Abstract
Pixel processors each having a depth register, an intensity register and an adder are connected in a linear array. Each pixel processor processes one pixel on a horizontal scan line. A token having plane segment information is shifted in one direction in the array, and each pixel processor updates the registers while it performs hidden surface elimination in a time-division fashion. A refresh token for an intensity data output is also shifted in one direction, and intensity data stored in each pixel processor is supplied to an intensity data bus. A hardware of the pixel processor is very much simplified and LSI implementation is facilitated while maintaining a high image output rate.
