Show answerHide answer

Correct answer: (C) transformation from one image to otherएक छवि से दूसरी छवि में परिवर्तन

Explanation

Morphing is a special effect that smoothly transforms one image or shape into another through a series of intermediate frames.Morphing एक विशेष प्रभाव है जो मध्यवर्ती फ़्रेमों की शृंखला से एक छवि या आकृति को सहजता से दूसरी में बदल देता है।

Which one of the following is the characteristic of a multimedia system?निम्नलिखित में से कौन एक मल्टीमीडिया प्रणाली की विशेषता है?
  1. AHigh storageउच्च भंडारण
  2. BHigh data rateउच्च डेटा दर
  3. CBoth High storage and high data rateदोनों उच्च भंडारण और उच्च डेटा दर
  4. DNone of theseइनमें से कोई नहीं
Show answerHide answer

Correct answer: (C) Both High storage and high data rateदोनों उच्च भंडारण और उच्च डेटा दर

Explanation

Multimedia data such as audio, video and images is large, so it needs high storage capacity and high data rates for transmission and playback.ऑडियो, वीडियो और इमेज जैसा मल्टीमीडिया डेटा बड़ा होता है, इसलिए उसे अधिक स्टोरेज क्षमता और प्रसारण व प्लेबैक के लिए उच्च डेटा दर चाहिए।

Q3Bihar STET 2024 Paper II Computer Science, 11 Jun 2024, Shift 2 (3:00 PM)
Joint Photographic Experts Group (JPEG) is used to compress___________संयुक्त फोटोग्राफिक विशेषज्ञ समूह (JPEG) का उपयोग ___________ को संपीड़ित करने के लिए किया जाता है
  1. Avideosवीडियो
  2. Bmusicसंगीत
  3. Cimagesछवियाँ
  4. Dframesफ्रेम
Show answerHide answer

Correct answer: (C) imagesछवियाँ

Explanation

JPEG is a (mostly lossy) compression standard for still images such as photographs.JPEG फ़ोटोग्राफ़ जैसी स्थिर छवियों के लिए (अधिकतर lossy) संपीड़न मानक है।

Q4Bihar STET 2024 Paper II Computer Science, 11 Jun 2024, Shift 2 (3:00 PM)
___________ animation is used to animate things that are smaller than life size.___________ एनीमेशन का उपयोग उन चीजों को चेतन करने के लिए किया जाता है जो जीवन के आकार से छोटी हैं।
  1. AImmersiveइमर्सिव
  2. BClaymotionक्लेमोशन
  3. CStop motionस्टॉप मोशन
  4. DAugmentedसंवर्धित
Show answerHide answer

Correct answer: (C) Stop motionस्टॉप मोशन

Explanation

Stop-motion animation photographs small physical models (clay figures, puppets) frame by frame, moving them slightly between shots. It is used for objects smaller than life size.Stop-motion animation में छोटे भौतिक मॉडलों (मिट्टी की आकृतियाँ, कठपुतलियाँ) की फ़्रेम-दर-फ़्रेम तस्वीरें ली जाती हैं, और हर शॉट के बीच उन्हें थोड़ा हिलाया जाता है। इसका उपयोग वास्तविक आकार से छोटी वस्तुओं के लिए होता है।

Explanation

Animation is a sequence of drawn images shown in quick succession to simulate motion of objects.

Q6Bihar STET Paper 2 Computer Science (Class 11-12), 12 Sep 2023, Shift 2
Which of the following is an example of Digital Image Processing?
  1. AComputer Graphics
  2. BPixels
  3. CCamera Mechanism
  4. DAll of the mentioned
Show answerHide answer

Correct answer: (D) All of the mentioned

Explanation

The key treats computer graphics, pixel-based images and camera (image acquisition) mechanisms as all related examples of digital image processing, so "all of the mentioned" is chosen.

Q8Bihar STET Paper 2 Computer Science (Class 11-12), 12 Sep 2023, Shift 2
Which gray-level transformation increases the dynamic range of gray-level in the image?
  1. ANegative transformations
  2. BContrast stretching
  3. CPower-law transformations
  4. DNone of the mentioned
Show answerHide answer

Correct answer: (B) Contrast stretching

Explanation

Contrast stretching expands a narrow range of input gray levels to cover the full range, increasing the dynamic range of the image.

Correct answer: (A) Short Message Service p { font–family: Arial; }Short Message Service p { font–family: Arial; }

Explanation

SMS stands for Short Message Service, the standard text-messaging service on mobile networks. The CSS fragments in the options are extraction noise.SMS का अर्थ Short Message Service है, जो मोबाइल नेटवर्क पर मानक टेक्स्ट-संदेश सेवा है। विकल्पों में दिखे CSS अंश निष्कर्षण का शोर हैं।

Q11Bihar STET 2025 Paper II Computer Science, 4 Nov 2025, Shift 2 (2:00 PM)
The quality of ___ remains unchanged even if the size is increased or decreased.आकार बढ़ने या कम होने पर भी ___ की गुणवत्ता अपरिवर्तित रहती है।
  1. AVector graphicsवेक्टर ग्राफिक्स
  2. BIllustrationsरेखांकन
  3. CPhotographsफोटो
  4. DLine imagesरेखा चित्र
Show answerHide answer

Correct answer: (A) Vector graphicsवेक्टर ग्राफिक्स

Explanation

Vector graphics store shapes as mathematical paths, not pixels, so they can be scaled up or down with no loss of quality. Raster images such as photographs become pixelated when enlarged.Vector graphics आकृतियों को गणितीय पथ के रूप में संग्रहीत करते हैं, पिक्सेल के रूप में नहीं, इसलिए उन्हें गुणवत्ता खोए बिना बड़ा-छोटा किया जा सकता है। फोटो जैसी raster इमेज बड़ी करने पर pixelated हो जाती हैं।

Q12Bihar STET Paper 2 Computer Science (Class 11-12), 12 Sep 2023, Shift 1

  2. BCharacterअक्षर
  3. CPixel valueपिक्सेल मान
  4. DNone of the aboveइनमें से कोई नहीं
Show answerHide answer

Correct answer: (C) Pixel valueपिक्सेल मान

Explanation

In a digital image, each pixel value (for example an RGB triple) stores one particular colour.डिजिटल इमेज में हर पिक्सेल मान (जैसे RGB त्रिक) एक विशेष रंग संग्रहीत करता है।
