Abstract

The present invention is an image transmission terminal including: an image capture unit (17, 47) that outputs pixel signals; an image data generating unit (18, 48) that generates and outputs image frame data; a first image data compression unit (19, 49) that compresses and outputs the image frame data; a second image data compression unit (21, 51) that either leaves the image frame data uncompressed or else compresses and outputs the image frame data; an image selection unit (11, 13, 41, 43) that receives an operation input from a user, and selects the image frame data; an image data storage unit (22, 38, 52, 69) that stores the image frame data output from the second image data compression unit; and an image transmission unit (20, 50, 38) that wirelessly transmits the image frame data.

An image transmission terminal comprising:

an operating unit;
an image capture unit that outputs a pixel signal that corresponds to an amount of light irradiated onto an imaging element;
an image data generating unit that generates and then outputs an image frame data based on the pixel signal;
a first image data compression unit that compresses the image frame data at a predetermined compression rate and then outputs the image frame data;
a second image data compression unit that, when receiving a command to keep the image frame data uncompressed or to compress the image frame data at a lower compression rate than the predetermined compression rate from the operating unit, outputs a non-compression image frame data which remains uncompressed or a low-compression image frame data in which the image frame data is compressed at a lower compression rate than the predetermined compression rate;
an image data storage unit that stores the non-compression image frame data or the low-compression image frame data output from the second image data compression unit;
and
an image transmission unit that wirelessly transmits the image frame data stored in the image data storage unit and output from the second image data compression unit, wherein
the image transmission unit configured to operate at least one of a first image transmission process that wirelessly transmits the image frame data output from the second image data compression unit and stored in the image data storage unit during a transmission blank period in wireless transmission of the image frame data continuously output from the first image data compression unit, or a second image transmission process that wirelessly transmits the image frame data output from the second image data compression unit and stored in the image data storage unit after receiving a stop command of wireless transmission of the image frame data continuously output from the first image data compression unit via the operating unit.
