Japanese Patent JP2612711
Kind Code:
B2
Abstract:
PURPOSE:To always recognize a photographing magnification and an area where photographing is possible when photographing is performed by displaying in a finder a viewing angle which a variable power optical system is available at a maximum photographing magnification, etc., and the current photographing magnification. CONSTITUTION:If the variable power of the optical system is set at eight times, the image of an object 1 is formed on a CCD 3 being a photographing element through the optical system 2, is converted into electrical signals, is signal- processed by a signal processing part 4, and is recorded by a recorder part 5. On the other hand, an optical image incident on a zoom magnification detecting sensor 7 from the object 1 is detected by an encoder composed of a rotating angle detector for a sensor 43. A value corresponding one vs one to said detected value is read out of a ROM tape in a lens control circuit 8, and a display signal generator 9 generates characters at a zoom magnification corresponding to the optical image and superimpose signals. The characters are superimposed and displayed in the electric view finder EVF 11 together with the detected value in the sensor 7. Thus the current magnification used can be recognized.
