IMAGE TRANSMISSION METHOD AND IMAGE TRANSMISSION APPARATUS
First Claim
1. An image transmission method comprising:
- setting an interest region, which is a transmission target, in an imaging region defined by a first unit of at least one pixel data item that is less than a fixed number of pixel data items obtained by a plurality of imaging elements of an image sensor for a data block;
extending the interest region so as to obtain an extension interest region defined by the fixed number of pixel data items of the data block as a second unit, and obtaining an extension range from the interest region to the extension interest region;
imaging with the image sensor, obtaining pixel data using respective imaging elements which capture an image of the imaging region, and collecting pixel data items included in the extension interest region into the data block;
outputting the data block included in the extension interest region from the image sensor; and
erasing pixel data of the extension range from the output data block so as to obtain the image of the interest region.

Abstract
An image transmission method, from an image sensor which collects a fixed number of pixel data items obtained by a plurality of imaging elements into a data block, and outputs the pixel data items, including a transmission region setting step of setting an interest region by using a unit lower than the fixed number, a region extension step of extending the interest region to obtain an extension interest region in which the data block is represented as a unit and obtaining extension ranges from the interest region to the extension interest region, an imaging step of performing imaging with the image sensor, an output step of outputting the data block included in the extension interest region from the image sensor, and an extension range erasing step of erasing pixel data of the extension ranges from the output data block so as to obtain an image of the interest region.
