Abstract:
1. A portable terminal apparatus including a transmission section for transmitting a plurality of pieces of image data to an image output apparatus that outputs image data, said portable terminal apparatus comprising: an image capture section capable of consecutively carrying out image capture a plurality of times with respect to a same image capture object; and a captured image determination section for determining whether or not captured image data meets a given condition, said captured image data being obtained by carrying out the image capture by the image capture section, the given condition including at least the following condition A: condition A: (a) whether an exclusive OR is true for (i) a first binarized image in which a captured image indicated by said captured image data is binarized in accordance with whether each pixel in the captured image is a white pixel having, as features indicative of a degree of luminance of said each pixel, features not less than a first threshold and (ii) a second binarized image in which the captured image is binarized in accordance with whether said each pixel is a white pixel having, as the features indicative of the degree of the luminance of said each pixel, features not less than a second threshold, the second threshold being smaller than the first threshold, or alternatively, (b) whether an exclusive OR is true for (i) a third binarized image in which the captured image is binarized in accordance with whether said each pixel is a black pixel having, as the features indicative of the degree of the luminance of said each pixel, features not more than a third threshold and (ii) a fourth binarized image in which the captured image is binarized in accordance with whether said each pixel is a black pixel having, as the features indicative of the degree of the luminance of said each pixel, features not more than a fourth threshold, the fourth threshold being greater than the third threshold, in a case where the captured image determination section determines that said captured image data meets the given condition, the image capture section consecutively carrying out image capture with respect to the image capture object under a plurality of different exposure conditions from an exposure condition set for carrying out the image capture for obtaining said captured image data, and the transmission section transmitting, to the image output apparatus, captured image data obtained by carrying out the image capture with respect to the image capture object under the plurality of different exposure conditions.
