Patent number: 11956411Abstract: An image signal processor includes a register and a disparity correction unit. The register stores disparity data obtained from a pattern image data that an image senor generates, and the image sensor includes a plurality of pixels, and each of the pixel includes at least a first photoelectric conversion element and a second photoelectric conversion element. The image sensor generates the pattern image data in response to a pattern image located at a first distance from the image sensor. The disparity correction unit corrects a disparity distortion of an image data based on the disparity data to generate a result image data, and the image senor generates the image data by capturing an object.Type: GrantFiled: September 28, 2022Date of Patent: April 9, 2024Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Hee Kang, Young-Jun Song, Dong-Ki Min, Jong-Min You, Jee-Hong Lee, Seok-Jae Kang, Taek-Sun Kim, Joon-Hyuk Im

Patent number: 11927886Abstract: Disclosed are a substrate treating apparatus and a substrate treating method. According to an embodiment of the inventive concept, the purge operation of the purge nozzle is performed while the nozzle arm is moved from the first substrate support member to the second substrate support member, it hardly influences the operation of treating the substrate while the nozzle arm is moved from the first substrate support member to the second substrate support member. According to an embodiment of the inventive concept, the substrate treating apparatus may perform an operation of purging the photosensitive liquid nozzle while the treatment liquid supply unit performs a process of supplying the photosensitive liquid to the substrate. Accordingly, because the operation of purging the photosensitive liquid nozzle is performed at the same time when the substrate treating apparatus performs a process, productivity may be improved.Type: GrantFiled: March 5, 2021Date of Patent: March 12, 2024Assignee: SEMES CO., LTD.Inventors: Doo Young Oh, Joon Jae Lee
