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 of C-1400XL is approx. 32% higher than pixel pitch of E-100 RS.

Pixel area

41.6 µm²

23.72 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: 17.88 µm² (75%)

A pixel on Olympus C-1400XL sensor is approx. 75% bigger than a pixel on Olympus E-100 RS.

Pixel density

2.41 MP/cm²

4.22 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: 1.81 µm (75%)

Olympus E-100 RS has approx. 75% higher pixel density than Olympus C-1400XL.

Diagonal

Diagonal is calculated by the use of Pythagorean theorem:

Diagonal = √

w² + h²

where w = sensor width and h = sensor height

Olympus C-1400XL diagonal

The diagonal of C-1400XL sensor is not 2/3 or 0.67" (16.9 mm) as you might expect, but approximately two thirds of that value - 11 mm. If you want to know why, see sensor sizes.

w = 8.80 mm
h = 6.60 mm

Diagonal = √

8.80² + 6.60²

= 11.00 mm

Olympus E-100 RS diagonal

The diagonal of E-100 RS sensor is not 1/2 or 0.5" (12.7 mm) as you might expect, but approximately two thirds of that value - 8 mm. If you want to know why, see sensor sizes.

w = 6.40 mm
h = 4.80 mm

Diagonal = √

6.40² + 4.80²

= 8.00 mm

Surface area

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

C-1400XL sensor area

Width = 8.80 mm
Height = 6.60 mm

Surface area = 8.80 × 6.60 = 58.08 mm²

E-100 RS sensor area

Width = 6.40 mm
Height = 4.80 mm

Surface area = 6.40 × 4.80 = 30.72 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

C-1400XL pixel pitch

Sensor width = 8.80 mm
Sensor resolution width = 1365 pixels

Pixel pitch =	8.80	× 1000	= 6.45 µm
	1365

E-100 RS pixel pitch

Sensor width = 6.40 mm
Sensor resolution width = 1315 pixels

Pixel pitch =	6.40	× 1000	= 4.87 µm
	1315

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

C-1400XL pixel area

Pixel pitch = 6.45 µm

Pixel area = 6.45² = 41.6 µm²

E-100 RS pixel area

Pixel pitch = 4.87 µm

Pixel area = 4.87² = 23.72 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

C-1400XL pixel density

Sensor resolution width = 1365 pixels
Sensor width = 0.88 cm

Pixel density = (1365 / 0.88)² / 1000000 = 2.41 MP/cm²

E-100 RS pixel density

Sensor resolution width = 1315 pixels
Sensor width = 0.64 cm

Pixel density = (1315 / 0.64)² / 1000000 = 4.22 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

C-1400XL sensor resolution

Sensor width = 8.80 mm
Sensor height = 6.60 mm
Effective megapixels = 1.40

r = 8.80/6.60 = 1.33

X = √	1.40 × 1000000	= 1026
	1.33

Resolution horizontal: X × r = 1026 × 1.33 = 1365
Resolution vertical: X = 1026

Sensor resolution = 1365 x 1026

E-100 RS sensor resolution

Sensor width = 6.40 mm
Sensor height = 4.80 mm
Effective megapixels = 1.30

r = 6.40/4.80 = 1.33

X = √	1.30 × 1000000	= 989
	1.33

Resolution horizontal: X × r = 989 × 1.33 = 1315
Resolution vertical: X = 989

Sensor resolution = 1315 x 989

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

C-1400XL crop factor

Sensor diagonal in mm = 11.00 mm

Crop factor =	43.27	= 3.93
	11.00

E-100 RS crop factor

Sensor diagonal in mm = 8.00 mm

Crop factor =	43.27	= 5.41
	8.00

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).

C-1400XL equivalent aperture

Crop factor = 3.93
Aperture = f2.8 - f3.9

35-mm equivalent aperture = (f2.8 - f3.9) × 3.93 = f11 - f15.3

E-100 RS equivalent aperture

Crop factor = 5.41
Aperture = f2.8 - f8.0

35-mm equivalent aperture = (f2.8 - f8.0) × 5.41 = f15.1 - f43.3
