A headset is able to be coupled via a cable to an intercom system, is able to be wirelessly coupled to a wireless device via a wireless transceiver of the headset, and is able to be connected to a wired device via another cable. A controller of the headset separately monitors the microphone conductors and audio conductors by which the headset may be coupled to the intercom system to detect whether or not one or both of a communications microphone and an acoustic driver of the headset are coupled to the intercom system, and monitors the operating state of the wireless transceiver to detect whether or not the wireless transceiver is inactive, on standby or in use; and selectively couples a system ground conductor to one of the microphone conductors, and selectively provides a local microphone bias voltage in response to what is observed through such monitoring.

Intercom headset connection and disconnection detection

An electronic imaging module is disclosed which is removably insertable into a photographic camera for reversibly converting the camera into an electronic imaging camera. The electronic imaging module includes a sensing unit, a processing unit, and a coupling unit. The sensing unit detects an object image and converts the image to a corresponding electrical signal. The processing unit, which is configured for location within the camera's film cassette holder, includes a storage unit for storing the electrical signal and a transmission link for transmitting the electrical signal to external devices such as a control unit or a base unit. The coupling unit couples the sensing unit to the processor unit. The coupling unit is adjustable to ensure that the sensing unit is in alignment with the camera optical path and the film plane and the processing unit is secured within the film cassette holder.

Electronic imaging module for reversibly converting a photographic

A defect correction apparatus for a solid state imaging device employs a frame buffer responsively coupled to the imaging device for storing digital values of shuttered dark pixel data from image locations of the imaging device. A register responsively coupled to the imaging device and having an output coupled to the buffer sequentially clocks digital values of image pixel data of the imaging device into the frame buffer. A comparator having an output operatively coupled to the register and being responsively coupled to the dark pixel data of the frame buffer produces enable and inhibit outputs. When any selected element of dark pixel data is less than a threshold, indicative of an operative pixel element in the imaging device, data stored in the register corresponding to the pixel is stored in the frame buffer in response to the enable signal. When the value of the dark pixel data in the frame buffer is greater than the threshold the comparator produces an inhibit signal. The value of image data of a previous operative pixel element is thereby entered into the register and frame buffer.

An apparatus and method for high speed parallel processing of image data corresponding to picture elements of an image in which the image data for each picture element is formatted as a binary word for multiplication by a plurality of different coefficients also in binary format. Parallel processing is accomplished by a plurality of multiplication circuits each of which stores select coefficients and receives binary formatted image data words simultaneously in timed sequence from the least significant data bit to the most significant data bit.

Electronic image processing circuit

Apparatus for encoding electronic still image information signals to a form suitable for recording on a conventional recording media by dividing the electronic information signals into a plurality of groups of electronic information signals wherein each group corresponds to a plurality of different picture elements of the still image. Decoding apparatus is also provided for recording the electronic information signals from the different groups into their original order so as to enable reconstruction of the still image. The encoding apparatus may also be adapted to transmit conventional electronic video image information signals interspersed with the selectively encoded electronic still image information signals for recording on the conventional storage media. The decoding apparatus operates to separate the electronic still image information signals from the electronic video image information signals prior to decoding.

A system and method for formatting a composite still and moving image defining electronic information signal by interspersing a high resolution still image defining electronic information signal in alternate fields with a moving image defining electronic information signal such that a plurality of succeeding alternate still image defining fields collectively define a single high resolution still image. The system and method also operates to deformat the composite still and moving image defining electronic information signal by first separating the moving and still image defining electronic information signals from each other and thereafter interpolating a second field from each first field of each frame of moving image defining electronic information signals to enable the display of a continuous moving image without interruption. The plurality of succeeding alternate frames of high resolution still image defining electronic information signals are also combined to enable the display of a high resolution still image.

Apparatus and method for electronically recording in rapid succession high resolution still images in digital format utilizing a nonvolatile electronically programmable read only memory (EPROM) module for storing the still images. Digitally formatted image data may be rapidly transferred for storage in the EPROM module by simultaneously transferring binary bit data from a plurality of latches to corresponding ones of a plurality of EPROM circuits which collectively form one of a plurality of groups of EPROM circuits which comprise the EPROM module.
