解 像(かいぞう)

かいぞう

noun

resolution (of an image)

1. resolution; image resolution

The degree of detail visible in an image, whether on a screen, in a photograph, or through an optical instrument. Almost always appears in the compound 解像度(かいぞうど) (resolution as a measurable quantity).

解像度(かいぞうど)が高(たか)い画像(がぞう)を選(えら)んだ。

I chose a high-resolution image.

このカメラの解像度(かいぞうど)はどのくらいですか。

What is the resolution of this camera?

Increasing the screen resolution displays text and photos more clearly, but the battery drains faster as a result.

Composed of 解(かい) (resolve, analyze) and 像(ぞう) (image). In practice, 解像(かいぞう) almost never appears alone — it is nearly always used in the compound 解像度(かいぞうど) (resolution, literally "degree of image resolution"). This is an essential technology term for discussing cameras, displays, printers, and digital media.

Note: the homophone 改造(かいぞう) (remodeling, modification) is a completely different word.
