摘要:
On the light-entering surface side of a base material 10, a coating layer 11 in which a high-refractive layer and a low-refractive layer are sequentially disposed alternately on one on the other is provided for blocking infrared radiation. One of the high-refractive layers is configured by an ITO film 11a so that the conductivity is increased on the surface of the coating layer. Herein, in view of preventing, to a further extent, the attachment of dirt and dust by providing the conductivity to the surface of the coating layer, it is desirable if the outermost high-refractive layer is made of a transparent conductive material. Moreover, it is desirable if the total layer thickness is 140 nm or smaller for the refractive layers formed outside of the high-refractive layer made of the transparent conductive material.

There is provided an imaging apparatus having a viewfinder optical system; a first image sensor; a photometric sensor; and optical path changing means. The viewfinder optical system has a first reflective surface that reflects a monitoring luminous flux, and the first reflective surface changes a reflection angle of the monitoring luminous flux. A change in a reflection angle of the first reflective surface causes a course of the monitoring luminous flux to be switched between a first optical path and a second optical path. In a case of second optical path, a travel direction is changed with the optical path changing means placed on the second optical path, causing a photometric processing to be performed using the first image sensor, while in a case of the first optical path, the photometric processing is performed using the photometric sensor.

In a camera having an automatic flash light control system, a quantity of flash light illuminating an object is restricted by a value as an upper limit or a lower limit which is calculated by a distance to the object and an aperture value of a taking lens. When there is any factor for affecting the calculation of the value such as a high reflectance of the object, a specific lens system of the taking lens and a position of the flashing unit with respect to the camera, the limit value is compensated or the restriction by the value is release. When the flash light control has completed, the flash light control mode is distinguished by indication manner corresponding to the result of the actual flash light control.

An imaging apparatus includes a first imaging sensor, a second imaging sensor, a display unit, an electronic viewfinder unit, a position changing unit and a sensor-shift shaking correction unit. The first imaging sensor acquires an image relating to a subject at the time of main photography. The second imaging sensor acquires an image relating to the subject before the time of main photography. The sensor-shift shaking correction unit performs shaking correction at the time of the main photography, by changing a position of the first sensor with the position changing unit. The electronic viewfinder unit performs consecutive image display on a display screen of the display unit, based on images sequentially acquired by the second imaging sensor before the main photography, and includes an electronic shaking correction unit that performs shaking correction of the consecutive image display, by changing the display position of the images on the display screen.

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.
