摘要： An imaging circuit generates a first video signal with a first exposure interval and a second video signal with a second exposure interval substantially at the same time, the second exposure interval being shorter than the first exposure interval, the first and second video signals respectively having first and second dynamic ranges which are different but continues. The first video signal is synchronized with the second video signal. An exposure ratio between the first and second exposure intervals is detected. A gain of the second video signal is adjusted according to the exposure ratio. A combined video signal is generated from the first and second video signals according to a mixing control signal indicative of a mixing ratio between first and second video signals and levels of the first and second video signals to have an expanded dynamic range such that the first dynamic range is connected to the second dynamic range with difference in gains of the first and second video signals adjusted for linearity. An edge enhancement signal may be gain-controlled or coring-controlled according to the mixing control signal or the exposure ratio. The similar apparatus and method for color signals are also disclosed. The output dynamic range for a display is limited by a non-linear process.

摘要： A device includes a photometry element for photometrically measuring object light while dividing the object light into a plurality of color components, and an exposure controller for calculating an exposure control value on the basis of a plurality of photometry outputs corresponding to the color components from the photometry element. In the device, the photometry element divides object light into a plurality of color components, e.g., R, G, and B three primary colors, and performs level detection in units of color components. The exposure controller preferably determines, as an exposure control value, a color component of a maximum level of the photometry outputs corresponding to the color components which are measured by the photometry element. Exposure control is executed by calculating an aperture value, a shutter speed, and the like on the basis of the determined exposure control value.

摘要： Modes of a camera are classified into groups according to their type. On an LCD panel, the different groups are displayed on different rows, and modes to be selected out of each group are displayed in different columns. Group selection is accomplished by vertically manipulating a selector button, and mode selection out of each group is accomplished by laterally manipulating the selector button. This makes possible displaying of selectable modes classified by group on the LCD panel in a way perceivable at a glance. Furthermore, the choice of a group and that of a mode within each group are matched in the mode display arrangement to facilitate the operation for mode selection.

摘要： In a camera a pickup element images an object image. An A/D converter A/D converts an output of the pickup element. A processing section includes a night scene judging section for judging whether or not the scene to be photographed is the night scene on the basis of a digital image signal output from the A/D converter. In a distance measuring apparatus of the camera. An area sensor is used for an auto-focus. A first judging section judges that the scene to be photographed is a night scene on the basis of an output of the area sensor. In the case where the first judging section judges that the photography scene is not the night scene, a second judging section judges whether or not the scene to be photographed is the reverse light scene. A main object specifying section specifies the main object in the case where either the first judging section or the second judging section judges the scene to be photographed is either the night scene or the reverse light scene. A distance measuring section conducts distance measuring calculation with respect to the main object specified by the main object specifying section.
