M64283FP
Image Sensor (Artificial Retina Chip)
1. Overview
M64283FP is a CMOS image sensor of 128 ×
128 pixels, which supports an image-
processing function and an analog signal
calibration, a device that allows information
compression and parallel processing like
human retina. M64283FP can achieve high
performance, a compact system and low
power consumption for an image-processing
apparatus.

Figure 3. Filter Configuration with P, M and X registers
Figure 4 shows an example of filter setting. To output a positive image from an origin of an image area, set 1
to the least significant bit P0 of the P register as shown in Figure 4 (a). To output an edge image, set 1 to the
least significant bit M0 of the M register as shown Figure 4 (b). Figure 5 (a), (b) and (c) show the examples of
setting P, M, and X registers to output an edge image.
