摘要： An electronic imaging camera is provided with a substantially expanded dyanmic exposure range by implementing two succeeding exposure intervals under conditions where the exposure defining parameters are substantially different and thereafter selectively choosing between the electronic information signals sensed during the two succeeding exposure intervals to provide an output signal from which a visible image of the subject may be reconstructed thereafter. The camera comprises an image sensing array (14) comprising a predetermined number of discrete image sensing areas all of which are responsible to incident illumination from a subject to provide an electronic information signal corresponding to the intensity of the illumination incident thereto; an image storing array (16) for storing the electronic information signal; and control means. The control means controls first and second, different, select sets of exposure defining parameters to implement first and second exposure intervals during which the image sensing array (14) is exposed to incident illumination, and transfers the electronic information signal derived during each exposure interval from the image sensing array (14) to the storing array (16). Means (28,30,36) selectively combines the electronic information signal derived during the first and second exposure intervals to provide an output electronic information signal comprising a first selected component of the electronic information signal derived during the first exposure interval and second selected component of the electronic information signal derived during the second exposure from which a visible image of the subject may be constructed.

摘要： image sensing and processing apparatus in which the different colours of a subject (12) are sensed by a linear image sensor (20) to provide a high resolution electrical colour separation signal and a low resolution electrical colour separation signal which is stored in a memory (42). An enhanced high resolution electrical colour separation signal is thereafter provided as a function of the colour matrixing of the low resolution electrical colour separation signals with the high resolution electrical colour separation signals.
