VividView

VividView is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand VividView rather than just read about it. In short: VividView Processor is the world's first LSI for improving visibility in displays when exposed to direct sunlight, while reducing power consumption at the same time. The technology was developed by Fujitsu Ten in cooperation with Fujitsu Semiconductor Limited and Fujitsu Laboratories.

Key takeaways

VividView belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect VividView to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of VividView from memory before moving on to harder problems.

Reference excerpt

VividView Processor is the world's first LSI for improving visibility in displays when exposed to direct sunlight, while reducing power consumption at the same time. The technology was developed by Fujitsu Ten in cooperation with Fujitsu Semiconductor Limited and Fujitsu Laboratories.

Features of VividView Processor 3 Highly visible display even in direct sunlight Energy conservation through backlight control Sharp, clear, and vivid display of images

VividView technology overview

Color correction in direct sunlight Immediate correction of tone and saturationFirst the image is analyzed and differences in tone are assigned to each area of the image. Then, "pinpoint correction" magnifies the contrast in even the brightest regions, and "tone correction" adjusts dark areas to a lighter tone that will stand out better. Finally, "saturation correction" limits the dilution of color and brightens the image. The combination of this technology improves visibility through the immediate and automatic correction of contrast and saturation in dark areas. Adjustment of correction strength based on the brightness of direct sunlightA sensor detects the brightness of sunlight, which can fluctuate for a variety of reasons (season, time of day, location). Correction strength is adjusted based on brightness level, to achieve optimal image correction according to the degree of deterioration in image quality. A rapid response allows adjustments to be made even during repeated and drastic changes in bright sunlight in a short period of time.

Backlight control Power consumption of display reduced 54% maximum, 24% average Energy conserved in backlight while limiting deterioration in image qualityImage data is analyzed for each scene to provide optimal brightness: low-level brightness for dark images, and higher-level brightness for light images. The brightness level of the image data is corrected according to the brightness of the backlight, to maintain the same appearance as the original image.

Worked examples

Example 1 — a first encounter with VividView

Start with the simplest possible case. Write down what VividView claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to VividView before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about VividView ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of VividView

In research: VividView appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses VividView in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: VividView is common in secondary-school and first-year university syllabi. It links to neighbouring topics Display technology, so understanding it makes those chapters shorter.
In everyday life: Look for VividView outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is VividView in simple terms?

Why does VividView matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study VividView?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
