摘要： For each pixel read from an imaging device, a horizontal counter value and a vertical counter value corresponding to the pixel are supplied from a signal generator to a distance computation section via an optical-axis-center coordinate setting section and an up-and-down and right-and-left weighting section. In the distance computation section, the distance to the optical-axis center is computed, and correction coefficients for the zoom wide end and for the zoom tele end, which correspond to the distance, are obtained by look-up tables. The two obtained correction coefficients are blended at a mixture ratio determined by a blend ratio setting section. The blended shading correction coefficients are gain adjusted by a gain adjustment section, after which they are supplied to a correction section. As a result, a correction corresponding to the distance to the optical-axis-center position is performed on the signal of each pixel supplied from an imaging section.

摘要： The present invention relates to an image capturing apparatus and method in which the image recording time is reduced and the memory capacity required for compression is also reduced. A number-of-bytes calculation unit 302 determines the number of bytes after compression based on an integrated value of high-frequency integrated data supplied from a high-frequency integration processor. Based on the determined number of bytes, a Q-scale calculation unit 303 determines a Q-scale based on which the image data can be compressed one time to a predetermined data size. A Q-table generation unit 304 generates a Q-table based on the Q-scale. A DCT unit 321 performs a discrete cosine transform on the input image data. A quantization processor 322 adjusts the compression ratio of the image data based on the up-to-date Q-table supplied from the Q-table generation unit 304. A variable-length coding processor 323 encodes the image data with variable length coding such as Huffman coding, and outputs the resulting compressed image data. The present invention is applicable to digital cameras.

摘要： An image capturing apparatus for capturing an image with solid state imaging devices may include a compressing section, a memory, a decompressing section, and a signal processing section. The compressing section may compress digitalized data of an image captured with the solid state imaging devices. The memory may temporarily store the compressed image data that is compressed by the compressing section. The decompressing section may decompress the compressed image data that is read out from the memory. The signal processing section may perform an image quality correction operation on the image data decompressed by the decompressing section. The compressed image data may contain a maximum value and a minimum value of pixel data in a block, information regarding positions of the maximum value and the minimum value in the block, and quantized data.
