Problems solved by technology

2D sensors lack the ability to measure the third dimension (for example, along the Z axis in a Cartesian coordinate system)
Also, making 2D pixels much larger to fit 3D pixels is not advisable, as this will compromise the resolution of the 2D information
In such cases, improved resolution means increased size and increased cost

Embodiment Construction

[0023] The drawings depict preferred embodiments of the invention for purposes of illustration only. It should be noted that same or similar reference numbers in the figures may indicate same or similar functionality. Those skilled in the art will readily recognize from the following discussion that alternative embodiments of the structures and methods disclosed herein may be utilized without departing from the inventive principles herein. It should be appreciated that the following examples focus on webcams, but embodiments of the invention are applicable to other image capture devices as well.

[0024] FIG. 1 is a block diagram illustrating a possible usage scenario with an image capture device 100 , a host system 110 and a user 120 .

[0025] In one embodiment, the data captured by the image capture device 100 is still image data. In another embodiment, the data captured by image capture device 100 is video data (accompanied in some cases by audio data). In yet another e...

Abstract

The present invention is a system and method for the use of a 3D sensor in an image capture device. In one embodiment, a single 3D sensor is used, and the depth information is interspersed within the information for the other two dimensions so as to not compromise the resolution of the two-dimensional image. In another embodiment, a 3D sensor is used along with a 2D sensor. In one embodiment, a mirror is used to split incoming light into two portions, one of which is directed at the 3D sensor, and the other at the 2D sensor. The 2D sensor is used to measure information in two dimensions, while the 3D sensor is used to measure the depth of various portions of the image. The information from the 2D sensor and the 3D sensor is then combined, either in the image capture device or in a host system.

Description

technical field [0001] The present invention relates generally to digital cameras for capturing still images and video, and more particularly to the use of 3D sensors in such cameras. Background technique [0002] Consumers are increasingly using digital cameras to capture both still image and video data. Webcams (digital cameras that connect to host systems) are also becoming more common. Additionally, other devices that include digital image capture capabilities, such as camera-equipped cell phones and personal digital assistants (PDAs), are storming the market. [0003] Most digital image capture devices include a single sensor in two dimensions (2D). As the name implies, such 2D sensors measure values ​​in only two dimensions (for example, along the X and Y axes in a Cartesian coordinate system). 2D sensors lack the ability to measure a third dimension (for example, along the Z axis in a Cartesian coordinate system). Therefore, not only is the created image two-dimen...
