Abstract
Provided are an apparatus for generating a compressed file, which includes a storage unit storing frame data including compressed image data; a header generator generating a header based on the frame data; and a file generator generating a compressed image file including the header and the compressed image data, a method for generating a compressed file, a camera module associated with the apparatus, and a terminal including the apparatus and the camera module.
Claims10
An apparatus for generating a compressed file, the apparatus comprising:
- a camera module configured to:
- generate raw image data by photographing an object,
- generate compressed image data from the raw image data,
- output a vertical synchronization signal, and
- output frame data including the compressed image data and thumbnail image data in response to the vertical synchronization signal;
- and
- a host system configured to:
- receive the frame data from the camera module in response to the vertical synchronization signal,
- parse the frame data based on a marker that indicates information for discriminating between the compressed image data and the thumbnail image data,
- separately store the compressed image data and the thumbnail image data,
- generate a header based on the frame data, and
- generate a compressed image file including the header and the compressed image data.
A method for generating a compressed file in a terminal having a camera module and a host system interfaced with the camera module, the method comprising:
- generating, via the camera module, raw image data by photographing an object;
- generating, via the camera module, compressed image data from the raw image data;
- and
- outputting, via the camera module, a vertical synchronization signal to the host system;
- outputting, via the camera module, frame data including the compressed image data and thumbnail image data to the host system in response to the vertical synchronization signal;
- receiving, via the host system, the frame data in response to the vertical synchronization signal;
- parsing the frame data based on a marker that indicates information for discriminating between the compressed image data and the thumbnail image data,
- separately storing the compressed image data and the thumbnail image data,
- generating, via the host system, a header based on the frame data;
- and
- generating, via the host system, a compressed image file including the header and the compressed image data.
