When a selector button is pressed in optical viewfinder mode, a display in live view mode is started. If the metered light value, measured focus detection result, and position information stored in the optical viewfinder mode are set so as to be reflected in the live view mode, exposure control is performed based on the stored metered light value and position information, and focusing is performed based on the stored focus detection result and position information.

A light emitting device wherein one of a plurality of juxtaposed discharge tubes which is to remain not emitting light is prevented from being caused to emit light by induction by an adjacent one of the discharge tubes which is to emit light, thereby enabling fully independent control of light emission by the discharge tubes. In the light emitting device, trigger electrodes of each adjacent ones of a plurality of juxtaposed discharge tubes are located at opposite positions to each other with respect to the adjacent discharge tubes.

A chip saw in which chips are brazed onto the peripheral edge thereof is clamped, and is rotated while bringing a rotational brush into contact with a honing-subjected portion of the peripheral edge. A liquid, which has dustproof oil and abrasive powder, provided with abrasive properties is supplied to a part in which the rotational brush is in contact with the honing-subjected portion. Therefore, the work efficiency of honing process is improved, and sawdust is not generated. This makes it possible to easily take countermeasures against environmental problems and effectively use resources. In addition, the liquid can be easily recycled.

A photographing apparatus with a simple mechanism in which an AF sensor is employed as a light adjusting sensor. The apparatus includes a multi-AF sensor having a plurality of detecting areas for receiving light passing through a photographing lens, an AF controller for determining a focus area based upon signals outputted from the multi-AF sensor, and a light emitter for projecting light towards an object to be photographed. Prior to a main flash emission, the light emitter emits light preliminarily. On the basis of signals which are outputted from the detecting areas of the multi-AF sensor and which correspond to a reflected light from the object at time of emitting the preliminary flash light, a suitable area which outputs a suitable signal for photography is selected. On the basis of the signal of the suitable area thus selected, the amount of light of the main flash emission is determined.

In a camera system for exposing an image of an object in each frame on a film, an inherent film number is optically exposed in a predetermined region on the film which is disposed before a first frame and not exposed. Furthermore, all frame data such as shutter speed, aperture number, and so on with respect to all frames on the same film are recorded together in a file in a memory card. A name corresponding to the inherent film number is used as a name of the file.

An automatic-focusing camera is provided with a multiple-point distance-measurement device having a plurality of distance-measurement areas, a multiple-division photometry device having a plurality of photometry areas, and a multiple-division light-amount-control device having a plurality of light-amount-control areas. Part of the photometry areas and part of the light-amount-control areas correspond to the distance-measurement areas. When a taking lens is focused on a subject, its focus is locked. Out of the information obtained from the multiple-point distance-measurement device, a set of information obtained when the focus of the taking lens is locked is compared with a set of information obtained immediately before a shot is taken, and thereby a change in picture composition after the locking of the taking lens focus is detected. This makes it possible to achieve exposure control in ambient-light shooting and light amount control in flash shooting in accordance with a change in picture composition. Based on the information obtained from the multiple-point distance-measurement device, the subject and the background are identified, and, in accordance with the distribution of the subject and the background, the reference value to be used to stop emission of illumination light and the contribution ratios of the individual light-amount-control areas relative to the total amount of light received are determined to achieve light amount control in flash shooting.
