An electronic apparatus and a method of generating a depth map are provided. The electronic apparatus includes a projection device, a first camera, a second camera, and a processing device. The projection device projects patterned invisible light on a scene. The first camera captures visible light information to generate a first image. The second camera captures visible light information and invisible light information to generate a second image. The processing device receives the first image and the second image. A first depth information unit in the processing device compares visible light images of the first image and the second image to obtain first depth information, and a second depth information unit in the processing device identifies an invisible light image in the second image to obtain second depth information. The processing device generates a depth map of the scene from the first depth information and the second depth information selectively.

Electronic apparatus and method of generating depth map

An image capturing apparatus and a photo composition method thereof are proposed. The method is adapted to an image capturing apparatus having a first lens and a depth sensor and includes the following steps. First, a preview frame of a scene is obtained by using the first lens, and depth information of the scene is obtained by using the depth sensor. Next, scene analysis is performed on the preview frame according to the depth information so as to generate a scene analysis result. Next, whether the preview frame satisfies a photo composition requirement is determined according to the scene analysis result and a corresponding photo composition rule. If yes, the first lens is controlled to capture the preview frame; if no, a photo composition suggestion corresponding to the scene is provided according to the photo composition rule corresponding to the scene analysis result.

Image capturing apparatus and photo composition method thereof

The disclosure provides a method and a system for multi-lens module alignment, adapted to perform alignment on a multi-lens module having at least a first lens and a second lens during its manufacturing stage, where the method includes the following steps. A calibration object is first captured by using the first lens and the second lens to accordingly generate intrinsic parameters and external parameters of the first lens and the second lens, where the external parameters of the first lens and the second lens are associated with a common reference coordinate system. A target object is next captured by using the first lens and the second lens, and captured images of the target object are processed by using the intrinsic parameters and the external parameters to generate rectified images. The first lens and the second lens are adjusted and aligned according to the rectified images.
