[0024] The first embodiment of the present invention will be applied to a digital still camera with reference to several descriptions in the drawings.

[0025] figure 1 Shows the appearance of a digital still camera, mainly showing the settings of the front surface and the upper surface.

[0026] The digital still camera 1 includes a photographing lens 2, a self-timer light 3, an optical viewfinder window 4, a microphone 5, a flash emission unit 6 and a grip bar 7 on the front surface of an almost rectangular thin-plate-shaped metal external body. The power button 8 and the shutter button 9 (designated unit) are provided at the right end of the upper surface (viewed from the user's position).

[0027] The taking lens 2 has an AF function and a zoom function that changes the focal length in a stepless manner. The taking lens 2 is retracted into the main body when the power is turned off or used for reproduction of the basic mode.

[0028] The grip bar 7 is a buried belt-shaped pr...

[0078] The second embodiment of the present invention will be applied to a digital still camera with reference to several descriptions in the drawings.

[0079] The appearance is basically the same as figure 1 The appearance shown is the same, and the electronic circuit configuration is basically the same as figure 2 The configuration shown is the same. The same reference numerals denote the same components, and the explanation and description thereof will be omitted.

[0080] The operation of the second embodiment will be explained.

[0081] Basically, the controller 22 executes the following steps according to a permanently stored program.

[0082] In the second embodiment, the shutter key 9 operates by two stroke operations. As a basic operation, an AF operation is performed to lock the in-focus state and the exposure state through a first stroke generally referred to as a “half stroke”. The shooting in the locked in-focus state and the exposure state is performed by a second...

[0111] The third embodiment of the present invention will be applied to a digital still camera with reference to several descriptions in the drawings.

[0112] The appearance is basically the same as figure 1 The appearance shown is the same, and the electronic circuit configuration is basically the same as figure 2 The configuration shown is the same. The same reference numerals denote the same components, and the explanation and description thereof will be omitted.

[0113] The operation of the third embodiment will be explained.

[0114] Basically, the controller 22 executes the following processing according to a permanently stored program.

[0115] In the third embodiment, the shutter key 9 operates by two stroke operations. As a basic operation, an AF operation is performed to lock the in-focus state and the exposure state through a first stroke generally referred to as a “half stroke”. The shooting in the locked in-focus state and the exposure state is performed by a seco...

Abstract

Perform fixed-focus shooting by quickly canceling autofocus without any labor for mode switching, etc. An image sensing device, comprising: a photographing unit (11, 12, 13), which has an automatic focus function and photographs an object image; a key input unit (30), which includes a shutter key (9) with two operating strokes, and is operated The first stroke designates automatic focus and automatic exposure, and shoots by operating the second stroke; and the focus control unit (227), which automatically sets the correct exposure value in the shooting unit (11, 12, 13), detects the shutter key (9 ) the predetermined operating states of the designated first and second strokes, and switch and select whether to operate the autofocus function or to set a fixed focus position for obtaining a predetermined depth of field according to the detection result.

Description

Invention field [0001] The present invention relates to an image sensing device and an image sensing method suitable for digital still cameras, portable phones with camera functions, and the like, and also relates to a recording medium for recording the shooting method. technical background [0002] Traditionally, a camera with an auto focus (AF) function takes pictures with a fixed focus with a predetermined depth of field without using the AF function in order to take a snapshot image or quickly without any mistake in the case where it is difficult to focus the lens by the AF function Take a picture (see, for example, Patent Reference 1). [0003] [Patent Reference 1] [0004] Japanese Patent Application Publication No. 2002-090823. [0005] In Patent Reference 1, it is necessary to arbitrarily select the auto focus mode and the fixed focus mode using a mode switch. In the fixed focus mode, it is impossible to quickly shoot immediately after switching from the state of selectin...
