Endoscopic apparatus configured to capture an image of in-vivo tissue and configured to perform automatic exposure control and a method for automatic exposure control of an endoscopic apparatus configured to capture an image of in-vivo tissue. The method comprising: (i) capturing image data on an image sensor using an exposure period, that image data comprising: an indication of brightness captured by each pixel of the image sensor； (ii) analysing the indication of brightness of each pixel to determine whether the captured image data is saturated； and when it is determined that the captured image data is saturated: (iii) reducing the exposure period by a first increment, and repeating steps (i) and (ii) until it is determined that the captured image data is not saturated； when it is determined that the captured image data is not saturated: (iv) analysing the indication of brightness of each pixel to determine whether a threshold indicative of use of a selected proportion of an available dynamic range of the image sensor has been reached； and when it is determined that the threshold has not been reached: increasing the exposure period by a second increment； wherein the first increment has a magnitude at least three times that of the second increment. Aspects and embodiments described may provide a means to capture useful images of in-vivo tissue, such images typically being prone to saturation as a result of the disparity of reflectivity of tissue on a small scale.L'invention concerne un appareil endoscopique configuré pour capturer une image de tissu in vivo et exécuter une commande d'exposition automatique. L'invention concerne également un procédé de commande d'exposition d'un appareil endoscopique configuré pour capturer une image de tissu in vivo. Le procédé consiste à : (i) capturer des données d'image sur un capteur d'image durant une période d'exposition, lesdites données d'image comprenant : une indication de luminosité capturée par chaque pixel du capteur d
