Patent ID: 7711877

Claim:
An image sensing device comprising: an image sensing unit that senses a moving image and a still image; an interface unit that is connected to an external device; a control endpoint that receives from the external device a command requesting transfer of the still image; an isochronous endpoint that transfers the moving image sensed by the image sensing unit to the external device; a bulk endpoint that transfers the still image sensed by the image sensing unit to the external device; an interrupt endpoint that transfers first error information and second error information to the external device, the first error information including information indicating that a first error has occurred during sensing of the still image, and the second error information including information indicating a second error has occurred during transfer of the still image and information indicating a status of the image sensing device when the second error has occurred; and an interface unit controller that transfers the first error information to the external device through the interrupt endpoint if the first error has occurred during sensing of the still image, and transfers the second error information to the external device through the interrupt endpoint if the second error has occurred during the transfer of the still image.
