Electronic camera with imaging condition information display control
View Patent ↗An electronic camera includes a shutter button. When the shutter button is half-depressed, a photographing condition such as an exposure time period and an aperture amount is adjusted by a main CPU, and characters indicative of the adjusted photographing condition are displayed on an LCD. When the shutter button is full-depressed, an image signal of an object is recorded in a recording medium. It is noted that a time difference between a timing of half-depressing the shutter button and a timing of full-depressing the shutter button is lower than a threshold value, a flag is set to “1”, and a display of the characters is prohibited. Prohibiting the characters from being displayed makes it possible to promptly execute a photographing of the object in response to the full-depression of the shutter button.
1. An information display controlling method of an electronic camera, the electronic camera having a shutter button, a central processing unit, a focus lens and a display, comprising steps of:
(a) imaging an object and generating an object image signal;
(b) executing by the central processing unit of the electronic camera a through image pre-exposure processing of the object image signal;
(c) determining whether the shutter button of the electronic camera is half depressed prior to adjusting an imaging condition;
(d) determining whether the shutter button of the electronic camera has been fully depressed within a predetermined period of time prior to adjusting an imaging condition;
(e) adjusting the imaging condition of the object image signal;
(f) displaying an object image from the object image signal and imaging condition information obtained as a result of the adjustment of the imaging condition on the display of the electronic camera if it is determined in step (c) that the shutter button is half depressed;
(g) displaying the object image from the object image signal and not displaying the imaging condition information on the display at least until a main exposure is performed if it is determined in step (d) that the shutter button has been fully depressed within the predetermined period of time; and
(h) performing a main exposure of the object.
2. An information display controlling method of an electronic camera, the electronic camera having a shutter button, a central processing unit, a focus lens and a display, comprising steps of:

(d) determining whether the shutter button of the electronic camera has been fully depressed within a predetermined period of time prior to conducting an automatic focus and automatic exposure of the object image signal;
(e) conducting an automatic focus and automatic exposure of the object image signal and setting an optimal exposure time period and optimal aperture amount and setting the focus lens of the electronic camera to a determined focal point;
(f) displaying an object image from the object image signal and the optimal exposure time period and the optimal aperture amount on the display of the electronic camera if it is determined in step (c) that the shutter button is half depressed;
(g) displaying the object image from the object image signal and not displaying the optimal exposure time period and the optimal aperture amount on the display at least until a main exposure is performed if it is determined in step (d) that the shutter button has been fully depressed within the predetermined period of time; and
(h) performing a main exposure of the object.
