Sensor size comparison
Sensor size is generally a good indicator of the quality of the camera. Sensors can vary greatly in size. As a general rule, the bigger the sensor, the better the image quality.

Bigger sensors are more effective because they have more surface area to capture light. An important factor when comparing digital cameras is also camera generation. Generally, newer sensors will outperform the older.

Pixel pitch tells you the distance from the center of one pixel (photosite) to the center of the next. It tells you how close the pixels are to each other.

The bigger the pixel pitch, the further apart they are and the bigger each pixel is. Bigger pixels tend to have better signal to noise ratio and greater dynamic range.

Pixel pitch of IXUS 510 HS is approx. 34% higher than pixel pitch of WX200.
Pixel area

Pixel or photosite area affects how much light per pixel can be gathered. The larger it is the more light can be collected by a single pixel.

Larger pixels have the potential to collect more photons, resulting in greater dynamic range, while smaller pixels provide higher resolutions (more detail) for a given sensor size.

Diagonal

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

Sony WX200 diagonal

The diagonal of WX200 sensor is not 1/2.3 or 0.43" (11 mm) as you might expect, but approximately two thirds of that value - 7.7 mm. If you want to know why, see sensor sizes.

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

Canon IXUS 510 HS diagonal

The diagonal of IXUS 510 HS sensor is not 1/2.3 or 0.43" (11 mm) as you might expect, but approximately two thirds of that value - 7.7 mm. If you want to know why, see sensor sizes.

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


Surface area

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

WX200 sensor area

Width = 6.16 mm
Height = 4.62 mm

Surface area = 6.16 × 4.62 = 28.46 mm²

IXUS 510 HS sensor area

Width = 6.16 mm
Height = 4.62 mm

Surface area = 6.16 × 4.62 = 28.46 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

WX200 pixel pitch

Sensor width = 6.16 mm
Sensor resolution width = 4920 pixels
Pixel pitch =   6.16  × 1000  = 1.25 µm
4920

IXUS 510 HS pixel pitch

Sensor width = 6.16 mm
Sensor resolution width = 3665 pixels
Pixel pitch =   6.16  × 1000  = 1.68 µm
3665


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

WX200 pixel area

Pixel pitch = 1.25 µm

Pixel area = 1.25² = 1.56 µm²

IXUS 510 HS pixel area

Pixel pitch = 1.68 µm

Pixel area = 1.68² = 2.82 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

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

WX200 pixel density

Sensor resolution width = 4920 pixels
Sensor width = 0.616 cm

Pixel density = (4920 / 0.616)² / 1000000 = 63.79 MP/cm²

IXUS 510 HS pixel density

Sensor resolution width = 3665 pixels
Sensor width = 0.616 cm

Pixel density = (3665 / 0.616)² / 1000000 = 35.4 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

WX200 sensor resolution

Sensor width = 6.16 mm
Sensor height = 4.62 mm
Effective megapixels = 18.20
r = 6.16/4.62 = 1.33
X =  18.20 × 1000000  = 3699
1.33
Resolution horizontal: X × r = 3699 × 1.33 = 4920
Resolution vertical: X = 3699

Sensor resolution = 4920 x 3699

IXUS 510 HS sensor resolution

Sensor width = 6.16 mm
Sensor height = 4.62 mm
Effective megapixels = 10.10
r = 6.16/4.62 = 1.33
X =  10.10 × 1000000  = 2756
1.33
Resolution horizontal: X × r = 2756 × 1.33 = 3665
Resolution vertical: X = 2756

Sensor resolution = 3665 x 2756


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


WX200 crop factor

Sensor diagonal in mm = 7.70 mm
Crop factor =   43.27  = 5.62
7.70

IXUS 510 HS crop factor

Sensor diagonal in mm = 7.70 mm
Crop factor =   43.27  = 5.62
7.70

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).

WX200 equivalent aperture

Crop factor = 5.62
Aperture = f3.3 - f5.9

35-mm equivalent aperture = (f3.3 - f5.9) × 5.62 = f18.5 - f33.2

IXUS 510 HS equivalent aperture

Crop factor = 5.62
Aperture = f3.4 - f5.6

35-mm equivalent aperture = (f3.4 - f5.6) × 5.62 = f19.1 - f31.5
