This is the actual size of the VR-320 sensor: ~6.16 x 4.62 mm
The sensor has a surface area of 28.5 mm². There are approx. 14,000,000 photosites (pixels) on this area. Pixel pitch, which is a measure of the distance between pixels, is 1.43 µm. Pixel pitch tells you the distance from the center of one pixel (photosite) to the center of the next.

Pixel or photosite area is 2.04 µm². The larger the photosite, the more light it can capture and the more information can be recorded.

Pixel density tells you how many million pixels fit or would fit in one square cm of the sensor. Olympus VR-320 has a pixel density of 49.07 MP/cm².

These numbers are important in terms of assessing the overall quality of a digital camera. Generally, the bigger (and newer) the sensor, pixel pitch and photosite area, and the smaller the pixel density, the better the camera. If you want to see how VR-320 compares to other cameras, click here.

Compare VR-320 with another camera




Diagonal is calculated by the use of Pythagorean theorem:
Diagonal =  w² + h²
where w = sensor width and h = sensor height

Olympus VR-320 diagonal:

w = 6.16 mm
h = 4.62 mm
Diagonal =  6.16² + 4.62²   = 7.70 mm

Surface area


Width = 6.16 mm
Height = 4.62 mm

Surface area = 6.16 × 4.62 = 28.46 mm²

Pixel pitch

Pixel pitch =   sensor width in mm  × 1000
sensor resolution width in pixels

Olympus VR-320 pixel pitch:

Sensor width = 6.16 mm
Sensor resolution width = 4315 pixels
Pixel pitch =   6.16  × 1000  = 1.43 µm

Pixel area

Pixel area = pixel pitch²

You could also divide sensor surface area with effective megapixels:
Pixel area =   sensor surface area in mm²
effective megapixels

Olympus VR-320 pixel area:

Pixel pitch = 1.43 µm

Pixel area = 1.43² = 2.04 µm²

Pixel density

Pixel density can be calculated with the following formula:
sensor width in cm

You could also use this formula:
Pixel density =   effective megapixels × 1000000  / 10000
sensor surface area in mm²

Olympus VR-320 pixel density:

Sensor resolution width = 4315 pixels
Sensor width = 0.616 cm

Pixel density = (4315 / 0.616)² / 1000000 = 49.07 MP/cm²

Sensor resolution



X =  effective megapixels × 1000000

Resolution horizontal: X × r
Resolution vertical: X

Olympus VR-320 sensor resolution:

Sensor width = 6.16 mm
Sensor height = 4.62 mm
Effective megapixels = 14.00
r = 6.16/4.62 = 1.33
X =  14.00 × 1000000  = 3244
Resolution horizontal: X × r = 3244 × 1.33 = 4315
Resolution vertical: X = 3244

Sensor resolution = 4315 x 3244

Crop factor

Crop factor =   43.27 mm
sensor diagonal in mm

Olympus VR-320 crop factor:

Sensor diagonal = 7.70 mm
Crop factor =   43.27  = 5.62

35 mm equivalent aperture


Olympus VR-320 equivalent aperture:

Crop factor = 5.62
Aperture = f3.0 - f5.9

35-mm equivalent aperture = (f3.0 - f5.9) × 5.62 = f16.9 - f33.2
