Abstract:
1. An imaging apparatus comprising: image pickup means including a plurality of photoelectric converters arranged in a matrix from which image data is obtained by XY address control; and a peripheral circuit connected to the photoelectric converters by a wiring layer formed on a surface of the image pickup means opposite a light-receiving surface of the image pickup means and held integrally with the image pickup means to process image data provided by the image pickup means and to provide the processed image data, wherein the peripheral circuit includes at least image compressing means compressing the image data and providing the compressed image data, the image compressing means including: a specific area image compressing unit compressing sub-image data obtained by a sub-set of the plurality of photoelectric converters and providing a first code amount; a code amount assignment control unit estimating a second code amount for the image data based on the first code amount and determining a data compressing ratio based on the estimated second code amount; and a total area image compressing unit compressing the image data based on the data compressing ratio, wherein the specific area image compressing unit and the total area image compressing unit are different units, wherein the image data is obtained in a sequence corresponding to the processing of the image data by the image compressing means, and wherein the sequence is one of a line sequence, a column sequence, or a block sequence.
