Problems solved by technology

However, in the case where through display is performed only when the focus evaluation value is increased, if a position difference of the lens such as shift or tilt occurs, there may be a case where through display will be performed , regardless of the direction of lens movement, so that when the focus evaluation value is just below or above its maximum value, the displayed image will jitter, causing an unpleasant feeling to the user

Embodiment Construction

[0036] The present invention will now be described with reference to the drawings showing preferred embodiments of the invention.

[0037] FIG. 1 is a block diagram showing an electrical configuration of a digital still camera as an image pickup device according to an embodiment of the present invention.

[0038] The digital camera 1 includes a CPU 11 that controls the operation of the entire camera, and a signal processing circuit 12 is connected to the CPU. Connected to the signal processing circuit 12 are an image pickup device 13 such as a CCD, a microphone 110 for inputting audio, and an image display device 14 such as an LCD (Transmissive Liquid Crystal Display). Also connected to the signal processing circuit 12 are: a signal output terminal 15 for outputting image signals and audio signals to an external device, a speaker 16 for outputting audio signals, and a memory 18 .

[0039] The image pickup device 13 converts the image focused by the lens portion 17 into an ele...

Abstract

An image pickup apparatus is provided which enables a user to follow up an object while viewing a display screen, and can prevent an image shake from being reflected on the display screen. An image pickup device outputs a signal in response to light received from an object via a lens section unit. A drive ring is rotated by the driving force of the AF motor to enable the lens section unit to move in a direction along the optical axis, to thereby carry out focus adjustment based on the signal output from the pickup device. A LCD displays an image based on the signal output from the image pickup device. The LCD displays the image according to through display when the lens section unit is being moved in a direction of extension, and the through display by the LCD is restrained after the lens section unit is reversed and is moved in a direction of retraction and until it is stopped.

Description

technical field [0001] The present invention relates to a camera such as a silver salt film, an electronic camera, a digital camera or a video camera, a control method thereof, and a control program for realizing the control method. Background technique [0002] Generally, in a retractable lens camera equipped with a retractable lens, zooming and focusing of the lens is usually performed while extending the lens by a lens extending mechanism. For the lens extension mechanism of this type of camera, an arrangement is widely used in which an annular drive ring with a cam is rotated, the member holding the lens is equipped with a translational movement mechanism which moves the lens along the optical axis lens while inhibiting the lens from rotating. However, with the miniaturization and increase in the number of pixels of image pickup devices such as CCDs, this configuration for moving the annular drive ring is now required so as to have greater flexibility in the positioning...
