Actual sensor size

Note: Actual size is set to screen → change »
This is the actual size of the DiMAGE E500 sensor: ~5.75 x 4.32 mm
The sensor has a surface area of 24.8 mm². There are approx. 5,200,000 photosites (pixels) on this area. Pixel pitch, which is a measure of the distance between pixels, is 2.19 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 4.8 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. Konica-Minolta DiMAGE E500 has a pixel density of 20.9 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.

Diagonal

The diagonal of DiMAGE E500 sensor is not 1/2.5 or 0.4" (10.2 mm) as you might expect, but approximately two thirds of that value - 0.28" (7.19 mm). If you want to know why, see sensor sizes.

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


Konica-Minolta DiMAGE E500 diagonal:

w = 5.75 mm
h = 4.32 mm
Diagonal =  5.75² + 4.32²   = 7.19 mm


Surface area

Surface area is calculated by multiplying the width and the height of a sensor.

Width = 5.75 mm
Height = 4.32 mm

Surface area = 5.75 × 4.32 = 24.84 mm²


Pixel pitch

Pixel pitch is the distance from the center of one pixel to the center of the next measured in micrometers (µm). It can be calculated with the following formula:
Pixel pitch =   sensor width in mm  × 1000
sensor resolution width in pixels

Konica-Minolta DiMAGE E500 pixel pitch:

Sensor width = 5.75 mm
Sensor resolution width = 2629 pixels
Pixel pitch =   5.75  × 1000  = 2.19 µm
2629


Pixel area

The area of one pixel can be calculated by simply squaring the pixel pitch:
Pixel area = pixel pitch²

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

Konica-Minolta DiMAGE E500 pixel area:

Pixel pitch = 2.19 µm

Pixel area = 2.19² = 4.8 µm²


Pixel density

Pixel density can be calculated with the following formula:
Pixel density =  ( sensor resolution width in pixels )² / 1000000
sensor width in cm

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

Konica-Minolta DiMAGE E500 pixel density:

Sensor resolution width = 2629 pixels
Sensor width = 0.575 cm

Pixel density = (2629 / 0.575)² / 1000000 = 20.9 MP/cm²


Sensor resolution

Sensor resolution is calculated from sensor size and effective megapixels. It's slightly higher than maximum (not interpolated) image resolution which is usually stated on camera specifications. Sensor resolution is used in pixel pitch, pixel area, and pixel density formula. For sake of simplicity, we're going to calculate it in 3 stages.

1. First we need to find the ratio between horizontal and vertical length by dividing the former with the latter (aspect ratio). It's usually 1.33 (4:3) or 1.5 (3:2), but not always.

2. With the ratio (r) known we can calculate the X from the formula below, where X is a vertical number of pixels:
(X × r) × X = effective megapixels × 1000000    →   
X =  effective megapixels × 1000000
r
3. To get sensor resolution we then multiply X with the corresponding ratio:

Resolution horizontal: X × r
Resolution vertical: X

Konica-Minolta DiMAGE E500 sensor resolution:

Sensor width = 5.75 mm
Sensor height = 4.32 mm
Effective megapixels = 5.20
r = 5.75/4.32 = 1.33
X =  5.20 × 1000000  = 1977
1.33
Resolution horizontal: X × r = 1977 × 1.33 = 2629
Resolution vertical: X = 1977

Sensor resolution = 2629 x 1977


Crop factor

Crop factor or focal length multiplier is calculated by dividing the diagonal of 35 mm film (43.27 mm) with the diagonal of the sensor.
Crop factor =   43.27 mm
sensor diagonal in mm


Konica-Minolta DiMAGE E500 crop factor:

Sensor diagonal = 7.19 mm
Crop factor =   43.27  = 6.02
7.19

35 mm equivalent aperture

Equivalent aperture (in 135 film terms) is calculated by multiplying lens aperture with crop factor (a.k.a. focal length multiplier).

Konica-Minolta DiMAGE E500 equivalent aperture:

Crop factor = 6.02
Aperture = f2.8 - f4.8

35-mm equivalent aperture = (f2.8 - f4.8) × 6.02 = f16.9 - f28.9
