AR0130: 1/3-Inch CMOS Digital Image Sensor

Features

Readout Modes

Digital Binning

By default, the resolution of the output image is the full width and height of the FOV as

defined above. The output resolution can be reduced by digital binning. For RGB and

monochrome mode, this is set by the register R0x3032. For Context A, use bits [1:0], for

Context B, use bits [5:4]. Available settings are:

00 = No binning

01 = Horizontal binning

10 = Horizontal and vertical binning

Binning gives the advantage of reducing noise at the cost of reduced resolution. When

both horizontal and vertical binning are used, a 2x improvement in SNR is achieved

therefore improving low light performance

Bayer Space Resampling

All of the pixels in the FOV contribute to the output image in digital binning mode. This

can result in a more pleasing output image with reduced subsampling artifacts. It also

improves low-light performance. For RGB mode, resampling can be enabled by setting

of register 0x306E[4] = 1.

Mirror

Column Mirror Image

By setting R0x3040[14] = 1, the readout order of the columns is reversed, as shown in

Figure 15. The starting color, and therefore the Bayer pattern, is preserved when

mirroring the columns.

When using horizontal mirror mode, the user must retrigger column correction. Please

refer to the column correction section to see the procedure for column correction retrig-

gering. Bayer resampling must be enabled, by setting bit 4 of register 0 x 306E[4] = 1.
