Software Technology for Calibration module for image sensor, image sensor and method for calibrating crosstalk within image sensor

Samsung Electronics Co., Ltd. (Gyeonggi-do, KR)

An image sensor including the pixel array comprising multiple sub-pixels placed across a variety of rows as well as a plurality of columns, as well as a k number of sub-pixels that represent one color pixel with each other, in which k is an integer that is greater than or equal to four. A calibration circuit could be installed. The calibration circuitry can be used to generate digital image signals from pixel signals. It may be able to store coefficient sets that are corresponding to various colors as well as apply the color enhancement to the digital signal, and calculate the color temperature.

1. Technical Field

Examples of embodiments concern image sensors, specifically, calibration software for image sensors images, image sensors and methods of calibrating crosstalk in the image sensors.

2. Description of Related Art

An electronic device known as an image sensor converts a photo (e.g. light) that is reflected back by the subject into an electrical signal. Thus, image sensors are used extensively in electronic devices that are portable, such as digital cameras mobile phones, and other. Image sensors can generally be divided into two kinds: charged coupled device (CCD), image sensors, and complementary metal oxide semiconductors (CMOS) images sensors. CCD image sensors are more expensive than the CMOS sensors. CCD image sensors have many advantages, such as less manufacturing costs, lower energy consumption and the ease of integration with peripheral circuits. Image sensors with various configurations have been utilized in recent years.

How to Search for Patents

• Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
• Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
• European Patent Office (EPO) provides esp@cenet to access a network of Europe’s patent databases with access to machine translation of European patents. 
• Japan Patent Office (JPO) – with access to machine translations of Japanese patents.
• World Intellectual Property Organization (WIPO) offers PATENTSCOPE with a full-text search of published international patent applications and machine translations for some documents, as well as a list of international patent databases.
• Korean Intellectual Property Rights Information Service (KIPRIS)
• State Intellectual Property Office (SIPO) with machine translation of Chinese patents.
• Other International Intellectual Property Offices with online patent databases include Australia, Canada, Denmark, Finland, France, Germany, Great Britain, India, Israel, Netherlands, Norway, Sweden, Switzerland, and Taiwan.
• Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.

To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
