Abstract:
1. An image processing apparatus comprising: a receiving unit that receives a point sequence image; a point-plane conversion unit that performs a point-plane conversion processing for the image received by the receiving unit; a plurality of lossy encoding units that perform a lossy encoding processing for the point-plane conversion image by using the point-plane conversion unit, each of the lossy encoding units corresponds to one of a plurality of color components; and a control unit that performs control such that transmission of the image to the lossy encoding unit from the point-plane conversion unit is controlled to synchronize lossy encoding processings of the plurality of lossy encoding units by maintaining a difference between quantization steps of the respective lossy encoding units to be within a predetermined value, and each lossy encoding unit changes processing variables used in the encoding processing based on a code amount of the processing result of the lossy encoding unit.
