摘要： In order to reduce the capacity of a line memory when converting image data that are input in a raster scan order into pixel block data such as 8×8 pixels for JPEG compression and the like, data on the first 0th to 7th lines is written in an 8H line memory in a raster scan order. Next, while performing block reading, the writing of the next 8th to 15th lines is performed so as to follow the part that has been read. The block reading of the 8th to 15th lines is performed in an order from the area where the data on the 0th line was first stored to the area where the data on the 1st, 2nd . . . lines was stored. For this reason, the writing of the 16th to 23rd line that is performed simultaneously with the block reading of the 8th to 15th lines can be performed in the same manner as the writing of the first 0th to 7th lines. Therefore, block conversion can be performed using an 8H line memory capacity corresponding to 8 lines, whereas that corresponding to 16 lines has been conventionally required.
摘要翻译：为了在将以光栅扫描顺序输入的图像数据转换为像JPEG压缩等8×8像素的像素块数据时，为了降低行存储器的容量，将第0〜第7行的数据写入8H 行存储器以光栅扫描顺序。接下来，在进行块读取的同时，执行下一个第8至第15行的写入，以便跟随已经读取的部分。第8〜15行的块读取以从第0行的数据首次存储的区域到第1，第2的数据的区域的顺序进行。。。行被存储。为此，可以以与第一至第七行的写入相同的方式执行与第八至第十五行的块读取同时执行的第16至第23行的写入。因此，可以使用对应于8行的8H行存储器容量来执行块转换，而通常需要对应于16行的块转换。

摘要： From horizontal and vertical coordinate values HC and VC of a pixel, a distance operation unit calculates a distance value RV indicating the distance from an optical-axis position to the pixel. A correction-data operation unit receives the distance value RV, and calculates correction data CD for the pixel by referring to an approximation function indicating relation between distance values and correction data. The approximation function is divided into a plurality of segments, and in each segment represented by a quadratic function defined by a predetermined number of sample points.

摘要： A preprocessor converts an analog image signal, which is outputted from a solid-state image pickup sensor that photoelectric-converts an optical image of a subject, into digital image data. A timing generator periodically generates a drive pulse for driving the solid-state image pickup sensor continuously/discontinuously, and generates an output stop position signal that indicates an output stop position of the solid-state image pickup sensor when the solid-state image pickup sensor is driven discontinuously in sync with the drive pulse. A continuous data generator lets through the image data when the output stop position signal is invalid, and converts the image data inputted in a discontinuous state into continuous image data when the output stop position signal is valid.
