Even a person other than a user can obtain useful information when searching for a photographed image having a desired content or configuration. A feature extraction unit 106 includes a plurality of feature extraction units A, B,... For extracting different features from an image. The image data captured by the imaging unit 109 in response to the imaging instruction and temporarily stored in the image data memory 111 is transferred to the feature extraction unit 106 and the compression / encoding unit 112. Then, the feature extraction unit 106 extracts a feature by any one of the feature extraction units A, B,... Selected in advance according to the transmission destination of the image, and the extracted feature is the feature data encoding unit. It is encoded at 107. The image data itself is compressed and encoded by the compression / encoding means 113, and the compressed and encoded image data and the encoded feature data are multiplexed and recorded in the image data memory 115. Is done. [Selection] Figure 2 |
