Color measuring systems and methods are disclosed. Perimeter receiver fiber optics are spaced apart from a central source fiber optic and receive light reflected from the surface of the object being measured. Light from the perimeter fiber optics pass to a variety of filters. The system utilizes the perimeter receiver fiber optics to determine information regarding the height and angle of the probe with respect to the object being measured. Under processor control, the color measurement may be made at a predetermined height and angle. Various color spectral photometer arrangements are disclosed. Translucency, fluorescence and/or surface texture data also may be obtained. Audio feedback may be provided to guide operator use of the system. The probe may have a removable or shielded tip for contamination prevention.

Controlling functions of a handheld multifunction device

An electronic still camera is provided with an electronic image sensor for generating an image signal corresponding to a still image of a subject and an orientation determination section for sensing the orientation of the camera relative to the subject. The orientation determination section provides an orientation signal recognizing either the vertical or the horizontal orientation of the camera relative to the subject. An image processor is responsive to the orientation signal for processing the image signal and correcting the orientation thereof so that the still image is output from the image processor in a predetermined orientation. In this way, the electronic still camera can be positioned in a variety of orientations relative to a subject, including both clockwise and counterclockwise vertical "portrait" orientations and a horizontal "landscape" orientation, without affecting the orientation of the images output by the camera.

To appropriately adjust luminance and a black level even when characteristics of an organic EL display element should be changed due to an environmental change or heat self-generation, to display a stable image. A current detector detects a level of a total panel current flowing in an organic EL panel. The detected level is subjected to A/D conversion before being supplied to an adder. Meanwhile, a video signal is supplied to a current calculator 24 to be converted into data corresponding to the level of a total panel current, before being supplied to the adder. The adder then compares an average total panel current level, estimated based on a video signal, and an actual total panel current level, to obtain a difference so that a black level for image data to be supplied to the panel is adjusted according to the difference.
