Summary: | To provide an imaging apparatus, which achieves a use of an effective buffer memory in a continuous photographing.SOLUTION: A control part in an imaging apparatus 400 generating coding data in each of a plurality of sub bands by exchanging image data obtained by imaging to a frequency, and storing it into a storage medium, secures a first buffer memory temporally storing the coding data of a plurality of prescribed number of first image groups at first and a second buffer memory for temporally storing the coding data of a second image group imaged in sequence of each first image group in a continuous photographing mode in a memory, assigns a region of a size according to a ratio set in advance to each sub band in the first buffer memory, temporally stores the coding data of each sub band obtained by each first image group in each region, assigns the region of the size according to the ratio of a coding amount of each sub band of each first image group to each sub band in the second buffer memory, and temporally stores the coding data of each sub band obtained by the second image group in each region.SELECTED DRAWING: Figure 4
【課題】連写時において効率的なバッファメモリの利用を図る撮像装置を提供する。【解決手段】撮像して得た画像データを、周波数変換して複数のサブバンド毎の符号化データを生成し、記録媒体に記録する撮像装置400の制御部は、連写モードにおいて、最初から所定数の第1の画像群の符号化データを一時的に格納する第1のバッファメモリと、第1の画像群に後続して撮像される第2の画像群の符号化データを一時的に格納するための第2のバッファメモリとをメモリに確保し、第1のバッファメモリには、予め設定された比率に応じたサイズの領域をサブバンド毎に割り当て、領域それぞれに第1の画像群から得た各サブバンドの符号化データを一時的に格納し、第2のバッファメモリには、第1の画像群の各サブバンドの符号量の比率に応じたサイズの領域をサブバンド毎に割り当て、領域それぞれに第2の画像群から得た各サブバンドの符号化データを一時的に格納する。【選択図】図4 |
