors. A light source generates colored light. The optical length between the light source and the light valve associated with the primary color of the colored light having the highest level of luminous intensity is greater than the optical lengths between the light source and each of the other two light valves. One of the three liquid crystal light valves is driven by circuitry to produce an image which is a mirror image of the images produced by the other two light valves.

Abstract: A solid-state image sensing apparatus employs normally-ON type static induction transistors to constitute picture elements. Some of the picture elements are shielded from light so as to serve as light-shielded picture elements. The apparatus is provided with an automatic control loop which controls the voltage level of each of the row selecting signals in accordance with the output of the corresponding light-shielded picture element, whereby the voltage level of each row selecting signal is automatically controlled in such a manner that the output of the corresponding light-shielded picture element becomes zero. Thus, it is possible to obtain a video output which includes no offset nor dark output without decreasing the dynamic range.

Abstract: Method for detecting a focus condition of an imaging optical system by using a surface acoustic wave device is disclosed. A light receiving element array formed by a plurality of light receiving elements receives a light flux transmitted through at least a part of an image formed by the imaging optical system. Then, outputs of said light receiving elements are processed on real time by means of a Fourier transform device including a surface acoustic wave device, a convolver, etc. so as to derive an image sharpness and/or an image lateral shift, both of which are used for a focus detection. Therefore, as compared with a conventional focus detection method, it is possible to perform the focus detection in a fast and accurate manner by a simple and small construction.

Abstract: In a method and apparatus for detecting focus condition of an imaging optical system, the focus condition is detected in accordance with a combination of two different detection methods such as an image sharpness detection and an image lateral shift detection by using first and second light receiving element arrays for the image sharpness detection and a third light receiving element array for the image lateral shift detection. For making the construction of the apparatus compact and simple, these light receiving element arrays are formed on the same semiconductor substrate. Further a light flux dividing prism and a lenticular lens array are formed integrally with each other. According to the focus detection method of the present invention, it is possible to detect the focus condition for various kinds of subjects accurately over a wide range by using both the image sharpness detection and image lateral shift detection even in a range near an in-focus position.

Abstract: A focus condition of an objective lens is detected on the basis of a lateral shift of two images formed by first and second light fluxes which are transmitted through right- and left-hand halves of the lens, respectively. In order to separate the first and second light fluxes, there is arranged an array of triangle prisms each having first and second surfaces which are inclined symmetrically with respect to the optical axis of lens by a critical angle so that one of the light fluxes is transmitted through the one of the surfaces, but is totally reflected by the other surface of each prism. The first and second light fluxes transmitted through the prisms are received by an array of light receiving elements in such a manner that the first and second light fluxes are selectively received by odd and even numbered light receiving elements, respectively.
