Abstract

The invention provides a camera device. The camera device includes a flash unit, an image capturing module and a controller. The flash unit generates a preset flash with a predetermined correlated color temperature value to illuminate the object, and the image capture module captures a test image from the object when the preset flash illuminates the object. The controller determines the correction correlated color temperature value according to the test image and the color difference between the predetermined colors. After the controller determines the corrected correlated color temperature value, the flashlight unit generates corrected flashlight with the corrected correlated color temperature value to illuminate the object. And when the calibration flash illuminates the object, the image capturing module captures a calibration image.

Description

technical field [0001] The present invention relates to a camera device, in particular to a camera device having a flash unit. Background technique [0002] Currently, although a flash can be used for taking pictures in a poor lighting environment, the correlated color temperature (CCT) of the flash may deviate from that of natural light (eg, sunlight). As a result, the colors of the resulting photos may appear unnatural. [0003] The flashes emitted by conventional flash units have a correlated color temperature set at the time of manufacture, and most flashes are designed to produce a fixed color temperature (about 5500K) corresponding to sunlight. However, flash at this color temperature may still produce unexpected effects on photos under certain circumstances. Therefore, there is a need for a flash unit that can produce a suitable color temperature. Contents of the invention [0004] The present invention provides a camera device, the above-mentioned camera device ...
