Abstract: An electronic device includes a camera that includes an automatic exposure module. The automatic exposure module is configured to determine an exposure for a picture by automatically adjusting an aperture size, shutter timing, and/or an ISO setting. The automatic exposure module is further configured to automatically adjust at least one parameter in addition to the aperture size, shutter timing and/or ISO setting in determining the exposure for the picture.

Abstract: A fluorescence imaging system. A light source irradiates an object to be viewed. The irradiated object is imaged through a beam-splitting system to form individual displaced images of the object. The displaced images are further filtered in a filter having a frequency passband different from the other filters. The filtered images are imaged on a detector. The same image point of each image is detected and converted into an electrical signal. A circuit means is provided to receive the signals of each common image point, and weight the same. The weighted signal represents an image point pixel. The weighted pixels are displayed as an image of the object having improved contrast.
