A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes a graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. The graphics pipeline renders and prepares images for display at least in part in response to polygon vertex attribute data and texel color data stored as a texture images in an associated memory. An efficient texturing pipeline arrangement achieves a relatively low chip-footprint by utilizing a single texture coordinate / data processing unit that interleaves the processing of logical direct and indirect texture coordinate data and a texture lookup data feedback path for “recirculating” indirect texture lookup data retrieved from a single texture retrieval unit back to the texture coordinate / data processing unit. Versatile indirect texture referencing is achieved by using the same texture coordinate / data processing unit to transform the recirculated texture lookup data into offsets that may be added to the texture coordinates of a direct texture lookup. A generalized indirect texture API function is provided that supports defining at least four indirect texture referencing operations and allows for selectively associating one of at least eight different texture images with each indirect texture defined. Retrieved indirect texture lookup data is processed as multi-bit binary data triplets of three, four, five, or eight bits. The data triplets are multiplied by a 3×2 texture coordinate offset matrix before being optionally combined with regular non-indirect coordinate data or coordinate data from a previous cycle / stage of processing. Values of the offset matrix elements are variable and may be dynamically defined for each cycle / stage using selected constants. Two additional variable matrix configurations are also defined containing element values obtained from current direct texture coordinates. Circuitry for optionally biasing and scaling retrieved texture data is also provided.

A solid-state image sensor has a plurality of pixels, a read-out circuit and a signal processing section. The plurality of pixels includes a plurality of first pixels, a plurality of second pixels, a plurality of third pixels and a plurality of fourth pixels. The signal processing section includes a color acquisition section, a first judgment section configured to determine whether or not the white data value W in the target pixel block is smaller than a predetermined first set value, and a white color correction section configured to perform correction processing of the white color data value W in the target pixel block based on the following Expression (1) when the judgment result of the first judgment section is NO, and to output the white data value W by itself without performing the correction processing based on the Expression (1) when the judgment result of the first determination section is YES;W′=S1C1+S2C2+S3C3  (1)where each of S1, S2, and S3 is a coefficient that is determined based on a color balance.
