A novel method and apparatus is disclosed for electronically sensing a negative and a positive in a novel integral film structure of the instant development type using light of different wavelengths so as to produce reflected light from the negative and the positive which are indicative of the luminance characteristics and the chrominance characteristics of the image. The novel integral film structure has a filter which allows the negative to be scanned. Specifically, the filter transmits incident infrared radiation to which silver halide emulsion layers are sensitive and blocks the transmission of radiation in the range of wavelengths to which the silver halide emulsion layers are sensitive.

A novel method and apparatus is disclosed for electronically sensing a negative and a positive in a novel integral film structure of the instant development type using light of different wavelengths so as to produce reflected light from the negative and the positive which are indicative of the luminance characteristics and the chrominance characteristics of the image. The novel integral film structure has a filter which allows the negative to be scanned. Specifically, the filter transmits incident radiation in the range of wavelengths other than a select range of wavelengths to which silver halide emulsion layers are sensitive and blocks the transmission of radiation in the range of wavelengths to which the silver halide emulsion layers are sensitive.

Method and apparatus for scanning of image in integral film structure

A compact, handheld portable electronic imaging system including both an electronic imaging camera and hard copy printer are separately housed with respect to each other and readily interconnectable with respect to each other for use either in combination or apart. Means for storing electronic images may be connected to the camera and/or printer housings so that when used apart image defining electronic image information signals may be initially directed for storage by the electronic imaging camera and the storage device thereafter connected to the printer for the making of hard copies therefrom. Alternatively, the electronic imaging camera and printer may be used in combination to provide an immediate hard copy of the image sensed in a manner analogous to that of an instant photographic camera of the self-processing type.
