A motor itself has multi-functions to be able to drive a plurality of objects to be controlled, so that the whole apparatus is compact and provided at low cost. The rotation planes of first and second rotating units B1 and B2 are faced with each other to make these planes in a mutually pressed state. A current is supplied to a piezoelectric element provided on the rotation plane of any one or both of the first and second rotating units, and the rotation of any one of the first and second rotating units is selectively stopped by pressing members, so that any one of the rotating units can be selectively rotated.

A plurality of shutter times are set to an image pickup device and an image is taken in a way to separate an incident light amount range into a low and a high luminance and, through the signal processing, it is possible to take an image over a wider dark to bright light amount range and, in particular, obtain a better color reproduction over a wider luminance range. In the case where an (R-Y) signal and (B-Y) signal are processed with a low-speed and high-speed shutter signal obtained and the high-speed shutter signal is subjected to logarithmic conversion and a bias signal is applied to provide a continuity with the low-speed shutter signal, processing is performed on a comparing section, characteristic conversion section and calculating section so that a greater one of the (R-Y) and (B-Y) signals is subjected to logarithmic conversion and the other signal is subjected to characteristic conversion in accordance with a value corresponding to a conversion ratio. Further, in the case where a bias voltage is applied to the greater color difference signal, a bias voltage is found in accordance with a ratio of the greater color difference signal and smaller color difference signal and applied to the other smaller color difference signal.

A plurality of leads are formed on a wiring board which is adhered onto a light transmitting member for transmitting a light beam. A plurality of electrode pads are formed, corresponding to the leads, on a photoelectric converting device. An anisotropically conductive film is formed between each of the leads and each of the corresponding electrode pads.

An auto focus apparatus for a camera comprising a group of lenses which include a focus lens and a zoom lens. The auto focus apparatus also comprises a focus detector, a motor and a controller. The focus detector detects whether the camera is in focus or not. The motor drives the focus lens and zoom lens. The controller controls the motor for driving the zoom lens and the focus lens. When the focus detector does not detect a focused image through the focus lens, the zoom lens is then driven to focus the camera. A method of auto focusing comprises the step of driving a focus lens so as to obtain a focusing point. The method of auto focusing also comprises the steps of detecting whether the camera is in focus or not, and driving the zoom lens when a focusing point is not achieved by the focus lens.

The driver circuit for a two-dimensional, CCD image sensor provides a pulse elimination period before the start of each field shift. During this elimination period, the operation of transmission registers is stopped so that the amplitude of a signal component used for even field shifting substantially matches the amplitude of another signal component used for odd field shifting, such that, as a result, the output signal of the image sensor is free of flickering.

An image pickup apparatus such as a video camera including a pickup tube, a diaphragm mechanism and an electrochromic filter plate which are disposed along the optical path of incident image light on the pickup tube. When an illuminance of an object to be photographed is lower than a predetermined illuminance, only the diaphragm mechanism is used to suitably control an exposure of the pickup tube. However, when the illuminance of the object exceeds the predetermined illuminance level, the diaphragm mechanism is operated to keep its aperture size at a predetermined aperture size which is larger than an original minimum aperture size corresponding to a pinhole state. At the same time, the electrochromic filter plate continuously changes its light transmissivity in response to an aperture control signal, thereby controlling the exposure of the pickup tube.

The invention provides a color image pickup device in which image light from a white object to be photographed or image light integrated by a diffusion plate or the like is incident on a pickup tube through an electrochromic element. Two primary color signals are separated from a video signal from the pickup tube, a voltage corresponding to a difference between the two primary color signals is detected by a differential amplifier, and the voltage is then applied across an electrochromic element. A spectral transmittance of which is then controlled, thereby achieving an optimal white balance.

A television camera equipped with an active filter section capable of producing dynamic special effects in the picture. The filter section of the camera includes an electro-optic light control device which is arranged in the optical path of the imaging optical section of the television camera such that its light transmittance for the incident light to the image screen of the camera is varied in response to the application of an electric signal, and the variable transmittance area is divided into a plurality of sections adapted to be controlled and drived selectively. Also, the camera includes a drive unit for selectively controlling and driving the sections of the electro-optic light control device so as to vary with time the spread of the area of the sections having the transmittance varied in response to the application of the electric signal.

A color image pick-up apparatus using a single planar array of solid state light-sensitive elements with a color mosaic filter. The color mosaic filter is made up of three types of elements occurring in repeating patterns which are such that luminance-type elements occur at every other element portion along both of two orthogonal direction. The signal corresponding to luminance is separated from the output signal of the solid state light-sensitive elements and delayed for one horizontal scanning period. The high frequency component of the delayed signal is extracted. The extracted high frequency component signal is added to the signal corresponding to luminance which is succeedingly produced from the solid state light-sensitive elements.
