Abstract
The disclosure provides an image capturing device and an image capturing method. The image capturing device includes a tone mapping circuit, a color correction circuit, and a color gamut mapping circuit. The tone mapping circuit obtains a first image including a first pixel and performs a tone mapping operation to obtain a brightness adjustment parameter, where the first pixel includes a plurality of first color channels. The color correction circuit converts the first color channels into a plurality of second color channels based on the brightness adjustment parameter and the brightness of the first pixel. The color gamut mapping circuit performs a color gamut mapping operation on the second color channels to convert the second color channels into a plurality of third color channels, and outputs a second image, where the second image includes the second pixel characterized by the third color channels.
