Abstract
Official abstract text for this publication.
A camera device is provided. The camera device includes a flash unit, an image capture module, and a controller. The flash unit generates a preset flash with a predetermined Correlated Color Temperature value to illuminate an object, and the image capture module captures a test image from the object when the preset flash illuminates the object. The controller determines an adjusted CCT value according to a color difference between the test image and a predetermined color. When the controller has determined the adjusted CCT value, the flash unit generates an adjusted flash with the adjusted CCT value to illuminate the object. When the adjusted flash illuminates the object, the image capture module captures an adjusted image.
First claim
Opening claim text (preview).
What is claimed is: 1. A camera device, comprising: a flash unit, generating a preset flash with a predetermined Correlated Color Temperature value (CCT value) to illuminate an object, wherein the flash unit comprises an electrochromic layer and an LED module having a first LED and a second LED, and the first LED and the second LED have different CCT values from each other; an image capture module, capturing a test image from the object when the preset flash illuminates the obj…
