The RAW image from the image sensor needs significant processing to be converted into a high-quality image. Image signal processing (ISP) is used in such instances. An ISP is a dedicated processor that converts the camera sensor-generated raw data into a functioning image format. Figure 5 shows an image signal processing pipeline with distinct processing stages, which play a crucial role in making a premium quality image. The ISP fulfills many of the following steps to supply a high-quality image for a specific camera sensor and use-case:

Ich benutze schon seit Jahren diese Bürstenköpfe. Sie gefallen mir sehr gut. Ein Kritikpunkt habe ich allerdings, die Vorgängermodelle der Bürsten waren, nicht von der Oberfläche her matt, sondern eher glatt glänzend. Diese Matte Oberfläche der neuen Bürstenköpfe fühlt sich unangenehm im Mund an. Die farbliche Kennzeichnung der einzelnen Bürstenköpfe beinhaltet jetzt auch die Farbe schwarz. Das ist ein Problem, weil nach einer gewissen Zeit ist mir aufgefallen, dass die Bürstenköpfe im Inneren ein schwarzen Film bilden. Ich vermute mal die Oberfläche fängt an zu schimmeln. Auf dieser schwarzen Oberfläche ist dieser Bio Film, der für mich immer als Indikator gilt, die Bürste zu tauschen nicht mehr sichtbar und das ist schlecht. Ich würde es begrüßen, wenn man die schwarze Kennzeichnung zukünftig aus dem Programm nimmt.

A CMOS image sensor has a photodiode and a CMOS transistor switch for each pixel in the pixel array and permits individual amplification of the pixel signals. A matrix of switches enables the pixel signals to be sequentially and directly accessed. Most modern sensors are of CMOS variety. A microlens implemented over the Bayer filter helps each pixel capture the maximum quantum of light.  The pixels are not precisely mutually positioned as a tiny gap exists between them. Any light which falls into such a gap is wasted light and will not be used for exposure. These microlenses want to erase this light waste by directing the light, which falls between the two pixels.

2. White Balancing: White balance (WB) is a process to remove unrealistic color casts so that white objects in real life are rendered white in an image. Human eyes are excellent at judging white color under different light sources. Still, digital cameras develop complications with auto white balance (AWB) and may create displeasing blue, orange, or sometimes green color casts. Correct camera white balance must include the "color temperature" of that particular light source, citing the relative coolness or warmth of white light. The white balance, other than color temperature, employs another technique termed green-magenta shift. It is unnecessary to adjust the green-magenta shift under ordinary daylight. Artificial lighting (like fluorescent lighting) may need considerable green-magenta adjustments to WB.

4. Color Transformation: Color transformation (aka color space conversion) is the translation of color representation from a basis to another. It generally happens in converting an image represented in one color space to yet another color space.  The aim is to make that translated image appear identical (or closest to it) to the original. Color space denotes a particular color organization that permits reproducible analog and digital representations of color. A color space can be arbitrary, with specific colors assigned to physical color swatches set and analogous assigned color numbers or names (the Pantone collection), or be structured mathematically (the NCS System,sRGB, and  Adobe RGB).

3. Demosaicing: Demosaicing is an image processing algorithm used to reconstruct full-resolution color images from sampled data acquired from an image sensor that uses a color filter array (CFA).  It is also known as CFA interpolation or color reconstruction. Demosaicing methods are divided into three groups. Heuristic approaches comprise the first group. The second group expresses demosaicing as a restoration complication. The third group constitutes a generalization which employs a spectral filtering model. The demosaicing techniques are usually either proprietary or under patents. All demosaicing methods utilize pixel neighborhood information to estimate non-measured pixel colors' values.

Wir verwenden seit ein paar Jahren die TIO Aufsteckköpfe für unsere elektrische Zahnbürsten von Oral-B und sind sehr zufrieden. Anfangs hatten wir das Gefühl, dass der Kopf ein wenig größer ist als die Oral-B-Aufsteckköpfe aber man gewöhnt sich schnell daran. Schade, dass es nur 4 Farbringe (dunkelgrün, rosa, hellblau, türkis) und nicht weitere Farben dabei sind, aber dass ist überhaupt nicht schlimm. Sind wirklich zum Empfehlen. Gabriel

1. Preprocessing: The sensor generated raw data must be processed before full-color image production to eliminate noise (among other artifacts) beside a color processing pipeline to generate an accurate or a photogenic representation of that captured scene. A standard preprocessing procedure is defective pixel correction. Certain sensor photo-elements can be defective and, if uncorrected, crops up as confetti-like errors post demosaicing. The estimation of such missing or defective pixels is done by interpolating the accurately recorded data in their neighborhood. In some cases, preprocessing also includes linearization, dark current compensation, and flare compensation.

