Monitoring system for a photography unit, monitoring method, computer program, and storage medium

Abstract

A coverage area picture imaging a maximum area is displayed on a coverage area picture display. A camera is moved within a predetermined range and a plurality of frames obtained as a result form a picture. The pixels of the picture is decimated in vertical and horizontal directions and form a thumbnail as the coverage area picture. The coverage area picture display presents a display indicating a direction in which the camera is currently directed for picture photographing. In accordance with the display, a photographing direction is controlled. A plurality of frames are photographed with respect to a designated position, then stored, and displayed. A whole picture display presents a whole panorama picture. A selective picture display presents a frame at the position designated within the whole panorama picture as a selected picture.

         33 . A signal processing apparatus comprising:
 a store configured to store a whole image from which plural images to be transmitted are extracted;   an input configured to receive a currently photographed whole image from which plural images to be transmitted are extracted;   a first encoding section configured to encode a first image comprised of the stored or received whole image by a first encoding process with a first resolution, the encoded first image being decodable by a first decoding process;   a second encoding section configured to encode a second image comprised of at least one of the plural frames of the first image by a second encoding process with a second resolution higher than the first resolution, the encoded second image being decodable by a second decoding process;   a setting section configured to set an area in the first image in which the at least one of the plural frames is located and select, for encoding as the encoded second image, the at least one of the plural frames in the set area; and   an output section configured to output the first and second encoded images for decoding;   wherein the first encoding process is different from the second encoding process.   
     
     
         34 . A signal processing apparatus according to the  claim 33 , wherein the first encoding process includes image compression to compress image data more than the second encoding process. 
     
     
         35 . A signal processing apparatus according to the  claim 33 , wherein the output section is controlled such that when the first and second images are displayed, the second image is displayed larger than the first image. 
     
     
         36 . A signal processing apparatus according to the  claim 33 , wherein the setting section is configured to change at least one of brightness, resolution and contrast of the second image.

 receive a currently photographed whole image from which plural images to be transmitted are extracted; 
 encode a first image comprised of the stored or received whole image by a first encoding process with a first resolution, the encoded first image being decodable by a first decoding process; 
 encode a second image comprised of at least one of the plural frames of the first image by a second encoding process with a second resolution higher than the first resolution, the encoded second image being decodable by a second decoding process; 
 set an area in the first image in which the at least one of the plural frames is located and select, for encoding as the encoded second image, the at least one of the plural frames in the set area; and 
 output the first and second encoded images for decoding; 
   wherein the first encoding process is different from the second encoding process.   
     
     
         41 . A signal processing apparatus according to the  claim 40 , wherein the first encoding process includes image compression to compress image data more than the second encoding process. 
     
     
         42 . A signal processing apparatus according to the  claim 40 , when the first and second images are displayed, the second image is displayed larger than the first image. 
     
     
         43 . A signal processing apparatus according to the  claim 40 , wherein the circuitry is configured to change at least one of brightness, resolution and contrast of the second image.
