Abstract:
1. A video signal coding apparatus comprising: an imaging device which generates an electric signal by performing photoelectric conversion of light from a subject; a video signal generation unit configured to generate a video signal by performing predetermined image processing on the electric signal generated by the imaging device; and a coding unit configured to code the video signal, wherein the coding unit includes: a coding processing unit configured to code, slice-by-slice, a current picture indicated by the video signal, to generate coded data; a coding information management unit configured to manage, slice-by-slice, coding information indicating a feature of the coded data; an integration unit configured to integrate per-slice code amounts of the coded data equivalent to one current picture, to calculate a code-integrated value indicating a code amount of the coded data equivalent to one picture; a coding result determination unit configured to determine whether or not the code-integrated value is greater than a predetermined first threshold, and determine that re-coding processing on the current picture is necessary when determining that the code-integrated value is greater than the first threshold; and a re-coding control unit configured to specify a re-coding target slice based on the coding information when the coding result determination unit determines that the re-coding processing is necessary, the re-coding target slice being a target of the re-coding processing, and the coding processing unit is further configured to perform the re-coding processing on the re-coding target slice specified by the re-coding control unit.