An image sensor is made up of an array of pixels, and each pixel contains a photodetector that converts incident light into photocurrent. It includes some of the readout circuits needed to convert the photocurrent into voltage and to read it off the array, as shown in figure 2. The percentage of area occupied by the photodetector in a pixel is known as the fill factor. The rest of the readout circuits are located at the array's periphery and multiplexed by the pixels. Pixel circuits are mainly divided into active pixels (APS) and passive pixels (PPS). APS are sensors that implement a buffer per pixel simply as a source-follower. Passive pixels (PPS) are based on photodiodes without internal amplification.

6. Display, Compress, and Store: Image data must be remolded into the appropriate color space dependent on reproduction media like printer type or computer monitor. A CRT monitor is a good example in this context. In this case, the data must be changed into an 8-b format, anticipating the display model (gamma values, color temperature, and offsets). When it comes to dye-sublimation printer (four-color, subtractive color), the data is changed into a CMYK color space using the correct color reproduction model.

The Bayer filter that produced a colored image is an integrated camera part. The color gets filtered at each photosite and traps alternating red, green, and blue color photosites so that green photosites get recorded twice concerning the other two colors. The filter pattern is thus 50 percent green, 25 percent red, and 25 percent blue. It is then represented as BGGR, RGBG, GRGB, or RGGB. This happens as the human eye is more prone to green color. The values from such photosites are then judiciously combined to generate full-color pixels using the "demosaicing" process.  These values are further processed via an image signal processing pipeline technique to achieve superior quality. A color photosites' Bayer filter pattern side view is shown in Figure 4.

5. Postprocessing: Postprocessing is a requisite as every individual previous step may inject objectionable artifacts. A good example is a demosaicing step inserting a zipper artifact beside strong intensity edges. The common postprocessing steps include removal, coring, and edge enhancement. These methods are mostly heuristic-based and need to be substantially fine-tuned. The human eye is highly sensitive to sharp edges, noticeably to the vertical and horizontal edges compared to diagonal ones, and even numb to edges in the other directions. The majority of camera manufacturers use an edge-enhancement step, such as unsharp masking, to enhance image appeal by reducing the image's low-frequency content in the image. Coring removes insignificant image detail information.

An image sensor module includes lens assembly, photodetectors, amplifiers, and sensors on a single PCB and connected to an external SoC for further image processing. These modules can integrate multiple attributes on a single silicon die since the pixel array includes autofocus (AF) drivers, lens shading correction (LSC) algorithms, and also innovative solutions, like high dynamic range (HDR) technology with substantial system on chip (SoC) prowess.

Camerasensor

202378 — A camera sensor is a light-sensitive device that captures the light that enters the camera and converts it into an electronic signal.

With the opening of the camera shutter, light (photons) passes through a lens (imaging optics) and color filter array, and finally, hit the image sensors (photodiodes). The photons are converted into an electrical signal again, amplified and reconverted into digital form using an ADC. After exposure, the photons that reach each photosite generate an electrical signal, varying in strength depending on the photons captured inside the cavity. The information is sewn together to obtain a Raw image. Figure 1 shows an imaging system pipeline from capturing the scene to image enhancement and compression.

Billions of images get uploaded daily. It's now a cliché to freeze a moment in time, capture life by digital means, and cherish the memory for years to come. Have you ever paused to think of how a camera detects an image and processes it in digital form or how images become clear and sharp in varied lighting conditions? Camera performance (read: superior image quality) is crucial for some use-cases like automotive and artificial intelligence.  This blog explains the technology inside the camera and how its sensing element (image sensor) works.

Understanding CMOS image sensor

When light hits the chip In the CCD image sensor, it transforms into a small electrical charge and is stored in each photosensor. The charges present in the pixel line closest to the output amplifiers get amplified and reworked to an output, followed by the individual line of pixels shifting their charges one line nearer to the amplifier. The process is subsequently repeated by moving the charge until all the pixels lines changed into an output. An analog-to-digital converter (ADC) subsequently turns an individual pixel's value into a digital form by quantifying the volume of charge at each photosite and then turning that measurement into its binary form.

Image sensors are fabricated using metal-oxide-semiconductor technology and can be categorized into two types as per their pixel element: Charged Couple Device (CCD) and CMOS sensor (aka active pixel sensor). CCD is based on the MOS capacitor, whereas CMOS is based on the MOSFET amplifier.

Current implementations store the images in either a proprietary file format or a recently developed tagged image file format for electronic photography (TIFF/EP). The TIFF/EP files are standard TIFF files, but supplementary file tags store linearization function, camera settings details, spectral sensitivities, color transform matrix, and illuminant used information. The image data is generally stored in a mosaicked form. Consumer cameras mostly use EXIF format, as it is compact and easy to implement in hardware. Another alternative is the baseline JPEG algorithm.

Raw image sensor modules offer raw image output of uncompressed and unprocessed data. An external ISP processor is thus required for further image processing to produce a quality image. In contrast, the YUV image sensor module packs an inbuilt ISP pipeline and gives YUV image data as output. Since the image pipeline is hardware-implemented, completion of front-end image processing does not impose any processing burden on the main application processor. In such cases, the Host SoC has no ISP requirement, and data is directly compressed, stored in memory, or streamed out conditional on application.
