摘要:
A method includes capturing an optical image to form raw data indicative of the optical image and using a look-up table to transform the raw data into transformed data that indicates a second image. A white color balance of the second image is computed, and the values in the look-up table are modified based on the computed white color balance.

An optical serial link may be formed of an optical transceiver and a reflective wavelength coupler. The coupler may reflect light beams of different wavelengths using an elliptical reflector and a dispersive element.
摘要:
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.
