DETAILED DESCRIPTION

In order to allow the advantages, spirit and features of the present invention to be more easily and clearly understood, the embodiments and appended drawings thereof are discussed in the following. However, the present invention is not limited to the embodiments and appended drawings.

Please refer to FIG. 1. FIG. 1 shows the block diagram of the image process apparatus 10. The image process apparatus 10 includes an image capture device 20, a filter 30, a mixture unit 40, an input interface, an output interface, and a receiver 70. The image capture device 20 captures an original image and generates a depth map corresponding to the original image. In one embodiment of this invention the image capture device 20 includes a stereo camera with two or more image sensors therein to captures a first image and a second image corresponding to the original image. The image capture device 20 could generate the depth map based on the first image and the second image generated from the stereo camera. To generate the depth map, synchronized signal could be embodied in each scan line of each frame of the first and the second image by the image capture device 20. For example, the first image includes a first frame and the second image includes a second frame, and the image capture device inserts synchronized signal in each scan line of the first and the second frames.

In one example, the first and the second frames each includes 720 scan lines, the first scan line of the first frame corresponds to the first scan line of the second frame. The same synchronized signal is embodied to the first scan line of the first frame and the first scan line of the second frame, such that the depth map information regarding the first scan line of the first frame and the first scan line of the second frame can be calculated. The frequency of the synchronized signal is changeable dependent on the number of the scan line (or resolution) of the first and the second images.

Of course, in another embodiment this original image could include a stream video data with a set of original frame, and the depth map includes a plurality of depth map information corresponding to the set of original frame. For example, the first image includes a first set frame and the second image includes a second set of frame, and the depth map includes a plurality of depth map information which is generated by the image capture device based on the first set frame and the second set of frame. The plurality of depth map information corresponds to the set of original frame.

The original image comprises at least a first object within the first depth range of the depth map and a second object not within a first depth range of the depth map. In one example the first object could include a man 31 and a woman 32 in front of a display 100 within the first depth range between Z1 and Z2, and the second object could be an floor light 33 outside the first depth range, as shown in FIG. 2.

The receiver 70 stores the value of the first depth range which could be predetermined. On the other hand, the receiver 70 includes a setting device to change the value of the first depth range stored in the receiver. For example, this setting device could be a button on the image process apparatus 10 for users to adjust the first depth range. In another example, this setting device could be a wireless interface to receive the value of the first depth range from a remote controller.

The filter 30 based on the depth map and the first depth range in the receiver 70 removes the second object (such as the floor light 33 in FIG. 2) from the original image and generates a temporary image which just includes the first object (such as the man 31 and the woman 32 in FIG. 2). In such situation, those objects outside the first depth range of the depth map will be removed from the original image by the filter 30, and the temporary image just includes the rest objects within the first depth range of the depth map. In another example, the filter just picks up or selects the first object from the original image and generates a temporary image which includes the first object.

In another example, the filter further includes a recognition device to identify the first object in the first depth range which is moving, and generates a temporary image which only includes the moving first object within the first depth range.

The input interface 50 is provided to receive the input image. This input interface 50 could be a USB interface, a HDMI interface, a thunderbolt interface, or other interface which could receive the input image. The mixture unit 40 combines the temporary image with the input image and generates a blending image. For example, the input image is the mountain image as shown in FIG. 3. Of course, in another embodiment, the input image can be a stream video or a movie with a set of frames.

Based on the temporary image and the input image in FIG. 3, the blending image generated by the mixture unit 40 is shown in the FIG. 4 as follows. That is, the blending image includes the input image and the first object. In another example, the mixture unit 40 further includes a transforming device to deform the first object and the blending image includes the deformed object. For example, the man 31 is deformed and looks taller as shown in the FIG. 5.

The output interface 60 is provided to output the blending image. This output interface 60 could be a USB interface or other interface which could output the output image. For example, the output interface 60 includes a HDMI interface which can output the blending image to an external display 100.

FIG. 6 shows an example outlook of the image process apparatus which includes a box 80. The input interface 50 and the output interface 60 are respectively disposed within the box to receive the input image and output the blending image. The receiver 70 is also disposed within the box 80 to receive the value of the first depth range determined by the user. The image capture device 20 is disposed on the box 80 and the view angle of the image capture device 20 is adjustable, either manually or automatically, to capture the first object. For example, the image capture device 20 is rotated manually to capture the first object within the first depth range.

With the examples and explanations mentioned above, the features and spirits of the invention are hopefully well described. Importantly, the present invention is not limited to the embodiments described herein. Those skilled in the art will readily observe that numerous modifications and alterations of the device may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
