An image calibration method applied to an image calibration device includes comparing a first image with a second image to acquire a first overlapping region of the first image and a second overlapping region of the second image, analyzing color distribution of the first overlapping region to acquire at least one first base color value, analyzing color distribution of the second overlapping region to acquire at least one second base color value, setting a ratio of the at least one first base color value to the at least one second base color value as an luminance compensation value when the at least one first base color value is greater than the at least one second base color value, and utilizing the luminance compensation value to adjust pixels of the second image. The first overlapping region is overlapped with the second overlapping region.

Image calibration method and image calibration device

An image-capturing device includes a camera module and a controller. The camera module captures an image of an object. The camera module includes a first camera and a second camera. The first camera has a first field of view (FOV) and captures an image in the first FOV, so as to produce a first image. The second camera is adjacent to the first camera and has a second FOV, in which the first FOV is wider than the second FOV. The second camera captures an image in the second FOV, so as to produce a second image. A displayer displays one of the first and second images. When a zoom ratio of the first image increases, the controller selects a display region in the first image according to an object distance, such that the display region is enlarged and then displayed on the displayer.

Image-capturing device and method for operating image-capturing system of two cameras

An image capturing device with automatic white balance and an automatic white balance correction method are provided. The image capturing device includes a lens assembly, a light diffuser, an image sensor and a processor. The relative position of the light diffuser and the lens assembly is fixed. The processor is electrically connected to the image sensor having a first sensing region and a second sensing region. The light diffuser converts a fraction of the incident light to the reference light. The first sensing region converts the incident light to the display image information. The second sensing region converts the reference light to the correction information. The processor determines a reference gain average according to at least one color gain of the correction information and obtains at least one color gain correction value according to the reference gain average to adjust the white balance setting of the display image information.
