Abstract

An image processing system including a display apparatus, a plurality of image capture units and an image processing apparatus is provided. The plurality of image capture units each include a camera capturing an image data, a storage unit storing segment information for identifying each of segments divided from the image data, and importance degrees calculated for the segments, an image compressing unit compressing each of the segments of the image data, and a transmitting unit transmitting the compressed image data to the image processing apparatus. The image processing apparatus includes a network interface unit inputting the compressed image data, an image generating unit generating a combined image data based on the compressed image data, and a transmitting unit transmitting the combined image data to the display apparatus, and the display apparatus includes a receiving unit receiving the combined image data and a display unit displaying the combined image data.

Claims

1. An image processing system, comprising:

a display apparatus displaying image data;

a plurality of image capture units mounted on a vehicle and capturing images of surroundings of a vehicle; and

an image processing apparatus connected with the plurality of image capture units via a network in the vehicle to generate a combined image data based on a plurality of image data captured by the image capture units, and connected with the display apparatus, and

wherein the plurality of image capture units each include;

a camera capturing an image data of one of surrounding parts of the vehicle;

a storage unit storing segment information for identifying each of segments divided from the image data captured by the camera, and importance degrees calculated for the segments based on resolutions which are required of the segments in the image data upon generation of the combined image data;

an image compressing unit compressing each of the segments of the image data at a compression ratio depending on a corresponding importance degree for each of the segments, and generating compressed image data; and

a transmitting unit transmitting the compressed image data to the image processing apparatus through the network,

the image processing apparatus including;

a network interface unit inputting the compressed image data transmitted from each of the image capture units;

an image generating unit generating a combined image data based on the compressed image data; and

a transmitting unit transmitting the combined image data to the display apparatus, and

the display apparatus including;

a receiving unit receiving the combined image data transmitted from the image processing apparatus; and

a display unit displaying the combined image data.

2. The system according to claim 1, wherein the importance degrees stored in the storage unit in each of the image capture units are information calculated based on pixel scaling factors of pixels in the image data for conversion into the combined image data.

3. The system according to claim 2, wherein the pixel scaling factors are information corrected depending on a distance between the vehicle and a position corresponding to each pixel in the combined image data.

4. The system according to claim 1, wherein the transmitting unit of each image capture unit divides the image data into plurality of packet data so that a size of each packet data changes depending on an amount of the compressed image data, and transmits the packet data to the image processing apparatus.

5. The system according to claim 2, wherein the transmitting unit of each image capture unit divides the image data into plurality of packet data so that a size of the each packet data changes depending on an amount of the compressed image data, and transmits the packet data to the image processing apparatus.

6. The system according to claim 3, wherein the transmitting unit of each image capture unit divides the image data into plurality of packet data so that a size of the each packet data changes depending on the amount of the compressed image data, and transmits the packet data to the image processing apparatus.

7. An image capture unit capturing an image data of surroundings of a vehicle, connected with an image processing apparatus via network in the vehicle to generate a combined image data based on a plurality of image data, the image capture unit comprising:
