Abstract
An input image processing apparatus includes a FIFO memory (FIFO-S) in which region selection information for specifying a selected region in an input image frame, in order to consecutively store in an image memory pixel data within a selected region in an arbitrary shape defined on the image frame. The FIFO memory provides a signal for indicating write of pixel data included in the selected region into the image memory, based on the region selection information.
Claims20
An input image processing apparatus for storing in an image memory only pixel data included in a selected region defined in an image frame inputted from an image input device, comprising:
- a region selection memory for storing region selection information for specifying the selected region in the image frame;
- and
- write indication means for indicating write of the pixel data included in the selected region into the image memory based on the region selection information.
An input image processing apparatus for storing in an image memory only pixel data included in a selected region defined in an image frame which is composed of subframes inputted from a plurality of image input devices, comprising:
- region selection memory for storing region selection information for specifying the selected region in the image frame;
- a plurality of subframe memories for storing the pixel data inputted from the image input devices respectively;
- read specifying means for specifying the subframe memory from which the pixel data is to be read;
- and
- write indication means for indicating write of the pixel data included in the selected region into the image memory based on the region selection information.
An input image processing method for storing pixel data alone included in a selected region defined in an image frame inputted from an image input device, including the steps of:
- determining whether or not the inputted pixel data is included in the selected region;
- and
- writing the pixel data included in the selected region into the image memory.
An input image processing method for storing pixel data alone included in a selected region defined in an image frame inputted from a plurality of image input devices, including the steps of:
- storing the pixel data inputted from each of the image input devices in a corresponding subframe;
- reading the pixel data from the subframe memories;
- and
- writing the pixel data included in the selected region among the pixel data read from the subframe memories into the image memory.
