and responsive to the enlarged portion including a horizontal dividing line, pixels located along the horizontal dividing line are not warped to above or below the horizontal dividing line. ### Claim 6 (depends on 1) The image capture device of claim 1, wherein the extent of the visual content within the enlarged portion is presented using a non-linear projection to cause straight lines to appear curved in the enlarged portion, and other extent of the visual content outside the enlarged portion is presented using a linear projection to cause straight lines to appear straight outside the enlarged portion. ### Claim 7 (depends on 1) The image capture device of claim 1, further comprising a second display carried on a second side of the housing, wherein the portion-enlarged preview of the visual content is not presented on the second display during presentation of the portion-enlarged preview of the visual content on the first display. ### Claim 8 (depends on 7) The image capture device of claim 7, wherein the second display is deactivated during the presentation of the portion-enlarged preview of the visual content on the first display. ### Claim 9 (depends on 1) The image capture device of claim 1, wherein the portion-enlarged preview of the visual content is presented on the first display responsive to a face or a person being within the visual content captured during the capture duration. ### Claim 10 A method for providing warped previews, the method performed by an image capture device including one or more processors, a housing having multiple sides, an image sensor carried by the housing and configured to generate a visual output signal conveying visual information based on light that becomes incident thereon, the visual information defining visual content, an optical element carried on a first side of the housing, the optical element configured to guide light within a field of view to the image sensor, and a first display carried on the first side of the housing, the method comprising: capturing the visual content during a capture duration; and presenting a portion-enlarged preview of the visual content on the first display, the portion-enlarged preview of the visual content including an enlarged portion, an extent of the visual content within the enlarged portion warped to increase size of depiction within the enlarged portion by distorting shape of things depicted within the enlarged portion, wherein warping of the visual content within the enlarged portion is constrained to maintain rule of thirds within the portion-enlarged preview of the visual content by not warping pixels located along dividing lines that divide the visual content into thirds. ### Claim 11 (depends on 10) The method of claim 10, wherein the portion-enlarged preview of the visual content includes entirety of the visual content. ### Claim 12 (depends on 10) The method of claim 10, wherein the enlarged portion is a center portion of the portion-enlarged preview of the visual content. ### Claim 13 (depends on 10) The method of claim 10, wherein the visual content includes a face, and position of the enlarged portion within the portion-enlarged preview of the visual content is determined to include the face within the enlarged portion. ### Claim 14 (depends on 10) The method of claim 10, wherein not warping the pixels located along the dividing lines that divide the visual content into thirds includes not changing position of things depicted along the dividing lines, further wherein: responsive to the enlarged portion including a vertical dividing line, pixels located along the vertical dividing line are not warped to left or right of the vertical dividing line; and responsive to the enlarged portion including a horizontal dividing line, pixels located along the horizontal dividing line are not warped to above or below the horizontal dividing line. ### Claim 15 (depends on 10) The method of claim 10, wherein the extent of the visual content within the enlarged portion is presented using a non-linear projection to cause straight lines to appear curved in the enlarged portion, and other extent of the visual content outside the enlarged portion is presented using a linear projection to cause straight lines to appear straight outside the enlarged portion. ### Claim 16 (depends on 10) The method of claim 10, wherein the image capture device further includes a second display carried on a second side of the housing, and the portion-enlarged preview of the visual content is not presented on the second display during presentation of the portion-enlarged preview of the visual content on the first display. ### Claim 17 (depends on 16) The method of claim 16, wherein the second display is deactivated during the presentation of the portion-enlarged preview of the visual content on the first display. ### Claim 18 (depends on 10) The method of claim 10, wherein the portion-enlarged preview of the visual content is presented on the first display responsive to a face or a person being within the visual content captured during the capture duration. ### Claim 19 An image capture device for providing warped previews, the image capture device comprising: a housing having multiple sides; an image sensor carried by the housing and configured to generate a visual output signal conveying visual information based on light that becomes incident thereon, the visual information defining visual content; an optical element carried on a first side of the housing, the optical element configured to guide light within a field of view to the image sensor; a first display carried on the first side of the housing; one or more physical processors carried by the housing, the one or more physical processors configured by machine-readable instructions to: capture the visual content during a capture duration; and present a portion-enlarged preview of the visual content on the first display, the portion-enlarged preview of the visual content including entirety of the visual content, the portion-enlarged preview of the visual content including an enlarged portion, an extent of the visual content within the enlarged portion warped to increase size of depiction within the enlarged portion by distorting shape of things depicted within the enlarged portion, wherein warping of the visual content within the enlarged portion is constrained to maintain rule of thirds within the portion-enlarged preview of the visual content by not warping pixels located along dividing lines that divide the visual content into thirds; wherein the extent of the visual content within the enlarged portion is presented using a non-linear projection to cause straight lines to appear curved in the enlarged portion, and other extent of the visual content outside the enlarged portion is presented using a linear projection to cause straight lines to appear straight outside the enlarged portion. ### Claim 20 (depends on 19) The image capture device of claim 19, wherein not warping the pixels located along the dividing lines that divide the visual content into thirds includes not changing position of things depicted along the dividing lines, further wherein: responsive to the enlarged portion including a vertical dividing line, pixels located along the vertical dividing line are not warped to left or right of the vertical dividing line; and responsive to the enlarged portion including a horizontal dividing line, pixels located along the horizontal dividing line are not warped to above or below the horizontal dividing line.
