Abstract

ORIENTAÇÃO AUTOMÁTICA DA CÂMERA E AJUSTE DE CONFIGURAÇÕES. A presente invenção refere-se a um dispositivo de captura e processamento de imagem que captura uma imagem. Com base na imagem e/ou em uma ou mais imagens adicionais, o dispositivo de captura e processamento de imagem gera e emite orientações para otimizar a composição da imagem, configurações de captura de imagem e/ou configurações de processamento de imagem. A orientação pode ser gerada com base na determinação de uma direção para a qual um objeto da imagem está voltado, com base nas medições do sensor que indicam que um horizonte pode ser distorcido, outra imagem da mesma cena capturada usando uma lente grande angular, outra imagem do mesmo objeto, outra imagem de um objeto diferente e/ou saídas de um modelo de aprendizado de máquina treinado usando um conjunto de imagens. O dispositivo de captura e processamento de imagem pode aplicar automaticamente certos aspectos da orientação gerada, como configurações de captura de imagem e/ou configurações de processamento de imagem.
