Abstract

According to one embodiment, a camera includes a lens, a liquid crystal display panel, an imaging device on which light is made incident through the lens and the liquid crystal display panel, a first driver configured to drive the imaging device to capture an image of an object, a camera substrate on which the imaging device and the first driver are arranged, and a second driver configured to drive the liquid crystal display panel to display a specific image. The liquid crystal display panel is between the lens and the imaging device.

Claims (24)

1 . A camera comprising:

a lens;

a liquid crystal display panel;

an imaging device on which light is made incident through the lens and the liquid crystal display panel;

a first driver configured to drive the imaging device to capture an image of an object;

a camera substrate on which the imaging device and the first driver are arranged; and

a second driver configured to drive the liquid crystal display panel to display a specific image, wherein

the liquid crystal display panel is between the lens and the imaging device,

the camera substrate is a ball grid array substrate comprising a plurality of solder balls arranged in an array state, and

the liquid crystal display panel is connected to the camera substrate via the plurality of solder balls.

2 . The camera of claim 1 , wherein

the liquid crystal display panel is arranged at a position of an aperture diaphragm of the lens.

3 . The camera of claim 1 , wherein

the first driver synchronizes displaying the specific image by the second driver with capturing an image of the object.

4 . The camera of claim 1 , wherein

the second driver is arranged on the camera substrate.

5 . The camera of claim 1 , wherein

the liquid crystal display panel comprises a first substrate, a second substrate, and a liquid crystal layer arranged between the first substrate and the second substrate,

the first substrate is a flexible printed wiring board comprising a plurality of active elements and a plurality of pixel electrodes, and

the first substrate is connected to the camera substrate.

6 . The camera of claim 1 , further comprising:

a processor to which an image captured by the imaging device is input, wherein

the second driver displays at least two specific images on the liquid crystal display panel, and

the processor calculates a distance to the object, in accordance with a shape of blur of at least two images of the object with which the at least two specific images overlap, respectively.
