[0026] FIG. 1 is a block diagram showing the configuration of a digital single-lens reflex camera 100 as an image pickup apparatus according to a first embodiment of the present invention.

[0027] The shutter 12 controls exposure of the imaging device 14 . The imaging device 14 converts an optical image into an electrical signal. In the single-lens reflex system, light incident on the lens 310 of the lens unit 300 passes through the aperture 312 , the lens mounts 306 and 106 , the mirror 130 and the shutter 12 to form an optical image on the camera device 14 .

[0028] The analog-to-digital converter 16 converts the analog signal output from the imaging device 14 into a digital signal. The timing generating circuit 18 supplies clock signals and control signals to the imaging device 14 , the analog-to-digital converter 16 and the digital-to-analog converter 26 . The timing generation circuit 18 is controlled by the memory control circuit 22 and the system control circuit 50 ...

Abstract

A digital single-lens reflex camera determines whether a predetermined time has passed since the start of display. If the predetermined time has not passed yet, the camera performs face detection to determine if a user is looking into an optical finder of the camera. When the face detection is performed, a system control circuit identifies the present content displayed. When the displayed content is an ordinary image, photographing information, or attention-seeking alert, display of the content is immediately stopped. When the displayed content is alert prohibiting imaging, it is checked whether a switch operation has been performed. If the switch operation has not been performed at all, or a switch operation for canceling the displayed alert has not been performed, timer counting is cleared before the timer counting is initiated again.

Description

technical field [0001] The present invention relates to an imaging device comprising a display device for displaying images and status information of the imaging device and a method for controlling the imaging device. Background technique [0002] Along with the downsizing of cameras, cameras that display information necessary for shooting, such as shutter speed and aperture value, as well as captured images on a display device thereof appear. Information such as shutter speed and aperture value, hereinafter referred to as "shooting information", needs to be set according to the environment, and it needs to be displayed before and after shooting. [0003] As for display devices for image display, liquid crystal display devices such as TFT (Thin Film Transistor) liquid crystal display devices, and organic EL (Electro Luminescence) devices and the like are known. Because of its size and configuration, each device is provided on the back of a camera similarly to a viewfinder, ...
