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.

Kodak DC220		Canon PowerShot S100

Surface area:

39.69 mm²

42.47 mm²

Difference: 2.78 mm² (7%)

S100 sensor is approx. 1.07x bigger than DC220 sensor.

Note: You are comparing sensors of vastly different generations. There is a gap of 13 years between Kodak DC220 (1998) and Canon S100 (2011). Thirteen years is a huge amount of time, technology wise, resulting in newer sensor being much more efficient than the older one.

Pixel pitch

6.64 µm

1.87 µm

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.

Difference: 4.77 µm (255%)

Pixel pitch of DC220 is approx. 255% higher than pixel pitch of S100.

Pixel area

44.09 µm²

3.5 µm²

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.

Relative pixel sizes:

Pixel area difference: 40.59 µm² (1160%)

A pixel on Kodak DC220 sensor is approx. 1160% bigger than a pixel on Canon S100.

Pixel density

2.27 MP/cm²

28.6 MP/cm²

Pixel density tells you how many million pixels fit or would fit in one square cm of the sensor.

Higher pixel density means smaller pixels and lower pixel density means larger pixels.

Difference: 26.33 µm (1160%)

Canon S100 has approx. 1160% higher pixel density than Kodak DC220.

Diagonal

Diagonal is calculated by the use of Pythagorean theorem:

Diagonal = √

w² + h²

where w = sensor width and h = sensor height

Kodak DC220 diagonal

The diagonal of DC220 sensor is not 1/1.76 or 0.57" (14.4 mm) as you might expect, but approximately two thirds of that value - 9.09 mm. If you want to know why, see sensor sizes.

w = 7.27 mm
h = 5.46 mm

Diagonal = √

7.27² + 5.46²

= 9.09 mm

Canon S100 diagonal

The diagonal of S100 sensor is not 1/1.7 or 0.59" (14.9 mm) as you might expect, but approximately two thirds of that value - 9.41 mm. If you want to know why, see sensor sizes.

w = 7.53 mm
h = 5.64 mm

Diagonal = √

7.53² + 5.64²

= 9.41 mm

Surface area

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

DC220 sensor area

Width = 7.27 mm
Height = 5.46 mm

Surface area = 7.27 × 5.46 = 39.69 mm²

S100 sensor area

Width = 7.53 mm
Height = 5.64 mm

Surface area = 7.53 × 5.64 = 42.47 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

DC220 pixel pitch

Sensor width = 7.27 mm
Sensor resolution width = 1095 pixels

Pixel pitch =	7.27	× 1000	= 6.64 µm
	1095

S100 pixel pitch

Sensor width = 7.53 mm
Sensor resolution width = 4027 pixels

Pixel pitch =	7.53	× 1000	= 1.87 µm
	4027

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

DC220 pixel area

Pixel pitch = 6.64 µm

Pixel area = 6.64² = 44.09 µm²

S100 pixel area

Pixel pitch = 1.87 µm

Pixel area = 1.87² = 3.5 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

DC220 pixel density

Sensor resolution width = 1095 pixels
Sensor width = 0.727 cm

Pixel density = (1095 / 0.727)² / 1000000 = 2.27 MP/cm²

S100 pixel density

Sensor resolution width = 4027 pixels
Sensor width = 0.753 cm

Pixel density = (4027 / 0.753)² / 1000000 = 28.6 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

DC220 sensor resolution

Sensor width = 7.27 mm
Sensor height = 5.46 mm
Effective megapixels = 0.90

r = 7.27/5.46 = 1.33

X = √	0.90 × 1000000	= 823
	1.33

Resolution horizontal: X × r = 823 × 1.33 = 1095
Resolution vertical: X = 823

Sensor resolution = 1095 x 823

S100 sensor resolution

Sensor width = 7.53 mm
Sensor height = 5.64 mm
Effective megapixels = 12.10

r = 7.53/5.64 = 1.34

X = √	12.10 × 1000000	= 3005
	1.34

Resolution horizontal: X × r = 3005 × 1.34 = 4027
Resolution vertical: X = 3005

Sensor resolution = 4027 x 3005

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

DC220 crop factor

Sensor diagonal in mm = 9.09 mm

Crop factor =	43.27	= 4.76
	9.09

S100 crop factor

Sensor diagonal in mm = 9.41 mm

Crop factor =	43.27	= 4.6
	9.41

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).

DC220 equivalent aperture

Crop factor = 4.76
Aperture = f4.0 - f4.8

35-mm equivalent aperture = (f4.0 - f4.8) × 4.76 = f19 - f22.8

S100 equivalent aperture

Crop factor = 4.6
Aperture = f2.0 - f5.9

35-mm equivalent aperture = (f2.0 - f5.9) × 4.6 = f9.2 - f27.1
