MOVING IMAGE CAPTURING DEVICE, INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING DEVICE, AND IMAGE DATA PROCESSING METHOD

摘要

A capture device is equipped with a stereo camera, and generates a plurality of demosaiced images of different sizes in which the left and right frame images have been reduced in stepwise fashion. Further, by cycling through the pixel rows of the rows of the images according to a predetermined rule to produce a connected stream, there is generated a virtual composite image that includes the plurality of demosaiced images, in which the pixel rows of the rows are pixel rows having undergone one round of connection. A host terminal sends to the capture device a data request signal designating a plurality of areas within the composite image, having a shared range in the longitudinal direction. The capture device clips out the designated areas, and sends to the host terminal a stream of a new composite image comprising only the clipped out areas. The host terminal cuts this into separate images, which are expanded into consecutive addresses in a main memory.

主权项

1. A moving image capturing device comprising:
an image data generation unit configured to generate a plurality of pieces of image data from each frame image of a moving image obtained by capturing an image of a target object, and configured to sequentially output the image data as a stream for each single horizontal row of pixels; an image synthesis unit configured to cyclically connect the plurality of pieces of image data, which is output from the image data generation unit, for each single horizontal row of pixels or for each row of pixels for a range smaller than the single horizontal row, and configured to output resultant data as a stream so as to generate a virtual synthesized image which includes the plurality of images and in which a row of pixels that results when a connection cycle is completed is defined as a horizontal row of pixels; and an image transmission unit configured to receive, from a connected host terminal, a request to transmit data specifying a plurality of rectangular areas having a common vertical range in the virtual synthesized image, configured to crop out ranges corresponding to the rectangular areas for each row of pixels of the virtual synthesized image output by the image synthesis unit, configured to connect the ranges, and configured to transmit as a stream to the host terminal.
