Abstract

There is provided an image encoding apparatus including an encoding part performing encoding processing on each image processing unit including a plurality of encoding units and generating encoded data, and a sorting / marker-inserting part sorting the encoding units in the encoded data in encoding processing order for one screen and inserting a marker as a delimiter for encoding processing using a correlation with an immediately preceding encoding unit.

Description

technical field [0001] The present technology relates to an image encoding device, an image encoding method, and a program. Specifically, when generating encoded data in which a marker is inserted as a delimiter for compression processing, it is possible to reduce the buffer capacity and make it possible to reduce the size of the encoded data in which the marker is inserted. An easier image encoding device, image encoding method and program are produced. Background technique [0002] In the past, an imaging apparatus such as a digital camera performs image processing on an image signal as a result of imaging, and performs encoding processing after accumulating data for one screen in a buffer. This is due to the fact that a general image encoding method represented by JPEG (Joint Photographic Experts Group) generally encodes images of one frame in raster order. However, in order to hold image data for one screen, a buffer with a large storage capacity is highly required. In...
